Description

Technical Field

[0001] This disclosure relates to the field of puzzle game devices, and more specifically to a board game device. Background Technology

[0002] Traditional board games, such as Flip Chess, rely on a physical board, physical pieces, and manual movement of those pieces. These physical pieces are easily lost and extremely inconvenient to carry. Furthermore, traditional board games cannot be played anytime, anywhere, as they require a specific playing area. In addition, existing board games lack human-computer interaction, making them tedious and failing to maintain player interest for extended periods. These problems all contribute to a poor user experience and low satisfaction. Moreover, these traditional board games suffer from low accuracy in judgment—players must manually determine the legal placement and flipping direction of each piece, which is prone to human error, especially in complex game situations.

[0003] While existing electronic flip chess apps can automatically execute flip logic, their interaction methods are simplistic, merely simulating a physical chessboard through a two-dimensional interface, lacking strategic guidance for novice players. Furthermore, their flip animations are stiff and fail to accurately reproduce the physical trajectories of real pieces, impacting game immersion. In addition, these electronic flip chess games largely rely on touchscreen operation and typically require mobile devices. Since flip chess users are mostly teenagers, this increases their dependence on mobile devices such as phones and tablets, potentially leading to eye strain or vision damage.

[0004] To address at least one of the problems of existing technologies, a novel chess-playing device is needed that does not use physical chess pieces, is portable, and can be used in any scenario. Furthermore, this device should have a simple structure, be as compact as possible, and have the lowest possible cost while meeting design and manufacturing feasibility requirements. It should also possess excellent human-computer interaction to enhance user interest, avoid eye strain, and improve user experience and satisfaction. Summary of the Invention

Alternatively or additionally, the chessboard 100 can form the plurality of squares 110 by projection or illumination from other components (such as the uniform light film 330, which will be detailed below). According to an exemplary embodiment, the chess-playing device 10 also includes a body 20, on which the chessboard 100 is supported or mounted. More specifically, the body 20 may be provided with a receiving cavity 23, which may accommodate other components of the chess-playing device 10, such as a battery module 900. According to one exemplary embodiment, the chessboard 100 constitutes at least a portion of the cover 30 that closes the opening of the receiving cavity.

[0176] According to some embodiments, the plurality of chess squares 110 of the chess-playing device 10 are divided into enabled chess squares 110a and disabled chess squares 110b according to their state, such as Figure 5-7 As shown in 9, 11-17. More specifically, in the corresponding game phase, the activated square 110a includes the first-party activated square 110a1 and the second-party activated square 110a2, both in an activated state. More specifically, the first-party activated square 110a1 belongs to the first party (first mover) in the game phase of the chess device 10, and the second-party activated square 110a2 belongs to the second party (second mover) in the game phase of the chess device 10. More specifically, "activated state" is the same as "occupied state," meaning a square in the activated state has been occupied by one party. More generally, "occupied square" is a square that has already been occupied by one party.

[0177] According to some embodiments, the chess-playing device 10 may further include a conversion module configured to convert one of the inactive squares 110b into a currently active square, which is one of a first-player active square 110a1 and a second-player active square 110a2. More specifically, in the current game step, the conversion module can be operated by the "current player" of either the first or second player to "place a piece" on an inactive square 110b, that is, to convert the inactive square 110b into an active square for the current player. This square in the inactive square 110b that is converted may be called a "selected square," that is, an inactive square 110b selected by the user of the chess-playing device 10 to be "placed" or "converted" into an active square for the current player. According to some embodiments, such as Figure 9-14As shown, the chess-playing device 10 is configured such that when the conversion module operates to convert a selected square into a currently active square, at least one associated opponent active square associated with the selected square is also converted into a currently active square. The opponent active square, in contrast to the "currently active square," is another type of the first active square 110a1 and the second active square 110a2. According to some embodiments, in the current game step, the conversion module can convert the selected square itself into a currently active square, and can also convert or "flip" at least one associated opponent active square associated with the selected square into a currently active square.

[0178] According to some embodiments, the game modes of the chess device 10 include at least one of a single-player game mode and a two-player game mode. The single-player game mode is also referred to as a human-computer game mode, and the two-player game mode is also referred to as a human-to-human game mode. In the context of this document, in the single-player game mode, the "first player" or "first mover" is one of the human and the computer (i.e., the chess device 10 itself), and the "second player" or "second mover" is the other of the human and the computer. In the two-player game mode, the "first player" or "first mover" is one of the two players, and the "second player" or "second mover" is the other of the two players. In the context of this document, the "current player" is the player whose turn it is to move, place a piece, or perform a related operation in the corresponding game step. In the context of this document, a "game segment" is a "round," a "set," or a "time" of play, which can correspond to multiple rounds of alternating actions by the two players from the start to the end of the game. A "game step" includes one player making a move, placing a piece, or performing a related operation.

[0179] According to some embodiments, such as Figure 4 , 8 As shown in 10, 18, 24, 25 and 29-31, the chess-playing device 10 also includes a display module 300. The display module 300 may include a chess square display unit 310 corresponding to each chess square 110. Each chess square display unit 310 may be configured to have an on / off state and provide indication information about the state of the corresponding chess square. According to some embodiments, the material forming at least each chess square 110 of the chessboard 100 is formed of a light-transmitting material to display the indication information shown by the chess square display unit 310. The display module 300 allows for enhanced human-computer interaction and enjoyment, and provides clear and intuitive indications of the current game state to increase user interest. The display module 300 also allows for the elimination of physical chess pieces, thus allowing users to conveniently use the chess-playing device 10 in any location.

[0180] According to some embodiments, the checkerboard display unit 310 is configured to have different illumination states to indicate the corresponding state of the corresponding checkerboard 110. Exemplarily, and not exclusively, the checkerboard display unit 310 is configured to display the various states of the corresponding checkerboard 110 in the illumination state by displaying at least one of brightness, color, pattern, text, letters, numbers, and flashing patterns. More specifically, the checkerboard display units 310 can be controlled independently of each other, for example, by a control module 400. According to one exemplary embodiment, the checkerboard display unit 310 includes LED lights. According to some embodiments, the checkerboard display unit 310 is configured to provide, in the illumination state, a first activation indication message indicating that a first party activates checkerboard 110a1 and a second activation indication message indicating that a second party activates checkerboard 110a2, the second activation indication message being different from the first activation indication message. Figure 5-7 As shown in Figure 9-18, the first activation indication is marked with a purple symbol (①), and the second activation indication is marked with a yellow symbol (②).

[0181] According to some embodiments, such as Figure 3-4 As schematically shown in 8, 10, 18, 24-31, the chess-playing device 10 may further include a control module 400, which may be, for example, or include a dedicated circuit board 410 with dedicated integrated control circuitry. The control module 400 may be communicatively connected to the conversion module and the display module 300 to control the state of the corresponding chess grid display unit 310 of the display module 300 in response to the operation of the conversion module. According to a further embodiment, the conversion module may be configured to generate a sensing signal that can be communicated to the control module 400, which, in response to the generation or receipt of the sensing signal, controls the display module 300 to change the display state of the chess grid display unit 310 associated with the operation of the conversion module. According to some embodiments, the associated chess grid display unit 310 may include a chess grid display unit 310 corresponding to a selected chess grid and the at least one associated opponent-enabled chess grid. According to some embodiments, the associated checkerboard display unit 310 may further include checkerboard display units 310 corresponding to the selected checkerboard 110c and / or all optional checkerboard 110b1, which will be detailed below. According to some embodiments, the lighting elements, such as LEDs, forming the respective checkerboard display units 310 are directly disposed on the circuit board 410 of the control module 400.

[0182] The first variant of chess equipment 10

[0183] According to some embodiments, such as Figure 5-7As shown, the conversion module may include a first move position confirmation unit 500, which is configured to convert a selected square into a currently enabled square. More specifically, the first move position confirmation unit 500 is operable to convert a selected square into a currently enabled square. According to some embodiments, the chess device 10 is configured to, when the first move position confirmation unit 500 operates, also convert at least one associated opponent enabled square into a currently enabled square. According to some embodiments, the control module 400 is configured to be communicatively connected to the first move position confirmation unit 500. According to some embodiments, the control module 400 may be configured to control the display module 300 in response to the operation of the first move position confirmation unit 500, such that the square display unit 310 corresponding to the selected square switches to displaying one of a first enable indication information and a second enable indication information to indicate the conversion of the selected square to a currently enabled square (e.g., from...). Figures 5 to 7 (This transition is shown). According to a further or alternative embodiment, the control module 400 may be configured to control the display module 300 in response to the operation of the first move position confirmation unit 500, such that the grid display unit 310 corresponding to the at least one associated opponent-enabled grid changes from displaying one of a first activation instruction and a second activation instruction to displaying one of the first activation instruction and a second activation instruction to indicate the transition from the at least one associated opponent-enabled grid to the current player-enabled grid. This ensures human-computer interaction and game enjoyment, and realizes the "flipping" action of the opponent's piece after the current player "places a piece," enhancing the game experience.

[0184] For example, in the context of this article (not limited to the embodiment here), if it is the first player's turn to act in the current game, which is equivalent to "placing a piece" or "moving a piece" in the traditional sense, then the first player is the current player, and the first player's activated piece 110a1 is the current player's activated piece, while the second player's activated piece 110a2 is the opponent's activated piece. In this example, such as Figure 5-7As shown, when the current player, i.e. the first player, operates the first move position confirmation unit 500, one of the non-activated squares 110b, i.e. the selected square, is converted into the current player's activated square, i.e., the first player's activated square 110a1. The square display unit 310 corresponding to the selected square then switches to displaying first activation information to indicate the conversion of the selected square to the first player's activated square 110a1. At least one associated opponent's activated square (i.e., the second player's activated square 110a2) associated with the selected square is also converted into the first player's activated square 110a1. The square display unit 310 corresponding to the at least one associated second player's activated square 110a2 switches from displaying second activation indication information to displaying first activation indication information to indicate the conversion of the at least one associated second player's activated square 110a2 to the first player's activated square 110a1; and vice versa.

[0185] According to some embodiments, the first move position confirmation unit 500 is configured to generate a confirmation sensing signal upon operation, and the control module 400 is configured to control the display module 300 to perform the aforementioned operation in response to the generation or receipt of the confirmation sensing signal. According to some embodiments, the conversion module may include the first move position confirmation unit 500 corresponding to each chess square 110. According to some embodiments, the first move position confirmation unit 500 may include a touch control or button electrically connected to the control module 400.

[0186] According to some embodiments, such as Figure 5-7 As shown, an inactive square 110b may include an optional square 110b1. More specifically, in the current game step of a game phase, an inactive square 110b may include an optional square 110b1 and an unselectable square 110b2. An optional square 110b1 is an inactive square 110b that can be converted into an active square for the current player in the current game step. More specifically, an unselectable square 110b2 is a square that cannot be selected in the current game step. More specifically, the selected square is one of the optional squares 110b1. According to some embodiments, each optional square 110b1 is determined by the layout or distribution of the associated first-player active square 110a1 and associated second-player active square 110a2 on the board 100 in the current game step. More specifically, for each optional square 110, there exists at least one associated first-player active square 110a1 and at least one associated second-player active square 110a2 associated with that optional square 110b1. According to some embodiments, the optional grid 110b1 varies in different game steps within a game segment.

[0187] According to some embodiments, the checkerboard display unit 310 is also configured to provide optional indicator information (such as...) in the illuminated state. Figure 5-6(Represented by light blue marked ③) to indicate the corresponding square 110. More specifically, the corresponding inactive square 110b is an optional square 110b1. The optional indication information is different from the first and second enabled indication information. The optional indication information allows users to quickly identify the squares in the current game that can be placed or transformed, helping the player to quickly lock in the possible placement positions, reducing the game difficulty and entry barrier, accelerating the game process, and enhancing human-computer interaction and game fun.

[0188] According to some embodiments, the control module 400 is configured to control the display module 300 in response to the operation of the first move position confirmation unit 500, such that the move display unit 310 corresponding to the selected move changes from displaying optional indication information to displaying one of a first activation indication information and a second activation indication information to indicate the transition from the selected move to the currently activated move (e.g., from...). Figures 5 to 7 This configuration allows the display module 300 to present the dynamic process of the transition from the selected square to the currently enabled square, making it easy for the user to identify which square has been transformed, enhancing human-computer interaction, and more specifically, enhancing the user-friendliness and interactivity of the chess device 10, attracting user attention and increasing user interest. According to some embodiments, the control module 400 is further configured to control the display module 300 in response to the operation of the first move position confirmation unit 500, causing the square display units 310 corresponding to the remaining selectable squares 110b1 (excluding the selected square) to switch from displaying selectable indication information to an off state or a reduced brightness state (e.g., ...). Figure 7 (The remaining optional squares are shown to be off). This configuration prevents irrelevant optional squares 110b1 from causing any visual interference to the transformation process of the selected square and the flipping process of the at least one associated opponent-enabled square, thereby allowing the user's line of sight and attention to be locked on the relevant transformation and flipping squares, quickly judge the current changes in the game, and also allows for reduced power consumption.

[0189] According to some embodiments, the display module 300 is configured to keep the display units 310 corresponding to the non-selectable squares 110b2 (excluding the selectable squares 110b1) in the non-enabled squares 110b in a turned-off state during game steps. This avoids any visual interference from the non-selectable squares 110b2 to other squares and also helps to save power.

[0190] The second variant of chess equipment 10

[0191] According to some embodiments, such as Figure 1-4Figure 10-31 schematically illustrates that the conversion module can be configured to include a move position selection unit 600, which is configured to operate to select one of the inactive squares 110b. This operation of the move position selection unit 600 can be referred to as a "selection operation". According to some embodiments, an inactive square 110b selected by the move position selection unit 600 is collectively referred to as "selected square 110c" in this second embodiment. More specifically, the inactive square 110b corresponding to each selection operation of the move position selection unit 600 is referred to as the selected square 110c. According to some embodiments, in game steps of the game phase, the move position selection unit 600 is configured to only "access" or select inactive squares 110b when performing a selection operation, and cannot "access" or select active squares 110a that are in an active state. More specifically, the selected square 110a is not an option for the placement selection unit 600. Therefore, the operation of the placement selection unit 600 will avoid all selected squares 110a and only select one square from the range of non-selected squares 110b. This allows the user's selection operation via the placement selection unit 600 to be more targeted, eliminating unnecessary steps, speeding up the game, and preventing the user from becoming annoyed by cumbersome selection operations.

[0192] According to some embodiments, the conversion module is configured to, when the selection operation of the move position selection unit 600 satisfies the conversion condition, lock the selected square 110c corresponding to the selection operation that satisfies the conversion condition as a selected square, and convert the selected square and the at least one associated opponent-enabled square into the current player-enabled square. According to some embodiments, the conversion condition may be a time threshold condition, such as the move position selection unit 600 not performing any further selection operation within a given time threshold. According to some embodiments, the conversion module further includes an input detection unit (not shown), configured to detect the selection operation of the move position selection unit 600 and determine whether the selection operation satisfies the conversion condition, and, when the conversion condition is met, lock the selected square 110c as a selected square and convert the selected square and the at least one associated opponent-enabled square into the current player-enabled square. According to some embodiments, the conversion condition may include the input detection unit not detecting any further operation by the move position selection unit 600 within a given time threshold. That is, if the move selection unit 600 performs a selection operation to select one of the non-enabled squares 110b (i.e., the selected square 110c), and the move selection unit 600 does not perform another selection operation within a given time threshold (e.g., 5-15 seconds), then the conversion condition is met. According to some embodiments, the input detection unit is communicatively connected to the move selection unit 600. According to some embodiments, the input detection unit is communicatively connected to the control module 400. According to some embodiments, the operation of the move selection unit 600 generates a selection sensing signal, and the input detection unit can determine whether the move selection unit 600 has performed a selection operation based on the generation or receipt of the selection sensing signal. According to some embodiments, the input detection unit may include a timer configured to start timing after the input detection unit detects the selection operation of the move selection unit 600, and generate a confirmation conversion signal when the timing reaches a given time threshold. The input detection unit can convert the selected square and the at least one associated opponent-enabled square to the current opponent-enabled square based on the generation or receipt of the confirmation conversion signal. According to some embodiments, the input detection unit may be an integrated part of the control module 400.

[0193] According to some embodiments, the control module 400 is configured to be communicatively connected to the input detection unit. According to some embodiments, the control module 400 is configured to control the display module 300 in response to the input detection unit determining that a selection operation satisfies a transition condition, such that the grid display unit 310 corresponding to the selected grid switches to displaying one of a first activation indication information and a second activation indication information to indicate the transition from the selected grid to the currently activated grid. More specifically, the control module 400 is configured to control the display module 300 in response to the input detection unit determining that a selection operation satisfies a transition condition, such that the grid display unit 310 corresponding to the at least one associated opponent activated grid switches from displaying another of the first and second activation indication information to displaying one of the first and second activation indication information to indicate the transition from the at least one associated opponent activated grid to the currently activated grid.

[0194] According to some embodiments, the move selection unit 600 may be configured as a knob, button, touch control, or a rotating ring 620, which will be detailed below. According to some embodiments, the chess device 10 may include a single move selection unit operable by each of the two players. According to some embodiments, the chess device 10 may include two move selection units, each operable by one of the two players.

[0195] According to some embodiments, such as Figure 9-18 As schematically shown, the checkerboard display unit 310 can be configured to provide selection indication information (e.g., using...) indicating the selected checkerboard 110c when it is lit up. Figure 9 , 14-17 is marked with a dark blue ④, allowing the user to easily observe which square 110c is currently selected. The selection indication information is different from both the first and second activation indication information. According to some embodiments, "selected square 110c" is defined as the square that the move position selection unit 600 "visits" or "traverses" at the current moment. According to some embodiments, the control module 400 can be communicatively connected to the move position selection unit 600. More specifically, the move position selection unit 600 generates a selection sensing signal during operation, which is communicated to the control module 400, so that the control module 400 can determine which square the move position selection unit 600 is currently operating on, i.e., determine the current selected square 110c. According to some embodiments, the control module 400 can be configured to control the display module 300 in response to the operation of the move position selection unit 600, so that the square display unit 310 corresponding to the selected square 110c displays the selection indication information. For example, the chess square display unit 310 corresponding to the selected chess square 110c can be configured to switch from an off state to displaying selection indication information. According to a further embodiment, the control module 400 can be configured to control the display module 300, more specifically, control the chess square display unit 310 corresponding to the selected chess square to switch from displaying selection indication information to displaying one of a first activation indication and a second activation indication to indicate the transition from the selected chess square to the currently activated chess square, in response to the input detection unit determining that the selection operation of the chess placement selection unit 600 satisfies the aforementioned transition conditions. This configuration allows the display module 300 to present the dynamic process of the transition from the selected chess square to the currently activated chess square, thereby making it easy for the user to confirm which chess square has been transformed, enhancing human-computer interaction, and more specifically, enhancing the user-friendliness and interactivity of the chess device 10, attracting user attention and increasing user interest.

[0196] According to some embodiments, such as Figure 9-10Figures 14-18 schematically illustrate that the inactive square 110b may include an optional square 110b1. More specifically, in the current game step of a game phase, the inactive square 110b may include an optional square 110b1 and an unselectable square 110b2. An optional square 110b1 is a square that can be selected for conversion in the current game step, that is, a square that can be selected in the current move to become the current player's active square. More specifically, the selected square 110c is one of the optional squares 110b1. More specifically, the unselectable square 110b2 is a square that cannot be selected in the current game step. According to some embodiments, the move position selection unit 600 is configured to be operable to select one of the optional squares 110b1 as the selected square 110c described above. According to some embodiments, each optional square 110b1 is determined by the layout or distribution of the associated first-party enabled square 110a1 and associated second-party enabled square 110a2 on the board 100 in the current game step. More specifically, for each optional square 110b1, there exists at least one associated first-party enabled square 110a1 and at least one associated second-party enabled square 110a2 associated with that optional square 110b1. According to some embodiments, the optional square 110b1 varies in different game steps within a game phase. According to some embodiments, in a game step of a game phase, the move position selection unit 600 is configured to perform a selection operation that can only "access" the optional squares 110b1 in the non-enabled squares 110b, and cannot "access" the non-optional squares 110b2 in the enabled squares 110a and non-enabled squares 110b that are in an enabled state. More specifically, enabled squares 110a and unselectable squares 110b2 are not selected by the move position selection unit 600. Therefore, the operation of the move position selection unit 600 avoids all enabled squares 110a and all unselectable squares 110b2, and only traverses at least one of the selectable squares 110b1 to select the desired square. This further simplifies the user's selection operation, eliminates unnecessary operations, enhances the user's focus and interest, and helps to speed up the game progress.

[0197] According to some embodiments, the checkerboard display unit 310 is also configured to provide optional indicator information (such as...) in the illuminated state. Figure 9 , 14-18 (marked with ③ in light blue) indicates the corresponding square; more specifically, the corresponding inactive square is the optional square 110b1. The optional indication information differs from the first and second enabled indication information. The optional indication information allows users to quickly identify squares in the current game that can be placed or transformed, assisting the player in quickly locking in possible placement positions, reducing the game's difficulty and entry barrier, accelerating the game process, and enhancing human-computer interaction and game enjoyment.

[0198] According to some embodiments, the control module 400 is configured to control the display module 300 in response to the input detection unit determining that the selection operation of the move position selection unit 600 satisfies the above-mentioned conversion conditions, so that the grid display unit 310 corresponding to the selected grid changes from displaying optional indication information to displaying one of the first activation indication information and the second activation indication information to indicate the conversion from the selected grid to the currently activated grid. This configuration can present the dynamic process of the conversion from the selected grid to the currently activated grid through the display module 300, thereby allowing the user to easily confirm which grid has been converted, enhancing human-computer interaction, and more specifically enhancing the user-friendliness and interactivity of the chess device 10, attracting user attention and increasing user interest. According to some embodiments, the control module 400 is further configured to control the display module 300 in response to the input detection unit determining that the selection operation of the move position selection unit 600 satisfies the above-mentioned conversion conditions, so that the grid display unit 310 corresponding to the other optional grids 110b1 besides the selected grid changes from displaying optional indication information to an off state or a reduced brightness state. This configuration prevents irrelevant optional squares 110b1 from causing any visual interference to the transformation process of the selected square and the flipping process of the at least one associated opponent-enabled square, thereby allowing the user's line of sight and attention to be locked on the relevant transformation and flipping squares, quickly judge the current changes in the game, and also allows for reduced power consumption.

[0199] According to some embodiments, the optional squares 110b1 include the selected square 110c and the remaining optional squares 110b1 other than the selected square 110c. According to some embodiments, the selection sensing signal generated by the move position selection unit 600 during the selection operation is communicated to the control module 400, thereby allowing the control module 400 to determine which square the move position selection unit 600 is currently operating on, i.e., to determine the currently selected square 110c. According to some embodiments, the optional indication information includes different first optional indication information (such as...). Figure 9-10 (marked with ④ in dark blue in sections 14-18) and second optional information (such as...) Figure 9-10(In sections 14-18, marked with a light blue ③), the optional indicator information is used to indicate the selected square 110c, and the second optional indicator information is used to indicate the remaining optional squares 110b1. This configuration allows users to easily and intuitively distinguish which optional square 110b1 has been selected by the move selection unit 600 and the positions of the remaining optional squares 110b1 on the chessboard 100, thereby quickly making a decision on whether to place a move, further enhancing human-computer interaction and attracting user attention.

[0200] According to some embodiments, the control module 400 can be configured to communicate with the move position selection unit 600, so as to control the display module 300 in response to the selection operation of the move position selection unit 600, so that the move display unit 310 corresponding to the selected move 110c switches from displaying second optional indication information to displaying first optional indication information, thereby intuitively indicating that the selectable move 110b1 currently located by the move position selection unit 600 is the currently selected move 110c. According to some embodiments, the control module 400 can also be configured to control the move display unit 310 corresponding to the previously selected move 110c to switch from displaying first optional indication information to displaying second optional indication information in response to the operation of the move position selection unit 600, so as to indicate that the previously selected move 110c is no longer the selected move 110c after further operation of the move position selection unit 600, but belongs to other optional moves 110b1. According to some embodiments, in a game step, the move position selection unit 600 can be configured to locate a corresponding one of the selectable squares 110b1 as the currently selected square 110c for each selection operation. For example, if the move position selection unit 600 performs two selection operations, namely a first selection operation and a second selection operation, the selectable square selected in the first selection operation is called the previously selected square 110c, and the selectable square selected in the second selection operation is called the currently selected square 110c. After the first operation of the move position selection unit 600 is completed, the square display unit 310 corresponding to the previously selected square 110c displays first selectable indication information; and With the second operation of the move selection unit 600, the move display unit 310 corresponding to the previously selected move 110c changes from displaying the first optional indication information to displaying the second optional indication information to indicate that the previously selected move 110c becomes "another optional move 110b1", that is, it is no longer the selected move 110c. Meanwhile, the move display unit 310 corresponding to the currently selected move 110c changes from displaying the second optional indication information to displaying the first optional indication information to indicate that it becomes the currently selected move 110c.

[0201] According to some embodiments, the chess device 10 can be configured such that, in a game step, there are multiple selectable squares 110b1, which may have a first order, and the move position selection unit 600 can be operated to select according to the first order. According to a further embodiment, the chess device 10 can also be configured such that, in a game step, the move position selection unit 600 can also be operated to select according to a second order, which is the inversion of the first order. For example, if there are five selectable squares ABCDE in a game step, the move position selection unit 600 can be operated to select according to the first order ABCDE; further, the move position selection unit 600 can also be operated to select according to the second order EDCBA. More specifically, the move position selection unit 600 is configured to be operable for both forward and reverse selection operations, and this forward and reverse selection operation can be switched at any time. For example, when the move selection unit 600 performs a selection operation according to the first sort and selects the optional square C as the current selected square 110c after traversing optional squares A and B, the move selection unit can then continue to perform a selection operation according to the first sort to select optional square D, or it can reverse the selection operation according to the second sort to select optional square B. According to some embodiments, the control module 400 is configured to sort all existing optional squares 110b1 at the beginning of each game step and associate the operation of the move selection unit 600 with this sorting, so that the operation of the move selection unit 600 follows this sorting or a reverse of this sorting for the selection operation.

[0202] According to some embodiments, the control module 400 is configured to control the display module 300 in response to the input detection unit determining that the selection operation of the move position selection unit 600 meets the conversion conditions, so that the move display unit 310 corresponding to the selected move square changes from displaying a first optional indication information to displaying one of a first activation indication information and a second activation indication information to indicate the conversion from the selected move square to the currently activated move square. This configuration can present the dynamic process of the conversion from the selected move square to the currently activated move square through the display module 300, thereby allowing the user to easily confirm which move square has been converted, enhancing human-computer interaction, and more specifically enhancing the user-friendliness and interactivity of the chess device 10, attracting user attention and increasing user interest. According to some embodiments, the control module 400 is also configured to control the display module 300 in response to the input detection unit determining that the selection operation of the move position selection unit 600 meets the conversion conditions, so that the move display unit 310 corresponding to the other optional move squares 110b1 changes from displaying a second optional indication information to an off state or a reduced brightness state. This configuration prevents irrelevant optional squares 110b1 from causing any visual interference to the transformation process of the selected square and the flipping process of the at least one associated opponent-enabled square, thereby allowing the user's line of sight and attention to be locked on the relevant transformation and flipping squares, quickly judge the current changes in the game, and also allows for reduced power consumption.

[0203] According to some embodiments, the display module 300 is configured to keep the display units 310 corresponding to the non-selectable squares 110b2 (excluding the selectable squares 110b1) in the non-enabled squares 110b in a turned-off state during game steps. This avoids any visual interference from the non-selectable squares 110b2 to other squares and also helps to save power.

[0204] The third variant of chess equipment 10

[0205] According to some embodiments, such as Figure 1-4Figures 8-18 and 29 schematically illustrate that the conversion module may include a second move position confirmation unit 700 configured to convert a selected square into a currently active square. More specifically, the second move position confirmation unit 700 is configured to be operable to convert a selected square into a currently active square. According to some embodiments, a control module 400 is configured to be communicatively connected to the second move position confirmation unit 700. According to some embodiments, the chess device 10 is configured to convert the at least one associated opponent active square into a currently active square when the second move position confirmation unit 700 is operated. According to some embodiments, the control module 400 may be configured to control the display module 300 in response to the operation of the second move position confirmation unit 700, such that the square display unit 310 corresponding to the selected square switches to displaying one of a first activation indication information and a second activation indication information to indicate the conversion of the selected square to a currently active square. According to a further or alternative embodiment, the control module 400 may be configured to respond to the operation of the second move position confirmation unit 700 to control the display module 300, such that the move display unit 310 corresponding to the at least one associated opponent's activated move is switched from displaying one of the first activation indication information and the second activation indication information to displaying one of the first activation indication information and the second activation indication information to indicate the conversion of the at least one associated opponent's activated move to the current player's activated move. This ensures human-computer interaction and game fun, and realizes the "flipping" action of the opponent's move after the current player "places a move", enhancing the game experience.

[0206] According to some embodiments, the second move position confirmation unit 700 is configured to generate a confirmation sensing signal upon operation, and the control module 400 is configured to control the display module 300 to perform the aforementioned operation in response to the generation or receipt of the confirmation sensing signal. According to some embodiments, the chess device 10 may include a single second move position confirmation unit 700 for user operation. According to some embodiments, the single second move position confirmation unit 700 is configured for operation by either of the two players. According to some embodiments, the chess device 10 may include two second move position confirmation units 700 for operation by a corresponding player in each game. According to some embodiments, the second move position confirmation unit 700 may include a touch control or button, etc., electrically connected to the control module 400.

[0207] According to some embodiments, such as Figure 1-4Figure 10-31 schematically illustrates that the conversion module can be configured to include a move position selection unit 600, which is configured to operate to select one of the inactive squares 110b. This operation of the move position selection unit 600 can be referred to as a "selection operation". According to some embodiments, an inactive square 110b selected by the move position selection unit 600 is collectively referred to as "selected square 110c" in this third embodiment. More specifically, the inactive square 110b corresponding to each selection operation of the move position selection unit 600 is called the selected square 110c. More specifically, the selected square 110c that is converted into a currently active square by the second move position confirmation unit 700 is the aforementioned selected square. According to some embodiments, in the game steps of the game phase, the move position selection unit 600 is configured to only "access" or select inactive squares 110b when performing a selection operation, and cannot "access" or select active squares 110a that are in an active state. More specifically, the selected square 110a is not an option for the placement selection unit 600. Therefore, the operation of the placement selection unit 600 will avoid all selected squares 110a and only select one square from the range of non-selected squares 110b. This allows the user's selection operation via the placement selection unit 600 to be more targeted, eliminating unnecessary steps, speeding up the game, and preventing the user from becoming annoyed by cumbersome selection operations.

[0208] It should be noted that the main difference between this third variant and the second variant is that, in this third variant, the conversion module does not perform the conversion of the selected square and the at least one associated opponent-enabled square to the current-enabled square based on the selection operation of the move position selection unit 600 satisfying the conversion conditions described in the second variant. Instead, this conversion is achieved through the operation of the second move position confirmation unit 700.

[0209] According to some embodiments, such as Figure 9-18 As schematically shown, the checkerboard display unit 310 can be configured to provide selection indication information (e.g., using...) when the checkerboard is lit up. Figure 9 , 14-17 is marked with a dark blue ④, allowing the user to easily observe which square 110c is currently selected. The selection indication information is different from both the first and second activation indication information. According to some embodiments, "selected square 110c" is defined as the square that the move position selection unit 600 "accesses," "traverses," or "locks" at the current moment. According to some embodiments, the control module 400 can be communicatively connected to the move position selection unit 600. More specifically, the move position selection unit 600 generates a selection sensing signal during operation, which is communicated to the control module 400, so that the control module 400 can determine which square the move position selection unit 600 is currently operating on, i.e., determine the current selected square 110c. According to some embodiments, the control module 400 can be configured to control the display module 300 in response to the operation of the move position selection unit 600, so that the square display unit 310 corresponding to the selected square 110c displays the selection indication information. For example, the chess square display unit 310 corresponding to the selected chess square 110c can be configured to switch from an off state to displaying selection indication information. According to a further embodiment, the control module 400 can be configured to control the display module 300, and more specifically, control the chess square display unit 310 corresponding to the selected chess square to switch from displaying selection indication information to displaying one of a first activation indication and a second activation indication, in response to the operation of the second move position confirmation unit 700, to indicate the transition from the selected chess square to the currently activated chess square. This configuration allows the display module 300 to present the dynamic process of the transition from the selected chess square to the currently activated chess square, thereby making it easy for the user to confirm which chess square has been transformed, enhancing human-computer interaction, and more specifically, enhancing the user-friendliness and interactivity of the chess device 10, attracting user attention and increasing user interest.

[0210] According to some embodiments, such as Figure 9-10Figures 14-18 schematically illustrate that an inactive square 110b may include an optional square 110b1. More specifically, in the current game step of a game phase, an inactive square 110b may include optional squares 110b1 and unselectable squares 110b2. Optional squares 110b1 are squares that can be selected for transformation in the current game step, i.e., squares that can be selected in the current move to become the current player's active square. More specifically, unselectable squares 110b2 are squares that cannot be selected in the current game step. More specifically, the selected square 110c described above is one of the optional squares 110b1. According to some embodiments, each optional square 110b1 is determined by the layout or distribution of the associated first-player active square 110a1 and associated second-player active square 110a2 on the board 100 in the current game step. More specifically, for each optional square 110b1, there exists at least one associated first-party enabled square 110a1 and at least one associated second-party enabled square 110a2 associated with that optional square 110b1. According to some embodiments, the optional square 110b1 varies in different game steps within a game phase. According to some embodiments, in game steps of a game phase, the second move position confirmation unit 700, as described in the first variant, is configured to be effective only when operating in relation to the optional square 110b1; more specifically, only the second move position confirmation unit 700 corresponding to the optional square 110b1 is operable. According to some embodiments, in game steps of a game phase, the move position selection unit 600, as described in the second and third variants, is configured to perform a selection operation that can only "access" the optional square 110b1 in the non-enabled square 110b, and cannot "access" the enabled squares in the enabled state and the non-optional squares 110b2 in the non-enabled square 110b. More specifically, enabled squares 110a and unselectable squares 110b2 are not selected by the move position selection unit 600. Therefore, the operation of the move position selection unit 600 avoids all enabled squares 110a and all unselectable squares 110b2, and only traverses at least one of the selectable squares 110b1 to select the desired square. This further simplifies the user's selection operation, eliminates unnecessary operations, enhances the user's focus and interest, and helps to speed up the game progress.

[0211] According to some embodiments, the checkerboard display unit 310 is also configured to provide optional indicator information (such as...) in the illuminated state. Figure 9 , 14-18 (marked with a light blue ③) indicates the corresponding square. More specifically, the corresponding inactive square 110b is an optional square 110b1. The optional indication information is different from the first and second enabled indication information. The optional indication information allows users to quickly identify the squares in the current game that can be placed or transformed, helping the player to quickly lock in the possible placement positions, reducing the game difficulty and entry threshold, accelerating the game process, and enhancing human-computer interaction and game fun.

[0212] According to some embodiments, the control module 400 is configured to control the display module 300 in response to the operation of the second move position confirmation unit 700, so that the grid display unit 310 corresponding to the selected grid changes from displaying optional indication information to displaying one of the first activation indication information and the second activation indication information to indicate the transition from the selected grid to the currently activated grid. This configuration can present the dynamic process of the transition from the selected grid to the currently activated grid via the display module 300, thereby making it easy for the user to confirm which grid has been transformed, enhancing human-computer interaction, and more specifically enhancing the user-friendliness and interactivity of the chess device 10, attracting user attention and increasing user interest. According to some embodiments, the control module 400 is further configured to control the display module 300 in response to the operation of the second move position confirmation unit 700, so that the grid display unit 310 corresponding to the other optional grids 110b1 besides the selected grid changes from displaying optional indication information to an off state (e.g., Figure 13 (Illustrated schematically) or in a dimmed state. This configuration prevents irrelevant optional squares 110b1 from causing any visual interference to the transformation process of the selected square and the flipping process of the at least one associated opponent-enabled square, thereby allowing the user's line of sight and attention to be locked on the relevant transformation and flipping squares, quickly judge the current game situation, and also allow for reduced power consumption.

[0213] According to some embodiments, the optional squares 110b1 include the selected square 110c and the remaining optional squares 110b1 other than the selected square 110c. According to some embodiments, the selection sensing signal generated by the move position selection unit 600 during the selection operation is communicated to the control module 400, thereby allowing the control module 400 to determine which square the move position selection unit 600 is currently operating on, i.e., to determine the currently selected square 110c. According to some embodiments, the optional indication information includes different first optional indication information (such as...). Figure 9-10 (marked with ④ in dark blue in sections 14-18) and second optional information (such as...) Figure 9-10(In sections 14-18, marked with a light blue ③), the first optional indicator information is used to indicate the selected square 110c, and the second optional indicator information is used to indicate the remaining optional squares 110b1. This configuration allows users to easily and intuitively distinguish which optional square 110b1 has been selected by the move selection unit 600 and the location of the remaining optional squares 110b1 on the chessboard 100, thereby quickly making a decision on whether to place a move, further enhancing human-computer interaction and attracting user attention.

[0214] According to some embodiments, the control module 400 can be configured to communicate with the move position selection unit 600, so as to control the display module 300 in response to the selection operation of the move position selection unit 600, so that the move display unit 310 corresponding to the selected move 110c switches from displaying second optional indication information to displaying first optional indication information, thereby intuitively indicating that the selectable move 110b1 currently located by the move position selection unit 600 is the currently selected move 110c. According to some embodiments, the control module 400 can also be configured to control the move display unit 310 corresponding to the previously selected move 110c to switch from displaying first optional indication information to displaying second optional indication information in response to the operation of the move position selection unit 600, so as to indicate that the previously selected move 110c is no longer the selected move 110c after further operation of the move position selection unit 600, but belongs to other optional moves 110b1. According to some embodiments, in a game step, the move position selection unit 600 can be configured to locate a corresponding one of the selectable squares 110b1 as the currently selected square 110c for each selection operation. For example, if the move position selection unit 600 performs two selection operations, namely a first selection operation and a second selection operation, the selectable square 110b1 selected in the first selection operation of the move position selection unit 600 is called the previously selected square 110c, and the selectable square 110b1 selected in the second selection operation of the move position selection unit 600 is called the currently selected square 110c. Then, after the first operation of the move position selection unit 600 is completed, the square display unit 310 corresponding to the previously selected square 110c displays the first selectable square. The information is displayed; however, with the second operation of the move position selection unit 600, the move display unit 310 corresponding to the previously selected move 110c changes from displaying the first optional indication information to displaying the second optional indication information to indicate that the previously selected move 110c becomes "another optional move 110b1", that is, no longer the selected move 110c. Meanwhile, the move display unit 310 corresponding to the currently selected move 110c changes from displaying the second optional indication information to displaying the first optional indication information to indicate that it becomes the currently selected move 110c. Alternatively, the move position selection unit 600 can be configured to lock one of the optional moves 110b1 as the currently selected move after multiple operations. Alternatively, the move position selection unit 600 can be configured to lock the optional move 110b1 associated with the operation as the currently selected move only after a given time period has elapsed following the operation. This predetermined time period is, for example, 2-8 seconds.

[0215] According to some embodiments, the chess device 10 can be configured such that, in a game step, there are multiple selectable squares 110b1, which may have a first order, and the move position selection unit 600 can be operated to select according to the first order. According to a further embodiment, the chess device 10 can also be configured such that, in a game step, the move position selection unit 600 can also be operated to select according to a second order, which is the inversion of the first order. For example, if there are five selectable squares ABCDE in a game step, the move position selection unit 600 can be operated to select according to the first order ABCDE; further, the move position selection unit 600 can also be operated to select according to the second order EDCBA. More specifically, the move position selection unit 600 is configured to be operable for both forward and reverse selection operations, and this forward and reverse selection operation can be switched at any time. For example, when the move selection unit 600 performs a selection operation according to the first sort and selects the optional square C as the current selected square 110c after traversing optional squares A and B, the move selection unit can then continue to perform a selection operation according to the first sort to select optional square D, or it can reverse the selection operation according to the second sort to select optional square B. According to some embodiments, the control module 400 is configured to sort all existing optional squares 110b1 at the beginning of each game step and associate the operation of the move selection unit 600 with this sorting, so that the operation of the move selection unit 600 follows this sorting or a reverse of this sorting for the selection operation.

[0216] According to some embodiments, the control module 400 is configured to control the display module 300 in response to the operation of the second move position confirmation unit 700, such that the move display unit 310 corresponding to the selected move changes from displaying a first optional indication information to displaying one of a first activation indication information and a second activation indication information to indicate the transition from the selected move to the currently activated move (from...). Figure 9 , 10 arrive Figure 11 This transformation is illustrated exemplarily. This configuration enables the display module 300 to present the dynamic process of the transformation from a selected square to the currently enabled square, allowing the user to easily identify which square has been transformed, enhancing human-computer interaction, and more specifically, enhancing the user-friendliness and interactivity of the chess device 10, attracting user attention and increasing user interest. According to some embodiments, the control module 400 is also configured to control the display module 300 in response to the operation of the second move position confirmation unit 700, so that the square display unit 310 corresponding to the other optional squares 110b1 changes from displaying the second optional indication information to an off state or a reduced brightness state (from...). Figure 9 , 10 arrive Figure 13 (This transformation is illustrated exemplarily). This configuration prevents irrelevant optional squares 110b1 from causing any visual interference to the transformation process of the selected square and the flipping process of the at least one associated opponent-enabled square, thereby allowing the user's line of sight and attention to be locked on the relevant transformed and flipped squares, quickly judge the current board position changes, and also allows for reduced power consumption.

[0217] According to some embodiments, the display module 300 is configured to keep the display units 310 corresponding to the non-selectable squares 110b2 (excluding the selectable squares 110b1) in the non-enabled squares 110b in a turned-off state during game steps. This avoids any visual interference from the non-selectable squares 110b2 to other squares and also helps to save power.

[0218] According to some embodiments, the move selection unit and the move confirmation unit are configured as an integrated unit. Exemplarily, the integrated unit may integrate a unit that can be both rotated and pressed, more specifically, it may integrate a knob and a button. The knob, for example, corresponds to the move selection unit and is configured to perform a selection operation when rotated, and the button, for example, corresponds to the second move confirmation unit and is configured to perform a conversion from the selected square to the current player's enabled square and / or at least one associated opponent's enabled square to the current player's enabled square when pressed. According to some embodiments, the chess device 10 may include a single integrated unit operated by both players. According to some embodiments, the chess device 10 may include two integrated units, each operated by one of the players.

[0219] General configuration of chess and card game device 10

[0220] In all variations of this application, according to some embodiments, the chess device 10, and more specifically the control module 400, is configured to automatically switch between successive game steps during the game. More specifically, the control module 400 is configured to, immediately or after a period of time, cause the chess device 10 to proceed to the next game step after the selected square and its associated opponent-enabled square are converted to the current player's enabled square in the current game step. In some embodiments, the control module 400 is configured to control the display module 300 to display the optional square 110b1 in the next game step after proceeding to the next game step. For example, it can control the square display unit 310 corresponding to the optional square 110b1 in the next game step to display optional indication information to indicate the optional square 110b1. In some embodiments, the chess device 10 is configured to automatically display all available squares 110b1 at the start of each game step, and automatically select one available square 110b1 as the currently selected square 110c. More specifically, the currently selected square 110c and the remaining available squares 110b1 are displayed by the corresponding square display unit 310 displaying first optional indication information and second optional indication information, respectively. According to some embodiments, the currently selected square 110c automatically selected at the start of each game step is the first available square 110b1 in the first sorting described above, for example, available square A.

[0221] According to some embodiments, such as Figure 15-17As shown, the chess device 10 is configured such that, at the start of a game, or more specifically, upon power-on, the chessboard includes a certain number of first-player enabled chessboards 110a1 and second-player enabled chessboards 110a2. According to some embodiments, the control module 400 is configured to control the display module 300 to display first-player enabled indication information on the chessboard display unit 310 corresponding to the first-player enabled chessboard 110a1, and second-player enabled indication information on the chessboard display unit 310 corresponding to the second-player enabled chessboard 110a2 at the start of a game. According to one embodiment, the chess device 10 is configured such that the number of first-player enabled chessboards 110a1 and the number of second-player enabled chessboards 110a2 included at the start of a game are equal. Alternatively, the chess device 10 may be configured such that the number of first-player enabled chessboards 110a1 and the number of second-player enabled chessboards 110a2 included at the start of a game are not equal. According to some embodiments, the chess device 10 is configured such that, at the start of a game, the chessboard includes two first-player enabled chessboards 110a1 and two second-player enabled chessboards 110a2. Exemplarily, the two first-player enabled chessboards 110a1 and the two second-player enabled chessboards 110a2 are adjacent to each other. Exemplarily, the two first-player enabled chessboards 110a1 and the two second-player enabled chessboards 110a2 are located in the central area of ​​the chessboard 100. According to one embodiment, the two first-player enabled chessboards 110a1 and the two second-player enabled chessboards 110a2 are arranged in a rectangular array, with the two first-player enabled chessboards 110a1 forming a first diagonal of the rectangular array and the two second-player enabled chessboards 110a2 forming a second diagonal of the rectangular array.

[0222] In some embodiments, such as Figure 2-7 As shown in Figures 9, 11-17, the plurality of squares 110 formed on the chessboard 100 are arranged in an array. In one embodiment, the plurality of squares on the chessboard 100 are arranged in a rectangular array, more specifically in multiple rows and / or multiple columns. According to an exemplary embodiment, the chessboard 100 is an 8×8 rectangular array. In one embodiment, the plurality of squares on the chessboard 100 are arranged in a square array; more specifically, the plurality of squares are arranged in multiple rows and multiple columns. According to some embodiments, the chessboard 100 has a regular overall shape. According to some embodiments, the chessboard 100 has a circular, elliptical, rectangular, or equilateral polygonal (e.g., an even number of squares) shape. According to some embodiments, the entire chess device 10 may be cylindrical, such as cylindrical or prismatic. According to an alternative embodiment, at least a portion of the chess device 10 may be cylindrical, such as cylindrical or prismatic.

[0223] According to some embodiments, exemplarily, such as Figure 1 , 3-4, 25, 29-31 The chess-playing device 10 may include a cover plate 30, and a chessboard 100 may be disposed on the cover plate 30 or constitute at least a part of the cover plate 30. More specifically, the second move position confirmation unit 700 or the integrated unit or the move position selection unit 600 according to the third variant may be disposed on the cover plate 30 and positioned close to the chessboard 100. Exemplarily, the second move position confirmation unit 700 is configured as a button or touch control. Exemplarily, the integrated unit is configured to integrate a knob portion and a button portion. Exemplarily, the move position selection unit 600 is configured as a button or touch control.

[0224] According to some embodiments, the chess-playing device 10 is configured to include a single-player game mode and a two-player game mode. More specifically, such as Figure 1-3 As schematically shown, the chessboard device 10 may include a mode switching component 40 configured to switch between a single-player game mode and a two-player game mode. Exemplarily, the mode switching component 40 may be in the form of a slider that can slide between different positions, or a lever or knob that can rotate between different angle positions; exemplaryly, the mode switching component 40 may be in the form of a button or key; exemplaryly, the mode switching component 40 may be in the form of a touchscreen. According to some embodiments, a control module 400 is configured to communicatively connect to the mode switching component 40 to switch the chessboard 100 device to the corresponding game mode in response to operation of the mode switching component 40.

[0225] According to some embodiments, the first party uses a chessboard 110a1 to represent the first player or the first side in the game of the chess device 10, and the second party uses a chessboard 110a2 to represent the second player or the second side in the game of the chess device 10.

[0226] According to some embodiments, such as Figure 9 , 11 -17 schematically shows that the chess device 10 may define a first occupying point 11 and a second occupying point 12 opposite to each other. The first occupying point 11 is for one of the two players in the chess device 10, and more specifically, the player may be located on the side of the first occupying point 11 of the chess device 10. The second occupying point 12 is for the other player in the chess device 10, and more specifically, the other player may be located on the side of the second occupying point 12 of the chess device 10.

[0227] According to some embodiments, such as Figure 9 , 11-17 schematically illustrates that the chessboard 100 may include a grid area 100a, which is an area of ​​the chessboard 100 capable of forming the plurality of grids 110. The grid area 100a may have a center point.

[0228] According to some embodiments, such as Figure 9 , 11 -17 schematically illustrates that the chessboard area 100a has a first axis X1 passing through its center point, a first endpoint of the first axis X1 intersecting the periphery of the chessboard area 100a defining a first occupant point 11, and a second endpoint of the first axis X1 intersecting the periphery of the chessboard area 100a defining a second occupant point 12. According to some embodiments, in the single-player game mode of the chessboard device 10, the first occupant point 11 can be used for the first player, and the second occupant point 12 can be used for the second player; exemplarily, the first player is a user (in the sense of this document, a user refers to an actual entity, which can be a human or a robot) among the two players in the human-computer mode, and the chessboard device 10 itself or its control module 400, as the second player among the two players, can be considered to be "virtually" located on the side of the second occupant point 12; and vice versa. According to some embodiments, the first player can be the first user among the two players in the two-player game mode, and the second player can be the other user among the two players in the two-player game mode.

[0229] According to some embodiments (not shown), the chess device 10 may include two move selection units 600 according to a second variation, which are respectively positioned near the first position 11 and the second position 12, for use by corresponding parties in a two-player game mode. According to some embodiments, the chess device 10 may include two second move confirmation units 700 or integrated units according to a third variation, which are respectively positioned near the first position 11 and the second position 12, for use by corresponding parties in a two-player game mode.

[0230] According to an alternative embodiment, the chess device 10 includes a single second move position confirmation unit 700 according to a third variant, an integrated unit according to a third variant, or a single move position selection unit 600 according to a second variant, positioned near the first occupant point 11, more specifically the occupant point for the user. Exemplarily, the single second move position confirmation unit 700, the single integrated unit, or the single move position selection unit 600 is positioned outside the chess square area 100a and near the first occupant point 11, for example, in an area of ​​the chessboard 100 other than the chess square area 100a, or on a cover plate 30, the chessboard 100 forming at least a portion of the cover plate 30, which may be an endplate of the chess device 10. This arrangement facilitates user operation of the second move position confirmation unit 700, the integrated unit, or the move position selection unit 600, and is ergonomically sound. By way of example and not exclusively, if the checkerboard region 100a is a square, the first occupant 11 and the second occupant 12 may optionally be defined on two opposite sides of the checkerboard region 100a; if the checkerboard region 100a is circular, the first occupant 11 and the second occupant 12 may be radially opposite each other.

[0231] In some embodiments, such as Figure 9 , 11-17 schematically illustrates that the chess-playing device 10 may also be configured to include a third occupant point 13 and a fourth occupant point 14 disposed opposite to each other, each of the third occupant point 13 and the fourth occupant point 14 being different from the first occupant point 11 and the second occupant point 12. In some embodiments, the third occupant point 13 may be circumferentially displaced relative to the first occupant point 11 by an offset angle of +90° or -90°, and the fourth occupant point 14 may correspondingly be circumferentially displaced relative to the second occupant point 12 by an offset angle of +90° or -90°. In some embodiments, the chessboard area 100a has a second axis X2 perpendicular to the first axis X1 and passing through its center point, the first endpoint of the second axis X2 intersecting the periphery of the chessboard area 100a defining the third occupant point 13, and the second endpoint of the second axis X2 intersecting the periphery of the chessboard area 100a defining the fourth occupant point 14. By way of example, and not exclusively, if the chessboard area 100a is a square, then the third occupant point 13 and the fourth occupant point 14 can be defined on two opposite sides of the chessboard area 100a; if the chessboard area 100a is circular, then the third occupant point 13 and the fourth occupant point 14 can be radially opposite each other. More specifically, in the two-player game mode of the chessboard device 10, the first user, as the first player in the game, can be located on the side of the third occupant point 13, while the second user, as the second player in the game, can be located on the side of the fourth occupant point 14. This is particularly advantageous in embodiments where the chess device 10 includes only a single second move position confirmation unit 700, a single integrated unit, or a single move position selection unit 600 located near the first occupancy point 11. This ensures that in a two-player game mode, both the first and second players can easily access and operate the single second move position confirmation unit 700, the single integrated unit, or the single move position selection unit 600, and that neither player's move can obstruct the other player's view of the chess square area 100a. This also helps reduce the number of components in the chess device 10, resulting in a more compact overall structure and improved cost-effectiveness.

[0232] According to some embodiments, the checkerboard area 100a is one of the following shapes: circular; rectangular; elliptical; equilateral polygon, where "polygon" means an even number of sides. According to some examples, the checkerboard 100 or the cover plate 30 is one of the following shapes: circular; rectangular; elliptical; equilateral polygon; more specifically, where "polygon" means an even number of sides.

[0233] According to one embodiment, the chess-playing device 10 includes a circular cover plate 30, and the chess square area 100a is rectangular, more specifically square, and the plurality of chess squares 110 are exemplarily distributed in a rectangular array; optionally, the four corners of the chess square area 100a lie on the circular outer contour of the circular cover plate 30. Optionally, the chessboard 100 forms at least a portion of the circular cover plate 30.

[0234] In some embodiments, such as Figure 15 and 16 As shown, where Figure 15 The diagram illustrates the power-on state in the human-computer chess game mode. Figure 16 The diagram schematically illustrates the power-on state in a two-player game mode. The chess device 10 is further configured such that the power-on state of the chess device 10, i.e. the state at the start of the game, shifts angularly in accordance with the angle shift of the occupant positions of the two players as the game mode is switched. This ensures that regardless of the game mode, the user's ergonomics, ease of observation of the game board, and ease of operation are met. It also allows players to intuitively perceive the game mode of the chess device 10 without having to observe the position of the mode switching component 40 to know the current game mode. In some embodiments, the state at the start of the game may include the layout or positioning of the first player's activated square 110a1 and the second player's activated square 110a2 on the board 100, and therefore correspondingly include the state of the relevant square display unit 310; in further embodiments, it may also include the display of optional square 110b1 or the display of optional indication information of the relevant square display unit 310, more specifically including the display of the currently selected square 110c (i.e., the display of the first optional indication information of the relevant square display unit 310) and the display of the remaining optional squares 110b1 (i.e., the display of the second optional indication information of the relevant square display unit 310); in further embodiments, it may also include the display of the initial state of the indicator light assembly 800, which serves as an advantage / disadvantage indication module, as described below.

[0235] Conversion or flipping process

[0236] According to some embodiments, such as Figure 11-12As shown, the control module 400 is configured to control the display module 300 so that during the process of converting the selected square and the at least one associated opponent-enabled square to the current-enabled square, only the square display unit 310 corresponding to the selected square, the at least one associated opponent-enabled square, and the at least one associated current-enabled square is lit up, wherein the associated current-enabled square is the current-enabled square associated with the selected square. This process of "converting the selected square and the at least one associated opponent-enabled square to the current-enabled square" can be called a "flipping process." According to some embodiments of the first and second variations described above, the process from the operation of the placement confirmation units 500 and 700 until the selected square and the at least one associated opponent-enabled square complete the conversion to the current-enabled square is a flipping process. According to some embodiments of the second variation described above, the process from the input detection module confirming that the selection operation of the placement selection unit 600 meets the conversion conditions until the selected square and the at least one associated opponent-enabled square complete the conversion to the current-enabled square is a flipping process. More specifically, the control module 400 is configured to control the display module 300 so that all checkerboard squares unrelated to the flipping process are turned off during the flipping process.

[0237] According to an alternative embodiment (not shown), the control module 400 is configured to control the display module 300 such that, during the flipping process, the grid display units 310 corresponding to the selected grid, the at least one associated current enabled grid, and the at least one associated opposing enabled grid are in an enhanced illumination state. "Enhanced illumination state" refers to an enhanced illumination or display intensity compared to the normal illumination state, i.e., the illumination state not during the flipping process, to highlight the grid involved in the flipping process. Additionally or alternatively, during the flipping process, the grid display units 310 corresponding to the remaining illuminated grids (i.e., grids unrelated to the flipping process) are in a reduced brightness state. More specifically, the remaining illuminated grids may include other enabled grids 110a and / or other optional grids 110b1. "Reduced illumination state" refers to a less illuminated or reduced brightness state compared to the normal illumination state, i.e., the illumination state not during the flipping process, so that grids not involved in the flipping process do not attract the user's attention. More specifically, by enhancing the brightness of the display units 310 corresponding to the selected square, at least one associated opponent-enabled square, and at least one associated current-enabled square, even when they are in a brightness enhancement state, and / or by reducing the display brightness of other enabled squares and / or optional squares 110b1 other than the aforementioned selected square, at least one associated opponent-enabled square, and at least one associated current-enabled square, even when they are in a brightness reduction state.

[0238] These configurations help highlight the dynamic flipping process, making it easy for users to visually identify which squares have been "flipped." This reduces or avoids visual interference from irrelevant enabled and optional squares 110b1 during the flipping process, enhancing the gaming experience and saving power consumption, thus extending game time.

[0239] Based on some examples, such as Figure 11-12 As shown, the control module 400 is configured to control the display module 300 so that during the flipping process, the display units 310 corresponding to the remaining active squares in the first active square 110a1 and the second active square 110a2, excluding the associated opponent active square and the associated current active square, are temporarily turned off. Figure 11-12 The screen will either be in an off state or a dimmed state (not shown), and after the flipping process is complete, it will return to its original on state and lit state from the off state or dimmed state. Figure 13 According to some embodiments, the control module 400 is configured to control the display module 300 such that, during the flipping process, the display unit 310 corresponding to the remaining optional squares 110b1 in this game step is turned off. Figure 13 (or its brightness is reduced, and it does not return to its original state after the flipping process is completed.)

[0240] According to some embodiments, as described above, each optional square 110b1 is determined by the layout or distribution on the chessboard 100 of the associated first-party enabled square 110a1 and the associated second-party enabled square 110a2 in the current game move. According to some embodiments, such as Figure 9 and 11As shown in Figure 17, for an optional square 110b1, there may be one or more associated current-side enabled squares. According to some embodiments, the optional square 110b1, one of the associated current-side enabled squares associated with the optional square 110b1, and at least one associated opponent enabled square associated with the optional square 110b1 and the associated current-side enabled square are defined as follows: the at least one associated opponent enabled square is adjacent to each other, and the at least one associated opponent enabled square is located adjacent to the optional square 110b1 and the associated current-side enabled square between the optional square 110b1 and the associated current-side enabled square, and the optional square 110b1, the at least one associated opponent enabled square, and the associated current-side enabled square form a straight line (including at least a portion of a row, at least a portion of a column, and a diagonal line), which may be referred to as a "transformation line" or "flipping line". It should be noted that, as mentioned earlier, for an optional square 110b1, there can be multiple associated currently active squares. Therefore, when operating the move position confirmation units 500 and 700 corresponding to an optional square 110b1, there can be multiple "transform lines" or "flip lines". For example, in Figure 9 , 11 In the example in -12, for the selected square ④, there are three associated current active squares ①, six associated opponent active squares ②, and three transformation lines or flip lines L1, L2, L3.

[0241] According to some embodiments, the chess device 10 is configured to sequentially convert each of the at least one associated opponent-enabled squares into the current-enabled square, for example, starting with an associated opponent-enabled square adjacent to the selected optional square 110b1, i.e., the selected square, and sequentially converting each one into the current-enabled square. More specifically, the control module 400 is configured to control the display module 300 so that the square display units 310 corresponding to the at least one associated opponent-enabled square sequentially convert the displayed indication information to indicate that the at least one associated opponent-enabled square is sequentially converted into the current-enabled square. This configuration can enhance the dynamic display of the flipping process and thus make it easier for the user to observe the flipping process, enhancing human-computer interaction and fun. According to some embodiments, the chess device 10 is configured to convert the selected square into the current-enabled square before the at least one associated opponent-enabled square. More specifically, the chess device 10 can be configured to convert the selected square and the at least one associated opponent-enabled square into the current-enabled square starting from the selected square. More specifically, the control module 400 is configured to control the display module 300 such that the display unit 310 corresponding to the selected square changes the displayed instruction information before the display unit 310 corresponding to at least one associated opponent's enabled square, so as to indicate that the selected square is converted to the current enabled square before at least one associated opponent's enabled square.

[0242] According to some embodiments, the chess device 10 is configured such that at least one associated opponent-enabled square is simultaneously converted to the current player-enabled square. This configuration helps to speed up the game. According to a further embodiment, the control module 400 is configured to control the display module 300 such that the square display unit 310 corresponding to the at least one associated opponent-enabled square simultaneously changes its displayed instruction information to indicate that the at least one associated opponent-enabled square is simultaneously converted to the current player-enabled square. According to some embodiments, the chess device 10 can be configured such that the selected square is converted to the current player-enabled square before the at least one associated opponent-enabled square. More specifically, the control module 400 is configured to control the display module 300 such that the square display unit 310 corresponding to the selected square changes its displayed instruction information before the square display unit 310 corresponding to the at least one associated opponent-enabled square, to indicate that the selected square is converted to the current player-enabled square before the at least one associated opponent-enabled square. This configuration not only indicates the "placement" but also allows for the dynamic display of the "piece" flipping process, which enhances the game experience. According to an alternative embodiment, the chess device 10 can be configured to simultaneously convert the selected square and the at least one associated opponent-enabled square into the current player-enabled square. More specifically, the control module 400 is configured to control the display module 300 such that the square display unit 310 corresponding to the selected square and the square display unit 310 corresponding to the at least one associated opponent-enabled square simultaneously convert their displayed indication information to indicate that the selected square and the at least one associated opponent-enabled square are simultaneously converted into the current player-enabled square. This allows for further acceleration of the game process.

[0243] According to some embodiments, as mentioned above and as Figure 9 , 11As shown in Figure -12, a selected square, at least one associated opponent-enabled square, and at least one associated current-enabled square constitute at least one transition line or flip line. Each transition line or flip line L1, L2, L3 sequentially and adjacently includes: at least one of the selected square, the associated opponent-enabled square, and one of the associated current-enabled squares. According to some embodiments, the chess device 10 is configured such that associated opponent-enabled squares on different transition lines are converted to current-enabled squares in a line-by-line manner. It should be noted that "in a line-by-line manner" means that after one transition line is converted, the next transition line will be converted, and so on, until all transition lines are converted. Further, the control module 400 is configured to control the display module 300 so that the square display unit 310 corresponding to the at least one associated opponent-enabled square changes the displayed indication information line-by-line to indicate that associated opponent-enabled squares on different transition lines are converted to current-enabled squares in a line-by-line manner. This configuration allows for the dynamic display of the flipping process, enabling users to observe the flipping process intuitively, enhancing human-computer interaction and game fun. Specifically, this step-by-step, progressive "flipping" process can enhance the experience of a player expanding their lead or reversing a disadvantageous position.

[0244] According to some embodiments, the chess-playing device 10 is configured such that all associated opponent-enabled squares on the same transition line are simultaneously converted to the current player's enabled square. Further, the control module 400 is configured to control the display module 300 so that the square display units 310 corresponding to the associated opponent-enabled squares on the same transition line simultaneously change their displayed indication information to indicate that the associated opponent-enabled squares on the same transition line are simultaneously converted to the current player's enabled square. According to an alternative embodiment, the chess-playing device 10 can be configured to convert associated opponent-enabled squares on the same transition line one by one to the current player's enabled square, for example, starting from the square display unit 310 corresponding to the selected square and converting them one by one to the current player's enabled square. Further, the control module 400 is configured to control the display module 300 so that the square display units 310 corresponding to the associated opponent-enabled squares on the same transition line sequentially change their displayed indication information to indicate that the associated opponent-enabled squares on the same transition line are sequentially converted to the current player's enabled square. According to some embodiments, the chess-playing device 10 can be configured such that the selected square is converted to the currently active square before all associated opponent-enabled squares. Furthermore, the control module 400 is configured to control the display module 300 such that the square display unit 310 corresponding to the selected square converts its displayed indication information before the square display units 310 corresponding to the at least one associated opponent-enabled square, indicating that the selected square is converted to the currently active square before the at least one associated opponent-enabled square.

[0245] Unit 600 for selecting the placement of pieces

[0246] According to some embodiments, the chess-playing device 10 can be configured to include a first player enabling a chess square 110a1 and a second player enabling a chess square 110a2 at the start of a game, the number of which may be equal or unequal. More specifically, such as Figure 15-17 As shown, the chess device 10 can be configured such that, at the start of the game, a first-player enabled square 110a1 and a second-player enabled square 110a2 are located in the central area of ​​the chessboard 100, which can be referred to as the "enabled central area." Within this enabled central area, there are no empty squares between the enabled squares, or more specifically, no non-enabled squares 110b. In this case, the non-enabled squares 110b, or more specifically, the optional squares 110b1, are located on the periphery of the enabled central area. According to some embodiments, the chess device 10 is configured such that, as the game progresses, the enabled squares expand outwards from the enabled central area to the outermost squares of the chessboard 100.

[0247] According to some embodiments, such as Figure 15-17The chess-playing device 10 shown is configured such that at the start of each game step, all available chess squares 110b1 are automatically displayed, and one of the available chess squares 110b1 is automatically selected as the current selected chess square 110c. Starting from the currently selected chess square 110c, one of the players can operate the move position selection unit 600 to select, for example, the desired available chess square 110b1 in sequence, until the desired chess square 110b1 is selected, i.e., the "selected chess square" mentioned above. Of course, one of the players can also choose not to operate the move position selection unit 600 based on the confirmation that the automatically displayed available chess square 110b1 is the desired available chess square 110b1. According to a more specific embodiment, considering ergonomics, and in order to conform to the human eye's observation habits, especially the habit of scanning the target area from left to right and from top to bottom, so as to facilitate one of the players to easily and intuitively lock their gaze on the automatically selected "currently selected square 110c", the chess device 10 is configured such that, at the beginning of each game step, the automatically selected "currently selected square 110c" is set to the corresponding position relative to the corresponding player. The "currently selected square 110c" is one of the selectable squares 110b1 that is far away from the corresponding position and is located in the upper left area of ​​the chessboard 100. According to one specific implementation, the "currently selected square 110c" can be the topmost optional square 110b1 located in the upper left region of the chessboard 100 relative to the corresponding position. If there is no optional square 110b1 in the upper left region of the chessboard 100 relative to the corresponding position, then the square at the top relative to the corresponding position is taken as the "currently selected square 110c". In particular, if all the optional squares 110b1 are arranged in a row, then the leftmost optional square 110b1 relative to the corresponding position is taken as the "currently selected square 110c".

[0248] According to some embodiments, such as Figure 19-22As shown, the move position selection unit 600 may be configured to include a fixed part 610 and a movable part. The movable part is configured to move relative to the fixed part 610 between at least two occupiable positions to select one of the inactive squares 110b, more specifically, from all available squares 110b1, for placing a piece. According to some embodiments, the move position selection unit 600 further includes a sensing component configured to generate a sensing signal, more specifically, the selection sensing signal described above, when the movable part moves between the at least two occupiable positions. According to some embodiments, the sensing component is configured to be communicatively connected to the control module 400. According to some embodiments, the control module 400 is configured to determine the selection of the corresponding inactive square 110b, more specifically, the available square 110b1, i.e., to determine the selected square 110c, in response to the generation or receipt of the selection sensing signal. According to one embodiment, the control module 400 is configured to control the display module 300 based on a selection sensing signal, causing the grid display unit 310 corresponding to the associated inactive grid 110b, such as the optional grid 110b1, to switch states. Exemplarily, but not exclusively, when the movable part moves from the currently occupiable position to the next occupiable position, the selected grid 110c changes from the currently selected grid 110c to the next selected grid 110c. Simultaneously, the sensing component generates a selection sensing signal, and the control module 400 controls the display module 300 based on the generation or receipt of this sensing signal, causing the grid display unit 310 corresponding to the currently selected grid 110c to switch from displaying first optional indication information to displaying second optional indication information, while the grid display unit 310 corresponding to the next selected grid 110c switches from displaying second optional indication information to displaying first optional indication information. According to some embodiments, the sensing component may include at least one fixed second sensor and at least one first sensor configured to move together with the movable part, wherein the first sensor is capable of sensing with a corresponding second sensor to generate a selection sensing signal. According to some embodiments, the second sensor may be directly disposed on the circuit board 410 of the control module 400. According to some embodiments, the sensing component is configured to sense the direction of movement of the movable part relative to the fixed part 610. According to some embodiments, the sensing component may include an electrical and / or magnetic sensing component, a light and / or color sensing component, etc.

[0249] According to some embodiments, such as Figure 1-4Figures 19-31 schematically illustrate that the movable part is in the form of a rotating ring 620, configured to rotate relative to the fixed part 610 between at least two rotational positions to select one of the optional checkerboard 110b1. According to some embodiments, the rotating ring 620 is configured to rotate relative to the fixed part 610 about a rotation axis to select one of a plurality of rotational positions, thereby correspondingly selecting one of the inactive checkerboard 110b, more specifically, one of the optional checkerboard 110b1. More specifically, the rotating ring 620 may have multiple positions, which can be rotated to switch between. More specifically, the rotating ring 620 may be configured to select one of the plurality of inactive checkerboard 110b, more specifically, one of the optional checkerboard 110b1, corresponding to each switch between two adjacent positions. According to one embodiment, the rotating ring 620 is configured to rotate clockwise and / or counterclockwise to select one of the plurality of rotational positions. According to some embodiments, the chess-playing device 10 is configured such that, in a game step, when the rotating ring 620 rotates clockwise to pass through at least one of a plurality of rotating positions and selects one of the plurality of rotating positions, one of the plurality of optional squares 110b1 is traversed according to the aforementioned first order of the plurality of optional squares 110b1 and the corresponding optional square 110b1 is selected; when the rotating ring 620 rotates counterclockwise to pass through at least one of the plurality of rotating positions and selects one of the plurality of rotating positions, one of the plurality of optional squares 110b1 is traversed according to the aforementioned second order of the plurality of optional squares 110b1 and the corresponding optional square 110b1 is selected. Exemplarily, the rotating ring 620 may occupy 15-35 rotating positions, for example, 28 rotating positions. It is understood that the number of rotating positions of the rotating ring 620 may be adaptively increased or decreased according to the diameter of the rotating ring 620.

[0250] In some embodiments, such as Figure 9 and 14As illustrated, the chess device 10 is configured such that, as the game progresses, the active squares expand from the active area, such as the central active area, outwards towards the periphery of the active area, until reaching the outer squares of the chessboard 100. In this case, each optional square 110b1 is located on the periphery of at least one active square, so all optional squares 110b1 are positioned around the active squares. Therefore, setting the movable part to the form of a rotating ring 620 conforms to the overall layout of the optional squares 110b1 on the chessboard 100 and is thus ergonomic, as this allows the optional squares 110b1 to be selected sequentially along a generally circumferential direction. This allows the player's operation of selecting a square by "rotating" and the optional squares 110b1 on the chessboard 100 to be selected sequentially and cyclically along a virtual closed trajectory, thus achieving a match between the operation and visual observation. It should be noted that the circumferential direction here refers to the direction along the periphery of the active squares, rather than a strictly circular direction.

[0251] According to some embodiments, such as Figure 1-2 As shown in Figures 25, 29-31, the rotating ring 620 is at least partially disposed around the chessboard 100. According to some embodiments, the chessboard 100 may be a circular chessboard 100, with the rotating ring 620 disposed around it. According to some embodiments, the chessboard 100 forms part of a circular cover plate 30 of the chess-playing device 10, with the rotating ring 620 disposed around the cover plate 30. Exemplarily, and not exclusively, the chessboard 100 may be internally contained within the rotating ring 620. These embodiments have numerous advantages, including: ergonomic design as described above, facilitating selection operations; enhancing the aesthetic appearance of the chess-playing device 10; not occupying additional space, contributing to the overall compactness of the chess-playing device 10, etc. According to some embodiments, the chess-playing device 10 includes a body, with at least a portion of the rotating ring 620 disposed around the body or at an end of the body 20. According to one embodiment, the chess-playing device 10 may include a cylindrical body portion, with the rotating ring 620 mounted on the cylindrical body portion. According to some embodiments, at least a portion of the rotating ring 620 is mounted within a receiving cavity defined by the cylindrical body portion. According to one specific embodiment, the rotating ring 620 is mounted at least partially around the cylindrical body. According to an alternative embodiment, the rotating ring 620 is at least partially mounted on and at least partially covers the axial end of the cylindrical body, more specifically, the checkerboard 100 or cover plate 30 is disposed at that axial end.

[0252] According to some embodiments, such as Figure 4 , 19As shown in Figure -24, the rotating ring 620 may include a first mating surface 623 and a plurality of first mating portions 624 disposed on the first mating surface 623, each first mating portion 624 corresponding to one of the plurality of rotational positions. Correspondingly, the fixing portion 610 is provided with a second mating portion, which is configured to engage with the plurality of first mating portions 624 to position the rotating ring 620 at each rotational position. More specifically, the first mating portions 624 and the second mating portions are configured to, on the one hand, allow the rotating ring 620 to be positioned at each rotational position (in other words, the aforementioned stop), and on the other hand, allow the rotating ring 620 to rotate relative to the mating portions to select a desired rotational position. According to some embodiments, the plurality of first mating portions 624 are arranged in a ring, more specifically, arranged in a ring around a rotation axis. According to some embodiments, the plurality of first mating portions 624 are evenly distributed.

[0253] According to some embodiments, such as Figure 4 , 19 -24 schematically shows that the first mating portion 624 is configured as a groove 624, which is designed to receive at least a portion of the second mating portion to position the rotating ring 620 in a corresponding rotational position. Exemplarily, the first mating surface 623 may also be provided with teeth 625, with the teeth 625 and grooves 624 alternately disposed on the first mating surface 623 such that each groove 624 is disposed circumferentially between two adjacent teeth 625. According to some embodiments, such as Figure 19-24 Schematably, the second mating portion is configured such that, as the rotating ring 620 rotates relative to the fixed portion 610, at least a portion of the second mating portion enters the groove 624 from outside the groove 624. This at least a portion of the second mating portion contacts and impacts the bottom and / or sidewalls of the groove 624 to produce an audible cue and / or a tactile vibration, such as a clicking sound. This configuration allows for enhanced human-machine interaction while allowing the user better control over the rotation of the rotating ring 620. According to some embodiments, the groove 624 is configured as a trapezoidal groove with an opening cross-section larger than its bottom cross-section. More specifically, the two circumferential end faces of the groove 624 are configured as inclined surfaces converging towards each other from the opening side to the bottom side of the groove 624. This arrangement is advantageous because, on the one hand, it allows at least a portion of the second mating part (such as the positioning part 6111 of the reed or the positioning part 613 connected to the elastic member 612, as described below) to glide more easily along the two circumferential end faces of the groove 624 and thus not to jam when the rotating ring 620 rotates; on the other hand, it allows at least a portion of the second mating part to more easily impact the circumferential end face of the groove 624 when it enters the groove 624 to provide an audible cue and / or a tactile vibration.

[0254] According to some embodiments, such as Figure 19-24The second mating portion includes elastic members 611 and 612 connected to the fixing portion 610. According to some embodiments, the elastic members 611 and 612 of the second mating portion are configured such that, when facing other parts of the first mating surface 623 except for the first mating portion 624 (such as the groove 624 described above) (such as the toothed portion 625 described above), at least a portion of the elastic members 611 and 612 abuts against the first mating surface 623 to compress the elastic members 611 and 612, more specifically, to be compressed between the first mating surface 623 and the fixing portion 610; while when facing the groove 624, at least a portion of the elastic members 611 and 612 of the second mating portion extends to release elastic stress and enters the groove 624, thereby positioning the rotating ring 620 in the corresponding rotational position.

[0255] According to some embodiments, such as Figures 19-20 As shown, the elastic element includes a leaf spring 611, which includes a positioning portion 6111 and a connecting portion 6112. The connecting portion 6112 is connected to the fixing portion 610, and the positioning portion 6111 is abutting against a first mating surface 623 (more specifically against a toothed portion 625) and entering a groove 624. According to some embodiments, the leaf spring 611 is configured as a single piece. Exemplarily, the positioning portion 6111 is configured to have a U-shaped structure, which includes a base 61110 and a first leg 61111 and a second leg 61112 extending from the base 61110. When the positioning portion 6111 is located in the groove 624, its base 61110 faces the bottom of the groove 624. Exemplarily, the connecting portion 6112 includes two connecting legs connected to the fixing portion 610, namely a first connecting leg 61121 and a second connecting leg 61122. The first connecting leg 61121 is connected to a first support leg 61111, and the second connecting leg 61122 is connected to a second support leg 61112. Exemplarily, the first connecting leg 61121 and the second connecting leg 61122 extend away from each other from the connecting portion 6112, which is respectively connected to the first support leg 61111 and the second support leg 61112, for example, in a V-shape.

[0256] According to some embodiments, such as Figure 21-23As shown, the second mating part may include an elastic member 612 connected to the fixing part 610 and a positioning member 613 mating with the elastic member 612. According to some embodiments, a first end of the elastic member 612 is connected to the fixing part 610, and the positioning member 613 is integrally formed with, connected to, or abuts against, or forms a shape with, the elastic member 612 at a second end opposite to the first end of the elastic member 612. According to some embodiments, the elastic member 612 includes a helical spring or a sheet spring. According to some embodiments, the positioning member 613 is in the form of a bead, more specifically, a round bead. According to some embodiments, the round bead-shaped positioning member 613 is configured to rollably engage with the elastic member 612. According to some embodiments, such as... Figure 21-22 As shown, the positioning element 613 is a ball, and the elastic element 612 is a spring. The positioning element 613 and the elastic element 612 are separately disposed. The spring has a recess 6121 for limiting the ball. The maximum cross-section of the recess 6121 is smaller than the maximum cross-section of the ball. Optionally, the recess 6121 is a circular recess 6121 and its diameter is smaller than the diameter of the ball, so that a part of the ball, more specifically, a part smaller than a hemisphere, can sit in the recess 6121. This structure allows the positioning element 613 to roll and sit in the recess 6121 when subjected to external force (such as the frictional force applied by the first mating surface 623 of the rotating ring 620). This reduces the friction between the positioning element 613 and the first mating surface 623 of the rotating ring 620, so that the rotating ring 620 will not jam when rotating, and the user's feel is better. According to some embodiments, the second mating part is configured such that, when it is opposite to other parts of the first mating surface 623 except for the first mating part 624 (more specifically, the groove 624) (such as the teeth 625 described above), the positioning member 613 abuts against the first mating surface 623 to compress the elastic member 612, more specifically, to be compressed between the first mating surface 623 and the fixing part 610; while when the second mating part is opposite to the groove 624, the elastic member 612 extends to release elastic stress and bias the positioning member 613 into the groove 624, thereby positioning the rotating ring 620 in the corresponding rotational position.

[0257] According to an alternative embodiment, contrary to the above embodiment, the second mating part can be configured as a groove on the fixing part 610, and the first mating part is configured to include an elastic member connected to the rotating ring 620 and an optional positioning member connected to the elastic member. More specific embodiments can be found in the above embodiments, and will not be repeated here.

[0258] According to some embodiments, such as Figure 19-23As shown, the second mating part is located radially inside the first mating surface 623 of the rotating ring 620. More specifically, at least a portion of the fixing part 610 is located radially inside the first mating surface 623 of the rotating ring 620. More specifically, the first mating surface 623 is radially opposite to the second mating part, that is, the first mating surface 623 is the radially inward surface of the rotating ring 620.

[0259] According to some embodiments, such as Figure 4 and 24 As shown, the first mating surface 623 of the rotating ring 620 can be configured to be axially opposite to the second mating part, that is, the first mating surface 623 is an axially facing surface of the rotating ring 620.

[0260] According to some embodiments, such as Figure 1-4 As shown in Figures 24-31, the rotating ring 620 includes a first rotating ring portion 621 and a second rotating ring portion 622, which are connected to each other for joint rotation. According to one embodiment, the first rotating ring portion 621 and the second rotating ring portion 622 are snap-fitted together. Exemplarily, the second rotating ring portion 622 is connected to the body 20 of the chess-playing device 10.

[0261] According to some embodiments, such as Figure 4 , 19 As shown in Figure 24, the aforementioned first mating surface 623 is disposed on the second rotating ring portion 622, and therefore the aforementioned plurality of first mating portions 624 (e.g., grooves 624) and teeth 625 are alternately disposed on the second rotating ring portion 622. According to some embodiments, the fixing portion 610 is at least partially located axially between the first rotating ring portion 621 and the second rotating ring portion 622. According to some embodiments, such as... Figure 4 and 24 As shown, the first mating surface 623 is configured as at least a portion of an axial end face of the second rotating ring portion 622. According to an alternative embodiment, such as... Figure 19-23 As shown, the first mating surface 623 is set as the radially inward surface of the second rotating ring portion 622, and the second mating part is set on the radially inner side of the first mating surface 623.

[0262] According to some embodiments, such as Figure 1-4 As shown, the outer surface 626 of the rotating ring 620 is disposed on the first rotating ring portion 621. More specifically, the outer surface 626 of the rotating ring 620 is the touch surface used by the user to operate the rotating ring 620. According to some embodiments, the first rotating ring portion 621 is at least partially located outside the body 20 of the chess device 10, and the second rotating ring portion 622 is at least partially located inside the body 20 of the chess device 10. According to some embodiments, the second rotating ring portion 622 is configured to be invisible from the outside of the chess device 10.

[0263] According to some embodiments, such as Figure 1-4 As shown, the outer surface 626 of the rotating ring 620, which is used by the user to touch and operate the rotating ring 620, is provided with a roughness-enhancing structure 6263 to facilitate the user's rotation of the rotating ring 620 and to allow the player to visually perceive that the rotating ring 620 is a rotatable component, making it easier for the player to get started with the game. According to one embodiment, the outer surface 626 of the rotating ring 620 is provided with grooves or other uneven structures. According to some embodiments, the outer surface 626 of the rotating ring 620 includes a first surface 6261 and a second surface 6262 extending laterally (intersecting or perpendicularly) relative to each other, with grooves provided on the first surface 6261 and / or the second surface 6262. According to some embodiments, the first surface 6261 and the second surface 6262 are at least a portion of the peripheral side surface and at least a portion of the end side surface on the outer side of the rotating ring 620, respectively. Optionally, the first surface 6261 and the second surface 6262 are adjacent to or intersect each other. For example, the first surface 6261 may be the outer axial surface of the first rotating ring portion 621, and the second surface 6262 may be the outer radial surface of the first rotating ring portion 621.

[0264] According to some embodiments, the chess device 10 may include a sensing component configured to generate a rotation position sensing signal, i.e., the aforementioned selection sensing signal, when the rotating ring 620 switches between the plurality of rotation positions. According to some embodiments, the chess device 10, and more specifically, the control module 400, is configured to determine the selection of a corresponding optional square 110b1 based on the generation or receipt of the rotation position sensing signal. According to one embodiment, the control module 400 is configured to control the display module 300 based on the rotation position sensing signal generated by the sensing component, such that the square display unit 310 corresponding to the associated inactive square 110b, such as the optional square 110b1, changes state. By way of example, and not exclusively, when the rotating ring 620 rotates from the current rotation position to the next rotation position, the selected square 110c changes from the currently selected square 110c to the next selected square 110c. Simultaneously, the sensing component generates a rotation position sensing signal. The control module 400 is configured to control the display module 300 based on the generation or reception of the rotation position sensing signal, so that the square display unit 310 corresponding to the currently selected square 110c switches from displaying first optional indication information to displaying second optional indication information, while the square display unit 310 corresponding to the next selected square 110c switches from displaying second optional indication information to displaying first optional indication information. According to some embodiments, the sensing component may include at least one fixedly disposed second sensor and at least one first sensor configured to rotate integrally with the rotating ring 620, for example, disposed on the rotating ring 620. The first sensor can sense each other with the corresponding second sensor to generate a rotation position sensing signal. According to some embodiments, the second sensor may be disposed on the circuit board 410 of the control module 400. According to some embodiments, the number of first or second sensors may be the same as the number of rotational positions; alternatively, the number of first or second sensors may be different from the number of rotational positions. According to some embodiments, the sensing components are configured to sense the rotational direction of the rotating ring 620 relative to the fixed portion 610.

[0265] According to some embodiments, the sensing component may include an electrical and / or magnetic sensing component, a light and / or color sensing component, etc.

[0266] According to some embodiments, such as Figure 4 , 24As shown in Figure 26, the first sensing element includes either a Hall sensor 6321 or a magnet 6311, and the second sensing element includes either a Hall sensor 6321 or a magnet 6311. More specifically, the first sensing element includes multiple magnets 6311, and the second sensing element includes a Hall sensor 6321. Exemplarily, the number of magnets 6311 is the same as the number of rotation positions. Thus, each time the rotating ring 620 rotates to change its rotation position, the magnets 6311 that rotate integrally with the rotating ring 620 will rotate past the Hall sensor 6321, and the Hall sensor 6321 can correspondingly generate a rotation position sensing signal. In some embodiments, multiple magnets 6311 and multiple grooves 624 are alternately arranged on the rotating ring 620. More specifically, a magnet 6311 receiving portion for accommodating the magnets 6311 is provided at the first mating surface 623 of the rotating ring 620, and the magnet 6311 receiving portion and the grooves 624 are alternately arranged. In some embodiments, each tooth 625 is provided with one magnet 6311 receiving portion.

[0267] In an alternative embodiment, the first sensing element includes a Hall sensor, and the second sensing element includes a plurality of magnets, exemplarily the same number of magnets as the number of rotational positions.

[0268] According to some embodiments, such as Figure 21-22As shown in Figures 27-28, the second sensing element includes a photoelectric encoder 6322, and the first sensing element includes a plurality of first light sensors 6312 and a plurality of second light sensors 6313 that can be sensed or detected by the photoelectric encoder 6322. The plurality of first light sensors 6312 and the plurality of second light sensors 6313 are alternately arranged. Exemplarily, the number of first light sensors 6312 and second light sensors 6313 is the same as the number of rotation positions. Thus, each time the rotating ring 620 rotates to change its rotation position, the first light sensors 6312 and the plurality of second light sensors 6313 that rotate with the rotating ring 620 pass through the photoelectric encoder 6322, and the photoelectric encoder 6322 can generate a rotation position sensing signal accordingly. In some embodiments, one of the first light sensors 6312 and the second light sensors 6313 is a white light sensor and the other is a black light sensor. In some embodiments, a plurality of first light-sensing portions 6312 and a plurality of second light-sensing portions 6313 are disposed on the axially facing surface of the rotating ring 620, more specifically the second rotating ring portion 622, which is radially and / or axially offset from the first mating surface 623; according to some embodiments, a plurality of first light-sensing portions 6312 and a plurality of second light-sensing portions 6313 are disposed on the first axially facing surface of the rotating ring 620, more specifically the second rotating ring portion 622, and the first mating surface 623 is disposed on the second axially opposite surface of the rotating ring 620, more specifically the second rotating ring portion 622; according to some embodiments, the first mating surface 623 is disposed on one of the radially facing surface and the axially facing surface of the rotating ring 620, more specifically the second rotating ring portion 622, and the plurality of first light-sensing portions 6312 and a plurality of second light-sensing portions 6313 are disposed on the other of the radially facing surface and the axially facing surface of the rotating ring 620, more specifically the second rotating ring portion 622.

[0269] Advantages and disadvantages module

[0270] According to some embodiments, the chess-playing device 10 further includes an advantage / disadvantage indication module. This module is configured to provide advantage / disadvantage information indicating the relative strengths and weaknesses between the number of active squares 110a1 currently used by the first player and the number of active squares 110a2 currently used by the second player. This indicates the relative strengths and weaknesses of the first and second players, providing the user with a current advantage / disadvantage indication and reminding them whether they are in a favorable or unfavorable position. This allows the user to intuitively understand the current advantage / disadvantage situation between the two players in the game and enhances the tension and excitement of the game, thus improving the gaming experience. In some embodiments, the advantage / disadvantage is expressed as a quantitative relationship. By way of example, and not exclusively, the quantitative relationship can be: the ratio of the number of first-party enabled squares 110a1 to the number of second-party enabled squares 110a2; and / or the proportion of first-party enabled squares 110a1 among all enabled squares 110a, where all enabled squares are the sum of the number of first-party enabled squares 110a1 and the number of second-party enabled squares 110a2; and / or the proportion of second-party enabled squares 110a2 among all enabled squares 110a; and so on. In some embodiments, the advantage / disadvantage indication module is configured to provide advantage / disadvantage information in real time. It should be noted that, in the sense of this document, "real time" means that during the game, after each game step, i.e., after one player finishes their move, i.e., after the flip process initiated by that player is completed, the advantage / disadvantage indication module provides current advantage / disadvantage indication information based on the number of first-party enabled squares 110a1 and second-party enabled squares 110a2 on the current board 100, and can be set to remain until the other player finishes their move, i.e., after a flip process is completed. According to some embodiments, the advantage / disadvantage indication module is configured to update the advantage / disadvantage information after the conversion module operates to complete the flipping process. According to some embodiments, the control module 400 is configured to communicate with the advantage / disadvantage indication module to control its operation. According to further embodiments of the first and third variations described above, the control module 400 is configured to control the advantage / disadvantage indication module to update the advantage / disadvantage information based on each operation of the move placement confirmation units 500 and 700. According to a further embodiment of the second variation described above, the control module 400 is configured to control the advantage / disadvantage indication module to update the advantage / disadvantage information based on the move placement selection unit 600 satisfying the conversion condition. According to some embodiments, the advantage / disadvantage indication module is configured to continuously provide advantage / disadvantage information throughout each game phase. According to an alternative embodiment, the advantage / disadvantage indication module may be configured to provide advantage / disadvantage information in a non-continuous manner.

[0271] According to some embodiments, such as Figure 1-4As shown in Figures 10, 9-18, 24-25, 27, and 30-31, the advantage / disadvantage indication module includes an indicator light assembly 800, which includes multiple indicator light units 810, referred to herein as "LED beads" 810. The indicator light units exemplarily include LEDs. More specifically, the indicator light assembly 800 is configured to be controllable by the control module 400. According to some embodiments, the multiple LED beads 810 of the indicator light assembly 800 are directly mounted on the circuit board 410 of the control module 400. According to some embodiments, the LED beads 810 can be configured to change at least one of their on / off state, brightness, color, flashing mode, etc. According to some embodiments, the multiple LED beads 810 can be controlled independently of each other.

[0272] According to some embodiments, during the game process of the chess device 10, such as Figure 9-18 As shown, the plurality of LED beads 810 includes first-state LED beads 811 in a first state and second-state LED beads 812 in a second state, the second state being different from the first state. The indicator light assembly 800 can be configured to provide advantage / disadvantage information through at least one of the following: the number of first-state LED beads 811 and the number of second-state LED beads 812; the proportion of first-state LED beads 811 among the plurality of LED beads 810, and / or the proportion of second-state LED beads 812 among the plurality of LED beads 810; the ratio of the area occupied by first-state LED beads 811 to the total area of ​​the indicator light assembly 800, and / or the ratio of the area occupied by second-state LED beads 812 to the total area of ​​the indicator light assembly 800. More specifically, when using the indicator light assembly 800 to provide advantage / disadvantage information, the plurality of LED beads 810 of the indicator light assembly 800 are divided into first-state LED beads 811 and second-state LED beads 812. According to some embodiments, each of the first state and the second state represents at least one of the following: the on or off state of the LED 810; the illumination color of the LED 810 when it is on; the illumination brightness of the LED 810 when it is on; and the illumination flashing pattern of the LED 810 when it is on. According to some embodiments, the plurality of LEDs 810 in the indicator light assembly 800 can be divided into first-state LEDs 811 and second-state LEDs 812 that are not mixed with each other, i.e., the first-state LEDs 811 are continuously distributed, and the second-state LEDs 812 are continuously distributed. More specifically, the indicator light assembly 800 is divided into a first segment and a second segment, where the first segment can be a segment where the first-state LEDs 811 are distributed, and the second segment can be a segment where the second-state LEDs 812 are distributed. This allows the human eye to more intuitively and clearly determine the current advantage or disadvantage of both sides in the game.

[0273] According to some embodiments, such as Figure 9-16As shown, the first state is the lit state, and the second state is the off state. Specifically, in the first state, LED 811 is the lit LED, and in the second state, LED 812 is the off LED. This allows for performance indication in a power-saving manner. According to some embodiments, during gameplay, such as... Figure 9-14 As shown, the control module 400 is configured to control the indicator light assembly 800 such that, between each game step, corresponding first-state LED beads 811 are alternately illuminated in a first illumination state and a second illumination state, the first illumination state and the second illumination state being different from each other. The proportion of the first-state LED beads 811 illuminated in the first illumination state among the plurality of LED beads 810 represents the proportion of the first-party activated square 110a1 among all activated squares, and the proportion of the first-state LED beads 811 illuminated in the second illumination state among the plurality of LED beads 810 represents the proportion of the second-party activated square 110a2 among all activated squares. Alternatively or additionally, the ratio of the area occupied by the first-state LED beads 811 illuminated in the first illumination state to the total area of ​​the indicator light assembly 800 can represent the proportion of the first-party activated square 110a1 among all activated squares, and the ratio of the area occupied by the first-state LED beads 811 illuminated in the second illumination state to the total area of ​​the indicator light assembly 800 can represent the proportion of the second-party activated square 110a2 among all activated squares. According to some embodiments, the chess-playing device 10 is configured to indicate the player's move in a corresponding game step through a first and second illumination state of a first state LED 811. More specifically, if the first state LED 811 is currently illuminated in the first illumination state, it indicates that the player in the current game step is the first player; conversely, if the first state LED 811 is currently illuminated in the second illumination state, it indicates that the player in the current game step is the second player. According to some embodiments, when the first state LED 811 is illuminated in the first illumination state, it indicates that the currently activated square is the first player's activated square 110a1, and when the first state LED 811 is illuminated in the second illumination state, it indicates that the currently activated square is the second player's activated square 110a2. These embodiments allow the indicator light assembly 800 to have the dual function of indicating the strength and weakness of both players and the corresponding player's move. Figure 9-13 This shows the status of indicator light component 800 during a game step. Figure 14 The status of indicator light assembly 800 in the next game step is shown. It can be seen that in these two game steps, the first state LED 811 is lit in purple and yellow respectively. Figure 9-13 The purple LED 811 in the first state can be used to indicate the proportion of the purple side's (first side's) activated squares in all activated squares 110a, that is, to indicate the purple side's advantages and disadvantages. On the other hand, it can be used to indicate that the purple side is the player in the current game step. Figure 14The yellow LED 812 in the first state can be used to indicate the proportion of the yellow (second) player's (second) active squares in all active squares 110a, that is, to indicate the yellow player's advantage or disadvantage. On the other hand, it can also be used to indicate that the player who plays in the current game step is the yellow player.

[0274] According to some embodiments, such as Figure 17-18 As shown, the first illuminated state is the first color, and the second illuminated state is a second color different from the first color. For example... Figure 17-18 As shown, according to some embodiments, the first activation indication information for indicating the first activated grid 110a1 is represented by a first illumination state, such as a first color, and the second activation indication information for indicating the second activated grid 110a2 is represented by a second illumination state, such as a second representation. That is, the illumination state of the LED beads 810 used to indicate the proportion of the number of the corresponding activated grids in all activated grids 110a is consistent with the activation indication information used to indicate the corresponding activated grids. This allows for a very intuitive indication of the proportion of the number of LED beads 810 illuminated in the corresponding illumination state in all LED beads 810 or the proportion in the total area of ​​the indicator light assembly 800 representing the proportion of the number of the corresponding activated grids in all activated grids.

[0275] According to some embodiments, such as Figure 9-13 As shown (representing a complete game step), each game step can include two phases, namely the first phase before the flipping process begins. Figure 9-10 The first stage (11-13) begins after the flipping process. In the first stage, the chess device 10 is configured to indicate the player's move in the corresponding game step via the first illumination state, more specifically, the first color, and the second illumination state, or more specifically, the second color of the first state LED 811. For example, if the current first state LED 811 is illuminated in the first color, it indicates that the player in the current game step is the first player; conversely, if the current first state LED 811 is illuminated in the second color, it indicates that the player in the current game step is the second player. Simultaneously, the proportion of the current first state LED 811 in terms of quantity or area among all LEDs 810 is used to represent the current advantage / disadvantage information. Figure 13 In the second phase, the advantage / disadvantage indicator module, more specifically the indicator light assembly 800, updates the advantage / disadvantage information. More specifically, after the flipping process is complete, as described above, the selected square and its associated opponent's enabled square are converted to the current player's enabled square. Therefore, the number of first-player enabled squares 110a1 and second-player enabled squares 110a2 on the board 100 will change. The advantage / disadvantage indicator module is configured to update the advantage / disadvantage information based on this change and display the updated information. Figure 13More specifically, the control module 400 controls the advantage / disadvantage indication module to update the advantage / disadvantage information and display the updated information. According to one embodiment, the updated advantage / disadvantage information is presented in the same way as the previous information. For example, if the player in the current game move is the first player, in the first stage, the advantage / disadvantage information can be represented by the proportion of the number or area of ​​the first-state LED beads 811 lit in the first color among all the LED beads 810; in the second stage, the updated advantage / disadvantage information is still represented by the proportion of the number or area of ​​the first-state LED beads 811 lit in the first color among the LED beads 810; and vice versa.

[0276] According to some embodiments, the first phase of each game step may include an initial phase ( Figure 9 It is the initial stage of a game. Figure 14 To follow Figures 9-13 The initial stage of the second game step after the first game step). Taking the first player as an example, the explanation should be similar if the first player is the first player; the explanation for the second player is the same and need not be repeated. According to some embodiments, in the initial stage ( Figure 9-10The chessboard 100 initially has a first-side activated square 110a1 and a second-side activated square 110a2. The square display unit 310 corresponding to the first-side activated square 110a1 displays first activation information, and the square display unit 310 corresponding to the second-side activated square 110a2 displays second activation information. Furthermore, at this time, the first state LED beads 811 of the advantage / disadvantage indicator module, more specifically the indicator light assembly 800, are lit in a first color, and the second state LED beads 812 are off. The proportion of the number or area of ​​the LED beads 810 lit in the first color among all LED beads 810 indicates the proportion of the first-side activated square 110a1 among all activated squares. According to some embodiments, the first stage may include an optional square 110b1 display stage after the initial stage, in which the chess device 10 is configured to display all optional squares 110b1 on the chessboard 100, and more specifically, the display module 300 is configured to display optional indicator information in the square display unit 310 corresponding to the optional square 110b1. According to one embodiment, the chess device 10 is further configured to automatically select an optional square 110b1 during this stage, and the square display unit 310 corresponding to the automatically selected optional square 110b1 displays first optional indication information, while the square display units 310 corresponding to the remaining optional squares 110b1 display second optional indication information. According to some embodiments, the first stage may include a square selection stage after the initial stage or after the optional square 110b1 display stage, more specifically, an optional square 110b1 selection stage. It should be noted that this stage may or may not exist depending on the circumstances; that is, if the optional square 110b1 automatically selected in the optional square 110b1 display stage is the optional square 110b1 that the user expects to select, this stage may be omitted. More specifically, during the selection phase of the optional square 110b1, the move position selection unit 600 can be operated to select one of the multiple optional squares 110b1, and the optional square 110b1 displaying the first optional indication information and the second optional indication information changes with the operation of the move position selection unit 600.

[0277] As described above, when the conversion module operates to convert a selected square into a currently enabled square, the at least one associated opponent enabled square is converted into a currently enabled square.

[0278] According to some embodiments, the second phase of each game step can be further divided into a flipping phase ( Figure 11-12 ), Enable the checkerboard 110a layout update display phase ( Figure 13 ) and the stage of updating and displaying advantages and disadvantages information ( Figure 13The flipping phase is the phase where selected squares and associated opponent-enabled squares are converted into the current player's enabled squares. Detailed instructions for this phase can be found above. The enabled square 110a layout update display phase updates the layout display of the first player's enabled squares 110a1 and the second player's enabled squares 110a2 on the chessboard 100 after the flipping phase is completed. The advantage / disadvantage information update display phase can be performed simultaneously with the flipping phase and the enabled square 110a layout update display phase, or it can be performed after the enabled square 110a layout update display phase. Specifically, the advantage / disadvantage indicator module updates the advantage / disadvantage information and displays the updated advantage / disadvantage information based on the changes in the number of first player enabled squares 110a1 and the number of second player enabled squares 110a2 after the flipping phase. According to some embodiments, after one of the players confirms the selectable square 110b1 to complete the "placement", the proportion of that player's selected squares to all selected squares 110a increases, and the corresponding advantage / disadvantage indicator beads 810 of that player gradually increase in dynamic change and can be accompanied by sound effects. Through this setting, the prompting effect is further enhanced and the game experience is improved.

[0279] It should be noted that, according to some embodiments, the game steps may not have a phase for updating and displaying advantage and disadvantage information. Instead, the advantage and disadvantage information updated compared to the previous game step may be displayed directly at the beginning of each game step.

[0280] According to some embodiments, such as Figure 13-14 As shown, the chess device 10 is configured to automatically switch to the next game step after the second stage is completed, and therefore can automatically switch the display of advantage and disadvantage information. Figure 13 This marks the end of a game step. Figure 14 (This is the start of the next game step). For example, if the player in the current game step is the first player, the advantage / disadvantage indicator module indicates the percentage of the number or area of ​​the first-state LED beads 811 lit in the first lighting state (more specifically, the first color) among all LED beads 810. In the next game step, the player becomes the second player, and the advantage / disadvantage indicator module switches to indicating the percentage of the number or area of ​​the second-state LED beads 812 lit in the second lighting state (more specifically, the second color) among all LED beads 810.

[0281] According to some embodiments, such as Figure 9-18As shown, the first state of LED 810 is represented by a first illuminated state, and the second state of LED 810 is represented by LED 812 by a second illuminated state, which is different from the first illuminated state. That is, LED 811 in the first state is LED 810 illuminated in the first illuminated state, and LED 812 in the second state is LED 810 illuminated in the second illuminated state. The first illuminated state can be a first illuminated color, and the second illuminated state can be a second illuminated color different from the first illuminated color. Further, the proportion of LED 811 in the first state among the plurality of LEDs 810 represents the proportion of the first activated grid 110a1 in the activated grid 110a; the proportion of LED 812 in the second state among the plurality of LEDs 810 represents the proportion of the second activated grid 110a2 in the activated grid 110a. Alternatively or additionally, the ratio of the area occupied by the first-state LED 811 to the total area of ​​the indicator light assembly 800 can represent the proportion of the first-party activated grid 110a1 in the activated grid 110a, and the ratio of the area occupied by the second-state LED 812 to the total area of ​​the indicator light assembly 800 can represent the proportion of the second-party activated grid 110a2 in the activated grid 110a. According to some embodiments, the control module 400 is configured to indicate the player in a corresponding game step by highlighting one of a first illumination color and a second illumination color. Exemplarily, and not exclusively, the control module 400 is configured to highlight one of the first illumination color and the second illumination color by adjusting the brightness and / or illumination frequency of the first illumination color and the second illumination color. For example, if, in the current game step, the brightness of the LED 810 of the indicator light assembly 800 illuminated with the first illumination color is higher than that of the LED 810 illuminated with the second illumination color, then the current player is the first player.

[0282] According to some embodiments, the indicator light assembly 800 is also configured to provide a winning indication message to the winning side at the end of the game. According to some embodiments, at the end of the game, all LEDs 810 are illuminated, optionally accompanied by flashing. According to some embodiments, at the end of the game, the entire indicator light assembly 800 is illuminated in a first illuminated state or a second illuminated state, optionally accompanied by flashing, to indicate whether the winning side is the first or second side. According to some embodiments, at the end of the game, the grid display unit 310 corresponding to the winning side's activated grid displays the corresponding activation indication message; optionally, the display module 300 no longer displays the activation indication message for the losing side's activated grid.

[0283] According to some embodiments, such as Figure 1-4The indicator light assembly 800, denoted as 10, 9-18, 24-25, 27, and 30-31, is configured to surround the chessboard 100. More specifically, the plurality of LEDs 810 are evenly distributed around the chessboard 100. According to some embodiments, the indicator light assembly 800 is configured as a light strip 800 with a closed shape. Exemplarily, and not exclusively, the light strip 800 is configured to have one of the following shapes: circular; rectangular; elliptical; equilateral polygon; more specifically, "polygon" means an even number of sides. According to some embodiments, the light strip 800 is configured as a circular or elliptical light strip 800, and the chessboard 100 is at least partially inscribed within the light strip 800. According to some embodiments, the chessboard 100 may be configured as a circular chessboard 100. According to some embodiments, the chess device 10 has a cylindrical overall shape or is at least partially cylindrical. According to some embodiments, the plurality of LEDs 810 of the indicator light assembly 800 are disposed on the circuit board 410 of the control module 400, in the peripheral area of ​​the circuit board 410. According to one embodiment, the circuit board 410 is configured to have one of the following shapes: circular; rectangular; elliptical; equilateral polygon; more specifically, "polygon" means an even number of sides.

[0284] In some embodiments, as described above, the chess device 10 may have a first occupying point 11 and a second occupying point 12. Exemplarily, the chess device 10 may use the aforementioned first occupying point 11 and second occupying point 12 in a single-player game mode. In some embodiments, as described above, the chess device 10 may have a third occupying point 13 and a fourth occupying point 14. Exemplarily, the chess device 10 may use the aforementioned third occupying point 13 and fourth occupying point 14 in a two-player game mode. According to some embodiments, as described above, during the game, the first state LED 811 is an LED 810 in an illuminated state, and the second state LED 812 is an LED 810 in an off state. In some embodiments, such as... Figure 9As shown in Figures 14 and 16, the indicator light assembly 800 is configured such that, during the game, the first state LED 811 alternately corresponds to the first capture point 11 and the second capture point 12, or alternately corresponds to the third capture point 13 and the fourth capture point 14, between different game steps to indicate the corresponding player in the current game step. For example, in the game, if the first state LED 811 corresponds to the first or third capture point 13 in the current game step, it indicates that the current player is the first player; if the first state LED 811 corresponds to the second or fourth capture point 14, it indicates that the current player is the second player. Therefore, in these embodiments, the indicator light assembly 800 can very intuitively indicate the current player, especially by combining the first state LED beads 811 in different lighting states as described above; more specifically, the current player and advantage / disadvantage information can be clearly and intuitively indicated by the following combination: the position of the first state LED bead 811; the lighting state of the first state LED bead 811 (e.g., a first color or a second color); optionally, the color of the first activation indication information and the color of the second activation indication information, i.e., the color of the first player's activated square 110a1 and the color of the second player's activated square 110a2.

[0285] It should be noted that, in the context of this article, such as Figure 9-18 As shown, "corresponding to a certain occupancy point distribution" can be understood as the corresponding LED beads 810 being distributed along two opposite circumferential directions with the intersection of the corresponding axis passing through the occupancy point and the center line of the checkerboard area 100a with the LED strip 800 as the midpoint.

[0286] According to alternative embodiments, as described above and as follows Figure 17-18 As shown, during the game, the first state LED 811 is the LED 810 in the first illuminated state, and the second state LED 812 is the LED 810 in the second illuminated state, which is different from the first illuminated state. For example, the first illuminated state is a first color, and the second illuminated state is a second color. In such an embodiment, the first state LED 811 can be further configured to always correspond to the distribution of the first or third occupant point 13, and the second state LED 812 can always correspond to the distribution of the second or fourth occupant point 14.
