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 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, current board games lack human-computer interaction, making them tedious and failing to maintain player interest for extended periods. 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 games. All these problems contribute to a poor user experience and low satisfaction.

[0003] While existing flip chess software programs can automatically execute the 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 as their platform. 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. Utility Model Content

[0172] Overall Solution for Chess Equipment

[0173] This disclosure proposes a chess-playing device 10. According to one embodiment, such as Figure 1-4Figures 25, 29-31 schematically illustrate that the chess-playing device 10 includes a chessboard 100 capable of forming a plurality of squares 110. According to some embodiments, the chessboard 100 has square-dividing structures on or within the chessboard 100, such as grooves, ridges, flat lines, or lines engraved inside the chessboard 100 by laser to form the square-dividing structures, thereby dividing the chessboard 100 into a plurality of squares 110. Alternatively or additionally, the chessboard 100 can form the plurality of squares 110 by projection or illumination from other components. 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 an exemplary embodiment, the chessboard 100 constitutes at least a portion of a cover 30 that closes the opening of the receiving cavity 23.

[0174] 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 chess square 110a includes the first-party activated chess square 110a1 and the second-party activated chess square 110a2, both in an activated state. More specifically, the first-party activated chess square 110a1 belongs to the first party (first mover) in the game phase of the chess device 10, and the second-party activated chess square 110a2 belongs to the second party (second mover) in the game phase of the chess device 10. More specifically, "activated state" is "occupied state," meaning that a chess square 110 in an activated state has been occupied by one party. More generally, "occupied chess square" means that a chess square 110 has been placed by one party.

[0175] 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 the current player's active square 110a. This square 110b used for conversion may be referred to as 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 the current player's active square. 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.

[0176] 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, "current player" refers to 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" refers to a "round," "set," or "one" of games, which can correspond to multiple rounds of alternating operations by the two players from the start to the end of the game, and a "game step" includes one player making a move, placing a piece, or performing a related operation.

[0177] 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 110. 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 displayed by the chess square display unit 310. The arrangement of 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 arrangement of the display module 300 also allows for the elimination of physical chess pieces, thereby allowing users to conveniently use the chess-playing device 10 in any location.

[0178] 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 independently controlled from each other. 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).

[0179] The first variant of chess equipment 10

[0180] According to some embodiments, such as Figure 5-7 As shown, the conversion module may include a first move position confirmation unit 500, which is configured to convert a selected square into a currently active square. More specifically, the first move position confirmation unit 500 is operable to convert a selected square into a currently active square. According to some embodiments, the chess device 10 is configured to, when the first move position confirmation unit 500 is operated, also convert at least one associated opponent active square into a currently active square. According to some embodiments, the display module 300 is configured to change the display state of the corresponding square display unit 310 when the first move position confirmation unit 500 is operated. According to some embodiments, the display module 300 is configured to, when the first move position confirmation unit 500 is operated, convert the square display unit 310 corresponding to the selected square to display 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 (e.g., from...). Figures 5 to 7 (This transition is shown). According to a further or alternative embodiment, the display module 300 is configured such that, upon operation of the first move position confirmation unit 500, the move display unit 310 corresponding to the at least one associated opponent-enabled move is switched from displaying one of the first and second activation indication messages to displaying one of the first and second activation indication messages to indicate the transition from the at least one associated opponent-enabled move to the current player-enabled move. This ensures human-computer interaction and game enjoyment, and enables the "flipping" action of the opponent's piece after the current player "places a move," enhancing the game experience.

[0181] 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 5-7 As shown, when 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.

[0182] like Figure 5-7 As shown, according to some embodiments, the conversion module may include a 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 a button, etc.

[0183] According to some embodiments, such as Figure 5-7 As shown, the inactive square 110b may include optional squares 110b1. More specifically, in the current game step of a game phase, the inactive square 110b may include optional squares 110b1 and unselectable squares 110b2. Optional squares 110b1 are inactive squares 110b that can be converted into currently active squares in the current game step. More specifically, unselectable squares 110b2 are squares 110 that cannot be selected in the current game step. More specifically, the selected squares mentioned above are 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-party active squares 110a1 and associated second-party active squares 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. According to some embodiments, the optional square 110b1 varies in different game steps within a game phase.

[0184] 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 110 in the current game step 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.

[0185] According to some embodiments, the display module 300 can be configured such that when the first move position confirmation unit 500 operates, 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 110 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 display module 300 is further configured such that when the first move position confirmation unit 500 operates, the square display units 310 corresponding to the remaining selectable squares 110b1 (excluding the selected square) in the selectable squares 110b1 change from displaying selectable indication information to a state of being off or having reduced brightness (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 110, quickly judge the current changes in the game, and also allows for reduced power consumption.

[0186] 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.

[0187] The second variant of chess equipment 10

[0188] 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 110 from the range of non-selected squares 110b. This allows the user to make more targeted selections through the placement selection unit 600, eliminating unnecessary steps, speeding up the game, and preventing users from becoming annoyed by cumbersome selection operations.

[0189] 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 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 a selection operation by 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 enabled square based on the generation or receipt of the confirmation conversion signal.

[0190] According to some embodiments, the display module 300 is configured such that when the selection operation of the move position selection unit 600 satisfies the conversion condition, the move display unit 310 corresponding to the selected move is switched to displaying one of a first activation indication information and a second activation indication information to indicate the conversion from the selected move to the currently activated move. More specifically, the display module 300 is configured such that when the selection operation of the move position selection unit 600 satisfies the conversion condition, the move display unit 310 corresponding to the at least one associated opponent activated move is switched 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 conversion from the at least one associated opponent activated move to the currently activated move.

[0191] According to some embodiments, the move selection unit 600 may be in the form of a knob, button, or touch control. According to some embodiments, the chess device 10 may include a single move selection unit 600, operable by each of the two players. According to some embodiments, the chess device 10 may include two move selection units 600, each operable by one of the two players.

[0192] 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 110 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 110 that the move position selection unit 600 "visits" or "traverses" at the current moment. According to some embodiments, the display module 300 is configured to display the selection indication information on the square display unit 310 corresponding to the selected square 110c when the move position selection unit 600 performs a selection operation. Exemplarily, the square display unit 310 corresponding to the selected square 110c can be configured to switch from an off state to displaying the selection indication information. According to a further embodiment, the display module 300 can be configured such that when the selection operation of the move selection unit 600 satisfies the aforementioned conversion conditions, the move display unit 310 corresponding to the selected move changes from displaying selection indication information to displaying one of the first activation indication information and the second activation information to indicate the conversion from the selected move to the currently activated move. This configuration allows the display module 300 to present the dynamic process of the conversion from the selected move to the currently activated move, making it easy for the user to confirm which move 110 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.

[0193] 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. The optional square 110b1 is a square 110 that can be selected for transformation in the current game step, that is, a square 110 that can be selected in the current move step to become the current player's active square 110a. More specifically, the selected square 110c is one of the optional squares 110b1. More specifically, the unselectable square 110b2 is a square 110 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.

[0194] 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(In section -18, marked with ③ in light blue) 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 110 in the current game step that can be placed or transformed, assisting the player in quickly locking in possible placement positions, reducing the game difficulty and entry barrier, accelerating the game process, and enhancing human-computer interaction and game fun.

[0195] According to some embodiments, the display module 300 is configured such that when the selection operation of the move position selection unit 600 satisfies the above-mentioned conversion conditions, the move display unit 310 corresponding to the selected move 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 move to the currently activated move. This configuration allows the display module 300 to present the dynamic process of the conversion from the selected move to the currently activated move, making it easy for the user to confirm which move 110 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 display module 300 is configured such that when the selection operation of the move position selection unit 600 satisfies the above-mentioned conversion conditions, the move display unit 310 corresponding to the other optional moves 110b1 besides the selected move 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 110, quickly judge the current changes in the game, and also allows for reduced power consumption.

[0196] 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 optional indication information includes first optional indication information that differs from each other (e.g., ...). Figure 9-10 (Identified in dark blue as ④ in sections 14-18) and the second optional instruction information, such as Figure 9-10 (In sections 14-18, marked with a light blue ③), optional information is used to indicate the selected square 110c, and second optional 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.

[0197] According to some embodiments, the display module 300 is configured such that when the move position selection unit 600 operates, 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 move position selection unit 600's selection operation has positioned the currently selected move 110b1 as the currently selected move 110c. According to some embodiments, the display module 300 is further configured such that when the move position selection unit 600 operates, the move display unit 310 corresponding to the previously selected move 110c switches from displaying first optional indication information to displaying second optional indication information, indicating 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 one of the other optional moves 110b1. According to some embodiments, in one game step, the move position selection unit 600 can be configured to position one of the optional moves 110b1 as the currently selected move 110c for each selection operation. For example, the move position selection unit 600 performs two selection operations: a first selection operation and a second selection operation. The selectable square 110b1 chosen in the first selection operation of the move position selection unit 600 is called the previously selected square 110c, and the selectable square 110b1 chosen in the second selection operation of the move position selection unit 600 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 the first selectable square. The information is displayed; and 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 "other optional move 110b1", that is, it is no longer the selected move 110c. 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.

[0198] 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 chess device 10 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 sorting of this sorting to perform the selection operation.

[0199] According to some embodiments, the display module 300 is configured such that when the selection operation of the move position selection unit 600 meets the conversion conditions, 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 conversion from the selected move to the currently activated move. This configuration allows the display module 300 to present the dynamic process of the conversion from the selected move to the currently activated move, making it easy for the user to confirm which move 110 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 display module 300 is also configured such that when the selection operation of the move position selection unit 600 meets the conversion conditions, the move display unit 310 corresponding to the other optional moves 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 110, quickly judge the current changes in the game, and also allows for reduced power consumption.

[0200] 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 110, and also helps to save power.

[0201] The third variant of chess equipment 10

[0202] 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 operable to convert a selected square into a currently active square. According to some embodiments, the chess device 10 is configured to convert at least one associated opponent-activated square into a currently active square when the second move position confirmation unit 700 is operated. According to some embodiments, the display module 300 is configured to, when the second move position confirmation unit 700 is operated, convert the square display unit 310 corresponding to the selected square to display 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 display module 300 is configured such that, when the second move position confirmation unit 700 operates, the move display unit 310 corresponding to the at least one associated opponent's activated move is switched from displaying one of the first and second activation indication messages to displaying one of the first and second activation indication messages 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 enjoyment, and realizes the "flipping" action of the opponent's move after the current player "places a move," enhancing the game experience.

[0203] 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 a button, etc.

[0204] 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 110 from the range of non-selected squares 110b. This allows the user to make more targeted selections through the placement selection unit 600, eliminating unnecessary steps, speeding up the game, and preventing users from becoming annoyed by cumbersome selection operations.

[0205] 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.

[0206] 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 110 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 110 that the move position selection unit 600 currently "accesses," "traverses," or "locks." According to some embodiments, the display module 300 is configured to display the selection indication information on the square display unit 310 corresponding to the selected square 110c when the move position selection unit 600 is operating. Exemplarily, the square display unit 310 corresponding to the selected square 110c can be configured to switch from an off state to displaying the selection indication information. According to a further embodiment, the display module 300 is configured such that when the conversion module operates to convert a selected square to a currently enabled square, the square display unit 310 corresponding to the selected square switches from displaying selection indication information to displaying one of a first enable indication information and a second enable information to indicate the conversion from the selected square to the currently enabled square. This configuration allows the display module 300 to present the dynamic process of the conversion from the selected square to the currently enabled square, making it easy for the user to confirm which square 110 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.

[0207] According to some embodiments, such as Figure 9-10 Figures 14-18 schematically illustrate that a non-enabled square 110b may include an optional square 110b1. More specifically, in the current game step of a game phase, a non-enabled square 110b may include an optional square 110b1 and a non-selectable square 110b2. An optional square 110b1 is a square 110 that can be selected for transformation in the current game step, that is, a square 110 that can be selected in the current move to transform into the current player's enabled square 110a.

[0208] More specifically, the unselectable square 110b2 is a square 110 that cannot be selected in the current game step. More specifically, the selected square 110c mentioned above is one of the selectable squares 110b1. According to some embodiments, each selectable 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 selectable 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 selectable square 110b1. According to some embodiments, the selectable squares 110b1 vary in different game steps within a game phase. According to some embodiments, in the game steps of the game phase, the first move position confirmation unit 500, as described in the first variant, is configured to be effective only when operating on the selectable square 110b1. More specifically, only the first move position confirmation unit 500 corresponding to the selectable square 110b1 is operable. According to some embodiments, in the game steps of the game phase, the move position selection unit 600, as described in the second and third variants, is configured to perform a selection operation only to "access" the selectable square 110b1 in the inactive square 110b, and cannot "access" the inactive square 110a in the active square 110a and the non-selectable square 110b2 in the inactive 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.

[0209] 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 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 110 in the current game step 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.

[0210] According to some embodiments, the display module 300 can be configured such that, when the second move position confirmation unit 700 is operated, the move display unit 310 corresponding to the selected move 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 move to the currently activated move. This configuration allows the display module 300 to present the dynamic process of the transition from the selected move to the currently activated move, making it easy for the user to confirm which move 110 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 display module 300 can also be configured such that, when the second move position confirmation unit 700 is operated, the move display unit 310 corresponding to the other optional moves 110b1 besides the selected move changes from displaying optional indication information to being off (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 110, quickly judge the current game situation, and also allow for reduced power consumption.

[0211] 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 optional indication information includes first optional indication information that differs from each other (e.g., ...). 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.

[0212] According to some embodiments, the display module 300 is configured such that when the move position selection unit 600 performs a selection operation, the grid display unit 310 corresponding to the selected grid 110c switches from displaying second optional indication information to displaying first optional indication information, thereby intuitively indicating that the selectable grid 110b1 currently located by the move position selection unit 600 is the currently selected grid 110c. According to some embodiments, the display module 300 can also be configured such that when the move position selection unit 600 performs a selection operation, the grid display unit 310 corresponding to the previously selected grid 110c switches from displaying first optional indication information to displaying second optional indication information, indicating that the previously selected grid 110c is no longer the selected grid 110c after further operation by the move position selection unit 600, but belongs to one of the other optional grids 110b1. According to some embodiments, in one game step, the move position selection unit 600 can be configured to locate one of the optional grids 110b1 as the currently selected grid 110c for each selection operation. For example, the move position selection unit 600 performs two selection operations: a first selection operation and a second selection operation. The selectable square 110b1 chosen in the first selection operation of the move position selection unit 600 is called the previously selected square 110c, and the selectable square 110b1 chosen in the second selection operation of the move position selection unit 600 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 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.

[0213] 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 chess device 10 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 sorting of this sorting to perform the selection operation.

[0214] According to some embodiments, the display module 300 can be configured such that, when the second move position confirmation unit 700 operates, 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 110 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 display module 300 can also be configured such that when the second move position confirmation unit 700 operates, the square display unit 310 corresponding to the other selectable squares 110b1 changes from displaying the second selectable 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 transformation and flipping squares 110, quickly judge the current board position changes, and also allows for reduced power consumption.

[0215] 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 110, and also helps to save power.

[0216] According to some embodiments, the move selection unit 600 and the move confirmation unit 700 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 600 and is configured to perform a selection operation when rotated, while the button, for example, corresponds to the second move confirmation unit 700 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.

[0217] General configuration of chess and card game device 10

[0218] In all variations of this application, according to some embodiments, the chess device 10 is configured to automatically switch between successive game steps during the game. More specifically, the chess device 10 is configured to immediately or after a period of time 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 display module 300 is configured to display the optional square 110b1 in the next game step after proceeding to the next game step. For example, the square display unit 310 corresponding to the optional square 110b1 in the next game step can be controlled 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 110b1A.

[0219] 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 110 includes a certain number of first-player enabled chessboards 110a1 and second-player enabled chessboards 110a2. According to some embodiments, the display module 300 is configured to, at the start of a game, display units 310 corresponding to the first-player enabled chessboards 110a1 display first-player enabled indication information, and display units 310 corresponding to the second-player enabled chessboards 110a2 display second-player enabled indication information. 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 110 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.

[0220] 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 110 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 110 on the chessboard 100 are arranged in a square array; more specifically, the plurality of squares 110 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.

[0221] According to some embodiments, exemplarily, such as Figure 1 , 3As shown in -4, 25, 29-31, the chess device 10 may include a cover plate 30, and the 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 according to the third variant, or the move position selection unit 600 according to the second 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.

[0222] 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 chess-playing 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; exemplarily, the mode switching component 40 may be in the form of a button or key; exemplarily, the mode switching component 40 may be in the form of a touchscreen.

[0223] 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.

[0224] 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.

[0225] 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.

[0226] According to some embodiments, Figure 9 ,11 -17 schematically shows 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. According to some embodiments, the first player is a user (in the sense of this document, a user refers to an actual entity 20, which can be a human or a robot) among the two players in the human-computer mode, and the chessboard device 10 itself, as the second player, 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.

[0227] According to some embodiments, the chess device 10 may include two first move position confirmation units 500 according to a first variation, the two first move position confirmation units 500 being positioned near the first occupying point 11 and the second occupying point 12, respectively, for use by corresponding parties of the two players, especially in a two-player game mode. According to some embodiments (not shown), the chess device 10 may include two move position selection units 600 according to a second variation, the two move position selection units 600 being positioned near the first occupying point 11 and the second occupying point 12, respectively, for use by corresponding parties of the two players, especially in a two-player game mode. According to some embodiments, the chess device 10 may include two second move position confirmation units 700 or integrated units according to a third variation, the two second move position confirmation units 700 or the two integrated units being positioned near the first occupying point 11 and the second occupying point 12, respectively, for use by corresponding parties of the two players, especially in a two-player game mode.

[0228] 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.

[0229] 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.

[0230] According to some embodiments, the chessboard 100 area is one of the following shapes: circular; rectangular; elliptical; equilateral polygon, where "polygon" means an even number of sides. According to some examples, the chessboard 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.

[0231] 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.

[0232] 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 thus 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.

[0233] Conversion or flipping process

[0234] According to some embodiments, such as Figure 11-12As shown, the display module 300 can be configured such 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 display module 300 can be configured such that the checkerboard 110 remains off during the flipping process, regardless of the flipping process.

[0235] According to an alternative embodiment (not shown), the display module 300 may be positioned such that, during the flipping process, the grid display units 310 corresponding to the selected optional grid 110b1, 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 illuminating or displaying the grid 110 with increased intensity compared to the normal illumination state, i.e., the illumination state not during the flipping process, to highlight the grid 110 involved in the flipping process. Additionally or alternatively, during the flipping process, the grid display units 310 corresponding to the remaining illuminated grids 110 (i.e., grids 110 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. "Light-down state" refers to a state where the grid is illuminated or displayed in a less bright or reduced manner compared to the normal illuminated state, i.e., the illuminated state not during the flipping process, so that the grid 110, which is not involved in the flipping process, will not attract the user's attention. More specifically, this is achieved by enhancing the illumination brightness of the grid display units 310 corresponding to the selected optional grid 110b1, at least one associated opponent enabled grid, and at least one associated current enabled grid, even if they are in the brightness enhancement state, and / or by reducing the display brightness of other enabled grids 110a and / or optional grids 110b1 other than the aforementioned selected optional grid 110b1, at least one associated opponent enabled grid, and at least one associated current enabled grid, even if they are in the brightness reduction state.

[0236] These configurations help highlight the dynamic flipping process, making it easy for users to visually identify which squares 110 have been "flipped." This reduces or avoids visual interference from irrelevant enabled squares 110a and irrelevant optional squares 110b1 during the flipping process, enhancing the gaming experience and helping to save power consumption and extend game time.

[0237] Based on some examples, such as Figure 11-12 As shown, the display module 300 can be configured such that during the flipping process, the display units 310 corresponding to the remaining active squares 110a 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 () or dimmed state (not shown), and after the toggling process is complete, it returns from the off state or dimmed state to the original on state and lit state. Figure 13 According to some embodiments, the display module 300 may be configured such that, during the flipping process, the display unit 310 corresponding to the remaining optional squares 110b1 in that game step becomes off. Figure 13 It may be in a dimmed state (not shown) or a reduced brightness state, and it will not return to its original state after the flipping process is completed.

[0238] 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.

[0239] According to some embodiments, the chess device 10 is configured to sequentially convert one 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 display module 300 may be configured such 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 enjoyment. According to some embodiments, the chess device 10 is configured such that the selected square is converted into the current-enabled square before the at least one associated opponent-enabled square. More specifically, the chess device 10 may 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 display module 300 can be configured such that the display unit 310 corresponding to the selected square changes the displayed indication 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.

[0240] 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 display module 300 may be configured such that the square display unit 310 corresponding to the at least one associated opponent-enabled square simultaneously changes the displayed indication 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 may 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 display module 300 may be configured such that the square display unit 310 corresponding to the selected square changes the displayed indication 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 helps to enhance 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 display module 300 can be configured 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.

[0241] 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 L1, L2, L3. Each transition line or flip line L1, L2, L3 sequentially and adjacently includes at least one of the selected, associated opponent-enabled squares, 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 display module 300 may be configured such 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.

[0242] 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-enabled square. Further, the display module 300 may be configured such 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-enabled square. According to an alternative embodiment, the chess-playing device 10 may be configured such that associated opponent-enabled squares on the same transition line are converted to the current player-enabled square one by one sequentially, for example, starting from the square display unit 310 corresponding to the selected square and converting them sequentially to the current player-enabled square. Further, the display module 300 may be configured such 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 converted to the current player-enabled square one by one sequentially. According to some embodiments, the chess-playing device 10 may be configured such that the selected square is converted to the current player-enabled square before all associated opponent-enabled squares. Furthermore, the display module 300 can be configured such that the display unit 310 corresponding to the selected square changes the displayed indication information before the display unit 310 corresponding to the at least one associated opponent-enabled square, so as to indicate that the selected square is converted to the current-enabled square before the at least one associated opponent-enabled square.

[0243] Unit 600 for selecting the placement of pieces

[0244] 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 110 between the enabled squares 110a, or more specifically, no inactive squares 110b. In this case, inactive squares 110b, or more specifically, 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 110a expand from the enabled central area outwards to the outer squares 110 of the chessboard 100.

[0245] According to some embodiments, such as Figure 15-17As shown, the chess-playing device 10 is configured to automatically display all available chess squares 110b1 at the start of each game step, and automatically select one of the available chess squares 110b1 as the currently 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 110 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".

[0246] 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 being capable of moving relative to the fixed part 610 between at least two occupiable positions to select one of the inactive squares 110b, more specifically from all optional 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 a selection sensing signal as described above, when the movable part moves between the at least two occupiable positions. According to one embodiment, the display module 300 is configured to control, based on the selection sensing signal, the square display unit 310 corresponding to the associated inactive square 110b, such as an optional square 110b1, to change state. By way of example, and not exclusively, when the movable part moves from the currently occupies a position to the next occupies a position, the selected square 110c changes from the currently selected square 110c to the next selected square 110c. Simultaneously, the sensing component generates a selection sensing signal. Based on this sensing signal, the display module 300 switches the square display unit 310 corresponding to the currently selected square 110c 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 fixed second sensor and at least one first sensor configured to move with the movable part. The first sensor can sense each other with the corresponding second sensor to generate a selection sensing signal. 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.

[0247] 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.

[0248] 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 110a expand from the active area, such as the central active area, outwards towards the periphery of the active area, until reaching the outer squares 110 of the chessboard 100. In this case, each optional square 110b1 is located on the periphery of at least one active square 110a, so all optional squares 110b1 are positioned around the active square 110a. 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 squares 110 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 square 110a, rather than a strictly circular direction.

[0249] 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 20, with at least a portion of the rotating ring 620 disposed around 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 23 defined by the cylindrical body portion. According to one specific embodiment, the rotating ring 620 is mounted at least partially around the cylindrical body 20. 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 20, more specifically, the checkerboard 100 or cover plate 30 is disposed at that axial end.

[0250] 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.

[0251] 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 configured 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, with the teeth and grooves 624 alternately disposed on the first mating surface 623 such that each groove 624 is disposed between two adjacent teeth in the circumferential direction. 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 in that, 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 vibratory tactile sensation.

[0252] According to some embodiments, such as Figure 19-24As shown, the 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 teeth 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 at the corresponding rotational position.

[0253] 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) and entering a groove 624. According to some embodiments, the leaf spring is configured as a single element. 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.

[0254] According to some embodiments, such as Figure 21-23 As 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, thereby preventing the rotating ring 620 from jamming during rotation and providing a better user experience. 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 described above), the positioning member 613 abuts against the first mating surface 623 to compress the elastic member 612, more specifically, it is 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 rotation position.

[0255] According to an alternative embodiment, contrary to the above embodiment, the second mating part can be configured as a groove 624 on the fixing part 610, and the first mating part 624 is configured to include an elastic member 612 connected to the rotating ring 620 and an optional positioning member 613 connected to the elastic member 612. More specific embodiments can be found in the above embodiments, and will not be repeated here.

[0256] According to some embodiments, such as Figure 19-23 As 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.

[0257] 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.

[0258] According to some embodiments, such as Figure 1-4As 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.

[0259] 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 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.

[0260] 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.

[0261] According to some embodiments, such as Figure 1-4As 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 intuitively 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, and grooves are 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.

[0262] According to some embodiments, the chess device 10 may include a sensing component configured to generate a rotation position sensing signal, i.e., the selection sensing signal, when the rotating ring 620 switches between the plurality of rotation positions. According to some embodiments, the chess device 10 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 display module 300 is configured to switch the state of the square display unit 310 corresponding to the associated inactive square 110b, such as the optional square 110b1, based on the rotation position sensing signal generated by the sensing component. By way of example, but 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. Based on the generation of the rotation position sensing signal, the display module 300 switches the square display unit 310 corresponding to the currently selected square 110c 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 number of first or second sensors may be the same as the number of rotation positions; alternatively, the number of first or second sensors may be different from the number of rotation positions. According to some embodiments, the sensing component is configured to sense the rotation direction of the rotating ring 620 relative to the fixed portion 610.

[0263] According to some embodiments, the sensing component may include an electrical and / or magnetic sensing component, a light and / or color sensing component, etc.

[0264] 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 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 is provided with one magnet 6311 receiving portion.

[0265] In an alternative embodiment, the first sensing element includes a Hall sensor 6321, and the second sensing element includes a plurality of magnets 6311, wherein, exemplary, the number of magnets 6311 is the same as the number of rotational positions.

[0266] 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.

[0267] Advantages and disadvantages module

[0268] 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 110a 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 further embodiments of the first and third variations described above, the advantage / disadvantage indication module can be configured to update the advantage / disadvantage information after each operation of the move placement confirmation units 500 and 700. According to a further embodiment of the second variation described above, the advantage / disadvantage indication module can be configured to update the advantage / disadvantage information when the selection operation of the move placement selection unit 600 satisfies 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 can be configured to provide advantage / disadvantage information in a non-continuous manner.

[0269] 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 comprises multiple indicator light units, referred to herein as "LED beads" 810. The indicator light units exemplarily include LEDs. According to some embodiments, the indicator light assembly 800 can be configured to change at least one of its on / off state, illumination brightness, illumination color, illumination flashing mode, etc. According to some embodiments, the multiple LED beads 810 can be independently controlled relative to each other.

[0270] According to some embodiments, during the game process of the chess device 10, such as Figure 9-18 As shown, the plurality of LEDs 810 includes a first-state LED 811 indicator unit in a first state and a second-state LED 812 indicator unit in a second state, the second state being different from the first state. The indicator assembly 800 can be configured to provide advantage / disadvantage information through at least one of the following: the number of first-state LED 811 indicator units and the number of second-state LED 812 indicator units; the proportion of first-state LED 811 indicator units among the plurality of LEDs 810, and / or the proportion of second-state LED 812 indicator units among the plurality of LEDs 810; the ratio of the area occupied by the first-state LED 811 indicator units to the total area of ​​the indicator assembly 800, and / or the ratio of the area occupied by the second-state LED 812 indicator units to the total area of ​​the indicator assembly 800. More specifically, when using the indicator assembly 800 to provide advantage / disadvantage information, the plurality of LEDs 810 of the indicator assembly 800 are divided into first-state LED 811 indicator units and second-state LED 812 indicator units. According to some embodiments, each of the first and second states manifests as 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 assembly 800 can be divided into first-state LED 811 indicator units and second-state LED 812 indicator units that are not mixed with each other; that is, the first-state LED 811 indicator units are continuously distributed, and the second-state LED 812 indicator units are continuously distributed. More specifically, the indicator assembly 800 is divided into a first segment and a second segment, where the first segment can be a segment where the first-state LED 811 indicator units are distributed, and the second segment can be a segment where the second-state LED 812 indicator units are distributed. This allows the human eye to more intuitively and clearly determine the current advantage or disadvantage of both sides in the game.

[0271] 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. That is, 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 the game process, such as... Figure 9-14 As shown, the indicator light assembly 800 can be configured to alternately illuminate the corresponding first-state LED bead 811 indicator light unit in a first illumination state and a second illumination state between various game steps. The first illumination state and the second illumination state are different from each other. The proportion of the first-state LED bead 811 indicator light unit illuminated in the first illumination state among the plurality of LED beads 810 represents the proportion of the first-party activated grid 110a1 among all activated grids 110a. The proportion of the first-state LED bead 811 indicator light unit illuminated in the second illumination state among the plurality of LED beads 810 represents the proportion of the second-party activated grid 110a2 among all activated grids 110a. Alternatively or additionally, the ratio of the area occupied by the first-state LED 811 indicator unit illuminated in the first lighting state to the total area of ​​the indicator assembly 800 can represent the proportion of the first-side activated chess square 110a1 among all activated chess squares 110a, and the ratio of the area occupied by the first-state LED 811 indicator unit illuminated in the second lighting state to the total area of ​​the indicator assembly 800 can represent the proportion of the second-side activated chess square 110a2 among all activated chess squares 110a. According to some embodiments, the chess device 10 is configured to indicate the player in a corresponding game step through the first lighting state and the second lighting state of the first-state LED 811 indicator unit. More specifically, if the first-state LED 811 indicator unit is currently illuminated in the first lighting state, it indicates that the player in the current game step is the first player; conversely, if the first-state LED 811 indicator unit is currently illuminated in the second lighting 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 indicator unit is lit in a first-lit state, it indicates that the currently activated square is the first-side-activated square 110a1; when the first-state LED 811 indicator unit is lit in a second-lit state, it indicates that the currently activated square is the second-side-activated square 110a2. These embodiments allow the indicator assembly 800 to have the dual function of indicating the advantages and disadvantages 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 9-13The 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 player who plays in the current game step is the purple side. Figure 14 The yellow LED 812 in the first state can be used to indicate the proportion of the yellow (second) player's (second) activated squares in all activated squares 110a, that is, to indicate the yellow player's advantage or disadvantage. On the other hand, it can be used to indicate that the player who plays in the current game step is the yellow player.

[0272] According to some embodiments, such as Figure 9-14 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 9-14 As shown, according to some embodiments, the first activation indication information for indicating the activation of the first grid 110a1 is represented by a first illumination state, such as a first color, and the second activation indication information for indicating the activation of the second 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 corresponding activation grid 110a in all activation grids 110a is consistent with the activation indication information used to indicate the corresponding activation grid 110a. This allows for a very intuitive indication of the proportion of the LED beads 810 illuminated in the corresponding illumination state in all LED beads 810 or the proportion in the total area of ​​the indicator assembly 800 representing the proportion of the corresponding activation grid 110a in all activation grids 110a.

[0273] 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 in the corresponding game move through the first illumination state, more specifically, the first color, and the second illumination state, more specifically, the second color of the first state LED bead 811 indicator unit. For example, if the current first state LED bead 811 indicator unit is illuminated in the first color, it indicates that the player in the current game move is the first player; conversely, if the current first state LED bead 811 indicator unit is illuminated in the second color, it indicates that the player in the current game move is the second player. Simultaneously, the proportion of the current first state LED bead 811 indicator unit in terms of quantity or area among all LED beads 810 is used to represent the current advantage / disadvantage information. Figure 13In 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 13 According to one embodiment, the updated advantage / disadvantage information is presented in the same way as the previous advantage / disadvantage information. For example, if the player in the current game move is the first player, then in the first stage, the advantage / disadvantage information can be represented by the proportion of the number of first-state LED beads 811 indicator units lit in the first color among all LED beads 810; in the second stage, the updated advantage / disadvantage information is still represented by the proportion of the number of first-state LED beads 811 indicator units lit in the first color among the LED beads 810; and vice versa.

[0274] 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 the first activation information, and the square display unit 310 corresponding to the second-side activated square 110a2 displays the second activation information. In addition, at this time, the first state LED bead 811 indicator unit of the advantage / disadvantage indicator module, or more specifically the indicator light assembly 800, is lit in the first color, and the second state LED bead 812 indicator unit is in the off state. The proportion of the number or area of ​​the LED beads 810 lit in the first color in all LED beads 810 indicates the proportion of the first-side activated square 110a1 in all activated squares 110a. According to some embodiments, the first stage may include a display stage for optional squares 110b1 following the initial stage, in which the chess device 10 is configured to display all optional squares 110b1 on the chessboard 100. More specifically, the display module 300 is configured to display optional indication information in the square display unit 310 corresponding to the optional square 110b1. According to one embodiment, the chess device 10 is also configured to automatically select one optional square 110b1 in this stage and display first optional indication information in the square display unit 310 corresponding to the automatically selected optional square 110b1, while display second optional indication information in the square display units 310 corresponding to the remaining optional squares 110b1. According to some embodiments, the first stage may include a square 110 selection stage following the initial stage or 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 can be omitted. More specifically, in this optional square 110b1 selection stage, the move position selection unit 600 can be operated to select one of a plurality of 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.

[0275] 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.

[0276] 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 currently 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 occur simultaneously with the flipping phase and the enabled square 110a layout update display phase, or it can occur after the enabled square 110a layout update display phase. Specifically, the advantage / disadvantage indicator module updates the advantage / disadvantage information and displays the updated 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 activated square 110a to all activated 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 increased.

[0277] 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.

[0278] 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 phase is completed, and thus can automatically switch the display of advantage and disadvantage information. For example, if the player in the current game step is the first player, the advantage and disadvantage indicator module of the current game step indicates the proportion of the number of the first player's activated chess square 110a1 among all activated chess squares 110a by the proportion of the first state LED bead 811 indicator unit lit in the first illuminated state (more specifically, the first color) among all LED beads 810. Then, in the next game step, the player becomes the second player, and the advantage and disadvantage indicator module switches to indicating the proportion of the number of the second player's activated chess square 110a2 among all activated chess squares 110a by the proportion of the number of the second state LED bead 812 indicator unit lit in the second illuminated state (more specifically, the second color) among all LED beads 810.

[0279] 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 a second illuminated state of LED 812 indicator unit. The second illuminated state is different from the first illuminated state. That is, the first state LED 811 indicator unit is LED 810 illuminated in the first illuminated state, and the second state LED 812 indicator unit 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 the first state LED 811 indicator unit among the plurality of LEDs 810 represents the proportion of the first activated checkerboard 110a1 among the activated checkerboard 110a; the proportion of the second state LED 812 indicator unit among the plurality of LEDs 810 represents the proportion of the second activated checkerboard 110a2 among the activated checkerboard 110a. Alternatively or additionally, the ratio of the area occupied by the first-state LED 811 indicator unit to the total area of ​​the indicator 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 indicator unit to the total area of ​​the indicator assembly 800 can represent the proportion of the second-party activated grid 110a2 in the activated grid 110a. According to some embodiments, the chess device 10 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 chess device 10 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 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.

[0280] 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 110a 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 110a.

[0281] According to some embodiments, such as Figure 1-4As shown in Figures 10, 9-18, 24-25, 27, and 30-31, the indicator light assembly 800 is configured to surround the chessboard 100. More specifically, the plurality of LED beads 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 LED beads 810 of the light strip 800 are disposed on the circuit board 410 of the control module 400, located 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.

[0282] 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 bead 811 indicator unit is an LED 810 in an illuminated state, and the second state LED bead 812 indicator unit is an LED 810 in an off state. In some embodiments, such as... Figure 9 , 14As shown in Figure 16, the indicator light assembly 800 is configured such that, during the game, the first state LED bead 811 indicator light unit 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 bead 811 indicator light unit 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 bead 811 indicator light unit 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 when combined with the first state LED bead 811 indicator light unit 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 occupied by the first state LED bead 811 indicator light unit; the lighting state of the first state LED bead 811 indicator light unit (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.

[0283] 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.

[0284] According to alternative embodiments, as described above and as follows Figure 17-18 As shown, during the game, the first-state LED indicator unit 811 is the LED 810 in the first illuminated state, and the second-state LED indicator unit 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 this embodiment, the first-state LED indicator unit 811 can be further configured to always correspond to the first or third position point 13, and the second-state LED indicator unit 812 can always correspond to the second or fourth position point 14.
