Description

A Sudoku game device with instant feedback Technical Field

[0001] This invention relates to the field of children's toys, and more particularly to a Sudoku game device that provides instant feedback. Background Technology

[0002] Sudoku is a placement puzzle, also known as digit puzzle. Typically, the goal of the puzzle is to fill each cell of a grid with a number from 1 to 9. Most commonly, it consists of a 9x9 grid. Sudoku begins with some grid cells filled with numbers (“given”), and each row, column, and area must contain only one instance of that number. Completing a Sudoku game requires patience and logical thinking. Furthermore, Sudoku will exercise the logical aspects of your brain; although the puzzles are quite simple, solving them will certainly give you a challenge. As mentioned above, each row and column contains the number from 1 to 9. Each of the nine 3x3 areas will also contain a number. Based on this specification, and with several cells shown, you can deduce the numbers in the other cells until the entire grid is filled.

[0003] Traditionally, Sudoku games were often played on paper. This involved wasting energy, eyesight, and time by repeatedly checking the numbers on the puzzle pieces. When the puzzle pieces did not meet the requirements, the players would repeatedly try and correct them by erasing, rearranging, and checking the numbers, which would eventually damage the paper and make the game inconvenient.

[0004] Based on this, US Patent Publication No. US20070173314A1 discloses a Sudoku device, including a microprocessor; a Sudoku condition module coupled to the microprocessor, wherein the Sudoku condition module has a Sudoku puzzle program for creating Sudoku puzzles; an input module coupled to the microprocessor, wherein symbols can be input into blank cells on the grid via direction buttons and input buttons of the input module; a display interface coupled to the microprocessor; a display device coupled to the display interface, wherein the display device can display data of Sudoku executed or completed on the display device processed by the microprocessor through the display interface coupled to the display device; and a power supply coupled to the microprocessor and the display interface.

[0005] The above solution does not provide immediate feedback on the correctness of the numbers entered by the user, causing some users to stop playing. Furthermore, users have difficulty distinguishing between the numbers they entered and the given numbers on the display device, making subsequent troubleshooting and verification processes quite difficult.

[0006] Furthermore, the Sudoku devices provided by the above solutions can only offer Sudoku games of a specific difficulty level, and cannot allow users to adjust the appropriate Sudoku difficulty according to their situation. Because the difficulty cannot be adjusted, users may feel that the current Sudoku game is too easy or too difficult, resulting in low adaptability, which needs to be improved. Summary of the Invention

[0007] To address the aforementioned problems, the present invention aims to provide a Sudoku game device with real-time feedback. This device can instantly determine the correctness of the values ​​entered by the user and provide immediate feedback, thereby facilitating further progress in Sudoku games and making it suitable for children in the process of developing Sudoku skills.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A Sudoku game device with instant feedback, characterized in that it includes a housing, and a microprocessor, a Sudoku puzzle library module, a display device, and an instruction input module built into the housing; the microprocessor is coupled to the Sudoku puzzle library module, the display device, and the instruction input module respectively; the Sudoku puzzle library module is used to store or create Sudoku puzzles, and the matrix distribution of number combinations in the Sudoku puzzles is divided into public default numbers and unpublished hidden numbers; the display device is matrix-divided into multiple display units arranged in a grid, each capable of independently displaying number symbols; the microprocessor retrieves Sudoku puzzles from the Sudoku puzzle library module and displays the default numbers on the display device based on the matrix correspondence; the instruction input module includes directional keys for planar displacement on the display units and input keys for entering number symbols into the display units; characterized in that the microprocessor can compare the number symbol entered into the selected display unit with the corresponding hidden number in the Sudoku puzzle, and display the comparison result based on the display unit.

[0010] The present invention adopts the above-mentioned technical solution, which relates to a Sudoku game device with real-time feedback. The basic execution principle of the Sudoku game device can be referred to the technical solution described in the background art. The Sudoku puzzle bank module is used to store or create Sudoku puzzles. Storage means that it is stored in the hard disk as a memory file and can be retrieved by the corresponding instruction. Creation means that when no Sudoku puzzles are stored, the Sudoku puzzle bank module randomly generates the corresponding Sudoku puzzles based on Sudoku rules.

[0011] Whether retrieving a stored Sudoku puzzle or creating a generated Sudoku puzzle, the number combinations distributed in the matrix of a Sudoku puzzle are divided into public default numbers and unpublished hidden numbers. Public default numbers are those that are already given in the matrix of the Sudoku game and do not need to be filled in by the user. Unpublished hidden numbers refer to the correct values ​​that the user needs to fill in in the Sudoku matrix.

[0012] When the device starts up, the microprocessor retrieves Sudoku puzzles from the Sudoku puzzle library module and displays default numbers on the display device based on matrix correspondence. Then, the user is prompted to fill in the corresponding numbers in the remaining display cells. The user can use the arrow keys to move the cursor up, down, left, and right to adjust to the desired display cell; the input keys are used to input specific numbers into the selected display cell after the cursor is moved, and can be the number keys from "0" to "9".

[0013] Building upon this foundation, the Sudoku device provides instant feedback. The microprocessor compares the number entered by the user with a hidden number in the puzzle bank for that position, thus determining if the user's input is correct. The comparison result is then displayed on a separate indicator light or by the flashing of numbers on the display unit. This structure allows for real-time judgment of the user's input, providing immediate feedback and facilitating further progress in the Sudoku game. It is suitable for children developing Sudoku skills.

[0014] In a specific implementation, the microprocessor converts the numerical symbols presented in the selected display unit into digital signals and compares them with the corresponding hidden numbers in the Sudoku puzzle. This approach involves the microprocessor determining the combination of digital signals in the current display unit by analyzing the pin signals of its pins or the pin signals of the sub-control units connected to it, thereby determining whether the currently input number corresponds to the correct stored number in the display unit.

[0015] Preferably, the display unit includes seven LEDs arranged in a figure-eight pattern, with each of the seven LEDs connected to a pin of the sub-control unit. In this configuration, the arrangement of the seven LEDs allows the display of numbers "0" through "9".

[0016] Preferably, the microprocessor is also connected to multiple sub-control units, and the multiple display units divided by the matrix are divided into multiple groups, with each sub-control unit connected to and controlling one of the groups of display units. In this scheme, the microprocessor acts as the main control unit, controlling the multiple display units arranged in the matrix through the sub-control units.

[0017] Preferably, a timing unit is also included, which comprises multiple display units capable of independently displaying numerical symbols; one of the sub-control units connects to and controls the multiple display units of the timing unit. In this solution, the timing unit can keep track of the time taken during the Sudoku game, allowing the user to understand the duration of the Sudoku puzzle.

[0018] Preferably, each display unit also includes a marker light to indicate whether the display unit is a display grid for displaying default numbers or a blank grid for inputting numbers. In this scheme, the marker light can be used to indicate whether the number displayed in the display unit is a default number or a number entered by the user; this facilitates the user's review and verification of the entered numbers. The marker light can be lit when the display unit is being used, or it can be lit when the blank unit is being used.

[0019] Preferably, the instruction input module includes directional keys for planar displacement on the display unit and input keys for entering numerical symbols into the display unit. In this scheme, the directional keys move the cursor up, down, left, and right to adjust it to the desired display unit; the input keys are used to input specific numbers into the selected display unit after the cursor has moved, and can be number keys from "0" to "9". In a further preferred scheme, the input keys include a first input key for increasing the input value and a second input key for decreasing the input value. These two keys are used to increase or decrease the value in the specific display unit to ultimately fill in the desired value. Compared to using 10 number keys, this scheme is structurally simpler.

[0020] Preferably, the Sudoku puzzle library module includes multiple advanced puzzle libraries to store Sudoku puzzles with different matrix counts. It also includes an advanced control unit, which switches the number of display unit matrices controlled by the microprocessor and selects appropriate Sudoku puzzles from the corresponding advanced puzzle library within the Sudoku puzzle library module. Specifically, the Sudoku puzzle library module in this solution is divided into multiple advanced puzzle libraries (sub-libraries) to store Sudoku puzzles with different matrix counts. For example, sub-library one stores 4x4 Sudoku puzzles, sub-library two stores 6x6 Sudoku puzzles, and sub-library three stores 9x9 Sudoku puzzles. Furthermore, the advanced control unit in this device controls the microprocessor to select Sudoku puzzles from one of the advanced puzzle libraries in the Sudoku puzzle library module and also adjusts the number of display unit matrices that the microprocessor can control.

[0021] In this way, users can adjust the number of Sudoku puzzles in the appropriate matrix based on the advanced control unit, select Sudoku puzzles suitable for their current cognitive ability, and further achieve progressive Sudoku practice based on the increase in proficiency and cognition; gradually cultivating children's interest and ability in solving Sudoku puzzles. Therefore, this device is suitable for users with different cognitive levels, and has a higher degree of compatibility.

[0022] In this specific solution, the microprocessor matrix controls multiple display units. The advanced control unit is constructed as an advanced control switch coupled to the microprocessor. The advanced control switch includes multiple switch branches connected to multiple pins of the microprocessor, and is used to control the activation of one of the microprocessor's pins. In this solution, the microprocessor uses a matrix to control multiple display units. Matrix control is a common control method in circuit control, capable of controlling the execution of terminal electrical components distributed in a matrix. Since this is not an innovation of this case, it will not be described in detail. This solution connects multiple switch branches of the advanced control switch to several pins of the microprocessor. Operating the advanced control switch allows selection of one switch branch to be activated, thereby adjusting the advanced question bank activated by the microprocessor and the display units it can control.

[0023] In an alternative embodiment, the device is equipped with multiple display devices, each configured as a display unit with a different matrix number; the display devices are detachably connected to the housing and coupled to the microprocessor.

[0024] The Sudoku puzzle bank module contains multiple advanced puzzle banks to store Sudoku puzzles with different matrix sizes. The microprocessor retrieves Sudoku puzzles compatible with the specifications of the equipped display device from the corresponding advanced puzzle bank in the Sudoku puzzle bank module. In this solution, the Sudoku puzzle bank module is specifically divided into multiple advanced puzzle banks (sub-puzzles), which are used to store Sudoku puzzles with different matrix sizes. For example, sub-puzzle bank one stores 4*4 Sudoku puzzles, sub-puzzle bank two stores 6*6 Sudoku puzzles, and sub-puzzle bank three stores 9*9 Sudoku puzzles. Furthermore, the device is equipped with various display devices of different specifications. Users can select a suitable display device according to the required Sudoku difficulty, and the microprocessor can select puzzles from the advanced puzzle bank corresponding to the currently equipped display device through detection or manual reset to ensure the accuracy of the display.

[0025] In the specific design, a groove is provided on the surface of the housing, and a first terminal is constructed on the side wall of the groove. The display device is detachably embedded in the groove and coupled to the first terminal through a second terminal. Attached Figure Description

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0040] As shown in Figures 1-9, this embodiment relates to a Sudoku game device, including a housing 1, and a microprocessor 2, a Sudoku puzzle library module, a display device 3, and an instruction input module built into the housing 1. The microprocessor 2 is coupled to the Sudoku puzzle library module, the display device 3, and the instruction input module. The Sudoku puzzle library module is used to store or create Sudoku puzzles. The matrix distribution of numbers in the Sudoku puzzles is divided into public default numbers and undisclosed hidden numbers. The display device 3 is matrix-divided into multiple display units 31 arranged in a grid, each capable of independently displaying number symbols. The microprocessor 2 retrieves Sudoku puzzles from the Sudoku puzzle library module and displays the default numbers on the display device 3 based on the matrix correspondence.

[0041] The basic operating principle of this Sudoku game device can be found in the technical solutions described in the background section. The Sudoku puzzle library module is used to store or create Sudoku puzzles. Storage refers to storing the puzzles as memory files on the hard drive, which can be retrieved by corresponding instructions. Creation refers to the Sudoku puzzle library module randomly generating corresponding Sudoku puzzles based on Sudoku rules when no puzzles are stored. Whether retrieving stored puzzles or creating generated puzzles, the number combinations distributed in the matrix of a Sudoku puzzle are divided into public default numbers and hidden numbers. Public default numbers refer to the numbers already given in the matrix cells of the Sudoku game and do not require user input. Hidden numbers refer to the correct values ​​that the user needs to fill in within the Sudoku matrix. When the device starts, the microprocessor 2 retrieves the Sudoku puzzles from the Sudoku puzzle library module, displays the default numbers on the display device 3 based on the matrix correspondence, and then prompts the user to fill in the corresponding numbers in the remaining display units 31.

[0042] In a specific implementation, the microprocessor 2 controls multiple display units 31 in a matrix. As shown in Figure 4, the microprocessor 2 is also connected to multiple sub-control units 4. The multiple display units 31 divided by the matrix are divided into multiple groups, and each sub-control unit 4 is connected to and controls one of the groups of display units 31. In this scheme, the microprocessor 2 is used as the main control unit, and the sub-control units 4 control the multiple display units 31 arranged in the matrix. The main control chip shown in the figure is the microprocessor 2. There are 6 sub-control units 4, namely sub-control chips U1, U2, U3, U4, U5 and U6. In the scheme shown in the figure, the display device 3 is constructed as 9*9 display units 31 to satisfy a Sudoku puzzle with a maximum size of 9*9. Based on the circuit connection shown in the figure, the sub-control chip U1 is used to control display units 31 numbered 1-15, the sub-control chip U2 is used to control display units 31 numbered 16-30, the sub-control chip U3 is used to control display units 31 numbered 31-45, the sub-control chip U4 is used to control display units 31 numbered 46-60, the sub-control chip U5 is used to control display units 31 numbered 61-75, and the sub-control chip U6 is used to control display units 31 numbered 76-81.

[0043] In a further preferred embodiment, the microprocessor 2 can compare the number symbol entered into the selected display unit 31 with the corresponding hidden number in the Sudoku puzzle, and display the comparison result based on the display unit 31. This Sudoku device can provide instant comparison feedback; that is, the microprocessor 2 can compare whether the number entered by the user matches the hidden number not displayed at that position in the puzzle bank, thereby determining whether the user's input is correct. The comparison result is then displayed through the display unit 31. This display can be achieved by setting a separate indicator light to indicate correctness, or by flashing the numbers displayed on the display unit 31. Based on this structure, the correctness of the user's input can be judged instantly, providing immediate feedback to the user, thus facilitating further progress in the Sudoku game and making it suitable for children in the process of developing Sudoku skills. In a specific implementation, the microprocessor 2 converts the number symbol displayed in the selected display unit 31 into a digital signal and compares it with the corresponding hidden number in the Sudoku puzzle. This solution uses the microprocessor 2 to determine the current combination of digital signals in the display unit 31 by judging the pin signals of its pins or the pin signals of the connected sub-control unit 4, thereby determining whether the currently input number corresponds to the correct stored number in the display unit 31.

[0044] In a further preferred embodiment shown in Figure 8, a timing unit 5 is also included, which further comprises multiple display units 31 capable of independently displaying numerical symbols. One sub-control unit 4 connects to and controls the multiple display units 31 of the timing unit 5. In this embodiment, the timing unit 5 can keep track of time during the Sudoku game, allowing the user to understand the duration of the Sudoku puzzle. In this embodiment, the timing unit 5 uses six display units 31, each representing XX:XX:XX, hours / minutes / seconds. All six display units 31 of the timing unit 5 are controlled and connected by a sub-control chip U6 and are displayed through a window 11 on the housing 1.

[0045] As shown in Figure 6, the display unit 31 includes seven LEDs 32 arranged in a figure-eight pattern, each connected to a pin of the sub-control unit 4. This is existing technology, commonly found in various digital signage (such as elevator floor displays). Based on the arrangement of the seven LEDs 32, it can display the numbers "0" to "9". In the figure, this refers to DA1, DB1, DC1, DD1, DE1, DF1, and DG1, these seven LEDs 32 arranged in a figure-eight pattern. In a further embodiment shown in the figure, each display unit 31 also includes a marker light 33, represented by DP1 in the figure, located at the lower right corner of the figure-eight arrangement. This marker light indicates whether the display unit 31 is used to display default numbers or is a blank unit for inputting numbers. In this embodiment, the marker light 33 can be used to indicate whether the number displayed in the display unit 31 is a default number or a number entered by the user. This facilitates the user's viewing and verification of the entered numbers. The marker light 33 here can be lit when it is still representing the display unit 31, or it can be lit when it is representing a blank unit.

[0046] In the schemes shown in Figures 1, 2, and 9, the instruction input module includes directional keys 71 for planar displacement on the display unit 31, and input keys for entering numerical symbols into the display unit 31. In this scheme, operating the directional keys 71 drives the cursor to move up, down, left, and right, thereby adjusting to the desired display unit 31. The input keys are mainly used to input specific numbers into the selected display unit 31 after the cursor is moved; these can be number keys from "0" to "9". Further, the input keys include a first input key 72 for increasing the input value and a second input key 73 for decreasing the input value. By using these two keys to increase or decrease the value in the specific display unit 31, the final value is entered. In comparison, this scheme is structurally simpler than using 10 number keys.

[0047] In the first embodiment shown in Figures 3 and 7, the Sudoku puzzle bank module contains multiple advanced puzzle banks for storing Sudoku puzzles with different matrix counts. It also includes an advanced control unit 6, which switches the number of matrices in the display unit 31 controlled by the microprocessor 2, and switches the microprocessor 2 to retrieve Sudoku puzzles of appropriate specifications from the corresponding advanced puzzle bank in the Sudoku puzzle bank module. Based on the above-mentioned prior art, the Sudoku puzzle bank module in this solution is specifically divided into multiple advanced puzzle banks (sub-puzzle banks), which are used to store Sudoku puzzles with different matrix counts. In this embodiment, three different difficulty levels are set, including three advanced puzzle banks. Sub-puzzle bank one is used to store 4*4 Sudoku puzzles, sub-puzzle bank two is used to store 6*6 Sudoku puzzles, and sub-puzzle bank three is used to store 9*9 Sudoku puzzles. The advanced control unit 6 in the device is used to control the microprocessor 2 to retrieve Sudoku puzzles from one of the advanced puzzle banks in the Sudoku puzzle bank module, and can also adjust the number of display unit matrices that the microprocessor 2 can control.

[0048] In this way, users can adjust the number of Sudoku puzzles in the appropriate matrix using the advanced control unit 6, selecting puzzles suitable for their current cognitive abilities. Furthermore, based on their increased proficiency and cognitive abilities, they can achieve progressive Sudoku practice, gradually cultivating children's interest and ability in solving Sudoku puzzles. Therefore, this device is suitable for users of different cognitive levels, offering greater adaptability.

[0049] In a specific implementation, the advanced control unit 6 is constructed as an advanced control switch coupled to the microprocessor 2. The advanced control switch includes three switch branches connected to multiple pins of the microprocessor 2, namely SW1, SW2, and SW3, which are used to connect to pins 33, 34, and 35 of the microprocessor 2, respectively. Sub-branch one is used to connect to switch branch SW1, sub-branch two is used to connect to switch branch SW2, and sub-branch three is used to connect to switch branch SW3. The aforementioned advanced control switch is used to control the activation of one of the pins of the microprocessor 2. In this scheme, the microprocessor 2 uses matrix control to control multiple display units 31. Matrix control is a common control method in circuit control, that is, a control method that can control the execution of terminal electrical components distributed in a matrix. Since it is not an innovative point of this case, it will not be described in detail. This solution connects three switch branches of the advanced control switch to some of the pins of the microprocessor 2. By operating the advanced control switch, one of the switch branches can be turned on, thereby adjusting the advanced question bank turned on by the microprocessor 2 and the display unit 31 that can be controlled.

[0050] The advanced control switch can be configured as an analog switch input via a touch signal. More preferably, the advanced control switch is constructed as a physical switch 12 mounted on the housing 1 and capable of physical operation. Using a physical switch 12 for adjustment simplifies user operation and adjustment, making it particularly suitable for students for whom this device is intended.

[0051] In another alternative embodiment shown in Figure 9, the device is equipped with multiple display devices 3, each configured as a display unit 31 with a different number of matrices. The display devices 3 are detachably connected to the housing 1 and coupled to the microprocessor 2. The Sudoku puzzle library module contains multiple advanced puzzle libraries for storing Sudoku puzzles with different numbers of matrices. The microprocessor 2 retrieves Sudoku puzzles compatible with the specifications of the assembled display device 3 from the corresponding advanced puzzle library in the Sudoku puzzle library module. In this embodiment, the Sudoku puzzle library module is specifically divided into multiple advanced puzzle libraries (sub-puzzle libraries), which are used to store Sudoku puzzles with different numbers of matrices. For example, sub-puzzle library one stores 4*4 Sudoku puzzles, sub-puzzle library two stores 6*6 Sudoku puzzles, and sub-puzzle library three stores 9*9 Sudoku puzzles. Furthermore, the device is equipped with display devices 3 in various specifications, allowing users to select the appropriate display device 3 based on the required Sudoku difficulty. The microprocessor 2 can select questions from the advanced question bank corresponding to the currently equipped display device 3 through detection or manual resetting to ensure the accuracy of the display. In a specific design, a groove 13 is provided on the surface of the housing 1, and a first terminal is constructed on the side wall of the groove 13. The display device 3 is detachably embedded inside the groove 13 and coupled to the first terminal through a second terminal 30.
