Description

Puzzle game operating device using Sudoku and its operating method {DEVICE AND METHOD FOR OPERATING PUZZLE GAME BASED ON SUDOKU}

The present invention relates to an apparatus for operating a puzzle game applying Sudoku and a method of operating the same, and more particularly, a method of arranging 9 different symbols in three matrices having 3 rows and 3 columns, and the arrangement of symbols is completed. The present invention relates to an apparatus for operating a puzzle game using Sudoku, which implements a method of capturing specific symbols according to the difficulty of the case, and a method of operating the same.

Among the puzzle games using numbers, the most widely spread puzzle game to the public is sudoku. Sudoku is known to have been created by the American architect Howard Garns in 1979, based on the Latin anti-vibration created by the 18th century Swiss mathematician Leonhard Euler. Since the mid-1980s, it is widely known around Japan, and the current form of Sudoku has become popular.

Since Sudoku can be solved using only simple numbers, it is not only used for the hobby of the general public or for temporarily relieving stress, but is also widely spread to students and the elderly because it is known to be good for improving students' mathematical skills and preventing dementia of the elderly. .

The most widely known form of Sudoku is a stack of 9 square matrices of 3 rows and 3 columns. When filling in the blanks of this type of Sudoku problem, the numbers 1 to 9 must be used only once in each of the 9 matrices, and the numbers 1 to 9 must also be used in each row and column of the total 9 rows and 9 columns. It should be used only once.

In addition, there are more complex and various types of Sudoku problems. The representative of a complex sudoku is called a samurai sudoku, and it has a form in which 5 matrices of 9 rows and 9 columns are overlapped in an'X' shape.

However, these complex sudokus are difficult for infants or seniors who are inexperienced to deal with numbers. "Animal Sudoku" has also been developed for infants, but since it is for infants, it consists of 4 matrices of 2 rows and 2 columns (total of 16 cells) or 4 matrices of 3 rows and 3 columns (total of 36 cells), so it is too simple. There is a drawback that can be easily demonstrated.

On the other hand, since 9 square matrices of 3 rows and 3 columns are stacked (total of 81 cells) are square, the aspect ratio of horizontal to vertical is gradually increasing in mobile devices and video output devices that are popular in recent years, and is released in a rectangular form. It is not suitable for the trend of becoming. In addition, since it is necessary to apply a complex algorithm in order to solve a general Sudoku problem, a high-performance semiconductor device must perform many calculations in order to quickly solve a problem, so heat generation and battery consumption also become a problem.

Accordingly, there is a need for a new method and apparatus for operating a puzzle game that is optimized for a rectangular screen and can be operated with a simple algorithm, so that a low-performance device can be used, and that a puzzle game user does not lose interest.

In Patent Publication No. 10-1111451, "A method for generating a Sudoku problem, a method for inspecting a Sudoku problem, and an apparatus for generating a Sudoku problem, and a recording medium thereof", a plurality of cells are added by adding a constant according to the expansion conversion equation to each cell of the basic submatrix according to the Sudoku rule. Generating submatrices, combining a plurality of submatrices to generate an extension matrix, and until the generated extension matrix has a unique solution according to the Sudoku rule, at least one of the cells of the extension matrix is added to the Sudoku rule. Disclosed is a method for generating a Sudoku problem, including the step of generating a Sudoku matrix by adding or deleting the following hints. However, there is a problem of generating an extension matrix using a complex equation.

The same reference numbers throughout the specification indicate the same elements. Meanwhile, terms used in the present specification are for describing exemplary embodiments and are not intended to limit the present invention. In this specification, the singular form also includes the plural form unless specifically stated in the phrase. As used herein, "comprises" and/or "comprising" refers to the presence of one or more other components, steps, actions and/or elements in which the recited component, step, operation and/or element is Or does not preclude additions.

Hereinafter, an apparatus for operating a puzzle game using Sudoku according to an embodiment of the present invention and a method for operating the same will be described in detail with reference to the drawings.

1 is a block diagram showing a schematic configuration of an apparatus for operating a puzzle game using Sudoku according to an embodiment of the present invention.

The puzzle game operating apparatus 100 applying Sudoku includes an input unit 110, a difficulty setting module 120, a symbol capture unit 130, a question questionnaire 140, an answer check unit 150, and a time recording module 160 ), a ranking evaluation module 170, and an output unit 180.

The input unit 110 receives an input from a user for a puzzle game operation. The input unit may use not only a touch screen, a digitizer, a mouse, a keyboard, and a joystick, but also any device that can recognize a user's motion, convert it into an electrical signal, and transmit it to the puzzle game operating device, such as a non-contact motion recognition device. Items received from the user in the input unit include a difficulty level selected by the user, blank information, and a symbol to be inserted in the blank.

The difficulty level setting module 120 stores the level of difficulty input by the user, so that it can be used in a symbol capture unit, a questionnaire questionnaire, and an answer check unit. 'Difficulty' can be classified as easy (lower), normal (medium), difficult (upper), and the concept of'level' such as 1st level, 2nd level, 3rd level, etc. can be used.

The symbol capture unit 130 determines a target symbol set, which is a target of the puzzle game, and stores the captured symbol. The set of target symbols can be set differently depending on the difficulty level. The apparatus 100 for operating a puzzle game applying Sudoku according to an embodiment of the present invention is different from a conventional Sudoku puzzle in which 9 matrices of 3 rows and 3 columns are combined, and only 3 matrices of 3 rows and 3 columns are combined. Even unfamiliar people can easily enjoy it. On the other hand, it is possible to induce interest of puzzle game participants by adding a symbol capture step instead of having fewer combined matrices compared to the usual Sudoku puzzle.

The question questionnaire 140 generates a question matrix to which Sudoku is applied and transmits it to the output unit. At this time, the number of blanks in the problem matrix can be adjusted according to the difficulty level. Unlike a conventional Sudoku puzzle in which 9 matrices of 3 rows and 3 columns are combined, the apparatus 100 for operating a puzzle game applying Sudoku according to an exemplary embodiment of the present invention combines only 3 matrices of 3 rows and 3 columns. Since the puzzle problem matrix can be formed by calculation, a microprocessor with low performance can be used, thereby reducing equipment manufacturing cost or reducing battery consumption in portable devices.

The answer check unit 150 receives the user's input from the input unit, checks whether an appropriate symbol is input, and transmits the result to the output unit.

The time recording module 160 records the time the user has played the puzzle game. The user's play time can be recorded by recording the matrix output time of outputting the Sudoku-applied problem matrix on the screen and the input end time when the user solves the problem matrix and fills all the blanks in the problem matrix.

The ranking evaluation module 170 evaluates the ranking among users who have played the game by using the user's puzzle game play time recorded in the time recording module. When all the symbols in the target symbol set are captured, each matrix problem solving time is calculated at each matrix output time and input end time, and each matrix problem solving time is accumulated to the total game completion time required to complete the game. It is reflected and saved, and the ranking can be evaluated according to the total game completion time.

The output unit 180 outputs a problem matrix of a puzzle game with blanks to the user, outputs whether or not a symbol input by the user is suitable for the blanks in the problem matrix, outputs captured symbols, or displays all of the target symbol sets. If the symbol is captured, it outputs that the game is complete. The output unit can be used not only a monitor composed of LED, LCD, CRT, PDP, OLED, etc., but also any device that can be visually recognized by being able to output to a screen or screen such as a beam projector.

Difficulty setting module between the input unit 110 and the output unit 180, a symbol capture unit, a question questionnaire, an answer check unit, a time recording module, a ranking evaluation module, etc. are implemented in a control unit using one or more semiconductor elements such as a microprocessor. Can be. In addition, each module between the input unit 110 and the output unit 180 is implemented as a module of a program to be implemented by being stored in a storage area of the microprocessor, semiconductor devices such as memory connected to the microprocessor, and storage devices such as HDD. I can.

2 is a block diagram showing a specific configuration of a puzzle game operating apparatus applying Sudoku according to an embodiment of the present invention.

The puzzle game operating apparatus 100 applying Sudoku operates a puzzle game using nine different symbols. Nine different symbols may use “numbers” from 1 to 9, but nine different “symbols” can be used to make it easier for children or elderly people who are not familiar with numbers to enjoy the puzzle game.

The nine different "symbols" can be numbers, figures, moving pictures, vibrations, or sounds.

For example, "number" can be any number from 1 to 9. As "shape", you can select and use 9 pictures or pictures of triangles, squares, stars, moon, sun, snowman, Daboto, Eiffel Tower, bridge, buildings, animals, plants, etc. The "moving picture" can be implemented not only by the moving image of the previous "shape", but also by expressing the number of sparkling stars differently among the nine stars.

In order to output nine different "symbols" using vibration, the number or length of vibration can be expressed differently. In order to output nine different "symbols" using sound, not only the number and length of the sound, but also the frequency (high and low) can be expressed differently. In the case of using vibration or sound, the visually impaired can easily enjoy the puzzle game, and there is an effect that the general person can enjoy the puzzle game with a different or higher difficulty level.

The nine different "symbols" can also be used in combination of these various "symbols" forms. That is, 9 different symbols can be selected by mixing 4 numbers and 5 figures, or 9 different symbols can be selected and used by mixing figures and sounds.

2 shows an embodiment of the present invention showing a specific module constituting the symbol capture unit 130, the question questioning unit 140, and the answer check unit 150. The symbol capture unit 130 may include a target preference setting module 233 and a capture symbol storage module 235, and the question questionnaire 140 is an answer matrix generation module 243 and a question matrix generation module 245 May include, and the answer check unit 150 may include a suitability preference determination module 253 and a capture preference determination module 255.

Each module of FIG. 2 may be implemented to operate independently. Accordingly, in another embodiment of the present invention, each module may be configured independently, or some modules may be disposed in a different position from that of FIG. 2 to be implemented. That is, the capture symbol storage module 235 may be configured to be located in the answer check unit 150.

The target preference setting module 233 determines the number of target symbols according to the difficulty level, and determines a target symbol set according to the number of target symbols. For example, if the difficulty is easy or 1 level, the number of target symbols can be set to 1, if the difficulty is normal or 5 level, the number of target symbols can be set to 5, and if the difficulty is difficult or 9 level The number of target symbols can be set to nine.

In order to set the target symbol set, the target symbol setting module 233 first randomly selects one symbol from nine different symbols and stores it in the target symbol set. Next, the number of symbols stored in the target symbol set is checked, and if it is less than the target number of symbols, an additional arbitrary symbol is additionally selected from among nine different symbols. At this time, only if the randomly selected symbol is not already in the target symbol set, the randomly selected symbol is added to the target symbol set and stored. When randomly selecting additional symbols, it is also possible to use a method of selecting from symbols that do not belong to the set of target symbols. The above process is repeated until the number of symbols of the target symbol set equals the number of target symbols to obtain a target symbol set.

The answer matrix generation module 243 places nine different symbols in the first matrix, the second matrix, and the third matrix, which are three matrices having three columns and three rows, but in the same row and the same column of the three matrices. Create an answer matrix so that only one of nine different symbols is placed. Specifically, since the first matrix has 3 columns and 3 rows, there are 9 blanks. You can place 9 different symbols in each of these 9 blanks. If 9 different symbols are respectively arranged in the second matrix and the third matrix, each of the first to third matrices has 9 different symbols.

On the other hand, the same symbols are not overlapped in one row of the first matrix, one row of the second matrix, and one row of the third matrix. If the symbols are not arranged in the same row in the same way for the second and third rows of the first to third matrices, only one different symbol can be placed in the same row. In the same way, only one different symbol can be arranged for the same column of three matrices.

In the answer matrix, the first to third matrices may be arranged horizontally or vertically. Since the first to third matrices have only one different symbol in each row and column, even if they are arranged horizontally or vertically, all answer matrices have nine different symbols in the same row and column. Can only be placed.

The problem matrix generation module 245 determines a target number of blanks according to the difficulty level, and generates a question matrix having blanks by deleting symbols of some cells of the answer matrix according to the target number of blanks. The generated problem matrix may be transmitted to the output unit 180 and output to the screen.

When setting blanks, it is desirable to set the blanks to include symbols that should be captured. For this, first, one symbol that has not yet been captured is randomly selected from the target symbol set. The selected symbol is set as a blank space in the answer matrix, so that the symbol can be captured while solving the puzzle game. Next, a problem matrix is created by additionally setting random blanks in the answer matrix as many as the number of target blanks determined according to the difficulty level.

The suitable symbol determination module 253 receives the location and symbol of the blank selected by the user from the input unit, and determines whether the input symbol is a symbol suitable for the selected blank. If the input symbol is a symbol suitable for the selected blank, the position of the selected blank and the input symbol are stored in order in the symbol storage matrix.

The capture symbol determination module 255 selects one symbol from the symbol storage matrix as the captured symbol when all blanks in the problem matrix are filled, that is, when the number of symbols in the symbol storage matrix is equal to the target number of blanks.

The capture preference determination module 255 may capture other preferences according to the difficulty level. For example, if the difficulty is easy, the symbol stored at the end of the symbol storage matrix is selected as the captured symbol, and if the difficulty is normal, the symbol stored in the middle of the symbol storage matrix is selected as the captured symbol. In this case, it is possible to select an arbitrary symbol as the captured symbol among the symbols stored in the symbol storage matrix.

As another example, when the difficulty level is 1, the symbol stored at the end of the symbol storage matrix is selected as the captured symbol, and when the difficulty level is 2, the symbol stored second from the end of the symbol storage matrix is selected as the captured symbol. , When the difficulty level is 3, a symbol located in a position proportional to the difficulty level or level may be selected as the captured symbol, such as selecting the symbol stored third from the end of the symbol storage matrix as the captured symbol.

The puzzle game operating apparatus 100 applying Sudoku may further include a control unit (not shown). The control unit controls to receive additional input from the input unit when all the blanks in the question matrix are not filled, or generates an additional answer matrix in the answer matrix generation module when all blanks in the question matrix are filled and all symbols in the target symbol set are not captured. Control to be performed, or control to output that the game is complete when all symbols in the target symbol set are captured, and the like can be performed. The control unit may be configured as a separate element or device, but may be configured as a part of an input unit, an answer matrix generation module, and an output unit by dividing each operation.

Hereinafter, an embodiment of the present invention using animal pictures with nine different symbols will be described. As for the nine different symbols, pictures of'rabbit, turtle, pigeon, donkey, goat, snake, snail, cat, dog' were arbitrarily selected, but the same explanation would be possible for combinations of other symbols.

3 is an exemplary view showing an output unit screen arrangement of a puzzle game operating apparatus to which Sudoku is applied according to an embodiment of the present invention.

The output unit screen 300 includes an input symbol display unit 330, a problem matrix display unit 350, and a capture symbol display unit 370.

The input symbol display unit 330 may display nine different animal picture symbols that can be used in blanks in the problem matrix as an example. Referring to FIG. 3, pictures of'rabbit, turtle, pigeon, donkey, goat, snake, snail, cat, and dog' are displayed with nine different symbols. These input symbols may not be displayed separately, and may be displayed around the blanks when a blank is selected.

The problem matrix display unit 350 displays the problem matrix. Referring to FIG. 3, a problem matrix in which three matrices having three rows and three columns are arranged vertically is displayed. In the problem matrix display unit 350, blanks are indicated by shades on the background, but may be displayed as separate borders or the like.

The capture symbol display unit 370 may display a target symbol set to be captured and the captured symbol. Referring to the capture symbol display unit 370 of FIG. 3, a rabbit, a turtle, and a snail are set as target animal symbols to be captured. The background of the target symbol to be captured can be shaded, and the captured animal symbol can be displayed by deleting the shade. An additional mark such as an'O' may be added to the symbol of the captured animal.

4 is a schematic diagram illustrating a process of generating an answer matrix in a puzzle game operating apparatus applying Sudoku according to an embodiment of the present invention as a matrix.

The answer matrix is a matrix filled with all blanks in the question matrix. In an embodiment of the present invention, after creating an answer matrix, a question matrix is created by setting blank spaces. In the case of using this method, since it is not necessary to create a problem matrix by complex calculations such as Sudoku, it is possible to quickly create a problem matrix with a simple operation.Therefore, it is not necessary to have high performance such as a microprocessor, so that a device can be manufactured at a low price. .

Referring to FIG. 4A, the answer matrix includes a first matrix 451, a second matrix 452, and a third matrix 453 horizontally.

First, one matrix having cells in which symbols are not arranged is selected from the first matrix to the third matrix. 4(a) shows a case where the first matrix 451 is selected.

Next, one cell in which symbols are not arranged is selected from the selected first matrix. You can select from 1st row and 1st column. First, a set consisting of nine different animal symbols is set as a set of selectable symbols. And there are no symbols arranged in the selected first matrix yet.

Since no symbols have been placed in the same'row 1'as the cell selected in the first matrix to the third matrix, and no symbols have been placed in the same'column 1'as the cells selected in the first matrix to the third matrix, so select No symbols are excluded from the set of possible symbols. In the end, since the set of selectable symbols becomes nine different animal symbols, an arbitrary animal symbol is selected from among them. Referring to FIG. 4A, a case where'rabbit' is selected at the positions of 1st row and 1st column of the first matrix 451 is illustrated.

Since there are cells in which symbols are not arranged in the selected first matrix, 1 row and 2 columns are selected as the next cell. First, a set consisting of nine different animal symbols is set as a set of selectable symbols. In addition, since the symbol arranged in the selected first matrix includes'rabbit','rabbit' is excluded from the set of selectable symbols.

Since the'rabbit' is arranged in the same'row 1'as the cell selected in the first matrix to the third matrix, the'rabbit' must be excluded from nine different symbols, but it is already excluded. Since the'rabbit' is also arranged in the same'column 1'as the cell selected in the first matrix to the third matrix, the'rabbit' must be excluded from the selectable symbol set, but it is already excluded. Therefore, the set of selectable symbols becomes eight selectable animal symbols excluding'rabbit', and one of them is randomly selected. 4(a) shows that'goat' is selected in the first row and the second column of the first matrix.

In the same way, 9 blanks may be filled in up to 3 rows and 3 columns of the first matrix 451 by using 9 different animal symbols.

4B shows a process of filling the second matrix 455 after all the blanks of the first matrix 454 are filled.

When symbols are arranged in all cells of the first matrix, a matrix having cells in which symbols are not arranged is additionally selected. In Fig. 4(b), the second matrix 455 is selected.

In the selected second matrix, one cell in which symbols are not arranged is selected. You can select from 1st row and 1st column. First, a set of nine different animal symbols is set as a set of selectable symbols. And there are no symbols placed in the selected second matrix yet.

When checking the symbols arranged in the same'row 1'as the cells selected in the first to third matrices,'rabbits, goats, and donkeys' are arranged in the first row of the first matrix 454. Therefore, they must be excluded from the set of selectable symbols. In addition, when checking the symbols arranged in the same'column 1'as the cells selected in the first matrix to the third matrix,'rabbits, cats, and snakes' are arranged in the first column of the first matrix 454. Excluding the overlapping'rabbit', since 5 symbols are excluded from the set of 9 animal symbols, the set of selectable symbols becomes'turtle, pigeon, snail, and dog', which is a set of 4 animal symbols. Select one of the animal symbols from among them. Referring to FIG. 4(b),'pigeon' is selected at positions in the first row and one column of the second matrix 451.

When arranged as shown in FIG. 4B, a set of selectable symbols that can be arranged in 2 rows and 3 columns of the second matrix 455 will be described.

First, a set of nine different animal symbols is set as a set of selectable symbols. In addition, there are five symbols already arranged in the selected second matrix:'pigeon, snake, puppy, donkey, rabbit', and these are excluded from the selectable symbol set.

When checking the symbols arranged in the same'row 2'as the cells selected in the first matrix to the third matrix,'cats, turtles, and snails' are arranged in the second row of the first matrix 454, and the second matrix ( 455),'donkey, rabbit' is placed. Therefore, they must be excluded from the set of selectable symbols. In addition, when checking the symbols arranged in the same'column 3'as the cells selected in the first matrix to the third matrix,'donkeys, snails, and pigeons' are arranged in column 3 of the first matrix 454, and the second matrix A'dog' is placed in column 3 of (455). Therefore, dogs should also be excluded from the set of selectable symbols. In the end, from the set of 9 animal symbols, 8 pieces of'pigeon, snake, dog, donkey, rabbit, cat, turtle, snail' should be excluded in consideration of overlapping, so the set of selectable symbols is one'goat'.

In the same way, 9 blanks may be filled in up to 3 rows and 3 columns of the second matrix 455 by using 9 different animal symbols.

4(c) shows a process of filling the third matrix 459 after all the blanks of the first matrix 457 and the second matrix 458 are filled.

When symbols are arranged in all cells of the second matrix, a third matrix 459, which is a matrix having cells in which symbols are not arranged, is additionally selected.

In the selected third matrix, one cell in which symbols are not arranged is selected. When the 2nd row and 2nd column are filled as shown in FIG. 4(c), the animal symbol selection process when 2nd row and 3rd column is selected will be described.

Since'turtle, snail, cat, dog, pigeon' has already been arranged in the third matrix 459, except for 5 symbols from the selectable symbols consisting of 9 different symbols, the selectable symbols are 4 animals. The symbol becomes'rabbit, donkey, goat, snake'.

Selectable symbols except for'cat, turtle, snail, donkey, rabbit, goat', which are animal symbols arranged in the same two rows as the cells selected in the first matrix 457 and the second matrix 458, from the selectable symbols Only the'snake' remains.

If'donkey, snail, pigeon, dog, goat, turtle, cat', which are animal symbols arranged in the same three columns as the cell selected in the first matrix, are excluded from the selectable symbols, only'snake' remains as the selectable symbol. In the end, if one randomly selects one of the selectable symbols consisting of only one animal symbol,'snake','snake' is selected.

In the same way, 9 blanks may be filled in up to 3 rows and 3 columns of the third matrix 459 by using 9 different animal symbols.

5 is an exemplary diagram showing an answer matrix generated by a puzzle game operating apparatus applying Sudoku according to an embodiment of the present invention.

FIG. 5(a) is a horizontally arranged answer matrix completed by the above method in the answer matrix generation module, and FIG. 5(b) is a vertically arranged answer matrix.

Since the first to third matrices are all arranged so that only one of the same symbols is contained in each row and each column, the horizontal and vertical arrangement can be freely arranged without changing the elements of each matrix. Therefore, it is easy to output horizontally or vertically according to the shape of the output device.

Hereinafter, generation of the problem matrix will be described using the answer matrix of FIG. 5(b).

6 is an exemplary diagram showing a problem matrix generated by setting blanks in an answer matrix in the puzzle game operating apparatus applying Sudoku according to an embodiment of the present invention.

The problem matrix can be created by setting a blank space at an arbitrary position in the answer matrix. The target number of blanks, which is the total number of blanks set in the problem matrix, can be determined according to the difficulty level. For example, if the difficulty is easy or level 1, the target number of blanks can be set to 1, and if the difficulty is normal or level 5, the target number of blanks can be set to 5, and if the difficulty is difficult or level 9 You can set the target number of blanks to 9.

An embodiment of the present invention is characterized by including a function of capturing a symbol, and since it is desirable for the user to capture a symbol filled in blanks, one symbol selected randomly from among symbols that have not yet been captured in the target symbol set Select first and set it to blank. When the capture target symbol is selected, since there is only one identical symbol in each matrix, one of the three matrices is selected and the position of the capture target symbol in the matrix is set to a blank space.

For example, when generating a problem matrix for the answer matrix of FIG. 5(b),'rabbit' is selected as a capture target symbol, and when a second matrix is selected from among three matrices, the rabbit position of the second matrix The position of the 2nd row and 2nd column is set to blank. Parts set as blank can be displayed and displayed to be separated by shades and borders.

It is checked whether the number of blanks set in the answer matrix matches the target number of blanks, and if the set number of blanks is less than the target number of blanks, a random blank is additionally set in the answer matrix until the number of blanks matches the target number of blanks.

6(a) shows a problem matrix generated by the above method. A total of five positions of'cat and pigeon' in the first matrix 651,'rabbit' in the second matrix 652, and'snail and goat' in the third matrix 653 are set to blanks.

6(b) shows another embodiment of generating a problem matrix. The blanks were set in a total of five positions:'Cat, Pigeon, Rabbit, Snail, Goat', all of which were set only in the second procession (655). By changing the position of the matrix in which the blank is formed, it is possible to induce the user to be interested in the puzzle game.

Hereinafter, input and capture will be described using the problem matrix of FIG. 6(b).

7 is an exemplary diagram illustrating a case in which symbols suitable for blanks are input in the puzzle game operating apparatus to which Sudoku is applied according to an embodiment of the present invention.

When the user selects a position 755 in the second row and three columns of the second matrix of the problem matrix display unit, inputting a chlorine suitable for this position, and selecting the chlorine 735 of the symbol display unit, such selection information is transmitted through the input unit 110 It is transmitted to the suitability preference determination module 253. The user's selection can be input using an input device such as a touch pad, a mouse, or a joystick.

The suitability preference determination module 253 may determine whether or not the appropriate preference is suitable for a corresponding location in the same manner as the method of generating the answer matrix. That is, a set of selectable symbols is obtained for the positions of the 2nd row and 3rd columns of the second matrix selected by the user, and when the symbol'goat' input by the user belongs to the set of selectable symbols, it can be determined as a suitable symbol. If the input symbol'goat' is determined to be a symbol suitable for the selected position, the appropriate symbol'goat' is displayed at the selected position.

In the case of using such a method, the method for obtaining the same set of selectable symbols or the device can be used in the answer matrix generation module and the appropriate symbol determination module, so that the module of the program or circuit can be reused, thus simplifying the control program and reducing parts. Has the effect of.

A method of obtaining a set of selectable symbols that can be arranged in the 2nd row and 3rd column 755 of the second matrix will be described. First, a set of nine different animal symbols is set as a set of selectable symbols. In addition, four symbols of'snake, dog, donkey, turtle', which are symbols already arranged in the selected second matrix, are excluded from the selectable symbol set.

If you check the symbols placed in the same'row 2'as the cell selected in the first matrix to the third matrix,'cats, turtles, and snails' are arranged in row 2 of the first matrix, and in row 2 of the second matrix, 'Donkeys' are placed, and'dogs, pigeons, and snakes' are placed in the second row of the third procession. Therefore, they must be excluded from the set of selectable symbols. In addition, when checking the symbols arranged in the same'column 3'as the cells selected in the first to third matrices,'donkey, snail, pigeon, dog, turtle, cat, snake, rabbit' are arranged. Therefore, they must also be excluded from the set of selectable symbols. Eventually, in the selectable symbol set, except for symbols already arranged in the same matrix, the same row, and the same column, the set of selectable symbols becomes one'goat'.

Therefore, since the symbol'goat' input by the user belongs to the set of selectable symbols, it can be determined as an appropriate symbol.

8 is an exemplary diagram illustrating a case in which symbols that are not suitable for blank spaces are input in the apparatus for operating a puzzle game to which Sudoku is applied according to an embodiment of the present invention.

8(a) shows a case where a user inputs a'snail' at the positions of 1 row 1 column of the second matrix.

First, a set of nine different animal symbols is set as a set of selectable symbols. In addition, five symbols of'snake, dog, donkey, goat, turtle', which are symbols already arranged in the selected second matrix, are excluded from the selectable symbol set.

If you check the symbols placed in the same'row 1'as the cells selected in the first matrix to the third matrix,'rabbits, goats, donkeys' are arranged in the first row (851) of the first matrix, and the second matrix 'Snakes and dogs' are arranged in the first row 852, and'turtles, snails, and cats' are arranged in the first row 853 of the third matrix. Therefore, they must be excluded from the set of selectable symbols. In addition, if you check the symbols arranged in the same'column 1'as the cells selected in the first matrix to the third matrix,'rabbit, cat, snake, donkey, turtle, dog, goat' are arranged. Therefore, they must also be excluded from the set of selectable symbols. In the end, in the selectable symbol set, except for symbols already arranged in the same matrix, the same row, and the same column, the set of selectable symbols becomes one'pigeon'.

Therefore, since the symbol'snail' input by the user does not belong to the set of selectable symbols, it can be determined that it is not a suitable symbol. If the entered symbol is not an appropriate symbol, an'X' is displayed, or the symbol entered in the selected position is not displayed.

8(b) shows a case in which the user inputs'snails' at positions in the 3rd row and 1st column of the second matrix.

First, a set of nine different animal symbols is set as a set of selectable symbols. In addition, five symbols of'snake, dog, donkey, goat, turtle', which are symbols already arranged in the selected second matrix, are excluded from the selectable symbol set.

When checking the symbols placed in the same '3 row' as the cell selected in the first matrix to the third matrix,'snakes, dogs, and pigeons' are arranged in the third row 854 of the first matrix, and the second matrix 'Turtle' is arranged in the third row 855, and'goat, donkey, and rabbit' are arranged in the third row 856 of the third matrix. Therefore, they must be excluded from the set of selectable symbols. In addition, if you check the symbols arranged in the same'column 1'as the cells selected in the first matrix to the third matrix,'rabbit, cat, snake, donkey, turtle, dog, goat' are arranged. Therefore, they must also be excluded from the set of selectable symbols. In the end, in the set of selectable symbols, except for symbols already arranged in the same matrix, in the same row, and in the same column, the set of selectable symbols becomes one'snail'.

Therefore, since the symbol'snail' input by the user belongs to the set of selectable symbols, it can be determined as a suitable symbol. If the entered symbol is an appropriate symbol, the entered symbol is displayed at the selected position.

9 is an exemplary view showing a method of capturing a symbol when all blanks are filled in the puzzle game operating apparatus applying Sudoku according to an embodiment of the present invention.

When all the blanks in the problem matrix are filled, that is, when the number of symbols in the symbol storage matrix is equal to the target number of blanks, the capture symbol determination module 255 selects one symbol from the symbol storage matrix as the captured symbol.

The capture preference determination module 255 may capture other preferences according to the difficulty level. For example, if the difficulty is easy, the symbol stored at the end of the symbol storage matrix is selected as the captured symbol, and if the difficulty is normal, the symbol stored in the middle of the symbol storage matrix is selected as the captured symbol. In this case, it is possible to select an arbitrary symbol as the captured symbol among the symbols stored in the symbol storage matrix.

If the difficulty is easy, the last symbol entered can be selected as the captured symbol. The captured symbol can be indicated by an'O' mark or flashing. The capture symbol display unit 370 may also indicate that the captured animal symbol is a captured symbol by deleting a shadow or highlighting a border.

9(a) shows that the'rabbit' 951 is captured when the last input blank is 2 rows and 2 columns of the second matrix. The capture symbol display part can also indicate the state in which the'rabbit' 971 is captured. In the drawing, the background color is brightly expressed to indicate the captured state. The captured state can be displayed in a variety of ways, such as displaying a border around the captured symbol or moving the captured symbol.

9(b) shows that the'turtle' 953 is captured when the last input blank is 3 rows and 1 column of the second matrix. The captured state was indicated by brightly expressing the background color of the'snail' (973) on the capture symbol display.

Hereinafter, a method of operating a puzzle game applying Sudoku using nine different symbols will be described in detail using a flow chart.

10 is a flowchart illustrating a method of operating a puzzle game using Sudoku according to an embodiment of the present invention.

A difficulty setting step (S110) of receiving and storing the contents of the difficulty level selection from the user is performed. A target preference setting step (S120) of determining the number of target preferences and a target preference set according to the difficulty level is performed.

The target symbol setting step includes receiving a difficulty level, determining the number of target symbols according to the input difficulty level, a target symbol selection step in which one symbol is randomly selected from nine different symbols, and a randomly selected symbol is a target symbol set. If not, adding a target symbol to the target symbol set and storing the randomly selected symbol to the target symbol set, and returning to the target symbol selection step when the number of symbols stored in the target symbol set is less than the target symbol number and repeating.

A problem generation step (S130) of generating a problem according to the difficulty level is performed. The problem generation step can be performed by dividing into an answer matrix generation step and a problem matrix generation step.

The answer matrix generation step is to place nine different symbols in the first matrix, the second matrix, and the third matrix, which are three matrices with three columns and three rows, but nine different symbols in the same row and the same column of the three matrices. Create an answer matrix so that only one symbol is placed.

In the problem matrix generation step, a target number of blanks according to the difficulty level is determined, and symbols of some cells of the answer matrix are deleted according to the target number of blanks to generate a question matrix having blanks.

When the generation of the problem matrix is completed, a matrix output step of outputting the problem matrix with blank spaces on the screen and recording the matrix output time is performed.

A symbol input step S140 of receiving information on the blank selected by the user and a symbol to be inserted into the selected blank is performed.

A step S150 of determining whether the input symbol is a symbol suitable for the selected blank is performed. If the inputted symbol is a symbol that is not suitable for the selected blank, a step S153 of outputting an indication that the inputted symbol is not suitable for the selected blank is performed. When the input symbol is a symbol suitable for the selected blank, the position of the blank and the input symbol are stored in the symbol storage matrix, and a step (S155) of outputting the symbol input to the selected blank is performed.

A step (S160) of checking whether all blanks are filled is performed. If not all of the blanks are filled, it returns to the symbol input step and repeats the step. When all the blanks are filled, the input end time is recorded, and a symbol capture step (S170) of selecting and outputting one symbol from the symbol storage matrix as the captured symbol is performed.

If the captured symbol corresponds to an element of the target symbol set, a capture symbol storage step of adding the captured symbol to the capture symbol set is performed.

A step (S180) of checking whether all the symbols of the target symbol set are captured is performed. If all the symbols of the target symbol set are not captured, it returns to the answer matrix generation step of the problem generation step (S130) and repeats the step. When all the symbols of the target symbol set are captured, a game completion step is performed to output that the game is complete.

In the game completion step, it is checked whether all elements of the target symbol set are present in the capture symbol set, and each matrix problem solving time is calculated at each matrix output time and input end time, and each matrix problem solving time A step of accumulating and storing the total game completion time required to complete the game, and a ranking output step (S190) of displaying a ranking according to the total game completion time.

11 is a flowchart illustrating a method of generating a problem matrix among a method of operating a puzzle game using Sudoku according to an embodiment of the present invention.

The problem generation step (S130) of generating a problem according to the difficulty level may be performed by dividing into a step of generating an answer matrix and a step of generating a problem matrix.

The step of generating the answer matrix may include the following steps.

First, a matrix selection step (S221) of selecting one matrix having cells in which symbols are not arranged from among the first to third matrices is performed. It is preferable to select a matrix in order from the first matrix, but it does not matter if the order of matrix selection is changed.

A cell selection step (S222) of selecting one cell in which symbols are not arranged in the selected matrix is performed. You can select cells by increasing rows or columns in order, starting from 1st row and 1st column.

A step (S223) of checking symbols already arranged in the selected matrix and selecting selectable symbols by excluding them from nine different symbols is performed.

In a matrix other than the selected matrix, a step S224 of excluding symbols arranged in the same row and the same column from the selectable symbols is performed. For example, checking symbols arranged in the same row as the cells selected in the first matrix to the third matrix and excluding them from selectable symbols, and symbols arranged in the same column as the cells selected in the first matrix to the third matrix Check and exclude from selectable symbols can be performed.

A symbol placement step (S225) of randomly selecting and arranging one symbol among selectable symbols in the selected cell is performed.

If there is a cell in which the symbol is not arranged in the selected matrix (S226), it returns to the cell selection step and repeats the step. When symbols are arranged in all cells of the selected matrix, if there is a matrix having cells in which symbols are not arranged (S227), the process returns to the matrix selection step and repeats.

The step of generating the problem matrix may include the following steps.

A step (S231) of checking the difficulty level is performed, and a step (S232) of determining the target number of blank spaces according to the difficulty level is performed.

A step (S233) of randomly selecting one of the symbols that has not yet been captured from the target symbol set is performed.

A blank setting step (S234) of setting the symbol selected in the answer matrix as blank is performed.

A blank check step (S235) of checking whether the set number of blanks matches the target blank number is performed. If the set number of blanks is less than the target number of blanks, a position of an arbitrary blank is additionally determined in the answer matrix (S236), and the step of returning to the blank setting step and repeating is performed.

When the generation of the problem matrix is completed by selecting all the blanks, a step of outputting the problem matrix (S237) is performed.

12 is a flowchart illustrating a method of determining a capture symbol for each difficulty level among a method of operating a puzzle game using Sudoku according to an embodiment of the present invention.

A more detailed look at the operation of the symbol capture step S170 is as follows. In order to capture preferences in more various ways, it is possible to select a preference capture method by utilizing the difficulty level input from the user. To this end, a step (S371) of first checking the difficulty level is performed.

When the difficulty level is checked and the difficulty level is easy (lower) (S372), a step of selecting the symbol stored at the end of the symbol storage matrix as the captured symbol (S375) may be performed.

When the difficulty level is checked and the difficulty level is medium (medium) (S373), a step of selecting a symbol stored in the middle of the symbol storage matrix as a captured symbol (S376) may be performed.

When the difficulty level is checked and the difficulty level is higher than normal (medium), a step (S377) of selecting an arbitrary symbol from among the symbols stored in the symbol storage matrix as the captured symbol may be performed.

When the captured symbol is selected, a step S379 of outputting the captured symbol is performed.
