Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to puzzles in general and more particularly to an apparatus and method for providing a puzzle structure in which a surface has a pattern or confining region.

Description of the Related Art

Sudoku is a well-known puzzle-type game. Sudoku typically uses a 9×9 grid of cells divided into nine 3×3 blocks or sub-grids. The object is to fill in the blank cells in a way that each of the numbers 1-9 appear only once in each row, column and block or sub-grid. Some of the cells are already filled in for the player. Typically, there is only one solution to each puzzle. Variations are also known wherein letters or symbols are used rather than numbers. The puzzles have various ratings of difficulty.

Sudoku has become very popular. Many newspapers and magazines include a Sudoku puzzle in the same manner that crossword puzzles have been provided to readers in the past. Like crossword puzzles, compilations of Sudoku games are also provided in books and magazines aimed at the Sudoku player.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention provide for an apparatus and computer program product for providing a sudoku-style game. In an embodiment of the invention, a sudoku-style game for use by a human player includes a game board surface presented to the player which has a plurality of P×Q sub-matrices of cells, each of the cells being divided into a first section and a second section, each section of each cell having sufficient space to contain a visually perceivable indicator, wherein P represents the number of rows in each sub-matrix, and Q represents the number of columns in each sub-matrix, a master matrix having the plurality of P×Q sub-matrices coupled one P×Q sub-matrix to another P×Q sub-matrix to form a desired game board shape, a solution to the game being the completion of the master matrix by the player so that no indicator is repeated more than a respective instructed number of times in each row and column, a plurality of the sections of the cells having respectively assigned indicators presented to the player at the commencement of the game and where the first sections of each of the cells define a first logic game and the second sections of each of the cells define a second logic game.

Referring initially to FIG. 1, a game board master matrix is illustrated that is constructed in accordance with the present invention. The game board master matrix can be formed on a game board surface, printed in a newspaper or other publication, or generated electronically (such as on a computer or cell phone display). The term “game board” will be used herein, however, to denote the displayed game regardless of whether the display is printed on tangible medium or electronically reproduced (e.g., using an electronic display or a portable electronic device), both of which are within the scope of this invention. As shown in FIG. 1, a game board master matrix 100 is formed by a plurality of P×Q sub-matrices 102, where P represents the number of rows in the sub-matrix 102 and N represents the number of columns in the sub-matrix 102, which are coupled one P×Q sub-matrix to another P×Q sub-matrix to form a desired game board shape. In this embodiment, the game board matrix 100 presented to a player has a game board shape illustrated as an M×N matrix of cells 104, where M represents the number of rows in the master matrix 100 and N represents the number of columns in the master matrix 100. The illustrated game board shape of FIG. 1 is a 9×9 matrix; i.e., the master matrix 100 has nine rows and nine columns of cells 104. The game board matrix 100 has four horizontal and four vertical lines. The sub-matrices 102 have two horizontal lines and two vertical lines within the frame of the horizontal and vertical lines of the game board matrix 100, thus creating nine cells in each of the nine sub-matrices 102. The cells are divided into two portions 106 and 108 and create linear paths that define a first logic game and a second logic. Notably, as illustrated in FIG. 4 and discussed in more detail with reference to FIG. 4, the game board shape is not restricted to a square matrix but can have an irregular shape containing the sub-matrices 102.

As illustrated in FIG. 1, each of the sub-matrices 102 are defined by four border lines 101, 103, 105 and 107. In an embodiment, a side border line 107 of a first sub-matrix 102 is coupled to a side border line 105 of a second sub-matrix 102 and a bottom border line 101 of the first sub-matrix 102 is coupled to the top border line 103 of a third sub-matrix 102. In this way, the master matrix game board 100 illustrated in FIG. 1 can be created. Each of the cells 104 are divided into a first section 106 and a second section 108. The division of a cell 104 can be in equal sections or unequal sections. Referring to FIGS. 1 and 2, first section 106 and second section 108 of a cell 104 are both triangles; however, other divisions are available such as squares, rectangles and the like. Continuing to refer to FIGS. 1 and 2, cells 104 can be divided to have a section that is shaded and a section that is non-shaded. For example, as illustrated, first section 106 can be non-shaded, while second section 108 can be shaded. The shading and non-shading defines the direction of play for each logic platform of game play. In other words, the shading and non-shading applied to the first section 106 and second section 108 of the cells 104 provide a path of game play, both in the upward/downward directions as well as the left/right directions. In another embodiment, the shading and non-shading can also indicate a “difficulty rating” for the logic puzzle. For example, shading could indicate a difficulty rating of “HARD” while non-shading could indicate a difficulty rating of “MODERATE”.

The number of sub-matrices 102 and cells 104 are not restricted to the example of FIG. 1. Additional embodiments can have sixteen sub-matrices 102 each with twelve cells 104, or four sub-matrices 102 each with six cells 104. FIG. 2 is an illustration of the game board illustrated in FIG. 1, which shows a solution for that game board. FIG. 3 is an illustration of a second alternative game board in accordance with the invention, where color is used for one of the logic puzzles. As illustrated in FIG. 3, cells 304 can have a section that includes a color and a section that include an indicator or symbol. For example, first section 306 can include an alphanumeric character, e.g., a number, while second section 308 can be a color. The different colors are illustrated in this black and white line drawing as various cross hatching patterns as indicated by color key 301. It is contemplated that any colors could be used for the designators 314 including but not limited to the primary colors and various shades of those primary colors. For instance, a light red or pink along with a dark red could be used.

FIG. 4 is an illustration of a third alternative game board in accordance with the invention, which is a three-dimensional (3D) game board shape. A game board master matrix 400 is formed by a plurality of P×Q sub-matrices 402, where P represents the number of rows in the sub-matrix 402 and N represents the number of columns in the sub-matrix 402, which are coupled one P×Q sub-matrix to another P×Q sub-matrix to form a desired game board shape. In this embodiment, the game board matrix 400 presented to a player has a game board shape illustrated as a 3D matrix of cells 404. As illustrated in FIG. 4, each of the sub-matrices 402 are defined by four border lines 401, 403, 405 and 407. In an embodiment, a side border line 407 of a first sub-matrix 402 is coupled to a side border line 405 of a second sub-matrix 402 and a bottom border line 401 of the first sub-matrix 402 is coupled to the top border line 403 of a third sub-matrix 402. In this way, coupling additional border lines 401, 403, 405 and 407 of additional sub-matrices 402 can create the 3D matrix game board illustrated in FIG. 4.

Each of the cells 404 is divided into a first section 406 and a second section 408. Referring to FIG. 4, first section 406 and second section 408 are triangles; however, other divisions are available such as squares, rectangles and the like. Continuing to refer to FIG. 4, cells 404 can have a section that is shaded and a section that is non-shaded. For example, as illustrated, first section 406 can be non-shaded, while second section 408 can be shaded.

FIG. 5 is an illustration of a fourth alternative game board in accordance with the invention, where icons are used for the logic puzzles. Similar to FIG. 1, as shown in FIG. 5, a game board master matrix 500 is formed by a plurality of P×Q sub-matrices 502, where P represents the number of rows in the sub-matrix 502 and N represents the number of columns in the sub-matrix 502, which are coupled one P×Q sub-matrix to another P×Q sub-matrix to form a desired game board shape. In this embodiment, the game board matrix 500 presented to a player has a game board shape illustrated as an M×N matrix of cells 504, where M represents the number of rows in the master matrix 100 and N represents the number of columns in the master matrix 500. The illustrated game board shape of FIG. 5 is a 9×9 matrix; i.e., the master matrix 500 has nine rows and nine columns of cells 504. As illustrated in FIG. 5, each of the sub-matrices 502 are defined by four border lines 501, 503, 505 and 507. In an embodiment, a side border line 507 of a first sub-matrix 502 is coupled to a side border line 505 of a second sub-matrix 502 and a bottom border line 501 of the first sub-matrix 502 is coupled to the top border line 503 of a third sub-matrix 502. In this way, the master matrix game board 500 illustrated in FIG. 5 can be created. Each of the cells 504 are divided into a first section 106 and a second section 508. The division of a cell 504 can be in equal sections or unequal sections. As illustrated in FIG. 5, various icons or symbols can be used such as $, #, !, ?, %, +, =, &, £ and the like.

In operation, the following rules apply to the sudoku-based games described herein. Each symbol, e.g., number 1-9 should appear only once without duplication in each row and each column of the non-shaded sections, e.g., triangles. Each symbol, e.g., number 1-9 should appear only once without duplication in each row and each column of the non-shaded sections, e.g., triangles. The same symbol, e.g., number, must not appear within the same cell containing a shaded and non-shaded section, e.g., triangle. In an alternative embodiment, a matrix that uses colors for the first and second sections of a cell can be provided. In this embodiment, a puzzle can be developed for early learning, learning difficulty and dyslexia training In this embodiment, unlike the previous logic puzzles, the same indicator is to be placed within both sections of a divided cell.
