The present invention relates to games that involve logic-based puzzles and, more specifically, to a board game and method of play that includes conversion of a solitaire numeric puzzle game to a multiplayer game of completing number patterns initiated by a given set of numbers.
2. Description of the Related Art
A variety of games and puzzles have been introduced that involve numbers and their logical arrangement in specific patterns based on a set of rules. Typically these puzzles have a solution pattern that a player develops based on the relationship of the numbers in certain locations on a grid. Many of these puzzles are solitaire games, allowing only one player to enjoy completing the logic-based pattern of numbers. In some cases, number puzzles are evolved variations of ancient games based on certain mathematical rules. A particular game, Su Doku (also referred to as Sudoku, Soduku, Suduku, and Su Duku) is a solitaire puzzle involving ordered rows and columns of numbers. Both puzzle aficionados and others generally interested in logic have exhibited increasing interest in playing Su Doku.
Rules of play for numeric games such as Su Doku are generally rooted in the rules for Latin Squares, a game dated as far back as the thirteenth century. Latin Squares puzzles are solitaire puzzles that include a grid of cells formed by columns and rows and a set of numbers or symbols, each appearing once in each row and column of the solution pattern. Su Doku is an evolved version of Latin Squares having nine columns and nine rows forming a grid of eighty-one cells. Each cell in the solution pattern is assigned a number from 1 to 9 and each number appears only once in any given row or column. The cells are further divided into groups of nine cells, each group forming sub-grids having three columns and three rows. In the solution pattern, each cell in the respective sub-grids is assigned a distinct number from one to nine, each number appearing only once in any given sub-grid. Typically, the puzzles provide the solution numbers for some of the cells and the player has to develop the rest based on the numbers provided. The number of cells in the puzzle with the solution numbers provided determines the difficulty of a given Su Doku Puzzle.
A common strategy for developing the numbers is to write all the numbers, one to nine, in each cell of the Su Doku puzzle and determine the solution numbers in each cell by a process of elimination. Using this strategy, a player denotes unselected numbers in each cell by crossing them out. Although this strategy is an effective method of determining the solution numbers, it can result in a cluttered playing area. For example, a number may have to be rewritten in a cell next to where it was crossed out because it was crossed out in error. A number may be crossed out in error when that number was selected as a solution number in error in the corresponding row, column or sub-grid. Additionally when the puzzle is partially developed and there is numerous crossed-out numbers on the playing area, it becomes difficult to distinguish which cells remain to be filled with a number and which numbers remain available as solution numbers.
Furthermore, similar to their predecessors, recent games such as Su Doku are generally solitaire games, allowing only one person to play the game. Typically these puzzles remain on paper and the player must use a writing instrument to solve the puzzles. Certain variations of Su Doku accommodate more than one player and provide other means of playing the game such as a single board and numbered game pieces or felt pens and an erasable playing area. However, such variations are typically limited to either two or four players and do not provide for a more cohesive way of executing the process of elimination strategy described above. Therefore, these variations simply provide an enlarged version of the original game.
Although number puzzles such as Su Doku can be entertaining and intellectually challenging, they remain substantially unchanged from their primitive origins and are limited in the number of players that can simultaneously play against each other in one game. Furthermore, existing tools for playing such games impose obstacles that inhibit execution of strategies to solve the puzzles expediently. Therefore, there is a need for a number puzzle and/or game that allows an unlimited number of players to play against one another and that is configured to accommodate effective execution of strategies.
One embodiment of the present invention provides an apparatus for playing a board game including a playing plane having a master grid with a plurality of cells formed by columns and rows, wherein the master grid is subdivided into sub-grids, each sub-grid having a number of cells equal to the number of columns in the master grid, each cell divided into a number of sub-cells equal to the number of columns in the master grid, and each sub-cell assigned a distinct indicia, the total number of distinct indicia equal to the number of columns in the master grid; a solution plane having a plurality of cells corresponding to respective cells of the playing plane and configured to provide an indication of correctness of a user-proposed solution; and at least a first game piece carrying at least two distinct indicia and adapted to randomly display at least one distinct indicia in response to a manipulation of the first game piece for providing an indication of a first rule of play applicable to a first game parameter of a current player.
In accordance with another embodiment, a method of game play for one or more players, using a game apparatus having at least a first game piece carrying at least two distinct indicia and configured to randomly display at least one distinct indicia in response to a manipulation of the first game piece, predetermined solution indicia corresponding to a cell on a playing plane having a master grid with a plurality of cells formed by an equal number of columns and rows, wherein the master grid is subdivided into sub-grids, each sub-grid having a number of cells equal to the number of columns in the master grid, each cell divided into a number of sub-cells equal to the number of columns in the master grid, and each sub-cell assigned a distinct indicia, the total number of distinct indicia equal to the number of columns in the master grid wherein one solution sub-cell per cell is assigned an indicia that is the predetermined solution indicia for the corresponding cell of the playing plane and each solution indicia occurs once in each sub-grid, row and column of the master grid. The method includes a player manipulating the first game piece to randomly display at least one of the distinct indicia carried by the first game piece; the current player selecting at least one sub-cell on the playing plane; the current player revealing a signal on a solution plane having a plurality of sub-cells, respectively corresponding to the selected sub-cell of the playing plane; and tallying points received during play for each player as selection of the solution sub-cells associated with the solution indicia assigned to the corresponding cell wherein the player with the highest points is the winner and at least one of the selecting the at least one sub-cell and tallying the points is subject to a first rule of play indicated by the randomly displayed indicia of the first game piece.

In one embodiment of the present invention as illustrated in
The third game member 16 includes a first surface 29 having indicia forming a master grid 30. The master grid 30 includes an equal number N of rows and columns forming a plurality of cells 32. The first surface 29 of the third game member 16 can be positioned against a second surface 31 of the second game member 14, for example when the second game member 14 rests on the third game member 16.
The game apparatus 10 may include an optional substrate member 34, supporting a second surface 36 of the third game member 16 on a first surface 38 of the substrate member 34, for example when the third game member 16 rests on the substrate member 34. Additionally, or alternatively, the game apparatus 10 may include at least one optional fastening member 40, for example a threaded screw 42 and a wing nut 44 as shown in
The game members 12, 14, 16 can also be secured using other methods such as, but not limited to, adhesives between the mating surfaces, at least one clamp, joint welds in embodiments in which the members 12, 14, 16 are weldable, hook and loop fasteners mounted on the mating surfaces, or any other fastening or securing mechanism, device, or method capable of securing the game members 12, 14, 16 in a manner that preferably allows disassembly.
Additionally, or alternatively, the game apparatus 10 may include an optional cover member 35 having a plurality of openings 37 alignable with the plurality of openings 28 in the plate 24, and at least one corner aperture 46 through which the threaded screw 42 may extend to fasten to the wing nut 44.

In the exemplary embodiment of
The indicia 60 in the sub-cells 58 allow a player to visually compare the displayed solution indicia 56 provided as clues and eliminate these indicia or numbers from the list of available solution indicia 60 included in the sub-cells 58. Therefore, the player can develop the solution indicia 56 for each cell 22 by a process of elimination.
For example in
Furthermore, a sub-grid 68 to which the cell 66 belongs displays the numbers 1, 4, 5, 6, and 7 as the given solution indicia 56 in the respective cells 22. Therefore, the player can also eliminate an additional number, 4, from the potential solution numbers 60 in the cell 66 because the rules of play include that each distinct solution indicia 56 may appear only once in a sub-grid 52, 68. Therefore, the player can narrow his choice for the solution indicia 56 assigned to the cell 66, from nine possible numbers 60 to four possible numbers 60, namely, the numbers 2, 3, 8, and 9.

Furthermore, the cover member 35 and the second game member 14 can be fabricated from transparent or translucent material such as glass, plastic, crystal, acrylic, silicone, or any other transparent or translucent material. Therefore, the cover member 35 does not conceal the first game member 12. Similarly, the second game member 14 does not conceal the third game member 16. Upon assembly of the game apparatus 10, the plurality of openings in the cover member 35 are substantially aligned with the sub-cells 58 of the first game member 12, the plurality of openings 28 in the plate 24 of the second game member 14, and the sub-cells 78 of the third game member 16.
The tool 74 can be configured to project through the cover member 35 and puncture the first game member 12, and to extend at least partially through the second game member 14. Therefore, the current player selects a sub-cell 58 of the first game member 12 by inserting the tool 74 through an opening 37 aligned with an indicia 60 in a sub-cell 58 of the first game member 12, the player selecting the indicia 60 to be the solution indicia 56 for the corresponding cell 22. Upon inserting the tool 74 through the opening 37 of the cover member 35, the tool 74 punctures the corresponding sub-cell 58 of the first game member 12 and proceeds through the corresponding opening 28 of the second game member 14. Upon removing the tool 74, the underlying indicia 80, 82 of the corresponding sub-cell 78 of the third game member 16 can be viewed through the punctured opening.
Revealing of the first indicia 80 of the third game member 16 indicates that the current player has made a correct selection and that player receives points and repeats the above process to speculate the solution indicia 56 of the solution pattern 54 illustrated in
Therefore, the game apparatus 10 eliminates clutter on the playing area that is common when playing existing number puzzles and/or games. The apparatus 10 further provides clear visual indications, showing which cells 22 remain to be solved and which sub-cell indicia 60 remain as choices for the solution indicia 56 for the respective cells 22. Additionally, the apparatus 10 does not limit the number of players while still accommodating a player to play a solitaire game.
Upon developing the solution pattern 54 of the puzzle of the first game member 12, a new puzzle or game may be played by removing the first and the third game members 12, 16 and replacing them with new game members 12, 16 that include a new puzzle and a new pattern of correctness indicia, respectively.
It will be understood that other embodiments of the present invention may or may not include all of the above components, or may include additional components. For example, in an embodiment as shown in
In such an embodiment, players may use the tool 74 and rules of play as described above to develop the solution pattern 54 (

In yet another embodiment illustrated in
In embodiments in which the tool 248 includes fiber optic material, when ambient light is sufficient to travel through the tool 248, the LED lights can be eliminated or deactivated. The ambient light travels through the fiber optic material, reflecting an image of an underlying indicia corresponding to the first signal 232 or the second signal 234 toward the external surface 250 to communicate the corresponding first signal 232 or second signal 234. The indicia may include colors, alphanumeric characters, symbols, or any combination thereof.
In another embodiment, the tool 248 can include a magnifying device such as a magnifying glass at the external surface 250 of the tool 248 that visually communicates a signal substantially the same as the signal on the underlying solution layer 204, which is produced as described above.
In yet another embodiment as illustrated in
Additionally, or alternatively, known auto-sensory mechanism may be incorporated in electronic embodiments of the present invention so that a player can play the puzzle against a computer or with the aid of a computer giving the player hints by narrowing the possible solution numbers 218 to less than nine numbers per each cell 212.
A further aspect of any of the embodiments described herein includes at least a first game piece 300 having distinct indicia 302 as illustrated in
Additionally, or alternatively, in yet a further aspect, any of the above embodiments may comprise at least a second game piece 301 having indicia 303 as illustrated in
In embodiments that include both the first and second game pieces 300, 301, the indicia 302, 303 on the game pieces 300, 301 may be substantially identical or different. Furthermore, instead of being cubic, the game pieces 300, 301 may comprise any other shape, for example octagonal. Alternatively, the game piece 300, 301 can be electronically activated. For example, the game pieces 300, 301 may comprise an activating trigger 305 to initiate a random or predetermined number-generating routine and display a resulting number on a surface 307 of the game piece 300, 301. In other electronic embodiments, the number may be generated by otherwise manipulating the game pieces 300, 301, such as shaking the game pieces 300, 301, to emulate a feel of rolling dice.
Additionally, or alternatively, in still further aspects, any of the above embodiments may comprise at least a third game piece 308 having at least a first indicia 310 as illustrated in
In the illustrated embodiment of
In one embodiment, at least one game piece, such as the third game piece 308 illustrated in

Subsequently, the current player can optionally mark the selections on the first game member 12, using a writing tool, such as the writing tool 106 illustrated in
Additionally, in any of the embodiments described herein other configurations are possible to generate the first and second signals respectively indicating whether a correct or an incorrect selection has been made. For example when determining the correctness of the selections, in an additional aspect of the illustrated embodiment of
One of skill in the art will appreciate these and other variations that can be made to embodiments of the game apparatus 10, 90, 200 without deviating from the scope of the present invention. For example, extra points can be awarded to a player who correctly selects a majority of cells 22, 212 per each sub-grid 52, 210 and/or per the master grid 20, 206. Additionally, or alternatively, extra points may be awarded to a player who correctly selects a maximum number of cells 22, 212 consecutively situated in a column or a row of the master grid 20, 206. Other rules and provisions for extra points are possible. For example, extra points may be awarded to a player who makes a correct selection for a last unresolved cell 22, 212 in one of the sub-grids 52, 210.
Additionally, different cells 22, 212 or sub-grids 52, 210 may be assigned different points or a distinct multiple factor. When the players make a correct cell selection or complete a sub-grid 52, 210, they are awarded points or their points are multiplied based on the points or multiple factors assigned to the different cells 22, 212 or sub-grids 52, 210.
As illustrated in
In this disclosure, examples of game parameters that can be affected by the randomly displayed indicia on the game pieces 300, 301, 308 have been described. However, one of ordinary skill in the art will appreciate that these or other game pieces may be utilized to affect other game parameters or include indicia other than numbers. For example, other game pieces may carry letters or words conveying additional restrictions or rules, such as the current player losing a turn or gaining a turn, the score of the current player multiplying by a factor if the current player's next speculation identifies the correct sub-cell for the corresponding cell, or any other rule affecting any other parameter. In this manner the winner of the game, will not be certain until the game ends and the game is more challenging.
