The size and positioning of the three (3) grids is adjustable to fit the given embodiment, and any variation is size or position of the grids is to be considered apparent and obvious to the disclosure.
The game puzzle grid (X) 102 incorporates the elements of the game as well as references for each row and column as an aid for playing the game. The game puzzle grid (X) 102 generally comprises a nine (9) by nine (9) grid of puzzle cell 120. The grid comprises nine (9) puzzle column 1110, each puzzle column 110 identified via respective puzzle column identifiers 112. The game puzzle grid (X) 102, more specifically a puzzle layout 126, comprises nine (9) puzzle rows 114, each puzzle row 114 identified via a respective puzzle row identifiers 116. The game puzzle grid (X) 102 is segmented into nine (9) box 122, identified via a box horizontal defining line 142 and a box vertical defining line 144. The box 122 is a three (3) by three (3) grid of puzzle cell 120. The puzzle cells 120 are proportional in size to the grid, and therefore, the size of each cell 120 is determined by the size of the grid in which it is contained. A region 124 comprises three (3) adjacent box's 122 and can be oriented horizontally (as shown) or vertically (understood). A puzzle consists of nine (9) box's 122 arranged in a three (3) by three (3) grid for a total of eighty-one (81) puzzle cell 120.
The strategy row grid (Y) 104 is provided in a nine (9) by nine (9) array of row game piece 134, each row game piece 134 being placed into a marked cell. The strategy row grid (Y) 104 aids the user by informing the user of the status of each respective row of the game puzzle grid (X) 102. One of the objectives of the Sudoku puzzle is to place one and only one each of the numbers 1 through 9 across the row. Once a number is placed into the row of the game puzzle grid (X) 102, the same number is no longer used in the respective row. The strategy row grid (Y) 104 comprises nine (9) row grid row 132, each row grid row 132 including a series row game piece 134, wherein the series being one each of the numbers 1 through 9 as illustrated. Each column is identified via row grid identifiers 130. Additionally, the strategy row grid (Y) 104 includes a pair of region horizontal defining lines 142 as a visual aid for aiding in the association of each of the three (3) respective horizontal regions 124 of the game puzzle grid (X) 102.
The strategy column grid (Z) 106 is provided in a nine (9) by nine (9) array of column game piece 140, each column game piece 140 being placed into a marked cell. The strategy column grid (Z) 106 aids the user by informing the user of the status of each respective column of the game puzzle grid (X) 102. Another of the objectives of the Sudoku puzzle is to place one and only one each of the numbers 1 through 9 along the column. Once a number is placed into the column of the game puzzle grid (X) 102, the same number is no longer used in the respective column. The strategy column grid (Z) 106 comprises nine (9) column grid columns 138, each column grid column 138 including a series column game piece 140, wherein the series being one each of the numbers 1 through 9 as illustrated. Each row is identified via column grid identifiers 136. Additionally, the strategy column grid (Z) 106 includes a pair of region vertical defining lines 144 as a visual aid for aiding in the association of each of the three (3) respective vertical regions 124 of the puzzle grid (X) 102.
The Sudoku strategy aid layout 100 can additionally include a notes section 108 providing the user with an area for making notations. A note pad 146 can be placed in the notes section 108, providing the user with a means for making notes and discarding the notes as needed.
The Sudoku strategy aid layout 100 is presented on a game board. The game board can be made out of, and printed on, a variety of materials, including but not limited to, a cardboard based material, paper products, fabric, plastic, wood, and a multitude of other materials not referred to herein which are to be considered apparent and obvious to the disclosure.
The initial start configuration is presented as two different embodiments, as illustrated in FIGS. 2 and 3. A paper version is presented in FIG. 2 and a game piece version is presented in FIG. 3. The concept behind each is the same, with a slight variation upon the execution of each. An original game is provided via a book, Internet, and the like, and is copied onto the game puzzle grid (X) 102. In the paper version, the original game configuration is generated by writing the numbers in the respective cells 120 in a color, which differs from the solution color. As each number is written into the respective puzzle cell 120 of the puzzle grid (X) 102, that number is identified in the respective row grid row 132 and marked out. An example is presented via starter number 150 (number “9”) being written into cell A9 of the puzzle grid (X) 102. The number “9” is the identified in the respective row grid row 132 and marked out 152. The same number “9” is identified in the respective column grid column 138 and marked out 154. This is repeated until all of the starter numbers are entered into the puzzle grid (X) 102.
In the game piece version, the original game configuration is generated by identifying and placing the respective row game piece 134 into the respective cell 120. This is illustrated as a starter game piece move 160. In accordance with the starter game piece move 160, the player identifies the starter number in the row grid row 132 of the row grid (Y) 104, removes the row game piece 160a from the row grid row 132, flips the game piece 160a to the opposite side, and places the game piece 160 into the respective starter cell of the puzzle grid (X) 102 a starter puzzle game piece 160b. 
In parallel with each started game piece move 160, the user identifies the same number in the same column. The identified column grid game piece is flipped over, and placed back into the same cell as illustrated via a played column game piece 160c. This process is repeated until all starter pieces are transferred from the row grid (Y) 104 to the puzzle grid (X) 102 and each respective number is identified in the row grid (Y) 104 and the column grid (Z) 106. Upon completion of arranging the starter configuration, the player is ready to begin solving the Sudoku puzzle.
The player can utilize the Sudoku strategy aid layout 100 as an aid in solving the puzzle. The user scans in three different groupings to correctly identify which number is placed into a respective cell. The method of solving the puzzle utilizing the Sudoku strategy aid layout 100 is demonstrated in FIGS. 4 through 15 herein.
The player scans the row grid (Y) 104 and the column grid (Z) to determine the lowest number of remaining numbers. Referring to FIG. 4, the lowest quantity of remaining numbers (2) is found in row E of row grid (Y) 104. The two numbers are 1 and 7. Puzzle row 114 (E) has two vacant cells 120, found in columns 4 and 6. The column grid (Z) 106 presents that both numbers have not been played in either column 4 or 6 and therefore doesn't provide a solution. The next lowest quantity of remaining numbers (3) is found in column 138 (1) of the column grid (Z) 106. The three remaining numbers are 3, 7, and 9. The puzzle column 110 (1) has vacant cells in puzzle rows 114 (B, C, and F). By scanning the row grid (Y) 104, the player identifies that the number “3” is already used in rows 132 (B and R therefore, the number “3” can only be placed into cell 1C. The player transfers the row game piece 162a in accordance with move 162 to cell 1C as illustrated via puzzle game piece 162b. The move is also recorded by flipping the associated column game piece 162c in the respective column 138 (1). Ali subsequent moves are identified as follows: the move is identified as move “###”; the row game piece is identified as “###a”; the puzzle game piece is identified as “###b”; and the column game piece is identified as “###c”; wherein “###” is a variable representative of the respective move element number. This scheme is provided for clarity and to minimize repetitive information.
Referring to the moves presented in FIG. 5, continuing with the same column 138 (1), the remaining numbers are “7” and “9”. The puzzle column 110 (1) has vacant cells in puzzle rows 114 (B and F). By scanning the row grid (Y) 104, the player identifies that the number “7” is already used in row 132 (F) therefore, the number “7” can only be placed into cell 113 and the player completes the move in accordance with move 166. Column 138 (1) has only one number “9” remaining. The number “9” is then placed in the one remaining vacant cell (cell 1F) of puzzle column 110 (1) and the player completes the move in accordance with move 164.
Referring to the moves presented in FIG. 6, row 132 (E) has not improved in aiding in the solution. Therefore, the player can consider using row 132 (B), row 9 of the column grid (Z) 106, column 138 (8), and column 138 (9). Column 138 (9) of column grid (Z) 106 presents “4”, “5”, and “7” are available for placement. The puzzle column 110 (9) has vacant cells in puzzle rows 114 (D, G, and H). By scanning row 132 (H) of row grid (Y) 104, the player identifies that the numbers “4” and “7” are already used. Therefore, the number “5” can only be placed into cell 9H and the player completes the move in accordance with move 168. Column 138 (8) of column grid (Z) 106 presents “3”, “4”, “5”, and “8” are available for placement. The puzzle column 110 (8) has vacant cells in puzzle rows 114 (A, C, F, and 1). By scanning column (3) of row grid (Y) 104, the player identifies that the number “3” is available in four rows 132 (D, G, H, and I), but three of the four of the respective puzzle rows 114 (D, G, and H) already have numbers inserted. Therefore, the number “3” can only be placed into the remaining cell, cell 81 and the player completes the move in accordance with move 170. The same is repeated for the number “4”, noting the number “4” is available in four rows 132 (A, B, D, and G), but three of the four of the respective puzzle rows 114 (B, D, and G) already have numbers inserted. Therefore, the number “4” can only be placed into the remaining cell, cell 8A and the player completes the move in accordance with move 172. Scanning the remaining numbers in the aide and strategy boards, the number “9” has only three remaining placements, in puzzle columns 110 (3, 4, and 5) and puzzle rows 114 (B, C, and Puzzle column 110 (3) has numbers already inserted into puzzle rows 114 (C and I). Therefore, the number “)” can only be inserted into cell 3B and the player completes the move in accordance with move 174.
Referring to the moves presented in FIG. 7, row 132 (B) has now improved in aiding in the solution. Row 132 (B) of row grid (Y) 104 presents “4” and “8” are available for placement. The puzzle row 114 (B) has vacant cells in puzzle columns 110 (4 and 6). By scanning column 138 (4) of column grid (Z) 106, the player identifies that the number “4” is already used. Therefore, the number “8” can only be placed into cell 4B and the player completes the move in accordance with move 176. Additionally, the number “4” can only be placed into cell 6B and the player completes the move in accordance with move 178. Column 138 (8) of column grid (Z) 106 presents “5” and “8” are available for placement. The puzzle column 110 (8) has vacant cells in puzzle rows 114 (C and F). By scanning rows 132 (C and F) of row grid (Y) 104, the player identifies that the number “4” is already used in row 132 (C). Therefore, the number “8” can only be placed into cell 8C and the player completes the move in accordance with move 180, Additionally, the number “5” can only be placed into cell 8F and the player completes the move in accordance with move 182.
Referring to the moves presented in FIG. 8, column 138 (9) of column grid (Z) 106 presents “4” and “7” are the only remaining numbers for placement within that column 138 (9). The puzzle column 110 (9) has vacant cells in puzzle rows 114 (D and G). In reviewing the row grid (Y) 104, the numbers “4” and “7” are both available for each of the two open puzzle rows 114 (D and G), therefore this method does not provide a solution, Looking further, the box 122 (1D) already has a number “7”, leaving the number “4” as available for the box 122 (1D). Therefore the number “4” is placed into cell 3D and the player completes the move in accordance with move 184. Column 138 (9) of column grid (Z) 106 presents “5” and “8” are available for placement. The puzzle column 110 (9) has vacant cells in puzzle rows 114 (D and G). By scanning rows 132 (D and G) of row grid (Y) 104, the player identifies that the number “4” is already used in row 132 (D) (previously played in move 184). Therefore, the number “7” can only be placed into cell 9D and the player completes the move in accordance with move 186. Additionally, the number “4” can only be placed into cell 9G and the player completes the move in accordance with move 188.
Further scanning within FIG. 8, the player can recognize column 9 of row grid 104 having only two “9's”. The puzzle columns 110 (4 and 5) have vacant cells in puzzle rows 114 (C and Therefore, the placement of the “9's” is indeterminate at this time using this method. The player continues, recognizing column 138(3) of column grid (Z) 106 presents “1”, “3”, and “8” are still available for placement. Considering the three first (least quantity of placements available compared to the quantity of the numbers “1” and “8” still remaining), Column 3 of the row grid (Y) 104 presents that the number “3” can be placed into puzzle rows 114 (D, G, and H). Puzzle cell 3H already received the number “6”, therefore, it is no longer considered open for placement. A number “3” is already placed within box 122 (1D). Therefore, the only remaining available cell for the number “3” is 3G and the player completes the move in accordance with move 190.
Referring to the moves presented in FIG. 9, the player recognizes the number “3” and the number “9” equal in the lowest remaining quantities available for placement with two (2) per number, Rows 132 (D & H) note that puzzle columns 110 (4 & 6) still need placement of the number “3”. Columns 138 (4 & 6) note that puzzle columns 110 (4 & 6) still need placement of the number “3”. Considering the four potentially available puzzle cells (4D, 6D, 4H, & 6H), the player recognizes cell 6D as already having the number “9”, therefore the number “3” must be placed into cell 41) and the player completes the move in accordance with move 192, The only remaining number “3” is then placed into cell 6H and the player completes the move in accordance with move 194.
Referring to the moves presented in FIG. 10, the player notes the various rows 132, columns 138 and quantities of numbers are high and the simple solution methods are limited. Using column 138(2) of column grid (Z) 106, four numbers are available for play “1”, “5”, “6” and “8”. The player can then turn to the use of a box 122 to determine number placements. Investigating box 122 (1G) the numbers “6” and “8” have already been played, leaving the numbers “1” and “5” for placement. By viewing the row 132 of row grid (Y) 104, the player notes the number “1” is no longer available for play in row 132 (G), therefore the number “5” must be placed into cell 2G and the player completes the move in accordance with move 196. With that, the number “1” is then placed into cell 21 and the player completes the move in accordance with move 196, A similar process is completed within box 122 (7D). Box 122 (7D) has two open cells 120 (7D and 7F), and only two remaining numbers “1” and “8”. By reviewing rows 132 (D & F) of row grid (Y) 104, the player identities from row 132 (D) that the number “1” has previously been played. Therefore, the number “1” must be placed into cell 7F and the player completes the move in accordance with move 200. Therefore, the remaining number “8” to complete the box 122 (7D) is placed into cell 7D and the player completes the move in accordance with move 202.
The puzzle solution continues in FIG. 11, Column 138 (2) of column grid 106 presents two remaining numbers “6” and “8”. The number “6” is already used in puzzle row 114 (A), therefore the number “6” is placed into cell 2D and the player completes the move in accordance with move 204 and the number “8” is placed into cell 2A and the player completes the move in accordance with move 206. Continuing forward, column 138 (3) of column grid 106 presents two remaining numbers “1” and “8”. The number “1” is already used in puzzle row 114 (F), therefore the number “8” is placed into cell 3F and the player completes the move in accordance with move 208 and the number “1” is placed into cell 3A and the player completes the move in accordance with move 210. Looking at the strategy grids, row 132 (H) of the row grid (Y) 104 only has two numbers “1” and “2”. Puzzle row 114 (H) has two vacant cells in columns 110 (4 and 7). Column 7 already has the number “2”, therefore, the number “2” is placed into cell 7H and the player completes the move in accordance with move 212 and the number “1” is placed into cell 4H and the player completes the move in accordance with move 214.
With the number placements into puzzle column 110 (7), the player can recognize that each of the two box's 122 (7A and 7G) have only one (1) remaining placement each. Box 122 (7A) indicates the number “7” is needed in cell 7C, therefore, the number “7” is placed into cell 7C and the player completes the move in accordance with move 216. Box 122 (7G) indicates the number “6” is needed in cell 71, therefore, the number “6” is placed into cell 71 and the player completes the move in accordance with move 218. The player continues to scan for clearly identified moves and recognizes row 132 (D) has only one remaining number, the number “5”.
