Sudoku Solvers
The following workbooks each solve a different variation of Sudoku puzzles. They allow the user to enter the known values, then to see the solution one cell at a time or solve the whole puzzle. When attempting to solve a puzzle, the user can check their progress at any time and any errors are highlighted with the reason for the mistake.
Each workbook uses the same algorithms to solve the puzzles, just applied slightly differently for the different puzzle variations. In each case the solvers will find complete solutions for most puzzles rated 'difficult' or 'hard'.
| Sudoku-X |
Solves standard 9*9 sudoku puzzles and also 9*9 Sudoku-X puzzles. |
| Sudoku-Hyper |
Solves 9*9 Sudoku-Hyper puzzles. These have an additional 4 regions overlapping the standard 9 regions. |
| Squiggly Sudoku |
Allows the user to define irregular shapes for the 9 areas on the board, rather than having the 9 standard square regions. |
| Large Sudoku |
Allows the user to select the size of the board from a pre-defined list, ranging in size from 6*6 to 24*24. This also solves Sudoku-X puzzles. |
