Abstract:

The Sudoku game board is a white-erase board, or other erasable surface, and it is this application, using an erasable surface, that is new and different. The board has a permanent Sudoku grid on it: first a 3×3 grid which is then sub-divided into 3×3. This grid is the basis for Sudoku puzzles. Using an appropriate marker the player writes in the given numbers of a puzzle, then works the puzzle in another color. The player can easily erase mistakes or other marks and would erase all the numbers on the board after completion. The grid, being permanent, makes this a re-useable surface as the grid would not be removed. The board can be made in various sizes, giving the player more options. The purpose of the game board is to provide a surface for Sudoku puzzles to be worked in a re-useable and more convenient format.
