Sudoku game board

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.

1 . Sudoku puzzles are currently being published, but having an erasable Sudoku board creates a new medium on which to work the puzzles, and with different sizes of boards the player is no longer restricted to the small puzzle on paper.
 The particular aspect of the invention that is new and different comprises using an erasable surface with a permanent Sudoku grid on it.   This surface can vary and includes, but is not limited to, erasable white boards and slates, with markers suitable to the surface, and could include a means for erasing.   The board can be made in a variety of sizes.   Traditionally, Sudoku puzzles have squares in the grid, but here other shapes (i.e. rectangles) will also work.   It is this erasable surface with a permanent Sudoku grid that I wish to market or license.
