We can trace the origins of Sudoku to 19th century France, where versions of the game started appearing in newspapers of the time under the name 'Number Place". The first versions of the game involved the creation of a magic square in a 9 x 9 grid with 3 x 3 subsections, but could use double digit numbers. The modern Sudoku only started to become mainstream in 1986 by the Japanese puzzle company Nikoli, under the name Sudoku, meaning "single number".

The objective is to fill a 9×9 grid with marbles so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called "boxes", "blocks", "regions", or "subsquares") contains all of the different colors included in the game. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a unique solution. Puzzles from your favorite book or newspaper can be recreated on this board by substituting a particular marble color for a particular number.

Eighty one marbles in 9 colors will be included. The particular marble colors are subject to change without notice. In fact the marbles on the far right hand side of the pictures will change pretty regularly. I also include a bag for storage.

The board itself is solid ambrosia maple and is 12" x 12" x 3/4". I have made several of these boards, so the board that you receive may not be the specific board in the picture. It will still be beautiful and it will still be solid ambrosia maple, but the natural variations inherent to working with natural materials such as solid wood make each board unique.

Warning. Choking hazard. Not for use by unsupervised children or anyone who still explores by taste.
