Save paper and pencil by doing your sudoku on this nifty little peg board. Each playing piece has black and white numbers on either end so you can do the set-up in one color and your solving with the other. This classic logic-based puzzle game is made completely of bamboo and recycled materials. Our set comes with a booklet of sudoku puzzles and you can also use puzzles from other books, the newspaper, etc. The pieces and booklet neatly pack away into the playing board/storage box and we recommend setting it up on a high table away from curious little fingers. The pegs are small and they balance in the circle cut-outs on the board for easy arranging. It's a different, more tactile experience physically moving your numbers around the grids instead of sketching/erasing and we like it!
