This version of the classic logic game gives Sudoku a twist by swapping numbers for colors on a portable board. This sturdy all-wood game includes 81 wood marbles in nine colors. Puzzlers set up the initial board using one of the 104 starter scenarios (with five degrees of difficulty), then solve by filling in the empty spaces on the board so that no color is repeated in any row, column or square. Sudoku puzzles from any book or newspaper can be translated easily to the board and solved as well. Includes solution booklet. 13 1/2" square. (4 3/4 lbs.)
