The color sudoku puzzle that uses colors instead of numbers. It’s simple! Start by using one of the clue cards to place a number of balls in the specified color on their designated places on the board. Now solve the puzzle by placing the remaining balls so that there is only 1 of each color in every row, column, and 3 x 3 square. Every puzzle has only 1 solution. Puzzles range from simple to challenging to really tough. Use Colorku™ to solve any sudoku puzzle from any source. Comes with a color conversion card that makes it easy. Includes solid-wood game board with 81 wood marbles in 9 eye-catching colors, over 100 puzzles, and a solution booklet.
