ColorKu is SUDOKU in COLOR!
The game sounds simple, but this is a challenge even for the most experienced Sudoku player. Instead of numbers, you get colored marbles and have to use only one of each color in each of nine rows, columns and 3 x 3 squares. Each puzzle has only one correct solution and there is a solution booklet if you get stuck (or need to cheat!) There are 5 levels of difficulty.
ColorKu is made of solid wood and comes with:
81 wooden balls in 9 different colors
104 puzzle cards
