ColorKu is SUDOKU in COLOR! Start with one of the 104 puzzle cards, then get one of each color in every row, in every column, and in every 3 x 3 box.

The game sounds simple, and yet it can be oh so tough! Each puzzle card starts with “clues” telling which marbles in which color to place where on the board. Then you fill in the rest of the board.

Five levels of difficulty, while even very young children enjoy sorting by color and creating or copying patterns. Also available is the for playing a colorful game of Tic Tac Toe.
