ColorKu ColorKu ColorKu ColorKu ColorKu

ColorKu is an exciting twist on the traditional Sudoku game using colorful balls rather than numbers. Start with a few balls in the pockets shown on one of the puzzle cards, and then do your best to fill in the rest of the board so that no color is repeated in any row, any column, or any of the 9 square pockets.
There are many benefits to this challenging brain teaser. Simply stated this is great exercise for the brain! ColorKu puzzles vary from easy to very hard, and you’ll find these puzzles and brain teasers a mental workout, but in a relaxing way.


  • Teaches and requires patience. You’ll be engaged mentally because there's no guesswork in ColorKu. If you guess wrong, you're sunk!
  • Relieves stress. Why? You forget the daily stresses of life. ColorKu requires one to put everything else aside during the time spent on the puzzle.

* There is also a conversion kit that allows the beautiful, heavy wood ColorKu board to be used for Tic-Tac-Ku (sold separately). If you enjoy playing tic-tac-toe with your family or friends then we recommend adding Tic-Tac-Ku

**Both brain strengthening games contain small pieces and hence are not recommended for very young children.
