wonderful take on Sudoku

I love this! They include puzzles to start you off (and solutions) and also a key so you can take regular Sudoku puzzles and translate them to the Colorku. Well made and looks great on my coffee table. THANK YOU!More > < Less

Great for spatial thinkers . . .

Very pleased with this game. Excellent quality. Good instructions and helpful tips. I have a spatially oriented brain and often do not feel engaged with number or word games. The colors, tactile nature and 3D quality of this game were custom made for me. Would highly recommend for anyone else recovering from a brain inury, dyslexia or the like. Clever, clever way to enjoy Sudoka in an enturely different manner. Kudos to the inventor and The Grommet for recognizing its potential.More > < Less

About ColorKu

Play in Color

Erasing is an inevitable part of Sudoku… or is it?

Dr. Mark Asperheim was tired of repeatedly scribbling and erasing to finish newsprint Sudoku puzzles, and he imagined a more colorful option. Mark started brainstorming with his partner, Cris Van Oosterum, and the two founded Mad Cave Bird Games to bring their vision to life.

ColorKu uses wooden marbles instead of numbers to solve puzzles. Like Sudoku, the object of ColorKu is to fill a 9x9 grid so that every row and column has nine different colored marbles with no repeats, and each 3x3 grid also has nine different colored marbles with no repeats. The marbles make it easy for players to move the colors around, trying different combinations without constantly erasing. The ColorKu set includes 81 balls in nine different colors, 104 puzzle cards, solutions booklet, color conversion card and storage tray.

If you want to add a colorful dimension to family game night, Colorku is ready to play.
