Turns a solo game into a group game

My extended family, including three generations, love this game. It's fun to play alone, just as you would regular paper and pencil Sudoku, or becomes a family board game.


Great family fun

Great fun for those who love old fashioned pen or pencil sudoku
puzzles, but now use colored marbles - no erasing!! Great playing alone as a twosome or more. If you had two boards and two sets of marbles, guess what! Competitive [email protected]

A different way to solve Sudoku. I like it very much.


Love this game!

I enjoy playing ColorKu while I'm watching TV. It's so much more gratifying to handle the balls doing the set-up and then trying to solve than to play Sudoku on my Kindle.
My grandkids jumped right in when I showed it to them. Ages 6 & 10 and they got engrossed in looking to see what color was missing in a row, column, or square.
One complaint - There is a box to put the game cards in but it doesn't fit in the big (game) box!


His joy and excitment brings me to tears.

In talking with a neighbor and his daughter, I found out he loved sudoku, and she word games, she was intimadated by numbers. They spent their time playing thir games.

I ordered it right after christmas. finally gave it to them yesterday. while we taked he opened the package, read all the instructions, and couldn't wait to play.


Great fun to play alone or with a group!

We had so much fun with the game that I bought for a winter family get together weekend! I ended up ordering three more games for the family members to practice before our July family reunion. Even though the suggested age is 8+ my six year old granddaughter was able to catch on to the easier puzzles. Great fun and I have recommended The Grommet to many family members, friends, an co-workers!


Great game

Looks beautiful. Nice color twist from the numbers. My older kids still like it even more because it's nicer to hold and feel than paper

The ColorKu Story

Mad Cave Bird Games - 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.
