Timberdoodle's Review

Sudoku, the numbers game where players fill each of the blank boxes in a puzzle based on specific rules, has received a makeover. Introducing ColorKu where the use of colors rather than traditional numbers makes ColorKu much more accessible to Sudoku novices, children intimidated by numbers, or just lovers of beauty. ColorKu will improve your child’s memory and logic and will require him to think strategically and solve problems creatively. The gorgeous playing board is solid wood, and comes with eighty-one wooden marbles in nine intense colors. The included dimpled-plastic tray pulls double duty as both a cover when ColorKu is not being used and as a ball holder while playing ColorKu.

Over 100 puzzle cards are included, with difficulty ratings from easy to challenging. Thankfully, the answer to each puzzle is also provided. And because you can readily convert any Sudoku puzzle into a ColorKu puzzle with the addition of the color conversion card, your child will never run out of challenges. ColorKu is such a visually-beautiful game you may find yourself leaving the game out for an impromptu game. We have found that it is perfect as an impromptu diversion for restless visitors whose parents are preoccupied. We fill the board; then, depending on the child's cognitive ability to handle challenges, remove an appropriate number of wooden marbles and let him figure out where the missing pieces belong.

You start by placing the colored marbles on the card onto your board then you have to fill in the rest. Use your logic to play by getting one of each color of marble in each of nine rows, columns and 3 x 3 squares without overlapping with the same color. Each puzzle has only one correct solution.

Please note: due to some very small pieces, this teaching tool could pose a hazard to children under three years of age, or any child prone to putting things in his mouth.

From the Manufacturer:
If you're a fan of Sudoku, you and your family will love this colorful alternative. Instead of using numbers to solve the puzzles, ColorKu uses brightly colored wooden balls.

Colorku is a logic-based number placement puzzle. The object of the game is to fill a 9x9 grid with colored balls so that every row and column have a ball of each color with no repeats and each 3x3 grid has a a ball of each color with no repeats. The puzzles start with a partially completed grid and the players must fill in the rest.

The gameboard-crafted of solid wood-includes 81 balls in 9 different colors, 104 puzzle cards, solutions booklet, color conversion card and storage tray. There are 5 levels of difficulty. Place it on the coffee table and you're ready whenever you feel like a challenge.

Fun and beautiful!

Both my 6 year old and 8 year old love solving these puzzles (and so do mom and dad)! And we can leave it out on the table, because it is so colorful and eye-catching.

Love this!

I don't care for sudoku but for some reason I love this! My older kids and I like to work on the puzzles together and the younger kids love to use the marbles to match colors and make patterns.

This game is very mind challenging for all ages. Our grandchildren found it to be and unusual game they had never saw. Our 16 year old grandson tried his skills with card 3 to start with and mastered it. His next attempt was card 103 (extremely hard). After working on it for over two hours (with lots of rubbing his head, mental sweating and moving the colored balls)he was spot perfect with each placement of each ball when comparing to solution board. Our grandson is high functioning Autism. We found this creation to be fun and challenging for all ages even us old folks, grandparents, enjoyed the challenge.


The challenges are hard but fun. A nice fun spin on sudoku. Well made, worth the money

Not just for kids

We have Colorku as part of our curriculum. My mom was visiting and saw my daughter working on it. She was fascinated by it, so I bought her one for her birthday. She loves it! She enjoys working on it and feels it will help keep her mind sharp.
