Terrific fun, challenging, logic skill builder

I love this game! You have to develop a methodical pattern of testing. Each level helps you learn the logic skill to use in the next level. Hint: start with all one color, and test color by color.

If you're methodical and consistent, you can win every game. As more colors and patterns are introduced you have to adjust your method. You can often figure out where a color or pattern has to be. With enough skill I think you can win every game. The number of guesses increases with each level.

Thanks for hours of fun, game makers!!!

Great logic game.

Well-made, simple yet challenging logic game. It won’t eat your battery if you are looking for something to play on a long flight. It might take a few games before you understand the clues, but worth it once you do, especially if you like pattern matching logic games. Do the lower levels only to learn the clue patterns. The real game is the hardest level.

New Favorite

If you want a change from Sudoku, this is the game! Not easy but if you like logic puzzles this will challenge you. Best advice I got from my friend who recommended this is, "Make a guess and proceed from there. Even if you get no clues, it's still a clue that eliminates that color and shape." Now, I'm on at the Grand Master level!!! Awesome game!
