Minor bug fix.

User reviews

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.

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!!!

Deductive reasoning

I love this game! Remember the logic puzzles you played in school? One can think of it has guessing if you don't use deductive reasoning but I always liked those games so if you are into that, this game is right up your alley! Pretty addictive too.

Fantastic logic puzzle!

I love this game! Definitely a challenge. It's all a process of elimination (like sudoku and other logic puzzles). I like that there's an option for hints if wanted/needed, but there's no real "handholding". I always end up playing more than one game whenever I open the app XD
