Addictive, fun, puzzles are hard but not too hard. Just right. – Birds'n'Blocks Review

Fun puzzles. I like the music and the buzzer some how just makes you want to try again. I guess the buzzer is such a shock the first time you hear it, that you just know it is a joke after that. Concepts of balance, momentum, elasticity all play a part in your sub conscience.
