App Description

So, you think you are smart, eh? Why not put your mind to the test against the sinister Dr. Chaimon as he baffles you with unlimited logic-based puzzles?

Dr. Chaimon loves combination locks, and is using them in diabolical ways to test how smart you are under pressure. The challenger is presented with a random number and multiple combination locks that must be dialed to add, subtract, multiply, or divide together to equal his number.

Sound easy? Not so! You also must face the clock as you are only given a limited time for each puzzle. You’ll need to beat the clock, and Dr Chaimon, as the puzzles become more difficult.
