This game is all about math.
It requires really deep thinking and concentration.
Therefore, if you are not into it, you probably wont like this game.
100%MathGeek is minimalistic, well-defined and absolutely fair.
It is a great game for training your brain, and probably one of the most difficult puzzle games in the iTunes store.
The main idea: The player is requested to place the right mathematical operations symbols to get a "solution".
