merge-it for iPhone

From Arend Hintze:

Concentration, focus, and lateral thinking are the three main things you will train with this puzzle game. The objective in this game is to clean the screen of all visible tiles. In order to do so you have to merge them. But merging is restricted to tiles having enough properties in common. This is a new challenging game concept. If you don't like to think or puzzle, this game isn't for you. If you do, you will love this game. Four different game modes, three difficulties and one directly against the clock. The game keeps track of your highscore.
