With this application you can play at the famous game Connect four also called " 4 in line " or " Forza 4 ". You can choose two game mode: Player vs Player or Player vs iPhone. In the second mode there are 5 level of difficulty, but the next releases will introduces more levels.
This application is very friendly user and has a system that can avoid accidental touches (for example if you involuntary touch the screen), so it won't do moves that you don't want making easy the way to win to your opponent.
So... what else could I say? Good luck!!
