i-Tiles is a memory matching game for iPhone. To play, touch a tile to flip it over. Then touch another tile to flip the second tile over. If the two tiles match, they will stay face up. If they dont, they will turn face down again. The goal of the game is to flip over and match all of the tiles on the field. To restart a game, touch the timer. Each time you restart, i-Tiles randomly shuffles the tiles on the field. i-Tiles features four levels of difficulty: easy, medium, difficult and hard.
