Canabalt ★★★★☆ ($2.99/ App Store) for the iPhone and iPad is a classic one-button endless running mini game. You play what seems to be a master runner and jumper hopping from buildings to cranes to skyscrapers to billboards in a mad rush with random obstacles coming at you. Despite the fact that there is only one button and requires aw single finger to play, the intensity and excitement is on par with frantic first person shooter games.
