Super Monkey Ball is the iPhone version of the series and was a launch title of the iTunes App Store.
Like other games in the series the player controls a monkey in a ball. This time the monkey is controlled using the accelerometer of the iPhone. Tilting the device causes the monkey ball to roll, much like a Labyrinth game.
The aim of the game is to collect bananas and reach the end of the track without falling off it into an abyss. There are 110 different stages to complete. All are presented in 3D, but the monkey itself is a 2D sprite.
