Super Monkey Ball is a simple fun game.   You control your choice of a monkey who, for whatever reason, is in a ball.  You tilt the playfield to roll your monkey to the goal, collecting bananas along the way.

The multiplayer games feature ‘Monkey Target’.  You roll your monkey down a ramp then press the ‘A’ button to open the ball, turning it into wings.  You then fly your monkey over the water towards the target, collecting bananas and stars to increase your score.  Finally landing your monkey on the highest score on the target.
