The game takes place over 12 levels. On each level, the player has to guide a group of bouncing balls from the right edge of the level to the left edge. The balls are constantly bouncing, and the player can only alter their travel speed (by moving the joystick left or right) or make them bounce higher (by pressing the fire button). The objective of the game is to collect ten balloons; doing so will advance the player to the next level.

Various different dangers appear on the levels, including sharp rocks, venus flytraps, hedgehogs and flying birds. The game starts with four balls, and each time the balls collide with a dangerous object, one ball bursts. If all four balls are burst, the player loses a life.
