A bouncing ball sits on a tall spiral tower of discs. Drag to turn the tower so a gap comes round under the ball and it drops to the next disc — but if it lands on a red slice, splat. Fall through three discs in one go and the ball becomes a fireball that smashes whatever it hits. Each gold disc ends a level; deeper down there is more red and some discs start to swing.
