20 different levels! Really simple rules but pretty hard to solve! The aim of the game is to let a single ball on the board by eliminating the others. A ball is removed when another one jumps over it.
To solve each level you have to let a single ball on the board by eliminating the others. A ball is removed when another one jumps over it. Drag a ball to jump over another one and the ball you just jumped over will be removed.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
