In this game there are balls of different colours, and you have to move the balls so that 5 or more balls of the same colour connect in a straight line so that the balls are destroyed. The lines can be horizontal, vertical or diagonal. After each move, new balls will be formed and you lose the game when the whole board is filled with balls.
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.
