Object: Eliminate all marbles.
 
Click on the board to start the game. A marble will appear at the center and four marbles at the border.
 
Then click on a marble at the border. The marble will move to the center and cling to the existing marble. When four marbles of the same colour cling together in a 2x2 square, these marbles will disappear.
 
The default variant uses five colours. The other variants use more or less marble types and are therefore more or less difficult.
