Object: Eliminate all marbles.
 
Click on the board to start the game. A marble will appear at the center and one at the border. The marble at the border will have a different colour at each move.
 
Click a square orthogonally adjacent to the center marble to place the border marble. All new marbles must be placed orthogonally adjacent to existing ones.
 
Monochrome groups of three or four marbles will disappear if they are in a certain arrangement. The necessary arangement depends on the colour of the marbles. The arangements are shown on the border.
 
The default variant uses three colours. The other variants use more marble types and are therefore more difficult.
