To start the game, click the left board. Sixty coloured balls will drop.
Click three balls such that they form one of the two configurations given on the right side of the board. The balls don't have to be of same colour. The triple of balls will then disappear.

You win if you manage to clear the board.
All setups are solvable, but you have to be careful which balls you click.

The other variants use different configurations which have to be eliminated, they use more balls and up to three configurations. While most variants are played on a 11x11 area, some monster variants have been added which use the large 21x21 board.

Note that there are several alternative piece sets available.
