You start as Black playing White.

First select a bowl containing a stone with your colour (ie, a bowl containing a black stone if it is Black's turn) by clicking at the bottom part of the bowl. A blue indicator light will then signal that this bowl has been selected.

Now distribute the stones in the bowl (which we will call 'B') in the following way :
Move a stone from the bowl B into an adjacent bowl B2, then the next stone into a bowl B3 adjacent to B2, and so on.
You are allowed to change direction with every stone. You may even double-back into the original bowl (however, this is not allowed in variant 2).

Once you have emptied your selected bowl, you can capture a stone (by clicking it) if it is part of a 3-in-a-row arrangement, which means that 3 bowls are in a line, each carrying a stone of the same colour.
Captured piece will be stored in the player's 4x4 grid at the right border.

If there are no stones left to capture, click the NEXT button to pass the control to your opponent.

The player who first captures 16 stones wins.

Variant 2:
Here you are not allowed to distribute a stone to the bowl where the stone came from.

Note that there is an alternative board available.
