The types of chains you are allowed to place are given at the right border. Each chain consists of two or more pearls connected by a string. You have to use at least one of each tile (this will be checked by the program).

The orientation of the chain is not important. To place the longer 4-pearl chain, click the four target positions of the tile. To place the shorter 3-pearl chain, click the last position twice. (In general, when two types of different length are given, you click the last position of the shorter one twice to signal the end).

In between placing chains (i.e. when the counter at the right border is on zero), you can delete a chain by simply clicking its pearls.

You win when you manage to fill the given rectangle.

Expert level:
If shorter and longer chains are given, try to use as few short one as possible.
If two chains A and B of same length are given, first try to use as few as possible of type A, then as few as possible of type B.

There is also a Freeplay variant where you can create chains of any length. To finish the chain, click the last pearl again.

You can edit the given board by deleting or adding some blank tiles. Use Ctrl/c and Ctrl/v together with mouse click to add position markers.
