Match the falling pieces in such a way that you get three of a kind.
Three hexagonal stones fall down, you can move them sideways, you can rearrange their order, you can let them drop down. You try to get three or more stones of same colour in one row.
Or you can try to get six stones in a hexagonal pattern. If you get three of same colour in one row, they will disappear. If you get more than three in one turn, you will get bonus points for each stone. If you get six stones in a hexagonal pattern, they will disappear and so will the seventh stone in the middle, no matter what colour it is. A disappearing hexagonal pattern will give you some bonus time, too.
