HOW TO PLAY:
You have to remove all the stones from the grass.
Select stones moving your finger across them.
Selected stones have to be in straight line (row or column), it's no problem with some distance between them, but number of selected stones must be the same all the time (magic number), no more, no less!
Confirm selection by touching stones again to remove them.
Think and plan, which stones should be removed first, because sometimes it is very hard to find right sequence.
It has nice animations, many levels from easy ones to pretty hard.
You have to think. Think a much, it is many hours of thinking in this game.
