The goal is to clear the board of stones and not to bring down the whole pyramid. You remove the stones by finding matching pairs and clicking them. you can only remove stones that have no stones to the left or right.

You can choose one of five pyramids to start with. They consist of 234, 164, 114, 64 and 40 stones. The quicker you solve the pyramid the more points you get.

If  you made a mistake you can press "Back" button to undo the move. However, you many only get one move back and you will lose the points you earned for that move.

Try to solve the puzzle completely since in that case you will get bonus points.
