This game involves stacking stones. Stones are scattered on the ground. You can select a stone by clicking on it and move it. Use the mouse to stack the stone on top of a large foundation. Be careful not to let any stones spill out of the foundation, and keep stacking stones on the foundation until there are no more stones on the ground. Once all the stones have been stacked on the foundation, they will be destroyed, and you will have to stack more stones on the foundation again. Just keep repeating this. You will clear the level when you have stacked all the stones the specified number of times.
