Players take turns placing pieces (either stones or towers) on the board. Stones threaten towers, controlling them. Towers weaken stones. The more towers next to it, the less effective the stone.

One well placed tower may free two others. One carefully positioned stone could win the game. There are 9 towers to vie for. You only need to control 4 to win, and you have 20 stones to do it with. Can you take the towers?
