Choose a pit on your side. Pick up all stones from that pit, then drop one stone into each next pit as you move around the board.
Your store is the large cup on your right. Stones in your store are your score.
Extra turn: last stone lands in your store.
Capture: last stone lands in your empty pit, and the opposite pit has stones.
Game end: one side is empty, then the other side sweeps remaining stones into its store.
