On a turn, a player picks up all the seeds in one pit and "sows" them to the right
(counter-clockwise), placing one seed in each of the pits along the way.
If you come to your store, then add a seed to your store and continue.
You may end up putting seeds in your opponent's pits along the way.
Play alternates back and forth, with opponents picking up the seeds in one of their pits and
distributing them one at a time into the pits on the right,
beginning in the pit immediately to the right.
When the last seed in your hand lands in your store, take another turn.
Capturing:
When the last seed in your hand lands in one of your own pits,
if that pit had been empty you get to keep all of the seeds
in your opponents pit on the opposite side.
Put those captured seeds, as well as the last seed that you just played on your side, into the store.
The game is over when one player's pits are completely empty.
The other player takes the seeds remaining in her pits and puts those seeds in her store.
Count up the seeds. Whoever has the most seeds wins.
