Acorn

Tribes of oak harvesters line a small valley, preparing to plant their trees in the fields below. They come to the valley in two waves, seeking to control the fields and to capture opponents' seedlings.Points are scored for controlling the planted fields. Most points at the end of the second round wins. Captured seeds are used as a tie-breaker. Two or three can play, using the same rules.
