Each player tries to make the largest pens with his own sheep inside by placing his own tiles. You can easily close small pens, or you can be ambitious and try to build large farms... but if you cannot enclose the fields, your sheep are likely to be eaten by the big bad wolves roaming in the nearby forests. Each player's animal is secret at the beginning of the game, but the soonest you reveal it, the more points you get. This edition includes the expansion.
