Your goal is to create a path that leads Earvin the sheep into the barn before any goats get inside!

Click on a tile to toggle it between grass and rock. When you're ready, click GO (or press Space) and the animals will start moving.

Earvin will always try to find the path to the barn that uses the fewest rock tiles. Goats will look for the path with the fewest grass tiles.

Keep playing to encounter even more animals. But your goal is always to make sure the Sheep get home first!
