The River

The River (in the current base box) replaces the normal start tile, which goes back in the box. Start with the spring tile, shuffle the other river tiles face down in their own stack with the lake tile at the bottom, and place those first, one per turn. Each must continue the river, and the river can never turn the same way twice, as that would make a U-turn. Meeples are placed as normal, but never on the water, and the river divides fields.
