Forest is one of the Expansion marked with "Easy" complexity: a good candidate to be among the first ones you try, or to play with inexperienced people.

Your goal is to build Forests all around your network, while keeping them separate from each other (a bit like Cities work in the core game; at the end of the game, you make 3 points for each group of at least 3 Forest tiles that are orthogonally adjacent).

Additionally, some Forest tiles also have pinpoints where you can place Lookout Tower pawns (which, like gondolas in the Canals Expansion, can be placed using any Placement token as a wild card, instead of placing the corresponding standard pawn). Each Lookout Tower is worth 1 point +1 for each orthogonal direction in which there is at least 1 Forest tile.

Like all expansions, the Forest Expansion comes with a few Objectives as well: for example, the Witch's House does not want to be in the same row or column as a Lookout Tower, while the Camping Ground must have at least 4 Forest tiles around it.
