Grimm Forest is a 2-4 player strategic game of Hidden Movement, Resource Gathering, and House Building. It is a medium weight game that plays in approximately 45-60 minutes.

During the game, players will play cards secretly to move to various Location boards where they attempt to gather resources. Using their deduction skills and a hand full of Fable cards, players attempt to guess each other's plans and make the most of their actions while disrupting the other player's plans.

After resources are collected during the Gather Phase, players will enter a Building Phase where they can use those resources to build Wood, Straw, or Brick Houses. Whenever a player builds a Wall Section on one of their houses, a helpful Friend from the nearby forest comes to lend a hand. Players may choose to accept the help of that Friend, but occasionally it makes more sense to send that Friend to a different player, sometimes discarding their current Friend in the process.
