Comes with 4 Treehouse cards with stands, Board with built-in spinner, and Colorform pieces. Player spins so the spinner points to one of the four Norfin Trolls. Player adds the matching troll to their Treehouse. If there is no matching troll or they already have the matching troll, play moves to the next player. The first player to fill their Treehouse wins.
