Have you ever dreamed of building a super awesome treehouse? Now it's time to live that dream! In Best Treehouse Ever, players compete to build the best treehouse in the neighborhood. Players will outfit their treehouse with the coolest rooms, all while making sure their tree doesn't tip over...and that their rooms are the most impressive at the end of the game. Building takes place over three weeks/rounds, and at the end of the third week the winner will be the player with the best treehouse ever! Each round, players use card drafting and spatial reasoning to add 5 new rooms to their treehouse. Players must pay attention to the other treehouses being built since they will take turns determining which types of rooms score for everyone at the end of each round.
