Ultimate Treehouse is a game of building and strategy for ages 7 and up. Each player starts with a beautiful blank tree mat and builds a treehouse full of fun classics. The first one to have 6 elements in their treehouse wins. Player on player cards allow you to slow down your opponents, helper cards will allow you advantages and disaster cards may slow you down. On your turn you draw cards and then can do one of three actions; build, play a card or draw again. To build you use material cards from your hand like lumber, nails and metal to build parts of the treehouse. The game ends when you have 6 elements in your treehouse- 3 required elements and any other three you choose.
