The kids in Unser Baumhaus want to build a treehouse in the garden, and plenty of nails and wood boards are available in the tool shed. To build the floor of a treehouse, you must first install four wood dice, then combine three building tiles in the proper order. Time is short, though, as dark clouds are covering the sky, signaling an oncoming storm. If players manage to finish at least one level of the treehouse and put a roof in place, they win the game together.
