Pyramids and Flags is a game for 2 to 4 players with one Rainbow and one Xeno set of Treehouse pyramids to play it. Out of these pyramids, players put together flags of specific countries from all over the world. Apart from the pyramids and the pack of 36 goal cards, you do not need anything else. Move a pyramid to create a flag! Complete rules are available at the author's website, and at the Icehouse Wiki.
