Five-Tower Stacking Official Extension Rules
Treehouse Tower: You can call more than five cards. For each additional card you call, discard one of your Treehouse Tower cards into the discard pile in the center of the table.
Scrap Metal Tower: When you build this tower, take one card from your own discard pile and add it to your existing tower if you can build it.
Gravel Tower: You can place cards from the top or bottom, but only in one direction. This effect cannot be applied after a 0-tower is built.
Pairing Tower: For the remaining two types of towers, if there are towers with the same floor, each pair scores an additional 3 points at the end of the game.
