Rafter FiveNumber of Players: 1 6 In Rafter Five, you and your fellow players want to build as large a raft as possible but you want to end up being the only one who can board it. To start, stack the box top and bottom to create a base, then place the five wooden rafter pieces on the starting card on top of the base. On a turn, lift a rafter, place a raft card on the playing area, replace the rafter, then place one of your treasure chests somewhere on the raft
