Costume Party is a quick card game about bluffing, memory, and looking great. The goal is to score the most points among several rounds of play by wearing certain costumes. Each round, players have a hand of three cards and can play one of five corny costumes -- Vampire, Mummy, Robot, Ghost, Zombie, or one half of a Horse costume -- and each costume works a little differently. For example, you win 6 points if you and another player can coordinate a Horse costume... but lose 3 points if you go as just a Horse's bottom.
