Plunder is a deduction card game in which everyone is a pirate captain with a buried treasure. Players attempt to steal the hidden treasures of the other captains by figuring out the three landmarks that mark where each treasure is hidden. The first player to a treasure takes the largest share, while those who reach it second or third receive less. Keeping your treasure from being stolen is also worth victory points in the end. Find and steal the most treasures first to win in the end!
Players each get a random set of 3 cards (3 colors) each numbered 1-6: a unique combination. There are 3 decks of question cards matching these colors. On your turn, flip the top 3 questions; you may replace one of these by flipping the next card in that deck. All other players then respond AYE or NAY if they do or do not (respectively) have any exact matches. At any time players may guess the combo of any player by putting their guess into the treasure chest box. Each player in an n-player game may make n unique guesses.
After 15 rounds, guesses are revealed in the order they were submitted. If correct, that player will steal from that pirate's treasure: first 3, then 2, then 1. If no one steals your treasure, it's worth 6 to you; if they do, you lose the points they're taking. The player with the most treasure (their own, plus any stolen from others) wins!
