Plunder Straits is a pirate-themed strategy board game where players sail around a map, entering harbors and trading cargo for gold. Each turn, players draw Plunder cards which can benefit them by giving them extra turns or more gold or by increasing their ability to defend, attack, or move. Players can also attack other players and take their cargo, gold, or abilities for themselves. The first player to bury 50 gold and keep their Jolly Roger flying win the game.
