Yohoho! Puzzle Pirates is a massively multiplayer online game developed by Three Rings Design. The player takes the role of a pirate, adventuring on the high seas and pillaging money from roaming enemy ships (human or computer-controlled). The mechanics of Puzzle Pirates are driven by puzzles. For example, to effectively sail a ship, crewmates must play puzzles representing work at the sails for speed, pumping bilge water to remove it from the ship, and carpentry to fix any damage the ship may take.
