In Party Fun Pirate, players become pirates who take turns thrusting swords into a barrel that holds their black-bearded Captain captive, trying to see who can throw the most swords without harm. The game features various adventures including a Pop-Up Party mode, where up to four pirates take turns at poking holes in the barrel, and a Pop-Up Logic mode, where a single mate competes in a race against time to find the bad holes before time runs out. As an added bonus, players are able to unlock the ability to play the entire game with their own Mii character in the barrel.
