The pirates were sailing away from their latest raid, partying as only pirates can and counting their booty. Little did they know that one of the looted chests belonged to an old pirate sorcerer, who had sealed within it the powerful SINISTER TWISTER. It turned out to be a devastating problem not only for them, but also for the kraken fleet that was about to siege their convoy.

Sinister Twister adds components for a 6th player, a twister die and twister deck as well as curses and explosive bombardments.

The game is won, as in the original, by defeating pirates, and sometimes your competing krakens and stealing their treasure, however in Sinister Twister you have at least 5 more ways in which to mess with your opponents.
