Sevens and Joker Wild
Introduction
Sevens and Joker Wild is a video poker game I noticed at the Macau Palace (a.k.a. Floating Casino) in Macau in August 2007. The game uses a 53-card deck, including one joker. As the title says, both sevens and jokers are wild. Either I wrote down the pay table incorrectly, or at 84.3% this is the worst video poker game I've ever seen.
