Play N Go have a track record of producing some really innovative and compelling fully-featured online slots but this one is a little different. It`s a classic three reel game called Mystery Joker but while it is limited to those three rows of symbols it also includes a couple of bonus features to keep everyone happy. So Mystery Joker plays out over three reels and five fixed paylines but there`s no real theme behind the name. That`s not to say the graphics aren`t high quality because they certainly are and there`s a cheerful soundtrack to keep you company.
