The Joker Pro slot game is a 5-reel, 10-payline game casino classic in terms of its format and how it displays itself but this one takes on a traditionalist and simplistic feel that is sure to go down well with casino players that love to enjoy a slot game. The fact there are only 10 paylines on offer means punters don’t need to revise where icons need to fall in order to win. They can just sit back and enjoy the thrill of the reels turning as the Joker looks to make us laugh.
