Jumbo Joker is a high-volatility fruit-machine slot from Betsoft, released in October 2017. The game uses two sets of three reels and five paylines, with a 95.00% RTP and a hit rate of 23.71%. Its layout combines a standard bottom reel area with a top reel feature linked to the JUMBO METER.
During normal play, wins of at least 20 coins on the bottom reels can transfer into the JUMBO METER. Players may then wager between 20 and 200 coins per spin on the top reels, where mystery prizes can appear. Landing three JOKER symbols on a payline triggers a mystery prize of 10 to 2,000 credits, and in 100- and 200-coin modes every JOKER symbol can award a mystery prize regardless of position.
The demo version is available to play for free, which lets users practice before playing for real money. Visuals follow a classic fruit-slot style with cherries, lemons, oranges, bells, grapes and a prominent joker character, while the interface includes the JUMBOMETER display, spin counter and standard bet controls.
