Mega Joker is a three-reel slot with five fixed lines and two distinct modes. Ordinary play can produce winnings that the player may then stake in Supermeter mode. Mystery wins and a progressive jackpot are separate elements of the design. Moving winnings into Supermeter means putting those winnings back at risk, so the two modes should not be described as a free upgrade. This compact classic format is also different from the larger Joker-themed grids supplied by other studios.
To compare related slots formats, read the rules of Dead or Alive 2 and Gonzo’s Quest.
The library also explains the difference between lines, ways and clusters to help put these mechanics in context.
