Inferno Mayhem — RTP, volatility and max win

Inferno Mayhem by PG Soft carries the inferno only in its name: the reels are about rock, music and dance, with skulls, a hat, a ring and shoes in blue and violet. Wins come from clusters rather than lines, and wilds with multipliers, a respin wild and sticky wilds in free spins drive the game.

The theme of Inferno Mayhem feels more like a rock stage than hell: music and dance set the tone, skulls add the dark touch, the hat, ring and shoes serve as premium symbols, and card symbols fill the low-paying spots. The stage is a 5×5 grid; the band plays for anything between €0.20 and €100 a spin. PG Soft released the game on March 2, 2026.

The 5×5 field has no fixed lines. A win forms when enough matching symbols build a connected group that touches horizontally or vertically. Wilds substitute for standard symbols and can complete or enlarge clusters, while scatters do not pay in clusters but start the free spins. Values per symbol and cluster size are listed in the in-game paytable.

In the base game wilds complete clusters, and some wilds carry a multiplier that raises the win of their group. The respin wild triggers another spin with the wild held in place. Random multipliers can boost a win on top.

Once scatters open the free spins, wilds stick to their positions and help build new clusters over several spins, while multipliers raise the wins of the round.

Because wilds in Inferno Mayhem carry multipliers and random multipliers join in, inferno slots with multipliers gathers other titles built on the same mechanic.
