    BetsRank Verdict

    Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

    Released on June 19, 2019, Wild Inferno dresses a nudging stacked wilds engine in a heavy metal hellscape: guitars, skulls, flames, a black-and-violet palette. A 5x4 layout with 25 paylines, 96.11% RTP, high volatility. The title's signature comes down to one nuance: in the base game, Nudging Stacked Wilds are wild stacks that shift to lock fully onto the reel, carrying a multiplier; in free spins, those same stacks turn sticky and stay in place for the whole sequence. The bonus opens with 5 scatter symbols for 5 free spins, retriggerable. On the ceiling, two figures matter: 20,000x advertised against 3,483x in simulation. RTP splits 63.87% base game / 32.24% free spins. No bonus buy.

    About Wild Inferno

    Released on June 19, 2019, Wild Inferno is the most rock proposition in PG Soft's catalogue of the period: electric guitars, skulls, flames and a black, midnight-blue and violet palette that cuts against the studio's dominant Asian imagery. The format is deliberately classic — 5 reels, 4 rows, 25 fixed paylines — with an official RTP of 96.11% and high volatility. The return split is rather favourable: 63.87% comes from the base game and 32.24% from free spins, meaning most of the value stays reachable without depending on the bonus. The heart of the gameplay is the Nudging Stacked Wilds. Concretely, stacks of wild symbols appear on the reels; when a stack is only partly visible, it nudges into place to lock fully onto the reel, maximising the number of lines covered. Those stacks arrive with a multiplier applied to the wins they complete. In free spins, the mechanic changes nature: the stacks become Sticky — they freeze in position for the whole run of free spins, multiplier included. Building up several sticky stacks across the sequence is the main route to the game's bigger wins. Bonus entry is demanding: you need 5 scatter symbols to open a run of 5 free spins, extendable via additional free spins earned during the bonus. On maximum potential, two figures coexist and we give both: PG Soft advertises 20,000x the stake, while the simulation records a maximum of 3,483x. The gap illustrates the difference between a theoretical ceiling and measured exposure. The bet range runs from 0.25 to 25, and no bonus buy is offered: the 5 scatters remain the only way in.
