Infernus — RTP, volatility and max win

Infernus by Backseat Gaming is hellish horror in black and red: the devil rules over flames, skulls and burning card suits. Wilds carry multipliers and stick, and a giant mega symbol can take up a large part of the grid in one go.

The theme blends adventure with horror: the devil as ruler, skulls, fire and card suits as the lower symbols, all in deep black and harsh red. Five reels with five rows each form the 5×5 grid, carrying 19 paylines. Set your bet anywhere between €0.10 and €100 a spin. Backseat Gaming released Infernus on March 11, 2025, making it one of the newest titles in the hell range.

Infernus pays on fixed lines across its 5×5 field: there are 19 paylines, and a win needs adjacent matching symbols from the left on one of them. Wilds stand in for regular symbols, and since they carry multipliers, every line they join is boosted. The mega symbol covers three reels and three rows at once and counts on every line running through that block. Scatters are not tied to the lines and link to the free spins.

A scatter landing sets the free spins going, and that is where the wilds show their strength: as sticky wilds they stay in place over the following spins and keep their multipliers, so their effect can build from spin to spin. If the three-by-three mega symbol lands as well, it covers a big block of the grid and connects many lines at once.

The bonus bet lets you pay more per spin so scatters appear more often. Skip the wait with the bonus buy, which jumps directly into the free spins.

Since Infernus offers more frequent scatters for a higher stake, it is worth setting against other inferno slots with a bonus bet.

With a 15,000× cap, it outranks 87% of the catalogue. Volatility is high, yet roughly one spin in four still wins, as the hit frequency of 26% shows; the big amounts only come with sticky multiplier wilds in the free spins.
