Infernus – New (Backseat Gaming) Slot Review

Infernus: Slot Overview

Get ready to feel the heat, as developer Backseat Gaming takes players on a fiery journey to the depths of the underworld in Infernus. If your Latin is a little rusty, “Infernus” translates to “of the underworld” or “infernal,” which is exactly where this slot draws its inspiration from. While this might not be a place you’d want to end up in real life, as an online slot, Infernus presents an intriguing playground for those who enjoy high-impact features that don’t trigger constantly but can shake up the entire grid when they do.

The base game is set against a backdrop of smoldering ruins, bathed in red hues and drifting smoke. Interestingly, it’s not entirely subterranean—players can spot the moon and a starry sky peeking through the haze, adding a layer of mystery to the setting. Rather than going full demonic, as Hacksaw Gaming might have done with a theme like this, Backseat Gaming takes a slightly more stylized approach. The game’s chunky, animated visuals have a Beat the Beast vibe, combining fiery elements with bold, eye-catching artwork.

Infernus: Game Mechanics

Infernus plays out on a 5×5 grid with 19 fixed paylines, where winning combinations are formed by landing matching symbols across these preset lines. The game is highly volatile, scoring 5 out of 5 on the volatility scale, meaning big wins can occur, but they may not be frequent. Of the two RTP configurations available, the highest possible return-to-player percentage is 96.27%.

Betting options range from 10 cents to $/€100 per spin, catering to both casual players and high rollers. Additionally, four optional bonus modes can be activated for those looking to crank up the intensity.

When it comes to symbols, Infernus features nine regular pay symbols. Lower-value icons include 10 to Ace card royals, while premium symbols consist of a fiery cauldron, a crown or ring, a skull, and a phoenix. Winning combinations of five-of-a-kind (5 OAK) royals pay 1x to 2.5x the bet, while premium symbols deliver 5x to 20x the bet for a 5 OAK win.

Infernus: Special Features & Bonus Rounds

The core power of Infernus lies in its Wild Blocks, which can land both in the base game and across its two bonus roundsInferno’s Gate and Cerberus’ Rage. These features can also be directly accessed via the bonus buy menu for those looking to dive straight into the action.

Wild Blocks

Wild symbols appear in block formations of 2×2, 3×3, 4×4, or 5×5, displaying 2, 3, 4, or 5 Cerberus heads, respectively. Each head reveals a multiplier ranging from x2 to x100, which are added together to determine the total wild block multiplier.
