Infernus (Backseat Gaming) Slot Review

Infernus: Slot Overview 

From the depths of digital hellfire emerges Infernus, a searing new release by Backseat Gaming, a studio operating under the Hacksaw Gaming umbrella. Known for its hard-hitting and often unorthodox game mechanics, Backseat brings a different flavor to the infernal theme—one driven less by intricate modifiers and more by pure, brute-force slot action. 

Set against a hellish backdrop with scorched skies and ominous shadows, Infernus is built on a 5×5 grid, played across 19 inset winlines, and comes armed with high volatility and a max win of 15,000x the bet. What sets this beast of a game apart are its Wild Blocks—oversized clusters of symbols that pack serious punch when they land, especially in the two bonus modes: Inferno’s Gate and Cerberus’ Rage. 

Infernus may not be rich in features compared to some of its Hacksaw cousins, but what it lacks in mechanical complexity, it makes up for in raw, visual force and knockout hits. It’s a slot that embraces its thematic power, delivering potential-packed rounds where one single symbol can turn the entire game around.

Design and Graphics 

Visually, Infernus hits a sweet spot between chaos and cartoon. The art style borrows from Beat the Beast, merging a deep red palette with chunky, bold graphics that look like they’ve been carved out of molten lava. The game’s setting feels appropriately doom-laden but never goes full horror—it’s more heavy metal album cover than nightmare fuel. The reel area is framed by gothic pillars, with flickering flames and a dramatic sunset providing a fiery ambiance. Symbols include classic hellish tropes like phoenixes, skulls, fiery cauldrons, and crowns, alongside your standard 10-A royals rendered in sharp, jagged fonts that look like they’ve been forged in brimstone. The design is consistent and punchy, clearly aimed at players who enjoy a heavier aesthetic without sliding into gore. 

Animations are clean and impactful, especially when Wild Blocks crash onto the grid. Whether it’s a 2×2 or 5×5 block, the entry is explosive and always draws attention. The game knows its vibe and sticks to it confidently.

Gameplay Mechanics 

At the core of Infernus lies the Wild Block mechanic, which delivers the game’s main thrills. These blocks of wilds appear in different configurations—2×2, 3×3, 4×4, and even 5×5—and come adorned with heads that carry individual multipliers ranging from x2 to x100. These are then totaled and applied as a single multiplier to any win involving that block. 

The base game uses 19 inset paylines, a refreshing switch from the typical ways-to-win format. Wins are calculated for matching symbols on designated lines rather than just adjacent reels, adding a layer of structure. You’re not just hoping for random cascades—there’s a sense of strategic placement here. 

Symbols pay modestly until you hit the premiums. A 5-of-a-kind royal pays 1.2–1.5x, while the best premium symbols can return 5x to 20x your stake for a 5-hit line. Wins can feel infrequent in the base game due to the volatility, but when Wild Blocks enter the mix, they’re often game-changers.

Sound and Music 

Infernus doesn’t try to reinvent the audio wheel, but its sound design is effective. The background music leans into the orchestral-metal hybrid genre, with ominous choral tones and pounding drums that evoke images of underground temples and ritual fire pits. 

Symbol clicks are weighty and satisfying, while Wild Block landings come with dramatic booms and fiery animations that crank up the excitement. During bonus rounds, the music intensifies, upping the adrenaline without becoming intrusive. There’s a slick polish to the entire soundscape that supports the theme without overplaying its hand.

Bonus Features 

This is where Infernus flexes its muscles. There aren’t dozens of modifiers or complicated progress meters—instead, the game brings four straightforward but effective bonus modes, with two of them triggered by scatters and the others accessible via the Bonus Buy menu. Wild Blocks 

Available in both the base and bonus game, these are the star attraction. Each Wild Block shows 2 to 5 heads, each carrying a multiplier. These are added together and applied to any winning lines the block touches. A 5×5 Wild Block with a combined x50 multiplier? That’s where the volatility spikes. 

Inferno’s Gate 

Triggered by landing 3 scatter symbols, this bonus awards 10 free spins with a higher chance of landing Wild Blocks. While the frequency of hits isn’t guaranteed, the feature is capable of delivering brutal hits when it connects. 

Cerberus’ Rage 

Triggered by 4 scatters, this bonus also gives 10 free spins, but with a twist: Sticky Wild Blocks. Once they land, they stay for the remainder of the round. And they can upgrade in size, replacing smaller ones—so with a little luck, things escalate fast. 

Bonus Buy Options 

For those who like to skip the wait: Bonus Hunt Spins (2x bet): 3x more likely to trigger bonuses. 

Hellfire Spins (75x bet): Guaranteed Wild Block hits. 

Inferno’s Gate (100x bet): Direct access. 

Cerberus’ Rage (200x bet): Premium bonus entry. 

These options give players plenty of control over how they want to engage with the game’s high-volatility punch.

Betting Options and Payouts 

Infernus accommodates a wide range of budgets, allowing bets from €0.10 up to €100 per spin. The maximum win potential sits at an impressive 15,000x the bet, making it a very attractive option for high-risk, high-reward hunters. 

There are multiple RTP configurations depending on region or bonus buys, but the default RTP stands at 96.27%, which is solid for a slot of this volatility level. With a hit frequency of 26%, wins will happen roughly once every four spins—though, as always with high volatility slots, those wins can vary wildly in size.

Conclusion 

Infernus by Backseat Gaming may not be as mechanically layered as some of its Hacksaw Gaming relatives, but that’s part of its charm. This is a slot that knows exactly what it wants to be—a hammer blow of raw intensity, driven by massive Wild Blocks and simple, powerful bonus modes. It’s the kind of game where one good hit can define your session, and that moment of potential lingers over every spin. 

The fiery theme, bold visuals, and sticky wild mechanics in Cerberus’ Rage elevate what might’ve otherwise been a one-note game into something punchy and memorable. The Bonus Buy menu offers plenty of flexibility, and with a 15,000x max win, Infernus is no lightweight. 

It may not appeal to players who crave feature-packed complexity, but for fans of slots that go big or go home, Infernus is a devilishly fun ride into the flames.
