Infernus (Backseat Gaming) – Review & Demo Play

Infernus Slot Review

Hope you are wearing something cool and loose fitting, because Infernus drags the action to a hot, crackling ruin on a 5x5 board with 19 inset winlines. Built by Backseat Gaming and delivered via Hacksaw's platform, it runs on a high volatility model and the top RTP setting is 96.27%. Stakes span £0.10 to £100. The pitch is simple: heavy Wild Blocks that do not land often but can flip a spin when they do. Four FeatureSpins and two free spin rounds sit on top.

Infernus Slot Theme, Layout, and Symbols

When it comes to the design of Infernus, the slot sits among ruins with smoke in the air and a moonlit sky above. The frame is pointy concrete, five reels by five rows, nineteen paylines, and audio that is almost bare save for clicks as symbols land. It looks agreeable enough, though pared back. The layout keeps things clear, and the board feels familiar if you have played Backseat's 5x5 setups before.

The paytable sticks to nine regulars. Low symbols are 10, J, Q, K, A, paying 1x to 2.5x for five of a kind. Premiums are the fiery cauldron, ring or crown, skull, and phoenix, paying 5x to 20x for a five-symbol line. Wilds substitute and can form their own five-of-a-kind worth 20x. The mix is basic, but the real punch sits with how Wild Blocks overlay and multiply line wins when they appear.

How to Play the Infernus Slot

Load Infernus, pick your stake with the + and - controls between £0.10 and £100, then hit spin. Wins land left to right on the nineteen paylines for three, four, or five matches. You can tweak the stake at any time. The base game is straight, so the flow is set your bet, spin, check the payline map, repeat. Progress comes from catching Wild Blocks or triggering a bonus via three or four scatters.

Infernus Slot Free Spins, Bonus Features & Bonus Buy

Wild Blocks drive the game. Wild symbols land in blocks of 2x2, 3x3, 4x4, or 5x5, each showing 2, 3, 4, or 5 hellhound heads. Each head reveals a multiplier from x2 to x100, and the values are added to create one block multiplier. That total applies to lines that use the block. Wilds stand in for any regular symbol, and a five-wild line pays 20x. These blocks can smother the grid when they size up.

Inferno's Gate triggers from three scatters for 10 free spins and an increased chance of landing Wild Blocks. Cerberus' Rage needs four scatters and also grants 10 spins, but here Wild Blocks are sticky. If a larger block arrives, it replaces a smaller one already in place. The tempo is classic Backseat brute force: quiet spells, then a block lands and the multiplier swings the outcome hard in a single spin.

Feature Buy options mirror the menu seen in other titles. Bonushunt FeatureSpins cost 2x bet and make each spin three times more likely to trigger a bonus. Hellfire FeatureSpins cost 75x bet and guarantee a Wild Block. You can also buy into Inferno's Gate for 100x, or Cerberus' Rage for 200x. Prices are punchy and the volatility stays high, but if you are chasing the top end, they give direct access to the meat of the slot.

My Experience Playing the Infernus Slot for Real Money

I set £1 spins for a 50-spin sample. The first ten brought three hits, each under stake. Then a dry run of about fifteen spins before a small line paid. Hit frequency was not great, and Wild Blocks stayed out of view. On spin thirty, a £1.80 result popped up. The last batch finally showed a block, but it did not connect. I finished with a top single hit of £6 and nothing bankable overall.

The features are not classically Hacksaw-esque, which I like in theory, but the base game feels barren until a block lands. When a big one arrives with a chunky combined multiplier, it is a sledgehammer effect that can flip a session fast. Without it, spins can chug along. That is the trade here: patience for power. I would use small stakes and wait for a sticky setup inside Cerberus' Rage rather than grind the base for long.

Infernus Slot RTP, Max Payout, and Volatility

Infernus runs high volatility with a top RTP setting of 96.27% and alternative lower profiles in some markets. The max payout is 15,000x the bet, reachable in the base, Inferno's Gate, or Cerberus' Rage. With the £100 ceiling, that tops out at £1,500,000. Stakes start at £0.10. It is a 5x5, 19-line layout, so line maths stay readable even when a Wild Block drops a large combined multiplier onto the board.

Infernus Slot Verdict and Recommended Games

I cannot point to much in the way of nuance. Infernus is sheer muscularity: wait for Wild Blocks, hope for heads that add up, and ride the hit. It can be spirit-crushing when the blocks are shy, yet it only takes one decent drop to send a spin flying. The 15,000x cap is on the table across all modes, and sticky blocks in Cerberus' Rage feel like the best route.

If you and I get on, I would steer you to try the demo first and bypass the base if it feels flat. I am not putting forward alternatives here; the take is simple enough. If the Wild Block concept speaks to you, give Cerberus' Rage a shot and keep stakes sensible. If not, there is no shame in skipping it. Either way, set limits and keep sessions short.
