Infernus is a Backseat Gaming title released on February 26, 2025.

“Abandon all hope, ye who enter here”: we quote Dante precisely because Infernus promises to enter into real infernal settings, where all previous life takes or loses meaning. This is how this online slot machine presents itself, between magma and fire, Greek columns and stone: a truly sui generis background for a game. The intent of the manufacturer is not to make you perceive anything, but to intrigue and reveal the greatness of the game from the first spin.

Infernus - Slot Review

The release comes with a maximum RTP (return to player) value of 96.27%, a rather high volatility and a maximum win of x15,000 times the bet. It is a Scatter Pays type machine and the success rate is 26%. The sound is what we expect, epic and bold. From there, a few seconds after the start, an epic metal style ballad could reveal itself, it does not happen but with every spin we are truly impressed. The incandescent lava and the lapilli allow us to experience this title from underground.

You can entertain yourself completely free-to-play or with a minimum bet of $0.10 up to a maximum of $100. The grid is stylistically refined and the background says it all with 5 reels and 5 rows. The RTP is 96.27% but can vary based on operators and jurisdictions also contemplating the value of 94.23%. A further differentiation is given by the functions, in fact we can list the following levels (in the version with RTP 96.27%):

  • 96.21% with use of “BonusHunt FeatureSpins”.
  • 96.31% with use of “Hellfire FeatureSpins”.
  • 96.29% with purchase of “Inferno’s Gate”.
  • 96.25% with purchase of “Cerberus’ Rage”.

A high volatility production is often considered optimal by those looking for great emotions and potentially high winnings. This type is distinguished by the fact that it pays less frequently than low or medium volatility ones, but when it does, the winnings can be significantly higher.

From a strategic point of view, high volatility productions allow you to optimize your bankroll according to a long-term goal. If you are willing to face moments of gaming without immediate winnings, the reward can be much higher than other types.

Infernus

With a maximum win of up to x15,000 the bet, the release offers adrenaline-filled sessions for lovers of high volatility.

Theme

In the depths of darkness, where hope fades and the echo of judgment resounds eternally, Infernus slot machine is born, which does not simply evoke hell: it celebrates it.

The title itself recalls the immortal verses engraved on the threshold of Dante’s afterlife: “Abandon all hope, ye who enter here”. But in this digital hell, hope does not die: it burns, writhes and then rises again in the form of incandescent symbols. For players who love to tempt fate in the darkest places of the imagination, it is an irresistible call.

It is a symbolic descent into chaos, ruin and redemption of the perfect shot. The flames that lick the reels are those of inner restlessness, of the burning desire to overturn everything with a stroke of luck that seems impossible, yet throbs beneath the surface.

Those fascinated by myths, lost kingdoms and the literature of the damned will find a modern muse in this machine game. Every element is an allegory. One of the most appreciable qualities is its perfect optimization for all devices, both desktop and mobile.

Compatibility with iOS and Android operating systems allows every type of bettor to easily access the machine, without having to download additional applications or software. The responsive design of the interface ensures that every graphic detail – from the flames to the animations – is clear and clearly visible even on small screens. The controls are intuitive and adapted to the touch, so as to offer the same intensity even when you are on the move.

In addition, the lightness of the loading and the stability during the rounds, demonstrate the careful attention by Backseat Gaming to make it accessible and performing everywhere.

The symbols of the slot machine

In the Infernus machine by Backseat Gaming, the symbols evoke a journey through a mythological hell, with each icon contributing to the fiery atmosphere of the game.
Here is a detailed overview of the symbols, ordered from the most profitable to the least.

At the top we find the Phoenix, a mythical creature that is reborn from the flames. Its bright colors and sparkling animation make it immediately recognizable. Five phoenixes in line offer x20 the bet, a symbol that represents hope beyond the flames. Immediately after comes the Fiery Skull, an icon that combines death and power. It is dark and threatening, but promises great rewards: x10 the bet for five symbols.

Next, the Demonic Crown, probably belonging to some ruler of the abyss, pays x7.5 for a winning combination of five.

PROs & CONs of Infernus

PROs

  • Impactful setting and unique atmosphere
  • Excellent playability on all devices
  • Refined bonus modes and significant winning potential

CONs

  • High volatility not suitable for everyone
  • Paid bonus functions

The Burning Cauldron, from which spells and flames seem to be released, offers x5 the bet.

Then we have the poker cards: A (Ace) is the most valuable, paying x2.5 for five identical symbols. Next come K and Q, both with a maximum payout of x1.5, and finally J and 10, which stop at x1. These symbols, although more frequent, help to keep the session alive while waiting for more important shots.

The fiery Cerberus, Wild symbol, is the real infernal protagonist. This, not only replaces all other symbols to create winning combinations, but it comes in huge blocks from 2×2 up to 5×5, each with heads that reveal multipliers from x2 up to x100. It is visually impactful: a three-headed dog that grows and multiplies, occupying the entire grid and transforming the round. Five Wild symbols in a line pay x20, but the real potential lies in the sum of the multipliers generated, capable of making the winnings explode in an instant.

Finally, we have the Bonus symbol which is none other than the Scatter, very useful for the features we will talk about.

Slot machine bonus features

All the bonus modes of this release are very interesting.

Inferno’s Gate

It is the first of the two main bonus features that can be activated.
To access it, you need to get 3 Scatter symbols (with the flaming BONUS writing) during the base game. This activation grants 10 free spins, during which the power of Infernus intensifies.

During this, in fact, the probability of Wild blocks appearing increases significantly, that is, gigantic wild symbols that range from 2×2 to 5×5 and can include up to 5 multipliers.
Each of the heads of Cerberus in the Wild block reveals a random multiplier, from x2 to x100, and all these values ​​add up to form a single devastating multiplier.

Inferno’s Gate is the perfect feature for those who love pure adrenaline and want to see the entire grid ignite. The pace of the free spins may seem slow at first, but just one well-placed Wild block is enough to transform a spin in the abyss gate into a shower of burning coins.

Cerberus’ Rage

The second feature is Cerberus’ Rage, a round that perfectly embodies the ferocity of the mythological three-headed dog. It is activated when 4 Scatter symbols appear on the grid and also offers 10 free spins.

But unlike Inferno’s Gate, an even more brutal mechanic comes into play here: all Wild blocks become “sticky”, meaning they remain locked in their position for the rest of the feature. This means that, spin after spin, the grid can progressively fill up with huge multipliers. Furthermore, each new Wild block that appears can replace a smaller one, ensuring that the largest and most advantageous ones always remain on the grid.

Cerberus’ Rage is a “construction” feature, in which the tension builds, up to a potentially explosive climax.

Bonus Buy and FeatureSpins

For players who are impatient to immediately face the fiery heart, the Bonus Buy feature is available, a real shortcut to the hottest rewards.
Using the dedicated “BUY BONUS” button on the left of the grid, you can directly access the special modes, skipping the wait in the base game. But that’s not all: it also introduces FeatureSpins, which are purchasable spins that include guaranteed features. Each FeatureSpin has a cost calculated based on the selected bet, and remains active until the bettor decides to manually disable it.

There are four options available:

  • BonusHunt FeatureSpins, with an RTP of 96.21%, increases the probability of activating the bonus rounds at a cost of x2 the bet.
  • HellFire FeatureSpins, with an RTP of 96.31%, guarantees the appearance of wild blocks on each spin at a cost of x75 the bet.
  • Inferno’s Gate, purchasable to enter directly into the mode with 10 free spins and enhanced wilds (RTP 96.29%) at a cost of x100 the bet.
  • Cerberus’ Rage, direct access to the mode with sticky wilds (RTP 96.25%) at a cost of x200 the bet.

This feature is an invitation to “buy hell” for those who want to play without waiting, immediately facing the most explosive sections of the game. A way to transform each spin into a high-risk and potential gamble – a real pact with fire.

FAQs

The slot allows you to win up to 15,000 times your stake, thanks to the combination of Wild blocks and added multipliers.

Wilds appear in blocks from 2×2 to 5×5 and each Cerberus head assigns a multiplier that is added to the others in the block.

It is a high volatility slot: wins are not frequent, but can be very high. Ideal for those who prefer calculated risk.

Inferno’s Gate increases the frequency of Wild blocks, while Cerberus’ Rage makes them persistent on the screen, allowing progressive accumulations of multipliers.
