Inferno Star Slot Overview
Inferno Star is a retro-styled fruit slot from Play'n GO, released on 16 May 2019. Built on a 5x3 grid with just 5 paylines, it strips the experience back to basics. From a math perspective, you get a 96.38% RTP, high volatility, and a maximum win capped at 2,500x your stake.
I would describe this as a deliberately minimal game. No cascading reels, no multi-layered bonus rounds. The core attraction is the Raging Suns Re-Spin mechanic, which locks reels when Sun symbols land. That single feature carries virtually all the win potential beyond standard payline hits.
Symbols and Paytable
Fruit symbols make up the standard paytable; matches of 2 to 5 identical icons across any of the 5 fixed paylines count as wins. The Sun symbol is the highest-value regular icon and plays a dual role during the re-spin feature. Matching 5 Suns on a payline delivers the game's top standard payout.
Raging Sun acts as the Scatter. It only appears on reel 3, which severely limits trigger frequency. The numbers tell you this is deliberate: roughly 135 spins between bonus activations on average. With such a tight paytable structure and so few paylines, base game returns can feel slow. Not everyone will enjoy that pace.

Raging Suns Re-Spin and Gamble Feature
Landing a Raging Sun Scatter on reel 3 activates the Raging Suns Re-Spin feature. Every Sun symbol visible at the moment of triggering transforms into a Raging Sun, and its reel locks in place. All remaining unlocked reels re-spin. If a new Sun appears on any re-spun reel, it also transforms and that reel locks. Re-spins continue until either all 5 reels are held or a re-spin produces no new Suns.
Mathematically, the best outcome is a full lock across all reels filled with Suns. That scenario drives the 2,500x ceiling. Realistically, most triggers will lock 2 or 3 reels before the chain breaks.
Play'n GO's classic Gamble Feature is also present. After any win, you can guess a face-down card's colour to double the payout, or guess the suit to quadruple it. I'm not entirely sold on the gamble mechanic for serious play because it halves or quarters your EV per attempt, but it does add a layer of risk-reward for those who want it.

RTP, Volatility and Win Potential
Default RTP sits at 96.38%, which is competitive for a 2019 release with this level of simplicity. High volatility means sessions will swing. The 2,500x max win is modest by today's standards; many modern high-volatility slots push 10,000x or higher. Still, paired with a minimum bet of 0.05, the barrier to entry is low.
Bet range runs from 0.05 to 100 per spin. With 5 fixed paylines, each unit of bet covers all lines. Hit frequency data is not published by the provider, but a 135-spin average to trigger the re-spin feature implies fairly infrequent bonus hits. Base game wins on 5 paylines will be scattered and small; the maths model clearly funnels most of the return through the re-spin mechanic.
