Demon Slot Overview
Demon is a 5x3, 30-payline video slot from Play'n GO, released on 26 September 2019 as a tribute to the British heavy metal band Demon. The format is deliberately old-school: fixed paylines, two wild types, no cascades, no Bonus Buy. The hook is the layered free spins with stacking multipliers and a soundtrack pulling tracks straight from the band's catalogue.
From a high-roller standpoint, this is a niche occult-rock title trading mechanical depth for atmosphere. I rate it as a mood piece more than a serious volatility instrument. The certified RTP of 96.51% is competitive, but the 5,000x ceiling against 5/5 volatility is the conversation that decides whether this gets bankroll time.
Symbols and Paytable
Top of the paytable is the Wild Mask at 16.66x for five on a payline, followed by Dave Hill the vocalist at 10x. Below that sit four album emblems: Golden Cross 8.33x, Gargoyle 6.66x, masked demon robot 4.16x and the lady statue at 3.33x. Card royals 10 through A pay a flat 1.66x for five.
Premium values are flat by modern standards. The vocalist symbol is the one to watch in the base game because the Wild Mask on reel 3 turns every Dave Hill on the screen into a wild, which is where the rare big base-game hits come from.

Bonus Features
Trigger requires Wild Amulet on reels 1 and 5 plus the Wild Mask on reel 3. You get 6 One Helluva Night free spins, or 11 if the mask lands dead centre. Each spin draws a random multiplier of 2x, 3x, 5x or 8x. The 8x is the one you want to lock in.
Inside the round, landing Wild Amulets on reels 1 and 5 triggers Depths of Hell Nested Free Spins: 4-8 spins, or 6-10 with the Wild Mask on reel 3. The active multiplier is locked for the duration. A centre Wild Mask doubles it, taking the cap to 16x. Re-triggerable, but the doubling applies only once.
No Bonus Buy here. Bonus Hunters used to skipping the grind have to earn this one organically, with hit frequency landing at roughly 105 spins per trigger. For serious players that means real bankroll commitment between features.
Bonus Buy Options
RTP, Volatility and Max Win
Certified RTP is 96.51%, slightly above the market average of 96%. Watch out for operator-configured versions floating as low as 94.51% on some platforms; verify in the in-game info panel before serious wagering. Volatility is rated 5/5, the maximum, so dead-spin frequency is significant.
Max win is capped at 5,000x stake. With a maxed-out 16x Hell Spins multiplier the math could organically run to 8,000x, but Play'n GO clipped it. For 5/5 volatility this ceiling is too low, the buy would be overpriced if it existed, and the reward-to-risk ratio is the slot's biggest structural weakness.
With a proper bankroll, I'd budget at least 150-200x your bet size before expecting to see One Helluva Night. Bet range is 0.30 to 90 per spin, so high-rollers get headroom but the absolute swings at 90 a spin are brutal between features.
Bankroll and Session Strategy
Demon punishes short sessions. The base game offers only the Wild Mask feature, so the cold runs between bonus triggers can drag and the dead-spin rate is high. I'd treat 0.30 minimum-stake calibration sessions as mandatory before scaling up; the demo replicates trigger frequency well enough.
For high-stakes runs, set a hard stop-loss in autoplay and accept that the 5,000x cap means a single hot bonus is the win condition. Stacking the 8x multiplier and locking it via Hell Spins is the only realistic path to anything close to ceiling. Without that lock-in, the math doesn't justify max bet.
