Demon Slot Guide

Demon is a branded rock music slot from Play'n GO based on Demon, the English heavy metal band active since the late 1970s. The game runs on a 5-reel, 3-row grid with 30 fixed paylines, with winning combinations of three to five matching symbols forming left to right from reel one. Bet levels start at 30p per spin.

The bonus structure is built around two wild symbol types — the wild mask and the wild amulet — each restricted to specific reels. Landing both simultaneously alongside specific positional conditions triggers the One Helluva Night! free spins round, with every free spin carrying a random win multiplier of 2x, 3x, 5x, or 8x. From within that feature, the Depths of Hell nested bonus can activate — awarding additional spins and carrying or doubling the active multiplier. The maximum win is 5,000x the stake.

Volatility and RTP

The RTP of Demon is 96.51%, sitting above the 96% benchmark. The volatility is high, and the maximum win is 5,000x the total stake. The high volatility profile reflects a structure where the significant pay potential is concentrated in the free spins round — particularly in combinations of high active multipliers and productive spin sequences — rather than base game payline wins.

At Slots Temple, under our Best Slots Odds Guaranteed commitment, we publish Demon at the highest available RTP of 96.51%, ensuring players have access to the best available version of the game's maths model.

How to Play

The controls in Demon follow Play'n GO's standard layout:

1. Use the bet box to set your stake, or access additional settings through the menu tab. The minimum bet is 30p per spin.
2. Open the paytable to review symbol values, the 30 fixed payline layout, and the full wild and free spins mechanics before playing.
3. Press the Spin button to begin each round. The 30 paylines are always active and cannot be adjusted.
4. Watch for the wild mask on reel 3 and the wild amulet on reels 1 and 5 — landing all three simultaneously triggers the One Helluva Night! free spins round.

How to Win

Demon uses 30 fixed paylines across a 5x3 grid, with winning combinations of three, four, or five matching symbols paying from left to right starting on reel one. Longer combinations pay at higher values than shorter ones for the same symbol. The two wild symbol types — the wild mask and the wild amulet — each have reel-specific landing conditions and carry mechanic functions beyond standard substitution, making their positional relationship to each other the primary driver of the bonus trigger.

Symbol Values

The premium symbol set features Dave Hill and four Demon album emblems, with Dave Hill as the highest-paying symbol at 10x the stake for five of a kind. The album emblem symbols pay at progressively lower values below the Dave Hill symbol. Stone statues, demons, gargoyles, and cross icons sit in the mid-value tier above the card rank symbols, which form the game's five low-paying positions. Card rank symbols appear with the highest frequency on the reels and contribute to smaller base game wins more regularly than the premium symbols.

Wild Mask

The wild mask symbol is modelled on the performance mask worn by Dave Hill and can only land on reel 3. When it lands on the central position of reel 3 — the middle spot of the middle reel — all Dave Hill symbols currently visible on the grid are converted into wild symbols for that spin's resolution. This can create multiple simultaneous wild positions across the reels depending on how many Dave Hill symbols are visible at the point of the wild mask landing in the centre spot.

Wild Amulet

The wild amulet symbol can only appear on reels 1 and 5. As a standard wild it substitutes for all regular paying symbols on the paylines crossing its position. Its primary structural role, however, is in combination with the wild mask — landing a wild amulet on both reels 1 and 5 simultaneously while the wild mask lands on reel 3 triggers the One Helluva Night! free spins round. The number of free spins awarded at the trigger depends on the mask's exact reel 3 position: landing in the centre spot awards 11 free spins, while landing elsewhere on reel 3 awards 6 free spins.

One Helluva Night! Free Spins

The One Helluva Night! free spins round activates when wild amulets land on both reels 1 and 5 alongside a wild mask on reel 3. Every individual free spin carries a randomly assigned win multiplier — each spin's multiplier is drawn independently from values of 2x, 3x, 5x, or 8x and applies to all winning combinations formed on that spin. The multiplier is assigned at the start of each spin rather than being fixed for the full feature duration, meaning multiplier values vary from spin to spin throughout the round. The active multiplier at any given spin is visible before the spin resolves.

Depths of Hell Nested Bonus

The Depths of Hell bonus can activate from within the One Helluva Night! free spins round when wild amulets land on reels 1 and 5 during the feature. Landing amulets on both reels simultaneously awards between 4 and 8 additional bonus spins, with the win multiplier that was active at the point of trigger carrying over into the nested bonus. If a wild mask also lands on the middle reel at the same time as the amulets, the additional spins awarded increase to between 6 and 10, and the active win multiplier is doubled for the nested bonus spins. The Depths of Hell bonus can retrigger — but the multiplier doubling is only awarded once per feature activation regardless of how many times the nested bonus triggers.

Demon Slot - Summary

Demon is a branded rock music slot built around a two-wild trigger system where the positional relationship between the wild mask and wild amulets determines both the base game substitution mechanic and the free spins entry condition. The One Helluva Night! feature's per-spin random multiplier and the Depths of Hell nested bonus give the free spins round two distinct layers of additional value potential beyond the standard allocated spins structure.

Context and Comparisons

Within Play'n GO's branded music catalogue, Demon sits alongside other band-licensed titles including Sabaton, Helloween, and Testament as a heavy metal-themed entry. It is structurally distinct from those titles — which use the expanding symbol free spins format — in that Demon's bonus is triggered by a specific wild combination rather than a scatter on reels 1, 3, and 5, and the free spins feature uses per-spin random multipliers rather than a single expanding symbol. The nested Depths of Hell bonus adds a mechanic layer not present in the expanding symbol entries, with the multiplier carry-over and doubling system giving the nested feature a direct mechanical relationship to the state of the outer free spins round at the point it activates.
