Expert’s Opinion
Personally, I found House of Doom to be one of Play’n Go’s more daring and rewarding titles. The theme is polarizing, but it’s executed with full commitment. The base game held my attention thanks to the Hellgate reel mechanic, and once I triggered Free Spins, the volatility showed its teeth in the best way. The RTP is a drawback, and I wouldn’t recommend this slot for beginners or low-budget players. But for someone with a bit of risk tolerance and an eye for thematic slots that aren’t afraid to go heavy on style, this one’s worth a few spins.

Introduction to House of Doom
House of Doom is Play’n Go’s take on the darker side of slot development, and they didn’t hold back. Released in mid-2018, this title marked a shift into bolder thematic choices, fusing occult symbolism, gothic artwork, and a heavy metal soundtrack into a slot that doesn’t cater to the average player. Everything in this slot feels deliberately designed to unsettle—from the color palette dripping in purples and blacks, to the presence of skulls, witches, and a cloaked Seer watching every move. It’s more than just visual flair though. This game introduces interactive bonus mechanics and volatile reel behavior that challenge even seasoned players. While the core of the game sits on a traditional 5×3 grid with 10 paylines, the layers of wild transformations, expanding reels, and pick-based bonuses push it into its own category of dark entertainment.
House of Doom Slot Provider
Play’n Go has built a reputation for bold, stylistic slot games that break from generic formulas—and House of Doom is a perfect example. While most providers shy away from horror, Play’n Go partnered with the Swedish doom metal band Candlemass to create a slot infused with actual band-licensed music and stage-themed imagery. The result is something that goes beyond visuals—it’s an audio-visual collaboration that reflects the developer’s creative ambition. Known for high-quality mathematics and well-balanced features, Play’n Go has delivered in both style and substance. Despite being released back in 2018, House of Doom still holds up against more modern releases, proving the provider's long-term consistency and willingness to take risks.

House of Doom Slot Gameplay and Mechanics
The core gameplay of House of Doom revolves around a standard 5-reel, 3-row setup with 10 fixed paylines. At first glance, it might feel like a typical setup, but there’s a lot going on beneath the surface. Every spin can trigger one of several mechanics that shake up the reels—literally. One of the game’s most notable base features is Hellgate, where one random reel is highlighted on each spin. If a Wild symbol lands on the highlighted reel, it expands to fill the entire reel, drastically increasing your chance of landing high-value combinations. Wins are calculated from left to right, and the game allows partial wins from combinations involving only wilds as well.
Here’s a breakdown of the base mechanics:
- 5 reels, 3 rows, 10 paylines
- Wild symbol substitutes for all but scatter and bonus
- Hellgate feature: random expanding wilds on a selected reel
- Seer Wilds pay even when not paired with standard symbols
- House of Doom scatters can trigger free spins
- Skull symbols on reels 2–4 can unlock a bonus picking game
What keeps the base game compelling is how often the Hellgate feature can shift the tempo. It's unpredictable but frequent enough to matter—especially when wilds start hitting multiple times per session.
House of Doom Slot RTP
House of Doom has an RTP of 94.10%, which places it noticeably below the industry average. However, this is not unusual for slots loaded with layered bonus mechanics and high volatility. The lower RTP is often Play’n Go’s way of balancing out massive win potential in the free spins and bonus rounds. It’s worth noting that this slot includes RTP ranges, meaning operators can technically configure it at different payout percentages. So players should always double-check the actual RTP of the version they’re playing. At its default setting, 94.10% can feel stingy during long sessions, but the structure makes it clear: this game is built for big, sporadic wins—not frequent small payouts.
House of Doom Slot Volatility
This slot doesn’t hide what it is—it’s high volatility from start to finish. If you’re hoping for low-risk spins and frequent wins, this game will punish you. House of Doom is designed to build suspense and then explode with dramatic rewards in short bursts. During our testing, we had several dry spells of 20+ spins with nothing to show—followed by a few spins that delivered 100x+ wins in quick succession. The combination of wild expansions, highlighted reels, and bonus rounds means that when it hits, it hits hard. But it also means bankroll management is absolutely essential. This volatility profile suits aggressive players looking for win spikes and doesn’t cater to those chasing consistent small gains.
House of Doom Slot Betting Range
House of Doom keeps things accessible with a wide betting range that caters to both low-stakes and high-roller players. The minimum bet starts at 0.10, while the maximum bet caps at 100.00 in your currency of choice—be it USD, EUR, or GBP. This clean and simple spread allows players to scale their bets based on comfort level. The 10 fixed paylines mean you don’t have to adjust lines, just your total stake. That said, due to the high volatility, larger bets come with heavier risk. Players who want to see the full potential of the game’s payout mechanics (especially the Free Spins and Skulls of Abyss features) should be ready to invest enough per spin to make those multipliers worthwhile.
House of Doom Slot Symbols Explained
Symbol design in House of Doom leans hard into its horror aesthetic. The high-paying symbols include a flaming skull, a pentagram, metallic roses, and demonic crosses—each rendered in sharp contrast with the dark background. The Seer, a hooded figure in purple, acts as the Wild symbol and can pay out directly in combinations of two or more. Even a line of two adjacent wilds qualifies as a win, which adds an extra layer of value compared to standard wilds.
The House of Doom symbol is the Scatter, appearing only on reels 1, 3, and 5 during the base game and transforming into a Wild Scatter during Free Spins. Meanwhile, the Bonus Symbol, a screaming skull, appears only on reels 2, 3, and 4 and is used to trigger the Skulls of Abyss bonus round.
Here’s how the symbols function:
- Wild (Seer): substitutes for all except Scatter and Bonus; pays even in partial combinations
- Scatter (House of Doom): activates Free Spins when three land
- Bonus (Skull): triggers Skulls of Abyss mini-game
- High-value symbols: Skull, Cross, Rose, Pentagram
- Low-value symbols: stylized card suits in sharp gothic fonts
The visuals are sharp and thematic, with eerie glows and animations that create a solid visual identity. The limited symbol pool makes payouts more predictable and keeps the game fast-paced.

House of Doom Slot Free Spins Round
Triggering the Free Doom Spins is a moment of pure chaos. You need three House of Doom symbols on reels 1, 3, and 5 to activate this round, which awards 10 Free Spins initially. But that’s just the entry point. During this mode, the same House of Doom symbols become Wild Scatters, meaning they function as additional wilds and also act as retriggers.
Here’s what’s active during Free Doom Spins:
- House of Doom becomes Wild Scatter
- Wilds expand on up to 5 highlighted reels
- Retrigger is possible—1 extra spin per Wild Scatter
- At least one of reels 1, 3, or 5 is always highlighted
During our playtest, we managed to trigger 30 Free Spins thanks to multiple retriggers and stacked wilds across highlighted reels. The payout during this round escalated fast due to the sheer number of expanding wilds landing across multiple reels. When 3+ reels are highlighted and a Wild lands on them, it can result in full-screen wild combinations, especially if you get overlaps between Seers and House symbols.
House of Doom Slot Features
Beyond the base game and free spins, House of Doom includes several cleverly integrated features that keep the slot from feeling one-note. The first is the Hellgate feature, which selects one reel per spin and gives it the power to turn a Wild into an expanding Wild. This adds real weight to every base game spin, especially when the highlighted reel is in the middle of the grid. Then there's the Skulls of Abyss bonus game, triggered by landing three skulls on reels 2, 3, and 4. It’s a classic pick-and-win round with escalating prizes, multipliers, and the potential to unlock free spins if you pick the House of Doom symbol.
Main features include:
- Hellgate Reel Expansion
- Free Doom Spins with Wild transformations
- Skulls of Abyss Bonus Game with cash prizes and retriggers
- Partial Wild wins even without full lines
- High variance payout system for massive spikes
It’s a strong mix of RNG mechanics and player interactivity, especially during the bonus game where every pick feels impactful.
