Game Overview
House of Doom 2: The Crypt is a Play’n GO video pokie released on 11 March 2021. It uses a 5-reel, 3-row layout with 20 paylines and a dark music-horror theme linked to The Crypt. The checked version has a standard RTP of 96.25%, with lower operator versions also available at 94.25%, 91.25%, 87.25% and 84.25%. Volatility is listed as medium-high to high, and the max win reaches 6,000x total bet. Stakes run from $0.20 to $100 in the version checked. The base game uses Spirit Gate to create expanding Wild re-spins, while 3 Scatters on reels 1, 3 and 5 award 8 Free Spins. Crypt Spins can also trigger when 3 upgraded Scatters land.
Game Features & Mechanics
-
Twenty Paylines
Wins form on 20 paylines across the 5x3 layout. Matching symbols need to connect from the left, so the game stays line-based.
-
Spirit Gate Re-Spins
Spirit Gate can appear on a random reel. A Wild landing inside it expands across the reel and awards one free re-spin.
-
Free Spins Mode
Three Scatters on reels 1, 3 and 5 trigger 8 Free Spins. Spirit Gate stays active during the feature, giving Wilds more value.
-
Crypt Spins Bonus
Three upgraded Scatters can unlock 8 Crypt Spins. This round adds Spirit of Unity and brings the strongest mix of Wild effects.
Technical Specifications
-
Volatility Level
House of Doom 2: The Crypt is high volatility. You should expect quieter base spins, with stronger results tied to Spirit Gate, Free Spins and Crypt Spins.
-
RTP Explained
The main RTP version is 96.25%, but lower operator settings can apply. Check the in-game rules before playing for real money.
-
Bet Range
The checked version uses a $0.20 to $100.00 bet range. Casino currency may vary, but the 20-payline setup remains fixed.
Paytable & Symbol Values
House of Doom 2: The Crypt has 9 regular paying symbols. The Skull is the strongest base symbol, paying 10x for five, 2.5x for four and 1.5x for three. The Candles pay 5x, 2x and 1x, while the Poisonous Flower pays 4.5x, 2x and 1x. The Knives pay 4x, 1.5x and 0.75x. The lower symbols are A, K, Q, J and 10. A pays 3.5x, 1.5x and 0.4x; K pays 3x, 1.5x and 0.3x; Q pays 2.5x, 1x and 0.3x. J and 10 both pay 2x, 0.5x and 0.2x. Wins form on 20 fixed paylines from the left.
Special Symbols
Fire Mistress Wild
Fire Mistress substitutes for regular paying symbols. When she lands in Spirit Gate, she expands, triggers a re-spin and applies 2x, 3x, 5x or 10x to wins.
Metal Priestess Wild
Metal Priestess is a Wild with a symbol-upgrade effect. In Spirit Gate, she expands, gives a re-spin and changes Skull, Candles and Poisonous Flower symbols into Knives.
Queen of the Damned Wild
Queen of the Damned substitutes for regular symbols and controls the multiple-gate feature. If she lands in Spirit Gate, all reels receive Spirit Gate during the re-spin.
Spirit of Unity Wild
Spirit of Unity appears in Crypt Spins. When this Wild lands in Spirit Gate, the re-spin can use Fire Mistress, Metal Priestess and Queen of the Damned effects together.
Scatter Symbol
Three Scatters trigger 8 Free Spins. During Free Spins, Scatters can upgrade, and 3 upgraded Scatters award 8 Crypt Spins on top of remaining Free Spins.
Graphics, Animations & Sound Design
-
Graphics
House of Doom 2: The Crypt leans hard into gothic metal. The reels sit inside a dark underground setting, with candles, skulls, blades and spirit characters doing most of the visual work. The background changes with the active spirit theme, so the game avoids feeling static.
-
Animations
The strongest animations happen around Spirit Gate. A highlighted reel makes the next Wild landing easy to spot, then the expanding Wild takes over the full reel before the re-spin begins. Free Spins and Crypt Spins also feel clearer because the feature changes are shown directly on the reels.
-
Sound Design
The audio is built around the slot’s metal identity, not just generic horror effects. Each spirit theme has its own feel, and the music gives the bonus rounds more weight. The game still explains itself visually, so the sound adds atmosphere rather than carrying the rules.
-
Visual Feel & Interactivity
This is a busier Play’n GO pokie, but the screen remains readable. The main thing is learning what each spirit Wild does. Once that clicks, the re-spins, multipliers, symbol upgrades and Crypt Spins feel connected rather than random.

House of Doom 2: The Crypt on Mobile Devices and Other Platforms
House of Doom 2: The Crypt works well on mobile, but it needs more attention than a simple 20-line pokie. The base layout is compact enough for phone play, with 5 reels, 3 rows and clear paylines. The busier part comes from the Spirit Gate effects, because each spirit changes what the next re-spin can do. Free Spins and Crypt Spins are still readable on a smaller screen, but tablet and desktop make the expanding Wilds, reel highlights and theme changes easier to follow. We would use mobile for shorter sessions and a larger screen when playing through the bonus rounds.
-
Android
Android is fine for House of Doom 2: The Crypt, especially on larger phones. The reel frame stays clear, but bonus rounds benefit from more screen space.
-
iOS
iOS browser play keeps the symbols sharp and the controls simple. The Spirit Gate frame remains visible, even when the darker backgrounds change.
-
Tablet
Tablet gives the best mobile view. You can follow expanding Wilds, Scatters and re-spins without the screen feeling crowded during Crypt Spins.
-
Desktop
Desktop is the easiest option for longer play. The darker artwork, music theme and Wild effects land better when the full screen is visible.
Optimal Gameplay Tips
-
Use Stable Connection
EssentialA stable connection matters during Free Spins and Crypt Spins, because re-spins, expanding Wilds and bonus effects need to resolve without broken pacing.
-
Landscape Mode Recommended
RecommendedLandscape gives the reel frame more width. That helps when Spirit Gate highlights a reel and Wilds expand during the re-spin sequence.
-
Audio Settings
OptionalThe soundtrack is part of the metal-horror identity, but the rules stay visual. Adjust effects around your session rather than relying on sound.
-
Full Screen Mode
RecommendedFull screen makes the darker symbols easier to separate. It also helps you track Scatters, Spirit Gate frames and upgraded symbols during features.

About Play'n GO — The Developer Behind the Game
Play’n GO is one of the most recognised names in online casino games, with a large slot portfolio and a long record of building series around clear mechanics. The studio is known for games that work across desktop and mobile without making the rules feel hidden behind the theme. House of Doom 2: The Crypt shows that approach well. The game looks heavier than many Play’n GO releases, but the structure stays readable: 20 paylines, Spirit Gate, Free Spins, Crypt Spins and four spirit Wild styles.
The provider also has a strong history with music-themed and character-led slots, which explains why this game leans so hard into metal-horror presentation. The theme is not just background dressing. It connects to the feature design, with each spirit tied to a specific Wild effect. That makes the slot feel more deliberate than a standard haunted-house release. We like that the game has a strong identity without losing the basic payline format.
-
Large Portfolio
Play’n GO has hundreds of titles across slots and game series, giving the studio plenty of room to revisit and expand popular themes.
-
Mobile Focus
The provider builds games with mobile play in mind, so core controls and bonus features usually translate well to smaller screens.
-
Feature Identity
Many Play’n GO pokies are remembered for one clear mechanic, and House of Doom 2 centres that role on Spirit Gate.
Final Verdict
Why It’s Worth Playing
- Spirit Gate gives the base game more interest than simple line hits, especially when a Wild lands on the highlighted reel
- The three main spirit Wilds all behave differently, so re-spins can bring multipliers, symbol upgrades or extra Spirit Gates
- Free Spins are easy to trigger in concept, with three Scatters starting 8 spins and keeping Spirit Gate active
- Crypt Spins give the bonus game a stronger second layer, adding Spirit of Unity and combined Wild effects
- The 6,000x max win gives the slot more upside than many fixed-payline horror pokies
Things to Consider
- The feature rules take longer to learn than a basic Wild-and-Scatter slot, especially with four Wild types involved
- Lower RTP settings may be used by some operators, so the in-game rules should be checked before real-money play
- High volatility means the slot can feel slow when Spirit Gate and bonus rounds do not connect
Overall Rating
8.2
Bottom Line
House of Doom 2: The Crypt is a strong pick if you like horror pokies with more than a surface-level theme. The 20 paylines keep the base game familiar, but Spirit Gate gives the slot its own rhythm through expanding Wilds, re-spins and spirit-specific effects. Free Spins are useful, while Crypt Spins are the round we would really want to reach because Spirit of Unity can combine the main Wild powers. The game is not the simplest Play’n GO slot, but it rewards players who enjoy learning how the feature chain works.
