House of Doom 2: The Crypt (Play'n Go) Slot Review

House of Doom 2: The Crypt – Slot Overview 

Play’n GO’s House of Doom 2: The Crypt is a sequel to the dark and eerie House of Doom, taking the original’s doom metal-inspired theme and amplifying it with improved graphics, immersive sound, and expanded gameplay features. Released on March 11, 2021, this 5-reel, 3-row, 20-payline slot is heavily influenced by the Swedish doom metal band Candlemass, known for their gothic soundscapes and dark themes. 

With an RTP that varies from 96.25% down to 84.25% (depending on the casino version), high volatility (7/10), and a maximum win of 6,000x the bet, House of Doom 2: The Crypt offers an intense and unpredictable slot experience. The game features Spirit Gates, multiple wilds, free spins, and Crypt Spins, making it a worthy successor with more layered mechanics. 

Design and Graphics 

Play’n GO amped up the visuals in House of Doom 2, making it darker, more detailed, and richer in gothic imagery. The game takes place inside a haunted crypt, with flickering candlelight, misty pillars, and shadowy statues in the background, creating an ominous atmosphere. The symbols perfectly match the doom metal aesthetic: 

Low-Paying Symbols: 10-A, designed in a gothic script. 

High-Paying Symbols: Daggers, spiky skulls, flickering candles, and mysterious priestesses. 

Wild Symbols: 

Four types of wilds appear in the game, each with different modifiers. 

Scatter Symbol: The Crypt Scatter, which triggers free spins and Crypt Spins. 

The animations are smooth, with symbols glowing, flames flickering, and eerie mist rising from the crypt when a big win lands. This darker tone is a step up from the original, which had a slightly more traditional horror look. 

Gameplay Mechanics 

House of Doom 2: The Crypt sticks to a 5×3 reel structure with 20 fixed paylines. Wins are formed by landing three or more matching symbols from left to right. 

Spirit Gates: 

These mystical portals appear randomly on the reels. 

If a wild lands on a Spirit Gate, it expands, triggers a respin, and activates a unique modifier. 

Multiple Wilds: 

Each wild corresponds to a domain within the game and adds a different effect when inside a Spirit Gate. 

Crypt Spins: 

The ultimate free spins feature, leading to the biggest payouts. 

These mechanics add more variety and unpredictability, making each spin feel unique and engaging. 

Sound and Music 

The soundtrack is one of the game’s biggest highlights. House of Doom 2 stays true to its doom metal roots, featuring thunderous guitar riffs, haunting melodies, and atmospheric reverb. 

Candlemass provides the music, ensuring a truly immersive metal experience. 

Heavy bass and eerie whispers play in the background, adding to the game’s haunting ambiance. 

Winning combinations trigger electrifying guitar solos, making every big win feel even more epic. 

If you’re a metal fan, you’ll love the sound design. If you’re not, the intensity might be overwhelming, but it’s still a one-of-a-kind slot experience. 

Bonus Features 

Spirit Gates & Wild Modifiers

The Spirit Gate feature is one of the game’s most innovative mechanics. A Spirit Gate can appear on any reel. 

If a wild symbol lands inside a Spirit Gate, the wild expands, triggers a respin, and applies a special modifier: 

Queen of the Damned Wild – Adds Spirit Gates to all reels for the respin. 

Fire Mistress Wild – Applies a random multiplier (x2, x3, x5, or x10) to any respin win. 

Metal Priestess Wild – Converts all ritual relic symbols into the top-paying skull symbol. 

Free Spins Mode

Landing three Crypt Scatters on reels 1, 3, and 5 triggers 8 free spins. 

More than one Spirit Gate can activate during free spins, increasing the chance of triggering wild modifiers. 

If a regular scatter lands inside a Spirit Gate, it is upgraded to a Flaming Crypt Scatter, leading to Crypt Spins. 

Crypt Spins (Ultimate Bonus Feature)

Triggered by landing 3 Flaming Crypt Scatters. 

Awards 8 Crypt Spins. 

A new Spirit of Unity Wild appears, combining all three wild modifiers into one powerful wild. 

Crypt Spins can be retriggered indefinitely. 

Why This Feature is Important: 

Crypt Spins offer the biggest potential wins. 

Stacked multipliers, Spirit Gates, and symbol upgrades make it the most exciting part of the game. 

The 6,000x max win is most likely achieved in Crypt Spins. 

Betting Options and Payouts 

House of Doom 2 caters to all types of players, offering a wide range of bet sizes:
