The crypt wobbles into view with ruined architecture and three distinct spirit entities that mean business — Fire Mistress, Metal Priestess, Queen of the Damned. Skulls vanish and reappear, candles hum in the darkness, poisonous flowers cascade across the reels, mystical knives pop into frame. Deep purples, blacks, and amber accents create genuine atmosphere without compromising gameplay clarity. Desktop and mobile both hit the same visual fidelity. Play’n GO’s production standards zap through every frame.
Access the demo through your mobile or desktop — whichever fires up best on your connection. Watch this unfold:
Premium symbols pack serious value — Knives, Skull, Candles, Poisonous Flower all surge up the payline. Multiple Wild variants fire up: Spirit of Unity, Damned, Metal, and Fire representations. Scatter symbols crash through exclusively for bonus triggers. Card values from 10 to Ace provide the baseline:
Six distinct feature categories fire across this slot — each one creates its own chaos and win escalation path. Layered mechanical depth means every activation chains into potential follow-ups. Here’s the complete breakdown:
| Feature Name | Activation Condition | Mechanical Effect | Win Impact |
|---|---|---|---|
| Spirit Gate | Random reel highlighting during base game or Free Spins | Expanded Wilds crash across entire reel, triggers one free re-spin automatically | Payline hits surge through expanded Wild coverage |
| Fire Mistress Multiplier | Appears during Spirit Gate re-spins | Multiplies all wins by x2, x3, x5, or x10 values | Individual wins escalate dramatically during active re-spins |
| Metal Priestess Upgrade | Fires via Spirit Gate mechanic interaction | Converts Skull, Candles, Poisonous Flower into higher-value Knives | Winning combinations pop higher through symbol elevation |
| Queen of the Damned Gates | Activates during consecutive re-spin phases | Multiple Spirit Gates crash across all reels simultaneously | Multiple Expanded Wilds vanish and cascade — re-spins chain together |
| Free Spins Round | Land three Scatter symbols in base game | Eight Free Spins with Spirit Gate active every spin; Scatters upgrade throughout | Gameplay extends while feature activation potential stays hot |
| Crypt Spins Bonus | Collect three upgraded Scatter symbols during Free Spins or base game | Eight additional Free Crypt Spins explode; Spirit of Unity Wild fires; landing it in Spirit Gate triggers re-spins with all three spirit bonuses applied | Highest win potential through combined feature frenzy |
Medium-to-high variance roars through this slot — re-spins accumulate and multipliers chain into x10 hits during Crypt Spins. Standard play wobbles at moderate variance baseline, but watch out — feature convergence can burst sessions wide open. UK players should check licensed operator specifications for regional RTP compliance values.
Spirit Gate fires the foundational system — every spin type across base game and bonus rounds activates it. Random reel highlighting keeps genuine uncertainty alive about which spin triggers Expanded Wilds. These cover entire reel height and crash into automatic re-spins with zero additional stake. The core loop stacks consecutive spirit appearances, chaining multiple free re-spins from single initial spins. Symbol upgrades transform specific symbols into higher-paying variants based on active spirit interactions. Scatter upgrade mechanics operate exclusively during Free Spins — symbols progressively transform toward upgraded states required for Crypt Spins unlock. This creates genuine progression where initial Free Spin rounds set conditions for superior Crypt Spin outcomes. Spirit of Unity Expanding Wild mechanic available during Crypt Spins operates as progression reward providing combined spirit bonuses. Landing it in Spirit Gate during Crypt Spins triggers re-spins with Fire Mistress, Metal Priestess, and Queen of the Damned bonuses simultaneously zapping into wins.
House of Doom 2: The Crypt continues the House of Doom franchise roar established through earlier Play’n GO releases. Three powerful spirits drive the narrative through character interactions and thematic consistency. Franchise continuity runs throughout Play’n GO’s catalogue — these character-driven mechanics represent solid positioning within their broader slot portfolio.
