Pros and cons of House of Doom 2: The Crypt

Game features of House of Doom 2: The Crypt

The online slot House of Doom 2: The Crypt uses a classic 5x3 layout with 20 fixed paylines. You need a combination of at least three identical symbols on adjacent reels from left to right.

The minimum bet is €0.20 per spin, and the game is playable on various devices, including smartphones and tablets.

Visually, the design stays true to the gothic aesthetic of the original but features refined graphics. The backdrop presents a ghostly mausoleum with eerie marble statues.

The sound design is also a highlight: an intense heavy metal soundtrack and haunting sound effects create an immersive atmosphere. Fans of hard rock music will feel right at home.

The slot includes nine regular symbols: five low-paying ones (playing cards from ten to ace) and four premium symbols—featuring two daggers, a poisonous flower, flickering candles, and a spiked skull.

The skull is the most valuable symbol, paying 1.5x, 2.5x, or 10x your stake for three, four, or five matching symbols.

Additionally, there are three female wild symbols in the base game, which substitute for all symbols except the scatter.

The standard RTP (Return to Player) of House of Doom 2 is 94.25%, which is fairly low for an online slot.

The Spirit Gate Feature

A Spirit Gate can randomly appear on any reel. If a wild symbol lands on it, the wild expands and triggers a re-spin with one of the following bonus features:

• Queen of the Damned: Adds Spirit Gates to all reels, allowing wilds to continue expanding, but no new re-spins are triggered.
• Fire Mistress: Grants a random multiplier of x2, x3, x5, or x10 on wins from the re-spin.
• Metal Priestess: Transforms all ritual relics into skull symbols.

Free Spins & Crypt Spins

Three scatter symbols on reels 1, 3, and 5 activate eight free spins, during which multiple Spirit Gates can appear per spin—boosting the chances of triggering bonus features.

If three more scatter symbols land during the free spins, you win eight Crypt Spins. Here, a fourth wild symbol, the Spirit of Unity, can appear and trigger a re-spin with all three bonus features activated simultaneously.

Free spins can be retriggered indefinitely by collecting three enhanced scatters.

Our verdict of House of Doom 2: The Crypt

House of Doom 2: The Crypt offers a second chance for a memorable gaming experience. While the original was solid, this sequel introduces improved graphics, higher win potential, and more diverse features.

The expanding wilds, re-spins, and special bonus mechanics add to the excitement—though they are difficult  to trigger.

This music slot is likely what Play'n GO originally envisioned for House of Doom. While it may not rock as hard as some others, it's packed with action.
If you enjoy gothic horror themes, you might also like Book of Madness by Gamomat.
