Introduction to House of Doom 2: The Crypt
House of Doom 2: The Crypt is a casino slot from Play'n GO, once again paying homage to a legendary Swedish epic doom metal band. The studio's first tip of the hat toward Candlemass occurred in 2018 with the launch of the House of Doom slot, which was titled after the group's EP released that same year. Now, you'll have the 'pleasure' of returning to the morbid crypt in the sequel to meet Fire Mistress, Metal Priestess, Queen of the Damned, and Spirit of Unity, a group of devoted women bringing thrilling features. To elicit their dark powers, they'll need to walk through the Spirit Gate, which may randomly appear on any reel, after which you'll be rewarded with symbol upgrades, multipliers up to x10, or activating Spirit Gates on all reels during a re-spin. Reach the deepest corners of the haunted mansion to find Crypt Spins, during which all features combine for a maximised win potential that can reach 6,000x the bet.

Theme, Gameplay & Payouts
House of Doom 2: The Crypt is a video slot from Play'n GO with 5 reels, 3 rows, and 20 paylines. The game offers a wide range of bet options, allowing you to choose your stake from as little as a Min.bet of 0.20 up to a Max.bet of 100. The default RTP of 96.25% runs the math profile, which is in line with the industry average, although several lower variants are also available to the operators, including 94.25%, 91.25%, 87.25%, and 84.25%. We advise you to ensure which version your casino uses before starting your session. The balance between frequent low-value wins and rarer big hits should feel slightly tipped toward the latter because of medium-high volatility, while the maximum prize achievable within a single spin is 6,000x the bet.
House of Doom 2: The Crypt comes with an alternating design that changes the main scene depending on the currently active feature. You'll see the colour palette and the music transition between three different settings, each governed by one character: Queen of the Damned (green), Fire Mistress (purple), and Metal Priestess (blue). The soundtrack comes straight from the Candlemass band's albums, so if you're a fan, that's quite a treat to accompany you during gameplay. If you're ready to enjoy some doom metal music and the intimidating atmosphere of a dark crypt, the game's optimised design allows it to be played on any desktop, smartphone, or tablet.
The paytable is divided into two groups of symbols, which award payouts whenever you match at least 3 of them on an active payline while utilising neighbouring reels, starting from the leftmost one. The low-paying icons come in the form of red numbers and letters from playing cards, like 10, J, Q, K, and A. They award from 2x to 3.5x the bet for matching 5 on a payline. Images like crossed daggers, a flower, a triple candle, and a spiked skull represent the high-paying symbols. Those bring payouts from 4x to 10x the bet when you hit them on a payline spanning all 5 reels. In addition, there are four types of Wilds represented by the female characters and Scatters appearing as the game's logo.
Special Features & Slot Mechanics
What is the max win in the slot House of Doom 2: The Crypt?
You can win up to 6,000x the bet.
What features are available in the slot House of Doom 2: The Crypt?
The features are Spirit Gate & Wilds, and Free Spins & Crypt Spins.
Spirit Gate & Wilds
A Spirit Gate may randomly activate on any spin and appear on one of the reels. If a Wild lands inside it, it will expand to cover the entire column and trigger its respective feature, while awarding a re-spin.
Fire Mistress = awards a win multiplier of x2, x3, x5, or x10.
Queen of the Damned = adds Spirit Gates to all remaining reels.
Metal Priestess = transforms all high-paying symbols into the top-paying symbol.
Spirit of Unity (available only during Crypt Spins) = combines all three features at once.
Only one type of Wild is active at any given time, and it's indicated by the game's background colour. The active Wild changes after triggering Free Spins or Crypt Spins.
Free Spins & Crypt Spins
Two types of Scatters appear on the reels: regular and upgraded, which are generated by the regular ones landing in a Spirit Gate. Landing 3 or more of either at the same time triggers Free Spins or Crypt Spins, respectively.
During regular Free Spins, the feature that was active in the base game at the moment of triggering is also active throughout the bonus round. During this stage, more than one Spirit Gate can be activated per spin.
During Crypt Spins, at least one Spirit Gate is guaranteed on every spin, and the new Wild called Spirit of Unity becomes available, combining all other Wilds' features when triggered.
Final Thoughts on House of Doom 2: The Crypt
Play'n GO is arguably the only slot provider with such a deep connection with the music industry. The studio has collaborated with numerous bands over the years, releasing such hits as Testament, Sabaton, and Demon. The original House of Doom was their first step into this genre, and now we get to explore a dark sequel that carries the ominous spiritual journey further. Like most music-themed productions, the game comes with genuine music from the featured band, packed with several high-energy tracks that change between the base game stages and bonus rounds. Following the atmosphere of the predecessor, the second instalment comes with loaded, ominous vibes revolving around death and religious rituals. Everything feels more intense and elaborate than before, with four priestesses imbuing the setup with plenty of intimidating character.
The gameplay has evolved significantly as well, although it also maintained the core principles of the original, making the follow-up instantly familiar if you played the first part. In the base game, you'll still be hoping to land Wilds on the randomly highlighted reels to expand them, but this time around, you'll also get additional modifiers whenever that happens. Regular Free Spins provide a subtle boost, allowing for more Spirit Gates to hit the grid simultaneously, but the Crypt Spins are a real treat, not only because they guarantee at least one Spirit Gate on every spin, but because they introduce the fourth Wild, which is not available in any other part of the game. With the Spirit of Unity, you'll be able to trigger all other Wilds' modifiers at the same time for a maximised win potential, which is now more than double than before, reaching 6,000x the bet.
House of Doom 2: The Crypt competently builds on the mechanics of its predecessor while introducing a darker, more intense metal music atmosphere.
