House of Doom 2 The Crypt: Slot Overview

Play’n GO expands its rock-inspired catalogue with the darker, louder, music-driven slot House of Doom 2 The Crypt. The first House of Doom was built around the Candlemass track of the same name. Candlemass are often labelled an ‘epic doom metal band’ and have been active since 1984. They may not be universally famous, but they effectively helped shape doom metal, with the genre name tied to their debut album Epicus Doomicus Metallicus. With that much doom in the DNA, players who enjoy heavier sounds will likely connect more easily with the follow-up, House of Doom 2 The Crypt.

The most immediate difference between the two games is the noticeable visual upgrade, even though both lean heavily into shadowy, doom-soaked artwork – which is pretty fitting for the theme. A 5-reel, 20-payline grid sits front and centre, framed by crypt-like details such as eerie stone columns and low, moody lighting. The audio is equally on-brand, delivering a proper metal atmosphere while the reels are in motion. You can brave the crypt on any device, with stakes ranging from 20 p/c to $/€100 per spin, and a default RTP setting of 96.25%. While House of Doom 2 isn’t the most extreme volatility title Play’n GO has produced, its 7 out of 10 rating suggests it can still bite if you’re not careful.

The core mechanics are familiar enough. Hit three or more matching symbols from the leftmost reel to score a win. The lower 10-A card icons are styled in bold Gothic lettering, while the higher-paying symbols include daggers, a sinister-looking flower, wavering candles, and a jagged skull. If that lineup feels a little too unsettling, House of Doom 2 may not be your ideal spin. Up to 4 wild symbols show up in different forms, substituting for regular symbols as expected. Each pays 25x the bet for five of a kind, though some come with additional properties explained below.

House of Doom 2 The Crypt: Slot Features

House of Doom 2 features 3 separate domains, entered via specific wild symbols and Spirit Gates, each bringing its own set of modifiers. Alongside that, there’s a triggered free spins round and the Crypt Spins feature.

In the base game, a Spirit Gate may land randomly on any reel. When one of the wild symbols hits it, the wild expands and a respin is triggered, with one of the following modifiers applied:

• Queen of the Damned – places Spirit Gates on every reel for the respin.
• Fire Mistress – grants a random multiplier of x2, x3, x5, or x10 to any respin win.
• Metal Priestess – upgrades all ritual relic symbols into the highest-paying skull symbol.

Hit standard Crypt scatters on reels 1, 3, and 5 to trigger free spins. During this mode, it is possible to activate more than one Spirit Gate on any spin, which boosts the likelihood of setting off the modifiers listed above. If a regular scatter lands inside an active Spirit Gate, it upgrades into a Flaming Crypt scatter.

This opens the door to Crypt Spins, which can be triggered during a Queen of Damned respin, or during free spins once all 3 scatters have been upgraded – landing 3 Flaming Crypt scatters awards 8 free Crypt Spins. In this feature, the Spirit of Unity wild can appear, and if it lands in a Spirit Gate, it awards a respin with Fire Mistress, Metal Priestess, and Queen of the Damned modifiers all active at once. Lastly, Crypt Spins can be retriggered.

House of Doom 2 The Crypt: Slot Verdict

It’s not entirely obvious why players get to revisit the House of Doom for a second round, given the original didn’t become a huge mainstream success. Still, House of Doom 2 has the feel of a passion-led project, perhaps because the first game was conceived by Play’n GO COO Martin Zettergren. He didn’t just pitch the concept – he was invested enough to join the musicians in the studio to make sure the new track matched his intended direction for the slot.

The first House of Doom didn’t resonate as strongly as some other entries in Play’n GOs metal catalogue, even with its distinctive doom metal angle. The sequel, House of Doom 2, should land with a wider group of players, assuming they’re fine with their speakers getting a heavy dose of doom. It’s smoother overall, looks sharper, and the potential has been increased along the way. That said, House of Doom 2 isn’t a massive max-win monster, with top payouts capped at 6,000x the bet. It’s a respectable ceiling, but not the biggest among Play’n GO’s metal-themed slots if you’re chasing the largest numbers. That title still belongs to Testament for the moment.

Overall, House of Doom 2 comes across like the studio’s fuller realisation of what the original House of Doom idea was meant to be. There’s plenty of creepy appeal thanks to the richly dark presentation and the different priestess characters. It may not hit as hard as some of Play’n GO’s other metal slots, but it’s also far from being pushed into a tame, modern adult-rock lane.
