House of Doom

House of Doom Slot Review

A gothic mansion looms behind the reels, its spires and rooftop crosses picked out in purple light, with heaps of skulls piled in the corners and metal ones perched on the reel frame itself. House of Doom is Play’n GO‘s gothic-metal monument, and it’s the rare horror slot that stays disciplined: no wheel, no ladders, no second screen beyond a simple skull picker.

Everything hangs on one idea: an expanding wild, lit up before the reels stop. That single mechanic does the work that busier games spread across four features, and the numbers follow the same restraint. It runs a 5×3 grid, 10 paylines, RTP of 96.11%, mid-to-low volatility and a 2,500x ceiling. Where the studio’s House of Doom 2: The Crypt and Lordi Reel Monsters stacked on extras, this original trusts its one gate to carry the night.

The Base Game

Wins pay left to right across the 10 fixed paylines, and only the highest combination on each selected line counts. It’s a classic five-reel setup with nothing exotic in the win mechanics. The blue-faced woman is the wild, substituting for every symbol except the scatter.

The symbol set dresses the reels in the same iconography as the artwork: ram skulls, roses, chained bolts and pentagrams sit above the card royals, and all of them pay as multiples of the total bet. The full paytable:

• Ram skull: 0.4x, 4x, 20x, 70x for two, three, four, five
• Red rose: 0.3x, 3x, 15x, 50x
• Crossed bolts with chain: 0.2x, 2.5x, 12.5x, 40x
• Silver pentagram: 0.2x, 2x, 10x, 35x
• A, K, Q: 0.7x, 3.5x, 10x for three, four, five
• J, 10: 0.5x, 2.5x, 7.5x
• Wild (blue-faced woman): 0.5x, 5x, 25x, 100x
• House of Doom scatter: 0.5x, 5x, 25x, 100x

Both the wild and the scatter sit at the top of the paytable, each paying up to 100x the total bet for five. That makes them the richest symbols on the reels, and three scatters anywhere set the free spins in motion.

Two of a kind is all the top four symbols need to pay, which thins out the dry stretches between bigger hits on a mid-to-low volatility game. The royals need three, and they pay the least. Nothing here breaks the mould; the interest all sits in what the wild and scatter do rather than what they pay.

Hellgate

Hellgate is the modifier that runs on every single spin. One reel is randomly selected and lit up, and any wild that lands on that highlighted reel expands, replacing every other symbol on it. A single wild in the right place becomes three stacked ones.

It’s a simple idea with real consequences on a 10-payline grid. An expanded wild covering a full reel turns several lines wild at once, so the highlighted reel is the one to watch on every spin.

What it doesn’t do is guarantee anything. It only pays off if a wild happens to land on the chosen reel, which keeps the modifier honest. On the spins where nothing connects, it’s just a lit reel.

Doom Spins

Landing three House of Doom scatter symbols anywhere on the reels starts the feature with 10 free spins. During the round, the Hellgate principle widens: between two and five reels are highlighted on each spin, and both the wild and the wild House of Doom scatter expand on any of them.

There’s a second twist. The House of Doom scatter itself turns wild during the feature and substitutes for every symbol, so the symbol that triggered the round becomes part of the winning machinery inside it.

That conversion matters more than it sounds. The scatter now expands on highlighted reels like any other wild, and it feeds the retrigger meter at the same time, so a single highlighted reel can carry a symbol that pays, stacks and extends the round all at once. Retriggers work per symbol rather than per set:

• Three or more wild House of Doom symbols award one additional free spin per symbol
• Landing four at once is four extra spins; landing five is five
• No cap on the number of retriggers is stated

Skulls of Abyss

Three scatter symbols also open the bonus game. Fifteen skulls appear on screen and you pick them one at a time, each revealing a hidden prize. Behind the skulls sit:

• Cash prizes, added to the total win amount
• Entry to the Doom Spins feature
• Pick Again coins in 1x, 2x and 3x values, which keep the picks coming
• End symbols, shown as 20x and 5x coins
• The House of Doom symbol, which also ends the round

The round runs until you uncover an End symbol, so every pick is a bet on there being more behind the next skull. The 20x and 5x End coins soften the landing: they stop the picks but pay you for the trouble, which means a short run isn’t necessarily a dead one.

A run of Pick Again coins can stretch the feature out before the end arrives, and everything collected in cash is added to the total win amount. Whether the bonus can be retriggered within itself isn’t stated; what’s certain is that the Doom Spins it can hand over are the real prize of the round.

Our Honest Verdict

Overall Rating: 7.7/10

Spinning here is a quiet, steady ritual: watch the lit reel, hope a wild lands on it, repeat. That’s the whole ritual, and honestly it holds attention better than it should, because every highlight is a small promise the game might actually keep. The mansion stays brooding throughout, and the pace never turns frantic.

Doom Spins are the clear strength. Everything the base game teaches you gets multiplied at once: two to five lit reels, a scatter gone wild, and retriggers that pay per symbol rather than per set, so a good round keeps feeding itself. The weakness is the ceiling. With 2,500x as the top prize and mid-to-low volatility, the ceiling sits well below where the gothic-metal atmosphere points, and the Skulls of Abyss picker is a thin appetiser whose best outcome is leaving for the free spins.

This is one for players who enjoy a single mechanic done properly and frequent, modest returns, with the artwork as the main event. Anyone after max-win chases or a feature every third spin will find the mansion’s corridors too empty. For a slower, steadier kind of haunt, the lights are on and the door’s open.
