House of Doom separates its haunted mechanics into three routes. Hellgate highlights a reel for an expanding wild, House scatters open Doom Spins, and Skull symbols start a pick bonus. The useful way to review it is to follow each trigger rather than treat every supernatural symbol as part of one feature.
House of Doom at a glance
| Provider | Play’n GO |
|---|---|
| Genre / theme | Horror |
| Game type | Video slot |
| Reels / grid | 5 reels |
| Payout mechanic | 10 fixed paylines |
| Release date | 12 March 2018 |
| Main features | House scatters appear on reels one, three and five. Landing all three awards ten Doom Spins. During the feature, the House becomes an extra wild and between two and five reels are highlighted, always including at least one of those odd-numbered reels. A wild or wild House landing on a selected reel expands. Further wild House scatters add one spin per symbol when at least three appear, so the extension condition differs from the original three-reel base trigger. Skull bonus scatters use reels two, three and four and open the Skulls of Abyss pick game. Picks can reveal stake-based prizes, another pick, a House symbol or an ending value; the Skull does not appear during Doom Spins. This keeps the pick route separate from expanding-wild free spins even though a pick can award the Doom Spins feature. Death Dominion’s darker feature structure |
RTP and stake limits can vary by version and market. Check the information screen in the game you open. Maximum win is a ceiling, not an expected result.
How House of Doom sets up the base game
The game uses five reels and ten fixed paylines according to Play’n GO’s official launch material. The Seer is a wild that substitutes for ordinary symbols, and adjacent wilds can also form their own line result. On each spin, one reel is highlighted. If the Seer lands there, she expands across the reel. That rule depends on the highlighted position; a wild elsewhere still has substitution value but does not automatically become the Hellgate expanded wild.
The main feature rules
House scatters appear on reels one, three and five. Landing all three awards ten Doom Spins. During the feature, the House becomes an extra wild and between two and five reels are highlighted, always including at least one of those odd-numbered reels. A wild or wild House landing on a selected reel expands. Further wild House scatters add one spin per symbol when at least three appear, so the extension condition differs from the original three-reel base trigger.
How the mechanics interact
Skull bonus scatters use reels two, three and four and open the Skulls of Abyss pick game. Picks can reveal stake-based prizes, another pick, a House symbol or an ending value; the Skull does not appear during Doom Spins. This keeps the pick route separate from expanding-wild free spins even though a pick can award the Doom Spins feature. Death Dominion’s darker feature structure is a useful comparison, but House of Doom anchors its interactions to selected reels and separate scatter sets.
Configuration, strengths and limitations
The provider dates House of Doom to 12 March 2018 and explicitly lists Horror, music and IP themes. Its public page does not state RTP, volatility or maximum win, so those figures remain unknown for the reviewed configuration. The strength is that reel highlighting makes the expansion condition visible before symbols land. The limitation is fragmentation: the House and Skull scatter systems occupy different reels and lead to different modes, requiring careful distinction when reading the paytable.
House of Doom has a coherent rule once its symbols are sorted by destination. The Seer interacts with highlighted reels, the House leads to expanding-wild Doom Spins, and the Skull leads to picks. The resulting variety is stronger than a single generic free-spin feature, while also asking more from a first-time reader. Its best design choice is the visible Hellgate target. Its main drawback is that several similarly ominous symbols can be confused unless the reel restrictions and separate triggers are explained clearly.
