House of Doom is a 5-reel video slot with 10 fixed paylines, that invites you into the world of extreme style heavy metal music, where both music and lyrics intend to evoke a sense of despair, dread, and impending doom.
House of Doom includes a wild symbol (the Seer); a freespin scatter symbol in the main game (the House of Doom); a freespin scatter symbol during free spins (the wild House of Doom); and a bonus scatter symbol (the Skull). The wild symbol can substitute for any other reel symbol except scatter symbols to help comprise winning combinations. A combination of two or more adjacent wild symbols also constitutes a win when the combination appears along an active line.
One reel is randomly selected and highlighted on each spin. If the wild symbol lands on the selected reel, it will expand and replace all other symbols on that reel.
Freespin scatter symbols (the House of Doom) appear only on reel 1, 3, and 5. Landing three of these symbols in the main game awards a sequence of 10 free spins called Doom Spins. These free spins can be re-triggered by landing wild House of Doom symbols on reel 1, 3, or 5, up to the maximum win! Three or more wild House of Doom symbols on the reels in free spins awards one additional free spin per symbol. All bets and lines are the same as the game that started the feature.
House of Doom symbol will become wild House of Doom symbol during free spins, and acts as an extra wild symbol throughout the free spin feature.
During free spins, between two and five reels are highlighted. At least one of either reel 1, 3, or 5 is always highlighted. If a wild or wild House of Doom symbol lands on any of the selected reels, it will expand to replace all other symbols on those reels. Both wilds cannot land on the same reel.
Bonus scatter symbols (the Skull) appear only on reel 2, 3, and 4. Landing three of these symbols triggers the Skulls of Abyss bonus game. Pick skulls, one by one, to reveal hidden prizes. You can win cash prizes or trigger the above free spins feature. You may continue to select skulls for cash prizes until you reveal the House of Doom symbol or other end symbols. Pick again symbols are 1X, 2X, and 3X total bet prizes, while end symbols are House of Doom scatter, 5X, and 20X total bet prizes.
The bonus scatter symbol does not appear on the reels during free spins feature.
