House of Doom is the new heavy-metal slot that belts out omens of chaos, rage, pain and destruction on every head-banging game spin. Horned beasts and other occult symbols emerge from the deafening darkness and align to empower players along the game's 10 lines. The game includes a seer who may materialize to portend prize-winning combinations. If she happens to appear on the one reel randomly selected on each spin, she expands to cover that entire reel to foretell even more prize money and mayhem. The game also includes free spins with additional wilds plus a Skulls of Abyss bonus round that tempts players to select valuable skulls to add to their bonus prize until doomsday arrives.
