House of Doom is a 5-reel, 3-row, 10-pay line video slot featuring expanded Wild symbols, Free Spins, and a Bonus game.
On each spin in the main game, one reel is highlighted. Any Wild symbol landing there will expand to cover its entire reel.
When 3 Free Spin Scatter symbols (House of Doom) are visible after any spin in the main game, 10 Doom Spins will be activated. These free spins play at the same bet level as the spin which initiated this feature.
House of Doom symbols act as a Wild in addition to the normal Wild. During this feature, up to all 5 reels can be highlighted. The two Wild symbols coupled with additional highlighted reels creates the conditions where large paydays can be realized. As with the main game, when a Wild symbol lands in a highlighted reel, it will expand to cover the entire reel.
Also, when 3 or more House of Doom symbols land on the reels during Doom Spins, each symbol awards the player an extra spin. As the House of Doom symbols also serve as Wilds during Doom Spins, anytime one lands on the reels it is guaranteed to provide +3 additional spins. There is no limit to the number of spins that can be won.
Landing 3 Bonus scatter symbols (Skull) on reels 2 – 4 will trigger the Skulls of Abyss bonus game. The player is taken to a screen displaying 15 skulls. The player clicks them one-by-one revealing one of the following:
Pick Again Symbols: These bronze and gold symbols award the player a multiplier and an addition Skull selection. Play Again symbols are the 1x, 2x and 3x multipliers. 9 of the 15 symbols in this bonus are Play Again symbols. Correctly selecting Pick Again symbols can trigger the Doom Spins feature.
End Symbols: These symbols end the Skulls of Abyss bonus. The House of Doom, valuable elsewhere in the game, is a bonus-ending symbol here. However, other End Symbols, the 5x and 20x multipliers, are fairly valuable especially if selected after a few Pick Again symbols have already multiplied the win.
