How House of Doom works

The Seer is the wild and substitutes for any symbol except the scatter. On each spin one reel is highlighted at random. If the wild lands on it, it expands to replace every other symbol on that reel. This is the Hellgate feature.

Doom Spins

House of Doom scatters appear only on reels 1, 3 and 5, and three of them award 10 free Doom Spins. In the round the House symbol becomes an extra wild, between two and five reels are highlighted, and three or more wild House symbols award one additional spin per symbol.

Skulls of Abyss

Three Skull symbols on reels 2, 3 and 4 trigger a pick game. You reveal skulls one by one for cash prizes of x1, x2 or x3 the total bet until you hit an end symbol: the House scatter, which starts the free spins, or a x5 or x20 prize.

What to look for in the demo

Watch the highlighted reel on every spin. A wild on that reel is the base game's main event.
