Cascades. This popular feature sees winning symbols removed and those left on the reels dropping down to fill any gaps. New symbols appear from the top and cascades run without limit until there’s no new win.

Summoning Symbols. These black symbols with blood-red Japanese writing on them, can fill two, three, or all four rows on a reel and are key to the extra winning ways. 1x2 versions can reveal 3, 4, 5, or 6 symbols of the same type, which can include the wild that acts as others. The 1x3 Summoning Symbol transforms into stacks of 5, 6, 7, 8, or 9 matched symbols and you get 6, 7, 8, 9, 10, 11, or 12 symbols on a stack from the 1x4 version.

Summoning symbols expand to cover any wilds above or below them and when part of a win they remain in place as other symbols cascade until there’s no further win, revealing new symbols each time.

Free Spins. FS bonus symbols award the Dark Spiral™ online slot free spins features. Which level plays out depends on the number of triggering symbols, although each is made up of 10 initial spins, while two or three more FS symbols landing at once add two and four extra spins to the total.

• Shattered. Three FS symbols trigger this round where there’s a greater chance of Summoning symbols throughout.

• Twisted. Awarded via four bonus symbols, you get the likelihood of extra Summoning symbols and any that appear will lock in place for the rest of the feature, revealing new symbols on each spin.

• Tortured. At least two Summoning symbols land on the very first spin of this round, triggered by five FS symbols.

• An engaging backstory and creature design.

• Summoning symbols mechanism that makes it easier to win as they lock in place.

• Three levels of free spins with enhanced gameplay in each.

• Huge 10,000x maximum prize.
