Dark Spiral Features & Bonus Games

There are plenty of bonus features, including a shattered bonus game and summoning symbols, which you can try out in free play mode.

Wild Symbols

The blood splattered W is the wild, and it substitutes for all other symbols on the paytable. If a wild lands directly above or below a summoning symbol, the summoning symbol can increase in size, expanding to cover the wild symbol.

Summoning Symbols

Summoning symbols can land in sizes ranging from 1x2 to 1x4. When they land, they will reveal a different stack of the same paying or wild symbols. The size determines the number of stacked symbols on each summoning symbol.

1x2 summoning symbols reveal 3-6 symbol stacks
1x3 summoning symbols reveal 5-9 symbol stacks
1x4 summoning symbols reveal 6-12 symbol stacks

Shattered Bonus Game

Land 3 or more FS scatter symbols to trigger 10 free spins with increased chances of landing summoning symbols.

Twisted Bonus Game

4 FS scatters trigger 10 free spins with the bonus mechanics of the shattered bonus. During this feature, summoning symbols will stick to the grid, revealing new stacks of paying or wild symbols.
