Dark Vortex offers some extra features. When you land 2 Vortex symbols on the reel you’ll receive 3 Vortex Spins where the reels expand to 5 rows high of the 3 increasing your chances of winning. With more vortex symbols landing the reels grow even bigger offering, up to 3125 ways to win. Once the reels reach their size you have a shot, at triggering the spins round.
In the spins round you’ll be asked to choose how free spins you want and how high you want the wild stacks to be. This choice is determined by selecting cards from a deck.
Alternatively you can activate the spins round using the Buy Bonus feature. By paying 800 times your bet amount you can access the bonus round without waiting for vortex symbols to appear.
