How to play

Set your bet using the (+) and (-) buttons to increase/ decrease the amount, ensuring it is suited to you. Ready to face the vortex? Hit SPIN! There’s a load of features about to come your way…

WIN ALL WAYS: Win from 243 to 3125 ways depending on the number of Vortex Reels open. Game pays both from left to right and right to left.

VORTEX REELS: You’ll have 5 symbols instead of 3, including wilds, high pay symbols and orbs. Finding 2 Vortex symbols on adjacent reels converts them into Vortex reels for 3 spins. Find another Vortex symbol in this round and you get an additional Vortex reel! Changing the coin value while a Vortex reel is open will close all Vortex reels and resets any Free Spins gained in the portals. It is possible to open Vortex reels on reels 1 and 2 and a separate set of Vortex reels on reels 4 and 5. When this happens, 3 Vortex Spins are awarded for opening the first Vortex, and +4 Vortex Spins for the second Vortex (+2 spins for each reel). If all Vortex Spins have been bet without expanding to all 5 Reels, all Vortex reels are reverted back to the base game reels.

ORB COLLECTIONS: Orbs are only found on Vortex reels. When you open the Vortex, 2 Pink Orbs and 5 Blue Orbs are added to a collection. They reset every time a Vortex is closed. • Pink Orb Collection: each collected adds 1 wild to the stacked wilds on the 3 centre reels. They only land on reels 1 and 5. • Blue Orb Collection: each collected adds 1 extra Free Spin in Vortex Free Spins. They only land on reels 2, 3 and 4.

VORTEX FREE SPINS: If you open all 5 Vortex reels before winning out of Vortex Spins, unlocks Free Spins! One Free Spin is awarded for every Blue Orb collected. Vortex Free Spins have 5x5 reels and 3125 ways to win. The centre 3 reels all have stacked wilds. The stack is increased by 1 wild for each Pink Orb in the collection. Vortex Free Spins are played with the same coin value as the activating spin.
