You’ll always start with a Free Spins Key symbol on the bottom left of the reels, and it’ll gradually make it to the centre of the spiral if you keep playing for long enough - when this happens, and there are no more winning combinations or avalanches, you’ll activate Free Spins. There are four different Free Spins games to choose from - depending on how many keys you’ve collected in the key meter - all corresponding to one of the game’s random features.
