About this Slot

Three scatter symbols trigger a Free Spins round awarding 8 spins. Wild symbols land with increased frequency during Free Spins. A +1 Spin symbol grants an extra spin within the bonus round.
Landing a Super Scatter upgrades Free Spins to Super Free Spins and adds 2 additional spins to the total. Super Free Spins are triggered by 2 scatter symbols plus 1 Super Scatter, starting with 8 spins. During Super Free Spins, all wild symbols transform into Golden Expanding Wilds, which increase multiplier-driven coverage across the reels.
