A 2x multiplier kicks in from the very first free spin and increases 1x more with every win during this bonus round. If you land three more scatters in the top row it re-triggers three more free spins.

The multiplier and re-triggered free spins are limitless, and it’s during this feature that you can end up bagging the amazing 28,000x big win.
