Trigger the free spins bonus if three or more scatters land on the reels, and you’ll receive ten free spins. You'll get the enhanced version if one of the scatters is on the extra reel.
The big difference in this bonus is that reactions have a progressive multiplier, with 1x being added with every reaction that occurs.
Before the spins begin, you get two picks from a series of doors. Each of these doors houses a win modifier, which could be Duplicating Wilds (wilds create new wilds), No Lower Symbols (all low-value symbols are removed from the reels), or the Double Multiplier (the reactions add a 2x multiplier instead of 1x).
