Your funny flip-flop aliens land on the reels as wilds. They always expand to cover the entire reel and substitute for all paying symbols, bar the Free Spins scatter. They lock onto the reels for 1-4 spins, as recorded in the progress bar. If a new wild symbol lands where there is already an Expanding Wild with a multiplier, it will re-expand to cover the entire reel and take the current multiplier as its initial point.

Collect pink plasma ice cube patches to fill the progress bar above the reels. Patches may attach to all symbols (except wilds and Free Spins scatters), and you can collect a maximum of 20 patches on one spin. One milestone is reached after collecting 30 patches. The patches fill the progress bar of 4 milestones, each representing the number of spins each Expanded Wild locks onto the reels when they appear. When the progress bar fills full, it resets, and all additional patches fill the next progress.

When 3 Free Spins scatters hover onto the reels and you go to the bonus round for 10 free spins, the progress bar disappears. During Free Spins, wilds expand the entire reel where they show up. A wild will come with a multiplier. On every spin, the wild teleports one reel to the left and shrinks by 1 symbol height while its multiplier grows by 1x. When a wild becomes only 1 symbol in height or reaches the left-most reel, it disappears. The wilds may have 1x-5x multipliers, boosting the win way payout in every symbol combination they participate in—if more wilds participate in a combination, their multipliers add up.
