The Upgrading Wild feature also applies in the Crystallization Respin feature which is played when the Orange Crystal symbol lands on the hotspot in the middle of the central reel (reel 3) during the base game. You will then see the reels spin again with the symbols on the reels upgrading to the next highest-paying symbol (bar the wild as it’s the most lucrative).
New hotspots appear on reels 2, 3 and 4 with those symbols upgraded for bigger wins. If you get a wild, those symbols upgrade again. You can continue to get respins as long as Orange Crystal symbols appear in hotspots or there are no hotspots left.
