Crystal Ball Hold and Spin Feature
Crystal balls act as bonus symbols here. However, they can only appear on the middle reel. Three is enough to trigger the Hold and Spin mechanic, so you’ll basically need to have them appear stacked on reel three.
During the feature, all crystal balls are held, while you’ll be given three extra free spins. The balls can now appear on all reels, and every time you land one, it will be frozen into place and reset your free spin counter. The idea is to land as many as you can because once no new ones appear, and you run out of spins, the feature ends.
Once it is all over, the values attached to each crystal ball are paid out. However, keep a lookout for the Golden Chests. These can appear on the first, second, fourth and fifth reels and can dish out epic wins worth anything from 100x up to 1,000x. You’re guaranteed to walk away with at least 20x your stake in the Hold and Spin round, though, which isn’t to be sniffed at.
