Game Features

Expanding Reel Feature

Three Mystic Ball symbols on reel 1 trigger the Expanding Reel Feature and add up to 3 extra rows in the base game and up to 5 extra rows during the Free Spins feature above reels 2-5. If only one or two Mystic Ball symbols appear on reel 1, the reel will nudge to add the extra Mystic Ball symbols to fill the reel, which will then trigger the Expanding Reel Feature.

During the feature, each Mystic Ball symbol on adjacent reels, beginning from reel 2, will award the prize displayed on it. Mystic Ball symbols on reels 2 to 5 can consist of credit prizes up to 20x the total bet and/or jackpot prizes (Mini, Minor, Major and Mega).

The Expanding Reel Feature occurs more frequently during the Free Spins.

During the Expanding Reel Feature, only Mystic Ball prizes are awarded. All other “way pays” (regular combinations and symbols) are not evaluated.

Wheel Feature

Three Scatter symbols on reels 3, 4 and 5 trigger the Wheel Feature where 1 spin of the wheel is awarded. The wheel awards either Free Spins or a Jackpot.

Free Spins

Free Spins are triggered during the Wheel Feature and award up to a maximum of 20 Free Spins. Scatter symbols do not appear during the Free Spins.
