On any spin the booster spin has a chance to trigger. When the booster spin is active you are more likely to land 3 scatters than any other spin. The booster spin is not active in free spins. If 3 scatters land on any spin, then the chance wheel will be triggered. The chance wheel can award the following multiplication of the bet staked: 5, 7, 22, 33, 55, 77, or 777. The chance wheel can also award free spins.
Free spins are awarded via the chance wheel. 12 initial free spins are awarded and more can be rewarded during any free spin. Landing 1 scatter awards +1 free spin. Landing 2 scatters awards +2 free spins. Landing 3 scatters awards the chance wheel, where the same awards are active, as well as +5, +10 or +20 additional free spins.
During the free spins feature, if a wild lands on any reel it will stick and remain on the reel for the next 2 free spins. Over the course of the next 2 free spins it will spread to the remaining symbol positions on the reels; moving 1 adjacent symbol position for each free spin. Wilds that stick in the middle position have a 50% chance to spread to the top or bottom symbol position.
