Free Spins and Bonuses
The Free Spins symbol (star) needs to land on at least three different reels to trigger the bonus round. Depending on how many stars you get, you will be rewarded with 9, 10, 11, or 12 free spins, respectfully.
On the other hand, each spin that has less than three Free Spins symbols on the field has a chance of triggering the wild spawn feature. This feature simply puts a random number of wilds on the grid and gives you a chance to create awesome combos.
There’s also a Sticky Win feature, meaning that every winning cluster has a chance of sticking on the reels. This triggers an extra spin that gets re-triggered as long as the cluster keeps expanding.
