You’ll activate the Free Spins feature when you can land four or more of the scatter symbol, which is the hand that holds the lightning bolt. Four, five or six scatter symbols will give you 10, 15 or 20 free spins, respectively.
If, during the free spins, a wild horse lands on the reels, the wild will expand to fill up the entire reel, which will then trigger the Wild on Wild feature.
Lastly, three special coin symbols can appear during the free spins feature. You can fill up a meter with these coins, and you can win a special bonus prize when the meter is filled up.
