During Free Spins, any prisoner Wilds which land will stick in place for the entire feature, while a Wild on each reel will award an extra 2 Free Spins, unleashing huge win potential. If a second or third prisoner Wild lands on the same reel during Free Spins, they will also stick and transform all Wilds on that reel into x2 Wilds (for 2 Wilds) or x3 Wilds (for 3 Wilds).
