Each time a Gloves symbol (Wild symbol) appears it will frame the reel position it appeared on. All framed positions stick for a 10-spin cycle after which they turn into Wild symbols to potentially create big wins. If you spin a Gloves symbol into a position that is already framed during the cycle this will increase the prize multiplier for that spin.
3 Ring of Riches Scatter symbols will trigger 10 Free spins. During the feature, all Glove symbols that appear will turn Wild and remain sticky until all Free spins have been completed.
