The 'Wicked Feature' is randomly triggered at the beginning of any spin, where either reel 2, 3 or 4 will transform wild! Whenever this happens either through this feature or just by wilds landing, the 'Respins Feature' is triggered which will hold any reels fully stacked in wilds and respin the rest, with retriggers possibly giving you a shot at the ultimate 3 full stacks of wilds win! Wicked Winnings IV is a great game that built upon the winning formula of Wicked Winnings II, although now with more features.
Wicked Winnings IV is part of Wicked Winning Legends, which allows players to choose between that title and Wicked Winnings II, a player favorite.
