Once they land, these characters turn into sticky symbols that expand to occupy the entire reel.

This feature can trigger randomly on any spin after your winnings are credited. Notably, when it activates, you’re assured of landing one of the feature’s four jackpot tiers.

If another wild lands during the free respin, it likewise expands and locks in place.
