  • Super Free Spins: This bonus round is all about collecting more keys. These keys are awarded randomly when they appear on top of other regular symbols. Whenever you get a key, then the keys meter on the left side of the reels increases to one and can go up to 10 keys. You need to collect 2,000 keys to unlock the Super Free Spins.
