Instead after every spin any wilds that were present simply vanish and an entirely new screen appears that may or may not have new wilds on it. The slots here are strange in that they have recognizable advantage machines (like Ocean Magic Grand & Dragon Sphere) that do not contain the persistent state features (wilds that move up or down the screen). It's convenient to stop there on my way back from a card counting trip and hustle some slots to get some extra EV. I live near a group of slots only casinos that are all owned by the same Indian Tribe.
