Hi there, and welcome to the Community @Richard_Burgess1 
At the moment, it’s impossible to let one user spin the wheel multiple times, but we have a request for this feature on the Wishlist. You can upvote this idea here -Allow users to spin the wheel multiple times
In the meantime, I’d be happy to check if there is a custom solution. Would it work for you if the prize will be reset every hour, or you need to reset it immediately?
