How about the terms of the prizes from the 8Bet Wheel, is it free wager or players need to wager xx times of the winning prize before they are able to withdraw it? I think you should have a specific page to inform your players related to all your bonus, player's rank and its benefits, etc. I cant find it so I suggest it, but if you have it already please let me know where is it.
There is a wagering requirement for most of the prizes on the Wheel, but some don't have wagering requirements.
You can always check the exact wagering required for any Wheel prize (plus your progress towards wagering) and any other terms by going to the Account/Promos page when you are logged in.
