Yes. You will need a brand new account, but you can do so using the information from either your Rush Rewards or SugarHouse Play4Fun casino account.
Simply enter the screen name, email address and password that you wish to use, then select ‘I would like to register using my Rush Rewards Card’ or ‘I would like to register using my Casino4Fun account’ at the bottom of the first page. You will be able to login to that account and automatically create a real money online account using that information.
