Just recheck again and yeah they have that term.
IMO, since they provided this information on their term & condition of their casino nothing you cant do right now since every service have their own rules and policy. I know was pitty losing 0.13 BTC but nothing cant do right now by following of their ToS since you are agree to all of them while you are decide to register.
Oh yeah about the ToS thing.
I found it's interesting ...
Take a look here
