What are the differences between Dplay and it? I've never tried Roobet, whilst Dplay does offer a non-custodial way of playing, which is something I value quite a lot as I've never enjoyed leaving my funds on the website for too long. Does Roobet offer anything similar?
Nope, Roobet is centralized and custodial as you will have to sign up in order to use it. I have never used Dplay but just a quick look at it shows that one has to sign up there as well, so I am not sure where the Non-custodial bit comes in.
Either way, if you don't like your money staying in the casino for too long, You can always withdraw it as soon as you make a win. Casinos are not supposed to be wallets.
