I found this casino on Bitcointalk and tried it. Then now I have problem with them and after search on Casino Guru I see a lot of cases "money frozen for 2-3-4 weeks". If it's not scam... I hope they will pay at least after month.
They are not scammers which other posters have already mentioned, but they aren't the best when it comes to resolving complaints quickly which is why their reputation took a hit recently.
If you didn't do anything wrong, you will 100% get your money though it could take months which is why you probably need to strap in for a long ride.
Exactly what other don't want to understand because they are sponsoring the casino, you cannot leave without ANSWERS for months people and act nonchalant, thats not how this business works ( or it works like that if you plan to scam the users) or 2nd chance that they got hammered by sharps because they put limit insanely high without any risk management work and with delaying withdrawals and not responding to complaints they try to recuperate some of the losses.
I wouldn't put much trust in Shuffle because i am not ready again to wait 1-2 months for them to pay me and give me exactly 0 INFORMATIONS behind it.
Even if account is multi-accounting or something else they really need to respond and give information. No bookie takes 3 months to reply or check one account, it can be done in 1-2 weeks max if they have work overload.
