Roospin.com is a scam. I recently had a win of $19k roughly and tried to withdraw the winnings but was rejected after I was told I should receive the funds within 10-20 min.
When I spoke to Santana one of the staff via chat, they said "there game provider had pickup up suspicious betting behaviour and there policy states they won’t payout the winnings I asked to see the message they received from game provider but they wouldn’t show me, I asked what did they mean by suspicious behaviour but no explanation was given, I asked to speak to a manager I was ignored I asked for contact details to ring them instead no contact details were provided. My review is that this site is a scam save your money don’t bother playing with this site
