I have to share my experience with Dolfwin casino.
I played at dolfwin casino making some bonus buys and i won 5215eur. Then i waited 8 days my withdraw just to see that my account was empty of the money. My withdraw was cancelled and played back to the casinoslots.
I did not cancelled it and played any euros. I have told this to the casino but casino said "you cancelled withdraw and played money". I have requested they many times to check my ip addresses from played sessions but they have answered nothing to this after long period for waiting. They have closed my account too.
I know that this thing is made by casino (Its not a single hacker, because i had money on 8 different sites with same login details and this was only one where money was gone) because playing was started exactly same bonus buys what i did, Then after those buys balance was increased from 5215 to about 5400 and then there is about 100 spins in three minutes with 100e single bet.
HUGE warning to other players, dont ever deposit any money to this site!
