Did not win. He just broke the site and stole from us over 0.5 BTC from the hot wallet. In the cold wallet he had no access. I do not understand why he accused us of scam when we were robbed by him. We paid all withdrawals every time. There were some delays just because cheatedplayer steal the money from hot wallet. He did not steal the users money. Users has not be affected by this.
Really unfortunate to hear about the loss but you should have taken care of the system as there will be hackers trying to find the exploits and they won, in the future you should make sure that nothing like this happens, even sites like prime dice got hacked in the past but those did not affect them financially and they upgraded they system and never had an incident ever after and hope the same with your site.
