Deposits have already been shut off for that reason.
If you're serious about starting a dice site, ditch the current and start from the ground up. Nobody should trust any site running that code.
Make sure to keep most BTC in cold storage too, post the wallet address and sign it so people know you have enough BTC to pay out.
Honestly though, this looks like a scam site to me. Random domain (well not completely random) and running script known to have exploits. Not saying it is, but you get what I'm saying? It's easy for someone to run with BTC and blame it on poor coding.
