EDIT: This is what I got in the mail, word for word.
"Hello,
We're writing you because you're our investor on https://www.crypto-games.net website.
One user on bitcointalk forum is claiming that he found some serious bugs on our website.
For security precautions we almost emptied our hot wallets and put coins on cold one.
Let us say that our code is still very secure and we have hack attempts every day, but nobody hacked or stealed anything.
If you still want to divest over 1 bitcoin (or similar), write us and we'll send you coins manually.
Best regards,
Crypto-Games"
No, they are not hacked. You should read carefully, someone claimed that he has notice an exploit to get +EV and that is risky for investor. Here is the details for that https://bitcointalksearch.org/topic/crypto-gamesnet-30-house-edge-bugs-and-vulnerabilities-screw-the-investors-1106133. It is all fixed now and you dont have to worry about this
All good now.
