Yes, you all are right

. Right now I know just two (or three) Russian casinos.
Eek, you know, casinos tell us that our financial transactions are 100% protected. CC number cracked even in a year time is a great threat, so I hope 1024 key should be stable enough.
One of the casinos makes 1 hour file. Another makes MD5 signed file exactly as GrandMaster wrote.
About extreme results. We had an author on Russian forums which always said - you should be happy when 15 red come in a row, just imagine how much you can win betting on this streak!
