I posted that rule from another casino just to show that this kind of play with bonus money is deemed abusive, read that rule entirely it is not about single bet but significant portion of the balance, 1/3 is signigicant portion. Class 1 have this covered in their T&C but not in such explicit form:
"
Class 1 Casino reserves the right to cancel withdrawal requests and withhold winnings made by playing strategies that Class 1 Casino in its sole discretion deems abusive. Furthermore, accounts of players participating in abusive strategies will be terminated upon recognition.".
When I said lazy, I meant to say that person writing T&C didnt think ahead and wrote every single method instead of just putting down generalized version referring to same problem.
I did not force any attitude on You. It is a fact that if You played like that with your money without a bonus, winnings would be yours. If You dont like that fact thats your problem not mine.
Look at the rogue section and read what other casinos have done to get into rogue pit.
It is little outdated but found a link to this forum thread elsewhere and just felt a need to put down my 2. I guess DDoS attack approach failed so its forum posting time now for
OP.
EDIT: Next time when You know something is forbidden in other casinos and there is a possibility that it falls under some generalized rule it might be a good idea to email support before you take some offer and play. It will save you time and money. I do that and dont have problems like you do.
