I do not think that the coin is lost, the casino have access to the coin because the address is there own, it was copied from the casino site. Even if I copied the right address but made a mistake and send the wrong coin and the transaction was confirmed. It has already gone to the casino account. I do not have the private keys to the address on the casino, the casino provides the address for me, so anytime I made deposit to the address they add it to my account. Casino normally makes rules because they know gamblers will always make a mistake as we are not perfect. Moreover,as the fault is from the sender the casino has the right to hold back his money or to return back his money because it is in there rules.
