The message is pretty clear.
Quote:
determination of the legality of real money casino play is the Player’s sole responsibility. By placing real wagers, the Player warrants that he/she is legally able to do so within his/her jurisdiction
I suspect this clause was recommended by their legal team so that the CASINO couldnt be charged for aiding and abetting in the US or other territories where players might be in violation of local laws or ordinances.
Now, wheather they are still obligated to pay winnings or not is another story. I dont believe this term in and of itself is saying that they wont pay players, it’s saying they arent responsible for dertiming the legality of play in a geographic area.
