In December, I have been invited to Red Rock to play with $750 in promotional chips. Here's my question: Say I played roulette and put all $750 on Red (not my plan, but it simplifies my question) and win my bet. I know I receive the winnings in regular chips but what happens to the original $750 in promotional chips at this point? Since they have been wagered, can they now be switched to regular chips or do I have to continue to bet them until I lose them?
