according to an article about the new limits at Caesars in "Slots Today" (Dec 11/Vol. 32 No. 50)

Roulette players who were limited to $500 "any way" wagers will enjoy new wagering limits of $3,000 "any way".

On my way out of work today I asked a floor manager and a dealer what the any way maximum was at the Palms. The dealer said $200. The floor said "I'm new here and I'm not sure"...I said is it $200? He said that sounds right. Then as I was walking away he said maybe it's $500. If you are really interested, I can ask again on Friday when I go back to work.
