Hi Rick:

You can rule out any Nevada casinos from the list.

Regulation 12 of the Nevada Gaming Commission and
State Gaming Control states:

12.060, item 2: "A licensee .... (b) shall issue chips and tokens only to patrons of its gaming establishment" and "(d)...state law prohibits the use of the licensee's chips, outside the establishment for any monetary purpose"

It appears we are all in violation of 12.060, item 2(d).
