Good question. When I was last there only a few off the strip and small downtown ones did. That was in July at this point I’d guess only the very small and local spots only still use coins.

Why would you want 400 quaters that weigh a ton??

I live and work in Vegas and i am sad to say that 98% of all Vegas casinos now use the paper ticket to pay out, it is just more efficient to use the paper then coins because it is less heavy and less dirty as well.

All of the downtown casinos still have some coin machines.
