The term "casino" is used very, very loosely in Montana. The vast majority of these are machine only (poker mostly) places that have no table games and, curses, no chips. I vacation there for a few weeks every summer and pick up what I can but pickings are pretty slim, to coin a phrase.

The places that do have table games are restricted, to my understanding, to poker, no house financed games. They have a pot limit of $300 so the turn and river on a $10-$20 hold'em game often plays with open hands as if everybody in the hand were "all in".

Steve Goodrich has a book available that lists chips from Montana with estimated values. Worth having if you are interested in Montana chips.
