The word "casino" is used very loosely in Montana. There are no house banked games not even in Indian casinos so the only games with cards and chips are in the poker rooms. The rest of the "casinos" on this list are gas stations, convenience stores and strip malls with video poker and keno machines. Here's a $1 chip from the Crystal in Billings where Layne Flack and Annie Duke got their start in poker.
