i live in the willamette valley between salem and eugene and as far as i know, each county is allowed to make their own laws on gambling. that being said, RD is right in all the counties i know of. no rake or fee can be taken by the house and the house is not permitted to make odds. i have never heard though, that the house can't overcharge for beer and soda to make up for any "lost" revenue for holding a tourney.
