Just completed a quick review of the Washington section. They do not list the 25 or so non-Indian mini-casinos which also offer house backed table games. Also, their information regarding "electronic games" is completely in error. The State does not allow slot machine which take money. There are hundreds of electronic slots which take bar coded slips which are purchased seperately. The nice thing about these machines is that when you leave a machine, you get a printed slip which is directly playable in another machine. So, I guess I would say it is a good basic reference, but don't bet a lot on the accuracy of all the information.
