Kinda looks like this was passed to assuage the fear of washington state citizens that they may get arrested for playing online. Washington state is very anti internet gambling. They passed their anti-internet gambling act in June of 2006, and it appears that this bill just provides a defense to prosecution for “recreational gambling.” They’re primarily going after website gambling promoters.

Gambling officials told me The Seattle Times may be afoul of the law because we print a poker how-to column, “Card Shark,” by gambler Daniel Negreanu
Pretty scary shit…if you promote gambling and live in Washington
