Chips/Palace
All non-tribal casinos in Washington are required to close for four hours a day. Some chains have two casinos on the same property with their hours staggered such that at least one of the two casinos is always open.
This is the case for Chips and Palace Casinos in LaCenter and Lakewood. The Chips in Bremerton is a stand-alone and does not offer 24/7 gaming.
Compared to other casinos in the state:
Rules - Average (Hit soft 17, Double After Split, No Surrender)
Penetration - Usually decent on the 6D game. Marginal at best for 2D.
Heat - More sweaty than most casinos
The Chips/Palace games are playable, but it is definitely possible to find better conditions elsewhere.
I have to disagree with mdlbj's comments about Tulalip. In my opinion, Tulalip offers some of the worst games in the state. Penetration is usually horrible, and the largest table max I've ever seen is $500. In fact, for the entire state, the max bet a tribal casino can offer is $500, and the max bet a non-tribal casino can offer is $200.
