The slot machines at the Indian casinos in Washington State are "server-based." That means a casino manager can tighten up the machines at will from his office. How many "hand payouts" do you see on the casino floor?! Almost none. Keep your money. Tulalip and the others (Swinomish, Angel of the Winds, etc.) pay next to nothing. Best bet – go to Vegas or Reno. While they have server based slots as well, they are controlled by gaming authorities.
