Card game licensees must conduct card games according to the approved rules of play. We enforce rules of play in the following order:

(1) First priority: Rules explained in Title 230 WAC; and

(2) Second priority: Rules explained by a licensed manufacturer of a patented game that we have approved; and

(3) Third priority: House rules card game licensees have developed and we have approved; and

(4) Fourth priority: Rules explained in the most current version of The New Complete Hoyle, Revised or Hoyle's Modern Encyclopedia of Card Games, or a similar authoritative book on card games which we have approved.
