ANSWER: There’s actually a subsection of the Washington Administrative Code (WAC)—the state’s regulatory code—addressing this
very question, under the heading of “bucket raffles.” If all of the tickets are
good for all of the prizes—i.e. purchasers buy tickets that they can choose to put into the drawing for any of the prizes—then the state Gambling Commission considers the activity to be one raffle, and only one license is required.
However, if different tickets are sold for each of the prizes then each of the drawings is considered a separate raffle. You can view the WAC here (look at subsection (6), “bucket raffles”) or obtain more information from the Washington State Gambling Commission via its website (www.wsgc.wa.gov) or by calling 1-360-486-3440.
