(1) Bingo licensees with gross gambling receipts over one hundred fifty thousand dollars in their previous license year must not sell duplicate cards in bingo games. Licensees using cards from multiple manufacturers may result in duplicate cards because the majority of cards in the "1 to 9000 series" are duplicate, regardless of the manufacturer.

(2) Licensees must:

(a) Inform players of limits on prizes if duplicate cards win because Braille cards are in play; and

(b) Not be held responsible for duplicate cards caused by Braille cards in play.
