Manufacturers must design, construct, and manufacture punch boards to eliminate any patterns between punch boards or portions of punch boards from which someone could determine the location or approximate location of winning punches.

(1) Manufacturers must randomly distribute and mix winning punches among all other punches in the punch board. To ensure no patterns exist, manufacturers must:

(a) Mix the form or permanent number sheets before cutting; and

(b) Thoroughly mix all strips after the strips have been crimped and before inserting them into the punch boards; and

(c) When filling punch boards, change the process for filling each separate set to prevent any pattern between sets of punch boards; and

(d) Include no more than eight punch boards from one set of boards in any case shipped to Washington.

(2) Manufacturers must make serial numbers on punch boards nonsequential to ensure no pattern exists which would allow someone to track the boards through serial numbers.

(3) Manufacturers must:

(a) Guarantee that all numbers or symbols listed as winners on the flare are present in the board; and

(b) Seal all punch boards to prevent anyone from using any method, including light or markings, to discover the number or symbol on a punch before punching it out of the board; and

(c) Not allow punch boards with taped sides, corners, or edges.

(4) Manufacturers may place stickers on the back of the punch boards naming additional numbers or symbols they guarantee to be in the board. The additional numbers or symbols must not exceed five percent of the total punches in the board, unless the manufacturer receives written permission from us.

(5) Punch boards are exempt from secondary verification code requirements.
