(b) Have a separate numbering system that is randomly distributed when compared to the card number imprinted in the "free" space. Manufacturers must use procedures that mix cards or sheets of cards so that:

(i) No consistent relationship exists between the "card numbers" and separate numbering system within a set or subset; and

(ii) No patterns or consistent relationships exist in the location of a specific card number between subsets from different sets; and

Licensees must sell each complete set or subset of cards before they issue any cards from a different set or subset. Licensees may sell cards from more than one set during a game if care is taken to ensure that no duplicate cards are sold; and

(d) Complete all play during a single session and only use cards that are sold during that session; and

(e) Select and call a new set of numbers for each game or set of games (example: "On the way" games); and

(c) For prizes of two hundred fifty dollars or more:

(i) Have the winner sign the winning card on the back to verify a winner; and

(ii) If using a two-part card, record a neutral player's name and complete address on the back of the original card to verify the winning card was paid; and
