N.D. Cent. Code § 53-06.2-10
The certificate system allows a licensee to receive money from any person present at a live horse race, simulcast horse race, or simulcast dog race who desires to bet on any entry in that race. A person betting on an entry to win acquires an interest in the total money bet on all entries in the race, in proportion to the amount of money bet by that person, under rules adopted by the commission. The licensee shall receive the bets and for each bet shall issue a certificate to the bettor on which is at least shown the number of the race, the amount bet, and the number or name of the entry selected by the bettor. The commission may adopt rules for place, show, quinella, combination, or other types of betting usually connected with racing.
