R 431.2090 Trifecta.

Rule 2090. (1) The trifecta is a contract by the purchaser of a ticket to select the 3 horses that will finish first, second, and third in the race. The trifecta must be calculated as an entirely separate pool. (2) With respect to a trifecta pool, the amount wagered on the winning combination, such being the horse finishing first, the horse finishing second, and the horse finishing third, in exact order, is deducted from the net pool to determine the profit. The profit is divided by the amount wagered on the winning combination, such quotient being the profit per dollar wagered on the winning trifecta combination. Payoff includes the amount wagered and profit thereon. In addition, the following provisions apply to trifecta pools: (a) If no ticket is sold designating, in order, the first 3 horses, the net pool shall be distributed equally among holders of tickets designating the first 2 horses in order. (b) If no ticket is sold designating, in order, the first 2 horses, the net pool shall be distributed equally among holders of tickets designating the first horse to win. (c) If no ticket is sold designating the first horse to win, the net pool shall be distributed equally among holders of tickets designating the second and third horses in order. (d) If less than 3 horses finish, the payoff shall be made on tickets selecting the actual finishing horses in order, ignoring the balance of the selection. (e) If there is a dead heat, all trifecta tickets selecting the correct order of finish, counting a horse in a dead heat as finishing in either position involved in the dead heat, shall be winning tickets. The payoff must be calculated as a place pool. (f) If no ticket is sold that would require distribution of a trifecta pool, the association shall make a complete and full refund of the trifecta pool. (3) If a horse is scratched or declared a non-starter, all trifecta tickets previously issued designating such horse shall be refunded and deducted from the gross pool.
