(1) The twin trifecta requires selection of the first three finishers, in their exact order, in each of two designated races. Each winning ticket for the first twin trifecta race must be exchanged for a free ticket on the second twin trifecta race in order to remain eligible for the second-half twin trifecta pool. Winning first-half wagers will receive both an exchange and a monetary payoff. Both of the designated twin trifecta races will be included in only one twin trifecta pool.

(2) Twin trifecta wagering may be conducted by Class A and B licensees at the discretion of the commission upon written application by an association.

(3) After wagering closes for the first-half of the twin trifecta and commissions have been deducted from the pool, the net pool will then be divided into two separate pools: The first-half twin trifecta pool and the second-half twin trifecta pool. The percentage allocated to each pool must be approved by the commission.

(4) In the first twin trifecta race only, winning wagers will be determined using the following precedence, based upon the official order of finish for the first twin trifecta race:

(a) As a single price pool to those whose combination finished in the correct sequence as the first three betting interest; but if there are no such wagers, then

(b) As a single price pool to those whose combination included, in correct sequence, the first two betting interests; but if there are no such wagers, then

(c) As a single price pool to those whose combination correctly selected the first-place betting interest only; but if there are no such wagers, then

(d) The entire twin trifecta pool for that day will be refunded on twin trifecta wagers for that race and the second-half will be canceled.

(5) If no first-half twin trifecta ticket selects the first three finishers of that race in exact order, winning ticket holders will not receive any exchange tickets for the second-half twin trifecta pool. In such case, the second-half twin trifecta pool will be retained and added to any existing twin trifecta carry-over pool.

(6) Winning tickets from the first-half of the twin trifecta will be exchanged for tickets selecting the first three finishers of the second-half of the twin trifecta. The second-half twin trifecta pool will be distributed to winning wagers in the following precedence, based upon the official order of finish for the second twin trifecta race:

(a) As a single price pool, including any existing carry-over moneys, to those whose combination finished in correct sequence as the first three betting interest; but if there are no such tickets, then

(b) The entire second-half twin trifecta pool for that race will be added to any existing carry-over moneys and retained for the corresponding second-half twin trifecta pool of the next consecutive race card.

(7) Subject to subsection (18)(e) of this section of the twin trifecta rules, if a winning first-half twin trifecta ticket is not presented for cashing and exchange prior to the second-half twin trifecta race, the ticket holder may still collect the monetary value associated with the first-half twin trifecta pool but forfeits all rights to any distribution of the second-half twin trifecta pool.

(8) Twin trifecta wagering is prohibited on any race in which there is a mutuel field, except with written permission of the executive secretary.

(9) Should a betting interest in the first-half of the twin trifecta be scratched, those twin trifecta wagers including the scratched betting interest will be refunded.

(10) Should a betting interest in the second-half of the twin trifecta be scratched, an announcement concerning the scratch will be made and a reasonable amount of time will be provided for exchange of tickets that include the scratched betting interest.

(11) If there is a dead heat or multiple dead heats in either the first- or second-half of the twin trifecta, all twin trifecta wagers selecting the correct order of finish, counting a betting interest involved in a dead heat as finishing in any dead-heated position, will be a winner. In the case of dead heat occurring in:

(a) The first-half of the twin trifecta, the payoff will be calculated as a profit split

(b) The second-half of the twin trifecta, the payoff will be calculated as a single price pool.

(12) If either of the twin trifecta races are canceled prior to the first twin trifecta race, or the first twin trifecta race is declared "no contest," the entire twin trifecta pool for that day will be refunded on twin trifecta wagers for that race and the second-half will be canceled.

(13) If the second-half twin trifecta race is canceled or declared "no contest," all exchange tickets and outstanding first-half winning twin trifecta tickets will be entitled to the net twin trifecta pool for that race as a single price pool, but not the twin trifecta carry-over. If there are no such tickets, the net twin trifecta pool will be distributed as described in subsection (4) of this section of the twin trifecta rules.

(14) If, due to a late scratch, the number of betting interests in the second-half of the twin trifecta is reduced to fewer than 3, all exchange tickets and outstanding first-half winning tickets will be entitled to the second-half twin pool for that race as a single price pool, but not the twin trifecta carry-over.

(15) If it be determined by the stewards that a horse has been prevented from racing because of the failure of the stall door of the starting gate to open (nonstarter) in the second-half of the twin trifecta only, there will be no refund or consolation payoff. The official order of finish as posted will be used to determine payoffs. This will not affect other pools for this race.

(16) A written request for permission to distribute the twin trifecta carry-over on a specific race card may be submitted to the commission. The request must contain justification for the distribution, an explanation of the benefit to be derived, and the intended date of race card for the distribution.

(17) Contrary to subsection (5) of this section of the twin trifecta rules, during a race card designated to distribute the twin trifecta carry-over, exchange tickets will be issued for those combinations selecting the greatest number of betting interests in their correct order of finish for the first-half of the twin trifecta. If there are no wagers correctly selecting the first-, second-, and third-place finishers, in their exact order, then exchange tickets will be issued for combinations as described in subsection (4) of this section of the twin trifecta rules.

(18) Should the twin trifecta carry-over be designated for distribution on a specified date, the following precedence will be followed in determining winning tickets for the second-half of the twin trifecta after completion of the first-half of the twin trifecta:

(a) As a single price pool to those whose combination finished in correct sequence as the first three betting interests; but if there are no such wagers, then

(b) As a single price pool to those whose combination included, in correct sequence, the first two betting interests; but if there are no such wagers, then

(c) As a single price pool to those whose combination correctly selected the first-place betting interest only; but if there are no such wagers, then

(d) As a single price pool to holders of valid exchange tickets.

(e) As a single price pool to holders of outstanding first-half winning tickets.

(19) The twin trifecta carry-over will be designated for distribution on a specified date and race card only under the following circumstances:

(a) Upon written approval from the commission as provided in subsection (16) of this section of the twin trifecta rules.

(b) On the closing race card of the meet or split meet.

(20) If, for any reason, the twin trifecta carry-over must be held over to the corresponding twin trifecta pool of the association's subsequent meet, the carry-over will be deposited in an interest-bearing account approved by the commission. The twin trifecta carry-over plus accrued interest will then be added to the second-half twin trifecta pool of the association's following meet.

(21) If racing is canceled prior to the first-half of the twin trifecta on the closing race card of the meet or split meet, the carry-over will be held over in accordance with subsection (19) of this section of the twin trifecta rules.

(22) If racing is canceled after the running of the first-half but before the running of the second-half on the closing race card of the meet or split meet, the carry-over pool will be paid as a single price to holders of exchange tickets or outstanding winning tickets from the first-half.

(23) Providing information to any person regarding covered combinations, amounts wagered on specific combinations, number of tickets sold, or number of valid exchange tickets is prohibited. This will not prohibit necessary communications between parimutuel system and parimutuel department employees for processing of pool data.

(24) The acceptance of a twin trifecta ticket by taking an issued ticket away from the window of the terminal from which it was issued will constitute an acknowledgment by the bettor that the ticket is correct. Exchange tickets may not be canceled and/or reissued except as provided by these rules. The association, parimutuel company, and state will not be liable to any person for a twin trifecta ticket which is not:

(a) A winning ticket in accordance with the provisions of this rule; or

(b) Delivered for any reason, including but not limited to mechanical malfunction, electrical failure, machine locking, phone line failure, or other cause.

(25) Twin trifecta tickets will be sold and exchanged only by the association through parimutuel machines.

(26) The twin trifecta carry-over may be capped at a designated level approved or set by the commission so that if, at the close of any race card, the amount in the twin trifecta carry-over equals or exceeds the designated cap, the twin trifecta carry-over will be frozen until it is won or distributed under other provisions of this rule. After the twin trifecta carry-over is frozen, 100 percent of the net twin trifecta pool for each individual race will be distributed to winners of the first-half of the twin trifecta pool.
