PURPOSE: This rule sets forth the definitions and calculations of the twin trifecta pool.

1. (1) The double triple is a form of pari-mutuel wagering in which the bettor selects the three
2. (3) horses that will finish first, second and third in each of the two (2) designated races of the double triple, in the exact order of finish as officially posted.
3. (2) Double triple tickets shall be sold in denominations of one dollar ($1) and multiples of it. The two (2) races which comprise the double triple shall be approved by the commission and clearly designated in the program.
4. (3) Each bettor purchasing a double triple ticket shall designate his/her three (3) selections as the first three (3) horses to finish in that order in the first race of the designated two (2) races of the double triple.

5. (4) After wagering closes for the first race of the designated two (2) races of the double triple, all applicable commissions and taxes shall be deducted from the pool in accordance with the laws of the state. The remaining net pool shall then be divided into two (2) separate pools of equal amounts. The following apply:

   1. (A) The first part of the divided pool shall be distributed among the holders of double triple tickets selecting the first three (3) horses, in exact order of finish, on the designated first race of the double triple, in accordance with established pari-mutuel practice. The first part of the divided pool shall consist of one-half (1/2) of the net distributable pool of the total monies wagered on the first race of the double triple on the current day’s program only. Specifically excluded from this shall be any carry-over of any double triple pool from any previous day’s program; and
   2. (B) The second part of the divided pool shall be placed in a separate pool to be distributed among holders of second half double triple tickets selecting the first three (3) horses, in exact order, on the designated second race of the double triple, in accordance with the established pari-mutuel practice.
6. (5) In the first race of the double triple only, if there is a failure to select the first three (3) horses, in exact order of finish, payoffs shall be made on double triple tickets selecting, in the following order of priority, which are the first two (2) horses in exact order, but if there is no ticket outstanding, then the first horse. Failure of any ticket to select the first horse to win, regardless of the selection of the exact order of the second or third horse, or both, shall cause a refund of all double triple tickets issued on that race. Any ticket within the applicable order of priority as previously stated shall be deemed a winning ticket entitling the holder of it to an exchange ticket, in addition to the applicable payoff from the first part of divided pool.
7. (6) After the official declaration of the first three (3) horses to finish in the first race of the double triple, each bettor holding a winning ticket, before the running of the second designated race of the double triple, shall exchange at the designated double triple windows the winning ticket for both the monetary value from the first part of divided pool, as established by the mutuels department of the association, and a double triple exchange ticket which designates the bettor’s selection of the three (3) horses for finish in that order in the second designated race of the double triple. Further money may not be required of the holder of the winning ticket in order to make the exchange. Until the second race of the double triple has been declared official, a person may not disclose the number of winning double triple tickets eligible for exchange in the second double triple race nor shall any person disclose any information regarding those tickets during the exchange process.
8. (7) A double triple exchange ticket for the second race of the double triple may not be issued except upon surrender of the double triple ticket from the first race as described in these rules. Windows, for the purpose of cashing and exchanging of winning double triple tickets, shall be open for the purpose of making exchange as described previously only after the first race of the double triple has been declared official. The windows shall close when wagering closes for the second race of the double triple.
9. (8) If a winning double triple ticket from the first race is not presented for cashing and exchange within the time provided as previously stated, the bettor may still collect the monetary value attached to the ticket but shall forfeit all rights to any distribution resulting from the second race of the double triple.
10. (9) If a dead heat(s) occurs in either the first race or second race of the double triple, six hundred eleven (611) double triple tickets selecting the correct order of finish counting a horse in a dead heat as finishing in any position, dead heated shall be winning tickets, and, contrary to the usual practice, the aggregate winning tickets shall be divided into the net pool and be paid the same pay-off price.
11. (10) If there is no double triple ticket issued accurately selecting the officially declared first three (3) finishers of the second race of the double triple, in the exact order, the second race pool, determined as provided in this rule, shall be held for the next consecutive racing day and combined with the pool of that program’s second race of the double triple. Distribution of this special cumulative pool of the second race of the double triple shall be made only upon the accurate selection, in the exact order, of the first three (3) officially declared finishers of the second race of the double triple.
12. (11) If a horse is scratched in the first race of the double triple, all double triple tickets issued which include the scratched horse shall be refunded. If a horse is scratched in the second race of the double triple and there has been double triple wagering on the scratched horse, public address announcements shall be made and the stewards/judges shall attempt to allow a reasonable time, as determined in their sole and final discretion, for exchange of tickets issued which include the scratched horse. If there has been double triple wagering on the scratched horse and the stewards/judges determine in their sole and final discretion that sufficient time for exchange of tickets on the scratched horse cannot be allowed before the race begins, then the entire second part of the divided pool resulting from that current day’s program only shall be distributed among all holders of second half double triple tickets, in accordance with established pari-mutuel practice, and any carry-over of any double triple pool from any previous day’s program may not be distributed on that racing day and shall be carried over to the next consecutive racing day.
13. (12) If for any reason the field for either the first race or the second race of the double triple is reduced to less than seven (7) interests before wagering is opened for the first race of the double triple, then double triple wagering may not be conducted on that day. If wagering has opened for the double triple and the field for either the first race or the second race of the double triple is reduced to less than seven (7) interests before the first race of the double triple has been run, the stewards shall determine, in their sole and final discretion, whether double triple wagering will be refunded and not conducted on that day. If after the first race of the double triple has been run, the field in the second race of the double triple is reduced to less than seven (7) interests, the stewards shall determine, in their sole and final discretion, whether the race will be run as the second race of the double triple or, alternatively, whether double triple wagering will be canceled, in which event the entire second part of the divided pool resulting from that current day’s program only shall be distributed among all holders of second half double triple tickets, in accordance with established parimutuel practice, and any carry-over of any double triple pool from any previous day’s program may not be distributed on that racing day and shall be carried over to the next consecutive racing day.
14. (13) If for any reason, the second race of the double triple is not declared official, the winning ticket holders who have cashed their tickets of the first race of the double triple and have received exchange tickets, shall be 12 CSR 50-80

entitled to be paid the remaining amount of the current program’s divided pool.

1. (14) Sales of double triple tickets other than from pari-mutuel machines shall be deemed illegal and prohibited.
2. (15) The double triple pool shall be held entirely separate from all other pools and may not be part of a daily double, exacta, triple, pick six or other wagering pool.
3. (16) If the accumulated carry-over pool of the double triple has not been distributed before the closing day of the meeting in which the pool was generated, the net amount of the final pool so remaining on the closing day shall be distributed among holders of those tickets on the second race of the double triple as selected, in the following order of priority which is the first two horses in the exact order, but if there is no ticket outstanding, then the first horse to win, regardless of the selection of the exact order of the second or third horse, or both, or if there is a cancellation of the final day’s program, the accumulated pool shall be evenly distributed to all holders of first half winning tickets and all holders of second half double triple exchange tickets.
4. (17) Coupled entries and fields are prohibited in double triple races as they are in triple races.

5. (18) The acceptance of a double triple ticket by taking an issued ticket away from the window of the terminal from which it was issued shall constitute an acknowledgment by the bettor of the correctness of the ticket. Each purchaser of a double triple ticket shall agree to be bound by the terms and provisions of this and all other applicable commission rules and by the laws of the state pertaining to parimutuel wagering. This rule shall be prominently displayed in the betting area of each association conducting a double triple program—the association, totalisator company and the state may not be liable to any person for a double triple ticket which is not—

   1. (A) Considered a winning ticket in accordance with the provisions of this rule; and
   2. (B) Delivered for any reason including, but not limited to, mechanical malfunction, electrical failure, machine locking or other cause.
