(1) No tri-superfecta wagering shall be conducted without permission of the board. The races in which the tri-superfecta parimutuel wagering will be permitted shall only be those designated by the board and a separate pool shall be established.

(2) The tri-superfecta is a form of parimutuel wagering in which the bettor selects the three horses which will finish first, second, and third in the first of the two designated races in the exact order of finish as officially posted and must select the four horses which will finish first, second, third, and fourth in the second of two designated races, in the exact order of finish as officially posted.

(3) Each bettor purchasing tri-superfecta tickets shall designate his three selections as the first three horses to finish in that order in the first race of the two designated races.

(4) After the wagering closes for the first half of the tri-superfecta the remaining pool will then be divided into two separate pools terms "first part of the divided pool" and "second part of the divided pool." The first part of the divided pool will be a percentage of the remaining pool determined by the association with approval of the board. The second part of the divided pool will be the amount remaining after the first part of the divided pool has been deducted.

(5) The monies in the first part of the divided pool will be distributed to the holders of the tri-superfecta tickets selecting the first three horses in order, on the first designated tri-superfecta race, in accordance with established parimutuel practice.

(6) The second part of the divided pool will be placed in a separate pool to be distributed to the holders of "second half" tri-superfecta tickets selecting the first four horses in order as officially posted on the second designated tri-superfecta race, in accordance with established parimutuel practice.

(7) In the first half of the tri-superfecta only, if there is a failure to select the first three horses in exact order of finish as officially posted, the first part of the divided pool shall be distributed and exchanges made on tri-superfecta tickets selected in the following order of priority:

(a) first, second, and fourth;

(b) first, third, and fourth;

(c) second, third, and fourth;

(d) first, second, and fifth;

(e) first, third, and fifth;

(f) first, fourth, and fifth;

(g) and sequentially thereafter.

(8) After the official declaration of the first three horses to finish in the first race of the tri-superfecta, each bettor having first half winning tickets as determined by (7) shall exchange such winning tickets at the windows for both the monetary value established by the mutuel department and the tri-superfecta exchange ticket and at such time, shall select the four horses to finish in the second race of the tri-superfecta in the exact order as officially posted. No further money shall be required of the holders of the winning first half tickets in order to make the exchange.

(9) No tri-superfecta exchange ticket for the second race shall be issued except upon surrender of the tri-superfecta ticket from the first race as described in these rules. All windows for the purpose of cashing and exchanging winning tri-superfecta tickets shall be open for the purpose of making the exchange as described only after the first race has been declared official and all windows shall close at the start of the second race of the tri-superfecta.

(10) If a winning tri-superfecta ticket from the first race is not presented for cashing and exchange within the time provided, the bettor may still collect the monetary value attached to the ticket but forfeits all rights to any distribution of the second race tri-superfecta pool.

(11) If a horse is scratched in the first race of the tri-superfecta, all tri-superfecta tickets on the scratched horse will be refunded. If a horse is scratched in the second half of the tri-superfecta, public announcements will be made and reasonable time will be given for the exchange of tickets on the scratched horses. If, due to a late scratch in the first half of the tri-superfecta, the field becomes less than seven, all money into the tri-superfecta on that program will be refunded and the tri-superfecta for that program shall be declared "off." If, due to a late scratch in the second half of the tri-superfecta the field becomes less than seven, those persons with valid exchange tickets will be entitled to the remaining amount of that program's divided pool which shall be divided into equal amounts relative to the number of valid exchange tickets. The jackpot pool will remain undistributed and be carried over to the next tri-superfecta program.

(12) In the event of a dead heat or dead heats in either the first or second race of the tri-superfecta, all tri-superfecta 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. In the case of the dead heat occurring on the first half, the payoff shall be calculated as a place pool. In the case of the dead heat occurring in the second half, contrary to the usual parimutuel practice, the aggregate number of winning tickets shall be divided into the net pool and paid the same payoff price.

(13) In the event that racing is canceled for any program prior to the running of the second half of the tri-superfecta, or if less than four horses finish in the second race of the tri-superfecta, or the racing officials declare the second half "no race," then the second part of the program's divided pool will be evenly distributed to all tri-superfecta exchange tickets and the carry over jackpot pool will remain undistributed and be carried over to the next tri-superfecta program.

(14) Not more than one race shall elapse between the race designated as the first half of the tri-superfecta and the race designated as the second half of the tri-superfecta.

(15) Coupled entries and mutual fields are prohibited in tri-superfecta races.

(16) Fields for tri-superfecta races shall contain no less than seven horses.

(17) Tri-superfecta wagers shall be made in denominations of two dollars only.

(18) On the closing day of the meeting, the current jackpot pool, including the second part of the divided pool from the closing program, if any, shall be distributed in the following manner to tickets on the second designated tri-superfecta race in that program:

(a) divided equally among those tickets correctly designating the first four finishers in exact order as officially posted;

(b) if no ticket is issued as above described, then equally divided among tickets correctly designating the first three finishers in exact order as officially posted (win-place-show-all);

(c) if no ticket is issued as above described, then equally divided among tickets correctly designating the first two finishers in exact order as officially posted (win-place-all-all);

(d) if no ticket is issued as described, then equally divided among tickets correctly designated the winner to win as officially posted (win-all-all-all);

(e) if no ticket is issued as above described, then equally divided among all second half tri-superfecta tickets.
