(A) The object of the quinella is to select in one combination, on a single ticket, the first two horses or separate wagering interests (if there are entries or fields) to finish in a race as officially posted. The order in which the horses finish is immaterial.
(B) The quinella is calculated as an entirely separate pool and, except for the contingencies below, is calculated in the same general manner as a win pool.
(C) If a horse in a race on which there is quinella wagering is excused by the stewards, all monies wagered on combinations which include this horse shall be deducted from the quinella pool and refunded to the purchaser of tickets on the horse unless such horse is part of a field or entry (see paragraph (E) of rule 3769-3-02 of the Administrative Code).
(D) If no ticket is sold combining the horses, or separate wagering interests, that finish first and second, then the net pool shall be calculated as a place pool between those having tickets including the horse (wagering interest) that finished first and those having tickets including the horse (wagering interest) that finished second. If no tickets are sold on one such combination, then the net pool will be distributed as a win pool to those holding tickets on the other combination.
(E) In the event that a race on which there is a quinella wagering should result in a dead heat for second place, the payoffs will be calculated in the same manner as a place pool. In such a race, if there is a dead heat in the win, the net quinella pool shall be calculated and distributed as a win pool to the holders of such tickets as selected both horses adjudged to have finished in said dead heat. If more than two horses are adjudged to have finished first in a dead heat for win, the amounts wagered on all combinations of any two of the horses adjudged to have finished in such dead heat shall be deducted from the net pool to determine the profit which shall be divided into as many equal parts as there are combinations of any two horses. Each part shall be divided by the amount wagered on one such combination to determine the profit per dollar, to which profit the wager shall be added in totaling the payoff.
(F) In a quinella pool, if two horses which are part of a field or entry finish in a dead heat for first then the quinella pool is calculated as a win pool for the holders of those tickets selecting the field or entry and the next separate betting interest as officially posted. If such field or entry horses finish in a dead heat for second, the quinella pool is calculated as a win pool for the holders of tickets who selected the non-field or entry winning horse and the field or entry.
(G) If no ticket was sold that would require distribution of a quinella pool to a winner or winners as defined above, the permit holder shall make a full refund of the quinella pool to those who purchased quinella tickets.
