(a) If no daily double ticket is sold designating the winner of the first race, or the first race is cancelled or declared “no race”, the daily double shall be declared off and the gross pool refunded.

(b) If no daily double ticket is sold combining the winners of the first and second races, or the second race is cancelled or declared “no race”, the net pool shall be distributed to holders of tickets designating the winner of the first race, as in a win pool and the daily double shall terminate.

(c) In the event of a dead heat in either or both daily double races, holders of daily double tickets combining winners in both such races shall be entitled to a distribution calculated as in a win pool dead heat.

(d) If a horse is scratched from the first or second daily double races before the running of the first daily double race, all daily double tickets selecting the horse scratched shall be refunded and the money deducted from the gross pool.

(e) Should any horse be scratched or be declared a nonstarter in the second half of the daily double after the first half of the daily double has been raced, all tickets combining the scratched horse with the winner of the first half shall become consolation tickets and shall be paid at a price per dollar bet determined as follows: the net daily double pool (the gross daily double pool less tax) shall be divided by the total purchase price of all daily double tickets designating the winner of the first half of the daily double and the quotient obtained shall constitute the price to be paid. The total amount payable on consolation tickets shall be deducted from the net daily double pool.
