Under Rule 4, the odds of the remaining competitors may be adjusted to account for the change, usually resulting in a deduction from the winnings based on the odds of the withdrawn participant. This means that if a bet is placed on a horse that ultimately does not race, the payout for the winning bet may be reduced according to the new odds that reflect the absence of that horse.
Rule 4 Example
For example, if you bet on a horse to win at odds of 5/1, but that horse is scratched before the race, Rule 4 may apply. If the horse’s odds were 2/1, a deduction might be taken from your potential winnings, altering your payout accordingly based on the new circumstances.
