## Horse Racing - Rule 4

If you receive less than expected from a horse racing win, your bet may have been affected by Rule 4. You can check this in your betting history.

#### What is Rule 4?

Rule 4 is a Tattersalls Rule of Racing. It means that when there is a late withdrawal of a horse (it’s listed as a ‘non-runner’), the payout on the other runners in the race will be decreased to compensate. This is because the starting odds no longer reflect each runner’s likelihood to win.

#### How much will the payout decrease by?

The decrease in payout depends on the odds of the non-runner at the time of its withdrawal. Every odds value corresponds to a deduction in pence per pound – the shorter the odds, the larger the deduction (see table below). This deduction is taken from every £1 of your winnings.

#### Example:

• You place a bet of £10 on a horse at odds of 2.25, with a potential payout of £22.50 (winnings of £12.50 plus returned stake).
• A horse with odds of 1.25 is withdrawn, and Rule 4 applies.
• Your horse wins, but your winnings are reduced by 80p per every £1.
• You receive £12.50 (winnings of £2.50 plus returned stake).
