What’s Rule 4?

I’ve noticed a few betting websites mention that bets will follow Rule 4. But what on earth is it? Not every bookie website highlights this Rule 4 notice. I thought I’d investigate and have put my finding below.

Origins of Rule 4 Why are Rule 4 deductions made?

Deductions are made from winnings when a horse (or multiple horses) is withdrawn from a race. This is because it becomes easier for the other runners to win – each horse in the race will have one less other horse to beat. As a result, an amount of money is deducted from winnings to balance the effect of the withdrawn horse(s).

If bookmakers did not make Rule 4 deductions from winnings then in some cases customers would be able to back all the horses in one race and make money whichever horse won! Which would be great for us but not for the bookmakers. The rule, therefore, is in place to protect the income of the bookmakers – poor dears!

Let’s look at an example to make things a little bit clearer. For simplicity’s sake, let’s say there there are only three horses in a race. Big Bobby is the 1.33 (decimal odds) favourite, Lucky Meg is 4 and the third horse, Sunny Days, is 13.

Before this big race Big Bobby is withdrawn and there are no deductions made to the prices of horse Lucky Meg and Sunny Days. In our example if you placed £10 on Lucky Meg and £10 and Sunny Days you would win more than the £20 staked whichever horse won. If Lucky Meg won you would win £40 and if Sunny Days won you would win £130.

Therefore Rule 4 deductions are made to take into account the additional advantage a customer has when a horse is withdrawn from a race.

The Rule 4 deduction are in place to make betting a little more transparent and fairer for all parties involved. How the deductions are worked out are very complicated but they are set in stone. You won’t have to work out the deductions, thankfully, but just be aware that they exist and if you’re winnings don’t look quite right after a horse race, consider Rule 4 as a possible explanation.

Rule 4

Do bookies and exchanges have the same deduction factors/rules for Rule 4?

I bet on a winning horse just there, in a race where one of the other horses was withdrawn at the stalls. I think I have just been shafted out of profit as the exchange appears to have applied a larger deduction than the bookie? Is that normal?

TIA to anyone who can help

Tony I lost about £12 recently on a bet where the horse won with coral, the rule 4 meant a 25p deduction but betfair deducted a percentage. So my liability wasnt reduced as much as my returns from coral. Luckily it was on the 3/1 offer where you get the £10 free bet so that meant I didnt lose as much. But yeah it seems the bookies deduct pence in the pound whereas betfair use %. It could also work in your favour if the horse didnt win.

Rule 4 deductions vary… You’ll need to check the terms for the relevant bookmaker and exchange.

It was a free bet that I was using up. Still got over 80% out of it, but frustrating as I had found good back/lay odds and was expecting nearer 100% but for the non-runner and then my (longshot!) nag winning! Nevermind 🙂
