What is a Lucky 15 bet and how does it work?

A Lucky 15 horse racing bet is comprised of 15 bets. It can appeal if you have four horse racing fancies that you’d like to back. Typically, they might all be favourites to win their respective races, or alternatively they may all be ridden by the same jockey.

While some people prefer backing their selections as singles, and others are drawn to an accumulator, a Lucky 15 can be seen as a halfway house, offering the prospect of a big win while ensuring one horse losing doesn’t mean you lose your entire stake.

Here we’ll explain more about this Lucky 15 bet, so you can make an informed decision about whether to place similar Lucky 15 bets yourself.

How does a Lucky 15 work?

A Lucky 15 is appropriately named, as it is made up of 15 bets in total – 4 singles, 6 doubles, 4 trebles and a fourfold. Your stake is multiplied by 15, so a £1 bet would cost you £15 overall. That’s £1 on each of the 15 bets that make up a Lucky 15.

Bet typeSelections in betNumber of bets
SinglesHorse 1; horse 2; horse 3; horse 44
DoublesHorses 1+2; 1+3; 1+4; 2+3; 2+4; 3+46
TreblesHorses 1,2+3; 1,2+4; 1,3+4; 2,3+44
FourfoldHorses 1,2,3+41

How to work out Lucky 15 winnings

Working out your potentially winnings from a Lucky 15 can be a laborious process, given it involves 15 separate bets. You’re therefore best off using our Grand National accumulator calculator to calculate what could be won from the doubles, trebles and fourfold included in your Lucky Fifteen bet. Alternatively, most bookmakers will display the amount you would win once you’ve added your selections to your betslip.

If you’d still prefer to work out what your Lucky 15 would pay out, convert your odds from fractional to decimal format, and follow the steps below.

Single bets: decimal odds x stake = return (including stake)
Doubles: horse 1 odds x horse 2 odds = return (including stake)
Trebles: horse 1 odds x horse 2 odds x horse 3 odds = return (including stake)
Fourfold: horse 1 odds x horse 2 odds x horse 3 odds x horse 4 odds = return (including stake)

Is a Lucky 15 bet Worth it?

Whether or not a Lucky 15 is worth it depends on the individual placing the bet, as we all have different levels of aversion to risk, and reasons why we bet. The table below summarises the main pros and cons of placing Lucky 15 bets.

Pros of placing a Lucky 15Cons of placing a Lucky 15
Potential to win large amounts from a small stakeHigher risk than placing bets on individual selections
Unlike an acca, the bet remains alive until your final horse has runOutlay is likely to be bigger than if placing a normal accumulator
Far more chance of winning something than with an accumulator2 or even 3 of your 4 horses often need to win to give an overall profit
Provides a halfway house between singles and accumulatorsAll 15 bets must have the same stake

How Does a Lucky 15 Each Way Work?

An each way bet gives you the chance to win your bet if your horse either wins a race OR finishes in the top few places. This principle can be extended to Lucky 15s when you’re placing an each way Lucky 15 bet. Instead of betting on a single horse to win or place in a race, you’re hoping for a number of horses all to win or be placed. The table below explains how your bet would fare in each different scenario.

All 4 horses winWinnerWinner

*The exact number of places will vary depending on the bookmaker you bet with and the race you bet on. For the Grand National though, this will be at least 4 places, and often 5 or more.
