For many horse racing punters, the Lucky 15 is one of the most popular bets on a Saturday afternoon and during the major weekday festivals. It is a staple of British betting culture – particularly during the Cheltenham Festival, Royal Ascot and the big handicap days when four-horse combination bets come into their own.
But how exactly does a Lucky 15 work? How do you calculate the returns, and when is it the right bet to place? This guide covers everything you need to know – including how each-way Lucky 15s work, what happens with a non-runner, and the bookmaker bonuses that make the Lucky 15 so attractive.
For today’s Lucky 15 selections, see our Lucky 15 tips page.
What is a Lucky 15?
A Lucky 15 consists of 15 bets made up of four selections. The name is straightforward – 15 refers to the number of individual bets within the wager, and Lucky refers to the bookmaker’s bonuses that are available when one or all four horses win.
The 15 bets break down as follows:
- 4 singles – one bet on each of the four selections individually
- 6 doubles – every possible combination of two selections from four
- 4 trebles – every possible combination of three selections from four
- 1 four-fold accumulator – all four selections combined
The more horses that win, the more of the 15 individual bets win and the bigger the return. But the crucial difference between a Lucky 15 and a similar bet – the Yankee – is that a Lucky 15 includes the four singles. This means just one winner guarantees a return.
How Much Does a Lucky 15 Cost?
The stake is multiplied by 15. A £1 Lucky 15 costs £15. A 50p Lucky 15 costs £7.50.
| Unit stake | Total cost (win only) | Total cost (each-way) |
|---|---|---|
| 25p | £3.75 | £7.50 |
| 50p | £7.50 | £15.00 |
| £1 | £15.00 | £30.00 |
| £2 | £30.00 | £60.00 |
An each-way Lucky 15 doubles the number of bets to 30 – the 15 win bets plus 15 place bets – so the total cost doubles. A £1 each-way Lucky 15 costs £30.
Lucky 15 Bets Breakdown
Here is exactly what the 15 bets consist of using four selections – Horse A, Horse B, Horse C and Horse D:
4 Singles: A, B, C, D
6 Doubles: AB, AC, AD, BC, BD, CD
4 Trebles: ABC, ABD, ACD, BCD
1 Four-fold: ABCD
Every possible combination of your four selections is covered. If only one horse wins, you collect on that single. If two win, the two singles and one double pay out. Three winners sees three singles, three doubles and one treble win. Four winners and all 15 bets are winners.
Lucky 15 vs Yankee – What is the Difference?
A Yankee uses the same four selections but contains only 11 bets – the 6 doubles, 4 trebles and 1 four-fold. It does not include the singles.
The practical difference is significant. With a Yankee, you need at least two winners to get any return at all. With a Lucky 15, one winner is enough. The trade-off is cost – a Lucky 15 costs 15 units versus a Yankee’s 11 units for the same selections and unit stake.
| Bet type | Selections | Total bets | Minimum winners for a return |
|---|---|---|---|
| Yankee | 4 | 11 | 2 |
| Lucky 15 | 4 | 15 | 1 |
| Lucky 31 | 5 | 31 | 1 |
| Lucky 63 | 6 | 63 | 1 |
There is nothing worse than having a 10/1 winner in a bet but all three other horses losing and getting nothing back. The Lucky 15 solves that problem – at 50p stakes, a single 10/1 winner with double odds applied (see below) returns £5.50 rather than nothing.
What Are Lucky 15 Bonuses?
The “Lucky” part of the name refers to the bookmaker bonuses that most major UK bookmakers apply to Lucky 15 bets. These bonuses apply in two situations:
One winner bonus: If only one of your four horses wins, most bookmakers pay double the odds on that single selection. So a 6/4 winner at normal odds returns £1.25 on a 50p stake. At double odds, you receive £2.00. A 5/1 winner at double odds returns £5.50 rather than the normal £3.00. Some bookmakers on the high street will go further – treble or even quadruple the odds for a single winner.
Four winners bonus: If all four horses win, most bookmakers add a percentage bonus to the total winnings. A 10% bonus on four winning selections at 6/4 each with a 50p stake produces approximately £82 rather than £74.
Bonuses vary between bookmakers – always check the specific terms before placing. Betfred’s Lucky 15 bonus is one of the most competitive on the market. Their standard offer pays treble the odds for one winner and a 10% bonus for all four winning. This is why Betfred is consistently the go-to bookmaker for Lucky 15 bets.
How Does an Each-Way Lucky 15 Work?
An each-way Lucky 15 follows the same principles as any each-way bet – half your stake goes on the win, and half goes on the place. The place part is paid at a fraction of the win odds (typically 1/4 or 1/5) if the horse finishes in the places.
With an each-way Lucky 15 you are essentially placing two separate Lucky 15s – one win and one place – making 30 bets in total. The stake is therefore multiplied by 30.
If two of your horses are placed but neither wins, the place parts of those two singles and potentially a place double would win. The more horses that win outright, the more of the 30 bets pay at full win odds.
An each-way Lucky 15 is generally best used when your selections include horses at 8/1 or bigger. At these prices, the place return alone represents meaningful value, and the each-way insurance against horses running well without winning justifies the doubled stake. For shorter-priced selections, a win-only Lucky 15 is typically better value.
Lucky 15 Non-Runner – What Happens?
If one of your Lucky 15 selections is a non-runner or is declared void, the bet continues without that horse. The non-runner single stake is refunded and all multiple bets that included the non-runner are reduced accordingly.
Using selections A, B, C and D – if D is a non-runner:
- The D single stake is refunded
- The ABCD four-fold becomes a treble of ABC
- Any treble including D becomes a double
- Any double including D becomes a single
- The remaining bets on A, B and C continue as normal
So a Lucky 15 with one non-runner effectively becomes an 11-bet combination (a Yankee equivalent) on the remaining three selections, plus the three singles. You still have a live bet – just on three horses rather than four.
Lucky 15 Returns Examples
Example 1 – One winner at 5/1 (double odds applied, 50p stakes):
Normal single return: £3.00 (£2.50 profit + 50p stake) With double odds bonus: £5.50 (£5.00 profit + 50p stake)
Example 2 – Two winners at 2/1 and 3/1 (50p stakes):
Two singles win: 2/1 = £1.50 return, 3/1 = £2.00 return One double wins: 2/1 x 3/1 combined = 8/1 = £4.50 return Total return: approximately £8.00
Example 3 – Four winners at 6/4 each (50p stakes, 10% bonus applied):
All 15 bets win. Total return approximately £82.
When to Use a Lucky 15
The Lucky 15 is at its best in specific situations. It is not always the right bet for every racing day.
Good situations for a Lucky 15:
Racing days with four strong meetings where you have a genuine view on selections across different races. Saturday afternoons during the Flat season or big National Hunt days at Cheltenham, Sandown or Kempton are ideal. Quality fields with recognisable, well-handicapped horses make selection more achievable.
The Lucky 15 also works well in higher-standard graded races where the fields are smaller and more manageable to assess. Picking four winners from four Grade 1 or Grade 2 contests is difficult but more realistic than taking on four large-field handicaps.
When a Lucky 15 may not be the best option:
During big handicap festivals – particularly the Cheltenham Festival – there are races with fields of 20 or more where picking winners is notoriously difficult. In those situations, placing individual each-way singles on well-priced horses at generous odds may offer a greater return than spreading the stake across 15 permutations. A 10/1 winner in a single each-way bet at £5 stakes returns £55 – far more than most Lucky 15 combinations with the same total outlay.
Consider what is on the card. A day of competitive handicaps is not Lucky 15 territory. A day with four races where you have genuine strong opinions is exactly where the Lucky 15 earns its place.

FAQs
What is a Lucky 15 in horse racing?
A Lucky 15 is a multiple bet consisting of 15 individual bets across four selections – 4 singles, 6 doubles, 4 trebles and 1 four-fold accumulator. All four selections must cover every possible combination, meaning just one winner guarantees a return.
How much does a Lucky 15 cost?
The unit stake is multiplied by 15. A £1 Lucky 15 costs £15. A 50p Lucky 15 costs £7.50. An each-way Lucky 15 doubles the cost as it contains 30 bets.
What is the difference between a Lucky 15 and a Yankee?
A Yankee contains 11 bets across four selections – doubles, trebles and a four-fold but no singles. A Lucky 15 adds four singles to create 15 bets. The key difference is that a Lucky 15 pays out on one winner; a Yankee requires at least two winners for any return.
What happens to a Lucky 15 with a non-runner?
The non-runner single stake is refunded. All other bets that included the non-runner are reduced by one leg – a four-fold becomes a treble, a treble becomes a double, a double becomes a single. The remaining selections continue as normal.
Should I bet win or each-way on a Lucky 15?
An each-way Lucky 15 is best when your selections include horses at 8/1 or bigger – the place returns provide meaningful insurance. For shorter-priced selections, a win-only Lucky 15 is typically better value as the each-way doubles the stake for a proportionally smaller improvement in likely return.
Which bookmaker is best for a Lucky 15?
Betfred consistently offers the best Lucky 15 bonus – treble odds if only one horse wins and a 10% bonus if all four win. This makes a significant difference to returns, particularly on the one-winner scenario where the difference between double and treble odds is substantial.
