Last checked 21 October 2026 by Tom Perkins. Updated version of our Lucky 15 guide, now with a calculator. No operator-specific bonuses are stated.
A Lucky 15 is 15 bets on 4 selections: 4 singles, 6 doubles, 4 trebles and 1 four-fold accumulator. A £1 win Lucky 15 costs £15. Each-way, it is 30 bets, so £30 at £1 each-way.
The calculator defaults to a Lucky 15. Choose the result of each selection, and tick each-way if needed.
What’s in a Lucky 15?
| Bet | Number | Needs |
|---|---|---|
| Singles | 4 | One selection to win |
| Doubles | 6 | Both in a pair to win |
| Trebles | 4 | All three in a group to win |
| Four-fold | 1 | All four to win |
| Total | 15 |
Because singles are included, one winner gives a return. Whether that covers your £15 depends on the odds. A single 5/1 winner on a £1 Lucky 15 returns £6.
Worked example (illustration only)
£1 win Lucky 15, four selections all at 2/1 (decimal 3.0), all win:
| Bets | Each returns | Subtotal |
|---|---|---|
| 4 singles | £3 | £12 |
| 6 doubles | £9 | £54 |
| 4 trebles | £27 | £108 |
| 1 four-fold | £81 | £81 |
| Total | £255 |
You can check this in the calculator above. If one of the four loses, every double, treble and four-fold containing it loses too.
Each-way Lucky 15
An each-way Lucky 15 adds 15 place bets using each selection’s place odds. A selection that wins counts in both the win and place lines; one that only places counts only in the place lines. See each-way betting explained for place terms.
Lucky 15 vs Yankee, Lucky 31 and Lucky 63
| Bet | Selections | Bets | Includes singles? |
|---|---|---|---|
| Yankee | 4 | 11 | No |
| Lucky 15 | 4 | 15 | Yes |
| Lucky 31 | 5 | 31 | Yes |
| Lucky 63 | 6 | 63 | Yes |
See our full-cover bets hub for every type.
If you only want the four-fold, that is a straight accumulator. On horse racing, a non-runner in your Lucky 15 is treated as void in each bet it appears in, and any Rule 4 deduction applies to the legs that run.
Lucky 15 bonuses
Some bookmakers add their own extras to Lucky 15s, such as bonuses for one winner or all four. These are promotions that vary by operator and can change, so we don’t list them here or include them in the calculator. Check the bookmaker’s current terms. Non-runners in a Lucky 15 are usually treated as void legs, so the remaining bets run on the other selections.

Frequently asked questions
How many selections are in a Lucky 15? Four, in separate events.
What is the minimum stake? It depends on the bookmaker. The total cost is 15 × your unit stake (30 × each-way).
What happens if one selection is a non-runner? It is usually treated as void: singles on it are refunded and multiples run on the remaining selections. Check the bookmaker’s rules.
Can I place a Lucky 15 on football? Usually yes, on four selections from different events. Some bookmakers restrict multiples on related selections.
Is a Lucky 15 better than an accumulator? Neither is better. A Lucky 15 costs more and spreads the risk; an acca is one bet that needs every leg to win.
