What is a Lucky 15 Bet?
A Lucky 15 is one of the most popular multiple bets in UK betting, particularly for horse racing and football. It consists of 15 separate bets covering all possible combinations of 4 selections:
- 4 Singles - One bet on each selection individually
- 6 Doubles - Six bets combining each pair of selections
- 4 Trebles - Four bets combining each group of three selections
- 1 Four-fold Accumulator - One bet on all four selections together
The beauty of a Lucky 15 is that you can still get returns even if only one or two of your selections win, unlike a standard accumulator which requires all selections to be successful.

Lucky 15 Bonuses from UK Bookmakers

Consolation Offers
Some bookies offer money back or free bets if you land 3 out of 4 winners but miss out on the big return.

Lucky 15 Betting Strategy Tips
1. Target the Sweet Spot for Odds
For optimal Lucky 15 returns, experienced UK punters typically look for selections with odds between 2/1 and 7/1 (3.0 to 8.0 decimal). This provides a good balance between probability and potential returns. Shorter odds mean you need multiple winners to make a profit, while longer odds are harder to land but offer exponential returns.
2. Consider Each-Way Lucky 15s for Horse Racing
Each-way Lucky 15s double your stake (30 bets total) but provide excellent coverage for horse racing. You get returns on placed horses even if they don't win. Place terms are typically 1/4 or 1/5 of the win odds for 2-4 places depending on field size. This is particularly valuable at competitive race meetings like Cheltenham or Royal Ascot.
3. Shop Around for the Best Bonuses
Different UK bookmakers offer varying Lucky 15 bonuses. Compare offers from Bet365, William Hill, Paddy Power, Ladbrokes, and Coral. Some offer better double odds bonuses, others provide higher all-winners bonuses (ranging from 10% to 25%). Always check the minimum odds requirements - typically 1/5 or 2/5 per selection.
4. Mix Favorites with Value Selections
A popular strategy is to include 1-2 shorter-priced favorites (evens to 2/1) alongside 2-3 value selections at longer odds (4/1 to 7/1). This increases your chances of landing at least one or two winners while maintaining decent overall odds for the accumulator and trebles.
5. Understand Your Break-Even Point
To break even on a Lucky 15, you typically need at least 2 winners at decent odds. With average odds of 3/1 per selection, two winners will roughly cover your stake through the singles and the double. Use this calculator to experiment with different scenarios and understand when you'll profit.
6. Best Events for Lucky 15 Bets
Lucky 15s are particularly popular for:
- Saturday Horse Racing - Multiple meetings provide varied selections
- Football Accumulators - Weekend Premier League matches
- Major Race Meetings - Cheltenham Festival, Royal Ascot, Grand National day
- Evening Racing Cards - Midweek racing when bonuses apply
Lucky 15 vs Other Multiple Bets
| Bet Type | Selections | Total Bets | Key Feature |
|---|---|---|---|
| Lucky 15 | 4 | 15 | Singles included, bookmaker bonuses, returns from 1 winner |
| Patent | 3 | 7 | Smaller version, needs 1 winner minimum for returns |
| Yankee | 4 | 11 | No singles, needs minimum 2 winners for returns |
| Lucky 31 | 5 | 31 | Bigger version with 5 selections, higher cost |
| Four-fold Acca | 4 | 1 | Lower cost, requires all 4 to win, higher risk |
The Lucky 15 offers the best combination of coverage and value for 4 selections. While it costs more than a simple accumulator, the inclusion of singles means you can still profit with just 1-2 winners, and bookmaker bonuses add extra value.
Example Lucky 15 Calculation
Let's say you place a £1 Lucky 15 (total stake £15) on these horse racing selections:
- Selection 1: 3/1 (4.0) - WINS
- Selection 2: 5/2 (3.5) - WINS
- Selection 3: 4/1 (5.0) - LOSES
- Selection 4: 7/2 (4.5) - LOSES
Your Winning Bets (2 winners):
- Single on Selection 1: £1 × 4.0 = £4.00
- Single on Selection 2: £1 × 3.5 = £3.50
- Double (Selections 1+2): £1 × 4.0 × 3.5 = £14.00
Total Returns: £21.50
Total Stake: £15.00
Profit: £6.50
If your bookmaker offers a double odds bonus on one winner, or if both remaining selections had also won, your returns would be significantly higher due to the trebles and four-fold accumulator kicking in!
Common Lucky 15 Mistakes to Avoid
Choosing All Short Odds
Selecting four favorites at odds like 1/2 or evens means you'll likely need all four to win just to break even. The returns won't justify the 15-bet stake. Mix in some value selections at longer odds.
Picking Four Long Shots
While the potential returns from four 20/1 selections are massive, the probability of landing even one winner is very low. Balance your selections with at least one or two more realistic chances.
Ignoring Minimum Odds for Bonuses
Many UK bookmaker bonuses require minimum odds of 1/5 or 2/5 per selection. If your selections don't meet this, you won't qualify for double odds or all-winners bonuses. Always check the terms before placing your bet.
Not Understanding the Total Stake
New bettors sometimes don't realize that a £5 Lucky 15 costs £75 total (15 bets × £5). Always be clear on your unit stake and total outlay before confirming the bet.
Choosing Correlated Selections
Picking all four selections from the same race or heavily correlated events (like four home favorites in one league gameweek) reduces the independence of your bets. Diversify across different races, matches, or sports for better coverage.
Frequently Asked Questions
What is a Lucky 15 bet?
A Lucky 15 is a popular UK betting wager consisting of 15 bets across 4 selections: 4 singles, 6 doubles, 4 trebles, and 1 four-fold accumulator. It's called 'lucky' because most UK bookmakers offer bonuses for one winner (typically double odds) or consolation for all losers in one-result scenarios.
How much does a Lucky 15 bet cost?
A Lucky 15 bet costs 15 times your unit stake. For example, a £1 Lucky 15 costs £15 total (15 bets × £1), while a £2 Lucky 15 costs £30 total. Each of the 15 individual bets is placed at your chosen unit stake.
Do I need all 4 selections to win for a Lucky 15 return?
No! That's the beauty of a Lucky 15. You can still win with just 1, 2, or 3 winners. With 1 winner, you get returns from the single bet (often doubled by bookies). With 2 winners, you get the singles plus the double. More winners means exponentially higher returns as trebles and the accumulator come into play.
Which UK bookmakers offer the best Lucky 15 bonuses?
Most major UK bookmakers including Bet365, William Hill, Paddy Power, Ladbrokes, and Coral offer Lucky 15 bonuses. Common offers include: double odds for one winner, 10% bonus for all four winners, and consolation refunds if only one selection loses. Always check terms as bonuses vary and may require minimum odds (typically 1/5 or 2/5).
What are good odds for a Lucky 15 bet?
For UK horse racing Lucky 15s, experienced punters typically target selections between 2/1 and 7/1 (3.0 to 8.0 decimal). This balance provides decent returns without being too risky. Shorter odds (1/2 to evens) mean you need multiple winners to profit, while longer odds (10/1+) are harder to land but offer massive returns if successful.
Can I do each-way Lucky 15 bets?
Yes! An each-way Lucky 15 doubles your stake to 30 bets (15 for win, 15 for place). For a £1 each-way Lucky 15, you'd pay £30 total. This is popular for UK horse racing as you get place returns even if selections don't win, with place terms typically 1/4 or 1/5 odds for 2-4 places depending on the field size.
How do Lucky 15 bonuses work in the UK?
UK bookmakers typically offer: 1) Double odds bonus - if only one selection wins, winnings paid at double the odds; 2) Consolation - if all four selections lose except one that places (each-way bets); 3) All-winners bonus - 10-25% bonus added to total returns if all four selections win. Minimum odds requirements usually apply (commonly 1/5 or 2/5 per selection).
Is Lucky 15 better than a four-fold accumulator?
It depends on your risk tolerance. A four-fold accumulator costs less (1 unit stake vs 15) but requires all selections to win. A Lucky 15 costs more but provides insurance - you can still profit with 1-3 winners. For UK punters, Lucky 15s are popular for weekend football accumulators and Saturday horse racing as they offer better coverage and bookmaker bonuses.
