What the Lucky 15 Is All About
The Lucky 15 is a multi-bet package that bundles four selections into fifteen individual wagers: four singles, six doubles, four trebles, and a four-fold accumulator. By the way, it’s a favorite for punters who love high-risk, high-reward drama in a single ticket.
Step-One: Gather Your Odds
First, write down the decimal odds for each of your four horses. Look: 3.5, 5.0, 2.8, and 7.2 are common figures you might see on a race card. These numbers are the raw fuel for your calculation.
Step-Two: Break Down the 15 Bets
Here is the deal: you’ll calculate each component separately. Singles are easy — multiply stake by the odd, that’s it. Doubles require you to multiply the odds of any two selections together, then apply the stake. Trebles combine three odds, and the four-fold multiplies all four.
Example Numbers
Stake per bet: £1. Singles total: £1 × 3.5 + £1 × 5.0 + £1 × 2.8 + £1 × 7.2 = £18.5. Doubles: (3.5 × 5.0) + (3.5 × 2.8) + (3.5 × 7.2) + (5.0 × 2.8) + (5.0 × 7.2) + (2.8 × 7.2) = 21.2. Trebles: (3.5 × 5.0 × 2.8) + (3.5 × 5.0 × 7.2) + (3.5 × 2.8 × 7.2) + (5.0 × 2.8 × 7.2) = 107.1. Four-fold: 3.5 × 5.0 × 2.8 × 7.2 = 352.8.
Step-Three: Add It All Up
Now, sum every component. 18.5 + 21.2 + 107.1 + 352.8 = £499.6. That’s your gross return before the bookmaker takes a cut. And here is why the final figure matters: you’ll subtract the total stake (15 × £1 = £15) to see net profit.
Step-Four: Factor in the Bookmaker’s Take
Most platforms apply a commission on winnings, often 5 % on the accumulator portion. In our case, 5 % of £352.8 ≈ £17.64. Subtract that from the gross, then subtract the £15 stake. Net profit ≈ £467.0. That’s a solid win on a £15 outlay.
