Examples
Football (decimal odds)
Teams A 2.00, B 2.20, C 2.40, D 2.60 → 15 bets (incl. singles). Even 1 winner returns via its single.
Horse racing (fractional odds)
Horses at 2/1, 9/4, 5/2, 7/2 in a Lucky 15.
Fractional odds explained
- Written as a/b (e.g., 5/2). This means you win a profit of a for every b you stake.
- Profit = stake × (a ÷ b). Total return = stake + profit.
- Quick convert to decimal: 1 + (a ÷ b). Example: 9/4 → 1 + 9/4 = 3.25.
- Example: at 2/1, a £10 stake: profit £20, total return £30.
Formulas
Singles
Each single: Return = stake × odds.
Doubles
Each double: Return = stake × odds of pick 1 × odds of pick 2. Add all doubles.
Trebles
Each treble: Return = stake × odds1 × odds2 × odds3. Add all trebles.
4-folds
Each 4-fold: Return = stake × multiply the odds of 4 selections. Add all 4-folds.
Total return = add up the returns from all of the above component bets.
Reasons for making a Lucky 15 Bet
- Increased chances of winning: Multiple combinations create more ways to get a return than a single bet.
- Potential for significant returns: When several selections win, combined payouts can grow quickly.
- Risk management: Some combinations can still return even if not all selections win.
