Understanding Lucky 15 Bets
4 Singles
Four individual bets, one on each selection. This is what makes Lucky 15 different from Yankee - you get a return with just 1 winner.
6 Doubles
All possible combinations of 2 selections from your 4. Each double requires both selections to win.
4 Trebles
All combinations of 3 selections. Each treble requires all 3 selections to win.
1 Four-fold
One accumulator with all 4 selections. All must win for this bet to pay out, but it offers the highest potential return.

Pro Tips
Use Bookmaker Bonuses
Always place Lucky 15 bets with bookmakers offering bonuses. The 10% all-winner bonus and double-odds consolation significantly improve expected value.
Consider Outsiders
Lucky 15 is ideal for backing higher-priced selections. The singles provide protection if only one wins, while all 4 winning at bigger prices delivers huge returns.
Compare to Yankee
If you're confident 2+ selections will win, a Yankee at 11 units is cheaper. Use Lucky 15 when you want protection from just 1 winner scenarios.
