What is Lucky 15?
A Lucky 15 bet is basically a wager that covers every possibility within multiple betting across four selections.
It's a particularly popular wager when betting on horse racing and means you're making 15 separate bets, hence the name Lucky 15.
The Lucky 15 is growing increasingly common with bettors today as you can earn some serious money if even just a one or two of your selections come through. Do be aware though, because you are placing 15 bets, you're also need 15x stake money.
