What is a Lucky 15 Bet?

Those who have placed bets on horse racing before will be very familiar with the Lucky 15 bet, or will at least have heard the term before. This bet consists of four selections, usually which horses will win certain races, and these are spread out over 15 individual parts:

  • 4 Singles
  • 6 Doubles
  • 4 Trebles
  • 1 four-fold accumulator

A single win from any of the four selections ensures a return as the lucky 15 bet consists of four singles. However, it might not be as much as the original stake depending on the odds. You can place Lucky 15 bets across several sports, though it is most used on the best horse racing betting sites.

The cost of a Lucky 15 bet is always 15x your stake, as you are placing 15 different bets. For example, a £1 stake on a Lucky15 bet would cost £15. On some of the best betting sites, there are winner bonuses to increase your returns if you win all four selections, lose the bet by one, or a one-winner consolation bonus.

We recommend also checking each betting site to see what horse racing bonuses are offered in general (that often also can be used for lucky 15 bets).

How to Place a Lucky 15 Bet

Placing a Lucky 15 bet is not as straightforward as a single bet, but UK betting sites have certainly simplified the process for punters. In fact, you just need to add four selections to the bet slip and browse the multiples options, where Lucky 15 should be listed. All that remains after that is to enter a stake for the bet.

It should be noted that the stake will be multiplied by 15, as already explained, and this could make the bet rather costly. Even just a £1 stake will result in a £15 cost, so punters should definitely double-check the total stake before placing the bet. On the other hand, there is also the chance to win more money with a Lucky 15 bet.

You might wonder how a Lucky 15 bet actually works in practice, so we have put together an example below. It is based on four horses to win separate races and it looks as follows:

  • 4 Singles

    • Horse A to win
    • Horse B to win
    • Horse C to win
    • Horse D to win
  • 6 Doubles

    • Horse A + Horse B to win
    • Horse A + Horse C to win
    • Horse A + Horse D to win
    • Horse B + Horse C to win
    • Horse B + Horse D to win
    • Horse C + Horse D to win
  • 4 Trebles

    • Horse A + Horse B + Horse C to win
    • Horse A + Horse B + Horse D to win
    • Horse A + Horse C + Horse D to win
    • Horse B + Horse C + Horse D to win
  • 1 Four-Fold Accumulator

    • Horse A + Horse B + Horse C + Horse D to win
