What is a Lucky 15 bet?

A Lucky 15 consists of fifteen bets involving four selections from different events, combining 4 singles, 6 doubles, 4 trebles and 1 accumulator. You need only one winner to guarantee a return.

In the event of one winner only, your winnings are doubled.

For four winners out of four a bonus of 10% is generally added to winnings on the win part of the bet (winnings = the return for the win part of the bet minus the win stakes for that bet).

If a Lucky 15 is placed on horse racing and it contains a non runner no bonuses will apply to that bet.

For example, if the 4 selections and their odds were:
A = 2.00    B = 3.50    C = 4.00    D = 1.50

(Fractional equivalent: Evens, 5/2, 3/1 & 1/2)

  • If all four selection wins,  you would win on all fifteen bets.
  • If three selections wins and the other one loses, you would win on 7 bets (3 singles, 3 doubles, 1 treble).
  • If only two selection wins, you would win on 3 bets (2 singles and 1 double).
  • If only one selections wins, you would win on 1 bet (1 single).

Example 1. If all 4 selections won in a £1 Lucky 15 the winnings would be calculated as the following:

4 x Singles

A2.00= 2.00
B3.50= 3.50
C4.00= 4.00
D1.50= 1.50

6 x Doubles

A + B2.00 x 3.50= 7.00
A + C2.00 x 4.00= 8.00
A + D2.00 x 1.50= 3.00
B + C3.50 x 4.00= 14.00
B + D3.50 x 1.50= 5.25
C + D4.00 x 1.50= 6.00

4 x Trebles

A + B + C2.00 x 3.50 x 4.00= 28.00
A + B + D2.00 x 3.50 x 1.50= 10.50
A + C + D2.00 x 4.00 x 1.50= 12.00
B + C + D3.50 x 4.00 x 1.50= 21.00

1 x Accumulator

A + B + C + D2.00 x 3.50 x 4.00 x 1.50= 42.00

Example 2. Using the same odds and stake as above, if only selection C won and the other 3 selections lost, the winnings would be calculated as following:

The only winning bet would be the single on Selection C, all other single and multiple bets would be losers.

With only 1 winner your winnings are doubled, therefore:

£1 x £4.00 (payout) — £1 (stake) = £3.

Winnings on selection C with bonus

£3 x 2 = £6.00.

Payout on selection C with bonus

£6 (winnings) + £1 (stake) = £7.00

The cost of the bet is £15.00, leaving a loss in this instance of £8.00.

BetVictor Horse Racing Bonus


Lucky 15 is particularly suited for horse racing and greyhounds betting, but there are no particular limitations if you want to place a lucky 15 bet on football or other sports.

Anyway, you must be careful about the markets and the odds to select. For instance, rather than Match Winner or BTTS markets, it’s generally advised to go for football betting markets such as 1st Goalscorer or Correct Score where odds are at least 5.00 (or 4/1). Darts and snooker are good sports if you’re having a Correct Score bet on a selection of matches.

Of course, you can also place Lucky 15 bets on each-way markets, but bear in mind that a £1 e/w Lucky 15 will cost you £30 rather than £15 as you are betting on "to win" and "to place" markets.


All bookmakers will offer Lucky 15 bets with a number even offering bonuses and money back specials on the bet.
