What is a Lucky 15 bet?
A Lucky 15 is 15 bets across 4 selections: 4 singles, 6 doubles, 4 trebles and 1 four-fold accumulator. You don’t need all four to win — a single winner still returns something — which makes it a popular each-way staple in horse racing.
Example
4 horses at £1 per line = £15 total. One winner pays its single (bookies often add a bonus for one winner); all four winning pays every one of the 15 bets.
