The lucky 31 is a 5 selection bet consisting of 31 bets: 5 singles, 10 doubles, 10 trebles, 5 four-folds and a five-fold accumulator.
Named after its 31 parts and the wide variety of bookmaker bonuses to be had, the lucky 31 is a popular wager. 'All winners', 'one loser' and 'one winner' are the scenarios to which most bookmakers apply a bonus. Each way bets are usually excluded from this. Ask in shop or check the online terms and conditions to find an accurate bonus listing.
The order in which bets appear on the slip is unimportant because each of the 5 selections appears the same amount of times across all 31 bets.
Winnings can be worked out by hand but using the lucky 31 calculator on this site takes much less time. Try out different odds, stakes and outcomes to get a feel for how returns are affected.
If one or more selections win this bet will generate a return.
The lucky 31 is composed of the following parts:
|Part||Selection Permutations (1-5)||Number of Bets|
|Single||1, 2, 3, 4, 5||5|
|Double||12, 13, 14, 15, 23, 24, 25, 34, 35, 45||10|
|Treble||123, 124, 125, 134, 135, 145, 234, 235, 245, 345||10|
|Four-Fold||1234, 1235, 1245, 1345, 2345||5|
