A Lucky 31 is an extension of a Lucky 15 bet in that it is based around five selections incorporating a total of 31 bets. It is composed of five single bets, 10 doubles, 10 trebles, five four-folds and a five-fold accumulator.
Much like a Lucky 15 and Lucky 63 bet, understanding the full coverage of the bet can be complicated but the rewards can be vast, making it appealing to punters and to bookmakers as the odds of a big win are much more in the bookies favour.
Bookmakers also offer a number of bonuses on Lucky 31 bets which are paid out as a percentage on top of winnings usually in the region of 10 – 20%.
A Lucky 31 bet is more commonly made in horse racing events but can be made on other sports and is similar to a Canadian.
How is Lucky 31 used in Sports Betting?
An example of Lucky 31 betting would be to make five selections on five races at a chosen race meeting.
Those five selections incorporate 10 doubles, 10 trebles, five four-folds a five-fold accumulator and five single bets all inside the five selections, with the punter making the choice across all 31 individual lines.
The best thing about a Lucky 31 bet is that the punter only needs one of the five selections to win in order to start to see a return, but similar to a lucky 15 bet, because essentially 31 lines are being bet on, it would mean a £1 bet on each selection would cost a total of £31 total stake.
Did you know…
Prior to making a Lucky 31 bet, most punters use a Lucky 31 calculator in order to work out potential profits and profits per individual line due to the element of not requiring all selections to be winners to claim a return.
