Lucky 31 Calculator
31 bets on 5 selections — singles up to the five-fold, plus bonuses.
A Lucky 31 is 31 bets from 5 selections (5 singles, 10 doubles, 10 trebles, 5 four-folds, 1 five-folds). Void/non-runner legs settle at 1.00, shrinking any line they're in. Each-way doubles the stake and pays a place accumulator at each leg's terms.
How a Lucky 31 works
A Lucky 31 is thirty-one bets on five selections: five singles, ten doubles, ten trebles, five four-folds and the five-fold. It's the five-selection version of the Lucky 15 — singles included, so one winner returns, and usually with bonuses attached. The all-winners bonus is typically larger than a Lucky 15's, reflecting the tougher ask of landing five.
Worked example: a £1 Lucky 31 costs £31. Five winners at evens return £242 before the bonus; a 20% all-winners bonus lifts that to £290.40. As with any Lucky bet, a lone winner has its odds boosted instead — set both figures to match your bookmaker.

FAQ
Lucky 31 or Canadian?
Both use five selections, but the Canadian drops the singles (26 bets); the Lucky 31 keeps them and adds bonuses (31 bets).
Is the bonus on winnings or returns?
This calculator applies the all-winners percentage to your total return. Books differ, so treat it as a guide and check the promotion's wording.
Can I run it each-way?
Yes — the stake doubles and a place Lucky 31 runs alongside at each leg's terms.
Five legs is a lot of margin to overcome at once — the case for taking each price at its best on the odds comparison only gets stronger. The six-selection step up is the Lucky 63.
