How a lucky 31 settles
A lucky 31 is 31 bets on five selections: five singles, ten doubles, ten trebles, five four-folds and one five-fold. A £1 lucky 31 costs £31; £1 each way costs £62. One winner gives a return through its single.
Worked example: £1 lucky 31 with winners at 2/1, 3/1 and 4/1 and two losers. The 5 singles return £12.00, 10 doubles return £47.00, 10 trebles return £60.00. Every four-fold and the five-fold lose. Total return £119.00 from £31.00.
The worked examples on this page are settled by the same calculator you can use above, so the figures match it to the penny.
The rules we use
These are the standard UK settlement rules. Where bookmakers differ, we use the commonest rule and say so. Your bookmaker's own rules decide your bet.
- Each way
- An each-way bet is two bets of the same stake: one to win at the full odds, one to place at the place fraction of the odds. A winner pays both. A horse that only places pays the place bet.
- Each-way multiples
- The win part needs every horse to win. The place part needs every horse to win or place, and a winner counts at its place odds there.
- Non-runners and voids
- A non-runner or void leg counts as odds of 1.0: in a single you get your stake back, and in a multiple that leg drops out, so a double becomes a single, a treble a double, and so on.
- Rule 4
- The deduction comes off the winnings only, never the stake, and only on the leg it applies to. The place part is worked from the reduced win odds. Deductions above 90p in the pound are refused, because the rule caps them there.
- Dead heats
- The stake on that leg is divided by the number of horses tied, then multiplied by the number of tied places that are still paid. A dead heat for 1st halves the win part. Two tied for the last place paid halves the place part.
- Rounding
- Everything is worked out exactly and only the total return is rounded, down to the penny, as most bookmakers do. Each line in the breakdown is rounded down on its own, so the lines can come to a penny more than the total.
- Bonuses
- Bonuses and consolation payouts on lucky 15s, lucky 31s and similar bets vary from bookmaker to bookmaker, so none are included. Check your own bookmaker's rules.
- Total stake
- If you enter a total stake, it is shared equally across every bet in the bet (and across both halves of an each-way bet).
Questions
How many bets are in a lucky 31?
Thirty-one: 5 singles, 10 doubles, 10 trebles, 5 four-folds and a five-fold on five selections.
What is the difference between a lucky 31 and a Canadian?
A Canadian (or super yankee) is the same bet without the singles: 26 bets that need two winners.
Are bonuses included?
No. Many bookmakers pay a bonus for one winner or for all five, but the terms differ between them, so the calculator settles the 31 bets only.
