A Lucky 31 is a full-cover multiple bet on five selections containing 31 individual bets: 5 singles, 10 doubles, 10 trebles, 5 four-folds, and 1 five-fold accumulator. It covers every possible combination from five selections and guarantees a return from a single winner through the singles component.
Structure summary:
- Singles: 5
- Doubles: 10
- Trebles: 10
- Four-folds: 5
- Five-fold: 1
- Total: 31
Cost: at £1 per line, a Lucky 31 costs £31. At smaller unit stakes (e.g. 10p per line), the cost is £3.10 — making it accessible for bettors who want full coverage without large outlay.
The Lucky 31 is popular among horse racing bettors who identify five strong selections across a day's card. The full coverage means no selection is wasted — every winner contributes to at least one winning bet, and the cumulative effect of multiple winners creates exponentially larger returns through the accumulators.
Comparison to Super Heinz: the Super Heinz covers 7 selections (120 bets) but has no singles. The Lucky 31 has 5 selections with singles. For bettors who want singles coverage on a larger selection count, the Lucky 63 (6 selections) is the next step up.
Example
£1 Lucky 31 (£31 total). Three of five selections win at odds of 3.0, 4.0, and 5.0. Returns from applicable combinations: 3 singles (£3+£4+£5=£12), 3 doubles (£12+£15+£20=£47), 1 treble (£60). Total return = £119. Profit = £119 - £31 = £88 from three winners.
