What is a Lucky 31?
A Lucky 31 takes five selections and covers every combination of them: five singles, ten doubles, ten trebles, five four-folds and one five-fold — 31 bets, so €31 at €1 a bet, or €62 each way.
It is the Lucky 15 with one more leg, and that leg roughly doubles the cost. In return, every extra winner is multiplied into many more bets: with five short-priced winners the four-folds and the five-fold do most of the paying, while one or two winners mostly return the singles and a double.
| Bet | How many |
|---|---|
| Singles | 5 |
| Doubles | 10 |
| Trebles | 10 |
| Four-folds | 5 |
| 5-fold accumulator | 1 |
| Total | 31 |
How much does a Lucky 31 pay? A worked example
Three winners, a loser and a void leg, €1 a bet: Evens (2.00, won), 6/4 (2.50, won), 2/1 (3.00, won), 5/2 (3.50, lost), 4/1 (5.00, void). The Lucky 31 costs €31.00 and returns €83.00 — a profit of €52.00. The figures above are the calculator's own: change any price or result to see how the return moves.
Football selections
These bets started on the racecourse but settle the same on football: a selection is any call at its price — a result, over 2.5 goals, both teams to score, an outright. Every leg carries the bookmaker's margin, and multiples multiply it, so the margin calculator is worth a look before you choose prices, and our match predictions put the model's calls beside the bookmaker's prices — the day's Free Picks open to everyone. For one straight multiple, use the accumulator calculator.
