Lucky 31 Calculator

Thirty-one bets on five selections

A Lucky 31 covers five selections with every possible combination: 5 singles, 10 doubles, 10 trebles, 5 four-folds and 1 five-fold. At £1 a bet that is a £31 stake, or £62 each way. It is the Lucky 15 with a fifth selection added, and a Canadian with the five singles put back in.

The bonuses are bigger, and so is the hole

Bookmakers typically pay double the odds on a single winner and a 20% bonus if all five win — double the Lucky 15’s usual 10%. The calculator defaults to both, and both are adjustable.

The larger bonus is doing less work than it looks. Because the stake has more than doubled while the consolation stays at one enhanced single, a lone winner leaves you further behind than the same result in a Lucky 15.

Worked example

Five selections at decimal odds of 3.00, 4.00, 5.00, 6.00 and 7.00, £1 per bet, so £31 staked.

• All five win: £8,062.80 with the 20% bonus applied.
• One wins (the 3.00): £6 back at double the odds — a £25 loss on a £31 stake.

Compare that second line with a Lucky 15, where the identical result costs you £9 rather than £25. Adding the fifth selection roughly doubles your stake, and the consolation bonus does not grow with it.

Lucky 31 or Canadian?

Same five selections, but a Canadian (also called a Super Yankee) drops the singles: 26 bets instead of 31. It is £5 cheaper at £1 a bet, and in exchange one winner returns nothing at all. If you think one or two of your five might come in, the Lucky 31 is the one with a floor under it. If you are confident of three or more, the Canadian keeps your money on the bets that will actually pay.

You can switch between the two in the bet type dropdown above and compare the same odds side by side.

Thirty-one bets means the bookmaker’s margin is applied thirty-one times over. Bonuses do not offset that. 18+ only. Please gamble responsibly.
