What is a lucky 31?

A Lucky 31 is, as the name indicates, a combination of 31 bets put into 1 system. It works exactly like a Canadian bet/Super Yankee, but the difference is the added security of also playing singles. When placing a Lucky 31, you are betting on 5 outcomes in 5 different events on 31 betslips which are split into 5 singles, 10 doubles, 10 trebles, 5 fourfold accumulator and 1 fivefold accumulator. At least 1 of the outcomes must be correct for you to get a return on the Lucky 31. The winning odds are either multiplied with each other or the stake to determine your return.

Example of a lucky 31

For example, if you play a Lucky 31 with a stake of £1 on each betslip (£31 in total) on Everton to beat Leicester at odds 1/1 (Evens), Sevilla to beat Valencia at odds 6/4, Arsenal to beat Tottenham at odds 6/4, Barcelona to beat Atletico Madrid at odds 1/1 (Evens) and Manchester City to beat Liverpool at odds 1/1 (Evens) your return can range from £2 to £329.75 depending on which teams win their respective matches. If none of the teams win their match your stake is lost.

Pros and cons of a lucky 31

The pro of a Lucky 31 is that it is a very secure way of betting because you only need 1 correct outcome to get a return. The con of a Lucky 31 is that you need a big bankroll and a lot of experience with this betting type to be successful.

How to use the bet calculator

It's easy to use the Unibet Betting Odds Calculator. First, you need to decide which type of bet you want, of which we have many, from singles, accumulators to Goliaths and Lucky 15s, 31 s and 63s.

Once you've chosen, select your bet type on the calculator (which we've broken out with easy navigational links in the menu) and then decide if you want the odds to be displayed in a fractional or decimal format in the top right corner.

After that, you'll need to input your stake - how much you want to bet. You'll then want to decide if that bet is each way, add any rule 4s, and whether you want to see the selection notes or fold options. We've put a tooltip text over some of these, to give you some explanation if they're unfamiliar. Finally, enter the odds and the outcome: Winner, Lost, Void and/or Dead Heat. If there are multiple selections you would like to make, enter the odds for each one. Simply click the 'Calculate Now' option and both your potential return and profit will be displayed for you.
