The Lucky 15 bet is a type of combination and system wager that British punters can use on sports with four selections put together on the same betslip as four singles, six doubles, four trebles and a fourfold accumulator. In this article, you’ll learn everything you need to know about Lucky 15s. We’ll cover what they are, how they work, and even give you some top tips on winning them.

What a Lucky 15 Bet is and How it Works

A Lucky 15 bet is 15 individual bets across 4 selections and it consists of four singles, six doubles, four trebles and one four-fold accumulator. But lets look into more details.

All sports bets can be broken down into two categories: singles and multiples. Singles only contain one selection, and multiples contain two or more.

Within the second category, there are two main variants: simple multiples, and complex multiples. Simple multiples include regular doubles, trebles, and accumulators. Complex (or ‘exotic’) multiples have a few of their own varieties, such as Trixies and Yankees.

A Lucky 15 bet is one of the most famous complex multiples. It’s ‘complex’ because it requires a diverse range of outcomes to come true in order for the whole bet to hit. Unlike a simple multiples wager, these will include a range of different bet types.

As the name implies, a Lucky 15 bet will consist of 15 different selections. These consist of:

Those wagers will be spread across four separate sporting events, which – usually – means four different horse races.

This is how lucky 15 bet may look like on a football accumulator. The stake as little as £1 can yield up to £140 in return.

How to Work Out a Lucky 15 Bet?

With a hefty 15 different outcomes involved, it’s better not to try working out these bets for yourself. Save yourself the trouble by using a Lucky 15 bet calculator, which many top brands include by default on their websites.

With that said, if you’re serious about Lucky 15 bets, you should still know how these calculations are actually made.

For starters, you’ll want to use decimal odds rather than fractional ones, which makes your sums much easier. After that, the calculation itself depends on which part of the overall bet you’re focusing on.

For the singles parts, you simply multiply your stake by the decimal odds to calculate your return, as normal. As for the doubles, you multiply the odds for the first selection by those for the second selection (e.g. A x B). For the trebles you do this for all three selections (A x B x C), and – naturally – by all four for the four-fold (A x B x C x D). When calculating the multiples parts, be sure to factor your initial stake into your potential returns.

In short, that’s how to calculate your returns on a complete, winning Lucky 15 bet. If you want to calculate your returns for one, two, or three winning selections instead, simply remove three, two, or one successful outcomes respectively from the equation.

How to Win a Lucky 15 Bet

Lucky 15 bets might sound complicated, but they’re actually a little more forgiving than certain other multiples. That’s because you don’t actually need to win every single selection in order to make a return.

As noted, Lucky 15’s include singles bets. These cover four different outcomes, and actually act independently of the other parts of your wagers (doubles, trebles, and four-folds). If any of these win, therefore, you will get money back on your bet. Do be aware, however, that – if only one selection comes in – you won’t usually make a profit. You’ll simply recoup some of your original stake.

To make some real money here – which we’d count as an actual ‘win’ – you’ll require some of those higher-stakes selections to triumph. Exactly what you need to happen depends on your odds and stake. Again, if you have a high quality Lucky 15 calculator handy, this is something you can work out using that tool.

5 Key Lucky 15 Betting Tips

Lucky 15’s might not be as difficult to win as other multiples, but they’re still tricky customers. There are steps you can take to either improve your chances of success or boost your winnings, however, with these being five of the most useful.

Tip 1: Choose the Right Bookie

This is something you must absolutely do ahead of time, or you’ll regret it further down the line. To get started as quickly as possible, simply pick one of our recommended Lucky 15 betting sites. If you want to go your own way, make sure you put plenty of time into doing your research. Naturally you must ensure your chosen bookie provides Lucky 15 wagers, but you should also analyse the quality of its odds, breadth of its market selection, speed of its payouts, and more.

Tip 2: Search for Special Offers

Lucky 15 bonuses definitely aren’t ‘common’, but they’re not unheard-of either. Take advantage of these wherever you do find them. The best will give you bonuses on your winnings, which can equal up to 2x – or even 3x – the regular profits you’d have received. If you’re feeling particularly confident, these sites will often provide bonuses on Lucky 31’s and Lucky 63’s too.

Tip 3: Do Your Research

Lucky 15’s require a bigger budget than regular wagers (see below). Accordingly, you should put even more effort into your research for each bet than normal. This can be done manually, by looking at form, conditions, odds, and so on. Alternatively, there are dozens of good sites out there which specialise in horse racing predictions, and many of these will dish out Lucky 15 betting tips too.

Tip 4: Lower Your Stakes

Lucky 15’s consist of 15 different selections. This means that – whatever your initial stake is – it will be multiplied 15x. Even if you use a £0.10 stake, for example – which is a common minimum amount – you’ll still be betting £1.50 in total. As such, you’ll definitely want to lower your stakes for Lucky 15’s compared to your regular singles and multiples.

Tip 5: Try Each Ways

Each ways are very popular horse racing wagers, giving returns on both the ‘win’ and ‘place’ parts. Technically you can place each ways on Lucky 15’s too, thus also improving your chances of making a return, although they work a little differently. Instead of being one combined bet, the ‘win’ and ‘place’ parts are split into two separate wagers for each selection. As such, you actually end up with 30 total selections (and your stake is also multiplied by 30, of course).

What to Look for When Betting Online With a Lucky 15 Bet

As a UK punter, you are surely in luck when it comes to sites to place a Lucky 15 bet, as there are a lot to pick and chose from – so here are some base criteria we think you can use to find a good bookie.

  • Safety

This is one of the first things you should look into on any gambling platform. Today, most bookies that are active in the UK holds a license from a reputable regulatory body. Check for the basics above that, like SSL encryption and 2FA to make sure that when you place that Lucky 15 bet, your money and account are safe.

  • Odds

All Lucky 15 bets should take your odds up to pretty high levels. There’s still some significant variation, however, between the specific prices you might be offered for the same wager. You can look to compare odds in our recommended betting sites to those provided by their competitors. In each case they were at least as good, if not better, than those other bookies, and also featured competitive margins.

  • Market Selection

Across almost all variations of sports betting, the more options you have, the better. Lucky 15 market selections tend to be a bit more limited, with this bet type typically being used on horse racing. Still, even within that subsection, we like to see a nice, wide variety of betting opportunities. All races across the UK and Ireland should usually be provided by default, but the top bookies might also cover those in the USA, South Africa, France, and elsewhere around the world.

  • Special Features

There’s obviously a limit on the number of special features you can have specifically for Lucky 15’s. One tool which is very useful indeed, however, is a Lucky 15 calculator. This should not just calculate basic odds, but should be highly customisable and flexible. You should be able to change the odds for each part of the bet, change the outcomes of each selection, vary your stakes, and so on, with your potential returns updating immediately as you do so.

Elsewhere, it’s obviously desirable to have a few other special features in place. The likes of betting previews can really improve your Lucky 15 betting, for example, and live streaming will certainly make it more fun.

  • Bonus Offers

As with special features, it’s pretty rare for bookies to offer specific promotions for Lucky 15 wagers. The more bonus offers you have available to you though, the further your money will go in your other sports betting.

When checking out a bookie’s special offers, we suggest looking at a few key areas. These include clarity of the T&Cs, the fairness they actually represent, and the overall value which is being provided. In the best cases, these deals should either help you make more money (like an Acca Boost), or avoid losing it (like Acca Insurance), while not containing any annoying ‘catches’.

On Where to Bet on a Lucky 15

You may still have many more questions, which is fine – no one is a master in one fell swoop, or one guide read. As a start, familiarize yourself with what bookmakers are available in the UK and what they offer. If you go to the first page of you can find many useful links and reviews that will be a good start at finding the best betting sites and their offering.
