Betting Terms Explained: Single Double Treble and Acca

In this first part of our Betting Terms Explained series Gaz breakdowns some of the most common bet types the single, double treble and accumulator and gives some handy tips on what to consider before placing your bet


For newcomers to the sports betting scene, getting to grips with the terminology used in the industry can be daunting. In our series Betting Terms Explained  we will clarify the most frequently used betting jargon and bet types as well as giving you some pointers on how to make sure you are getting the best value for your money. To begin with we will examine the type of bets that you will encounter most often in our  Horse Racing and Football tips sections.

The Single

A single is when you back one outcome in an event. Your selection must win in order for you to get paid out.

If you’ve ever placed a bet, the chances are it was a single. It’s the simplest and most common type of bet but it’s also one of the most important. If you are looking to build a long term profit (who isn’t?) then singles will be a core part of your betting strategy.

How to calculate:  Let’s say you put a €20 stake on Lazio to beat Juventus at odds of 2.5 and Lazio win 3-1. You can use the formula below to calculate your return. In this section we are using decimal odds. If you need help converting to fractions or American style odds, check out our handy conversion chart.

Stake x Odds = Return

€20 Bet @ 2.5 = €50 Return (€30 Profit plus your winning stake of €20 returned)

However if you are feeling lazy there are plenty of free bet calculators available online that will do all the hard work for you.

SRD Tip:   Shop around to find the best value.

There are numerous bookmakers and each will have markets priced differently. Always look for the best value and use the market competition to your advantage. Oddschecker is an odds comparison site that compares the prices all the major bookmakers are offering on different markets. It’s a useful tool that means you don’t have to check each bookmakers site individually.

Win and Place

A single can be either a “win” or “place” bet. Most singles fall into the “win” category, which means your selection needs to win in order to be paid out.

In sports such as Horse Racing, Greyhound Racing and Golf you will often see a “place” market. This means you can back a selection and will be paid if that selection does not win but comes close to winning.

Generally bookmakers offer a number of place markets where the bettor can select the number of places that aligns to their confidence in their selection. In Golf you will often see “Place 5” or “Place 10” markets. These are pretty self-explanatory, if selecting the place 5 market your selections needs to finish in the top 5 in order for you to receive a return. Similarly a bet made in the place 10 market will require the selection to finish in the first 10 places to be classed as a winner.

The prices in the place markets are adjusted by the bookmaker and do not have a standard calculation convention. The price will differ greatly depending on the selections probability of winning and the number of places chosen. For Example, if you back an even money favourite to finished in the the top 5, the return will be fairly paltry. Whereas if you were to back a 50/1 shot to finish in the top 2, the return could be quite favourable.

SRD Tip:  When betting in either the win market, or the place market, you should be familiar with “dead-heat” rules.


The Double

A double combines two outcomes in one bet. In betting terminology the selections are often referred to as “legs”. To be paid out both legs must win.

A double can be a risky play but the good news is that even though there are two selections, the stake isn’t impacted as both selections are classed as one bet.  The double can be a good way of adding some spice to lower priced selections.

How to calculate:  Imagine you put a €20 stake on Man United to beat Burnley at odds of 1.909 and Liverpool to beat Brighton at odds of 1.95. Both United and Liverpool win their games.

Stake x (Odds x Odds) = Return

€20 Bet @ 1.909  & 1.95 = €74.45 Return (€54.45 Profit plus your winning stake of €20 returned)

If instead you had bet the same €20 (€10 on each selection) across two singles your profit would have only been €18.59.

SRD Tip:  When placing a double make sure you understand the bookmaker terms.

This is particularly true when betting on Horse Racing as the concessions offered on single bets are not always replicated on multiples. One example would be Best Odds Guaranteed (BOG), which is a concession offered by many bookmakers. With BOG the bettor will be paid the higher price of (1) the price taken when placing bet (2) the Starting Price (SP) published post race. When placing a multiple (any bet with 2+ legs) it is wise to ensure that BOG is applied across all bets and not just singles.


The Treble

A treble has the same terms as a double with the obvious difference being there are three selections and not two. All three selections must win in order for the bet to be successful, getting 2 out of 3 selections correct is not good enough.

How to calculate: You staked €10 on Bayern Munich at odds of 1.333, Schalke at 1.8 and Wolfsburg at 1.833 all to win their respective matches. All three legs win.

Stake x (Odds x Odds x Odds) = Return

€10 @ 1.333  & 1.8 & 1.833 = €43.98 (€33.98 Profit plus your winning stake of €10 returned)

SRD Tip:  Keep an eye out for the bonus.

Some bookmakers offer a bonus for bets that contain three or more legs. This can be a great way to boost your overall return so keep an eye out before choosing which bookie to go with. It may be the case a certain bookmakers prices are lower for your selections but when the bonus is applied the overall return is higher.


The Accumulator

The betting term accumulator, or “acca” is used for all bets with 3 or more selections. The same conditions as doubles and trebles apply for an accumulator so all legs must win to be paid out.

Most bookmakers limit the number of legs allowed in an accumulator to 20 and often have a specific name for the bet depending on how many legs it contains. For example an acca with four legs is called a 4-fold,  a bet with 5 legs is a 5-fold and so on.

How to calculate: You put €5 on Barcelona at 1.2, Atletico at 1.57, Sevilla at 2.2 and Real Betis at 2.75 all to win their games. All legs win.

Stake x (Odds x Odds x Odds x Odds) = Return

€5 @ 1.2 & 1.57 & 2.2 & 2.75 = € 56.99 (€51.99 Profit plus your winning stake of €5 returned)

SRD Tip:  Take advantage of ACCA Insurance.

Acca insurance is a common concession that many bookmakers offer. Usually this insurance is free and your stake will be returned if one (and only one) of your selections fail to win.
