What is an Acca? | Accumulator Betting Guide

Looking for more information on how accumulators work?

You’ve come to the right place.

In this guide, we’ll explore how accas work, different types of accumulator bet, and what you need to consider when placing an accumulator.

Let’s get started…

Acca Betting

Accumulator Bets – An Introduction

In simple terms, an Accumulator (or Acca), consists of a bet containing multiple selections, combined into a single wager.

Accumulators remain one of the most popular ways to bet, as they present an opportunity for a significant return from even a relatively small stake. However, all selections must win to guarantee a win from an accumulator bet.

With Marathonbet, you can place accumulator bets on a wide range of events, but football and horse racing tend to be the most popular sports for regular acca betting.

Let’s look at a working example of how you might place a football acca.

How do accumulators work?

Consider this scenario.

It’s a busy Sunday of Premier League football, with four back-to-back games.

Each game involves a traditional ‘top four’ side playing at home:

Liverpool vs West Brom
Man City vs Sheffield Utd
Chelsea vs Brighton
Man Utd vs Fulham

The four home sides are priced up to win as follows:

Liverpool – 1/5
Man City – 2/9
Chelsea – 1/3
Man Utd – 2/7

Now, on paper, all the home sides would be expected to claim a win, and that would be reflected in the matchday betting, where all four teams would be short-price favourites.

That means you would receive a modest return from a single bet on one of those four sides winning, given the high likelihood of that one result occurring.

For instance, if you were to place a single £10 bet on Liverpool to beat West Brom at 1/5, you would receive a return of £12.00.

However, if you were to add all four home selections to your betting slip – Liverpool (1/5), Man City (2/9), Chelsea (1/3) and Man Utd (2/7), and place a £10 accumulator instead, your return would jump considerably to £25.14.


Football doesn’t always follow the script. It’s what keeps fans coming back for more week after week.

Therefore, an acca will reward for you for taking the extra risk of adding multiple selections to your betting slip, as the more legs you add to your acca, the higher the chance at least one result will fail to land in your favour.

By relying on all four results outlined above to unfold, you are naturally increasing the risk the bet will not pay out compared to betting on just a single match outcome.

That’s why you’ll find the more selections you add to the acca, the higher the return you’ll get from your initial stake.

It’s always important to bear in mind that ALL selections must come in to guarantee a return – unless some form of Acca Insurance is offered prior to placing the bet. Acca Insurance works exactly as you might expect. In essence, you’ll be insured against one selection letting you down, provided the rest of your selections win. 

Acca Bets | Types of Accumulator Bet

In this guide, we’ve looked at a theoretical four-leg acca. These are also known as four-fold accas, with the acca name changing for every subsequent selection you add to the betting slip.

Common acca types include:

  • Four-Fold Accumulator bets (accas with four legs/selections)
  • Five-Fold Accumulator bets (accas with five legs/selections)
  • Six-Fold Accumulator bets (accas with six legs/selections)
  • Seven-Fold Accumulator bets (accas with seven legs/selections)
  • Eight-Fold Accumulator bets (accas with eight legs/selections)

With these accas, all legs must be successful to ensure a return.

How do Each-Way Accumulators Work?

Another popular type of acca, especially on horse racing, is the each-way accumulator.

These involve placing a bet with two stakes, one on all selections to win and one on all selections to be placed. These bets maximise your chances of guaranteeing a return, but the bet will cost twice as much compared to placing a regular accumulator.

Naturally, the place part of the accumulator will pay out less than a successful winning accumulator and is dependent on the place terms on each event within it.

If you mix an each-way accumulator with some selections on which there is no each-way betting available, such as a football team, those legs must win to count as successful in the place part of the accumulator.

Doubles, Trebles and Other Types of Accumulator

However, you can also pursue smaller accumulator bets – most notably double bets (two selections) and treble bets (three selections), while more accomplished bettors may wish to pursue Trixie or Yankee bets.
