An acca bet (short for accumulator) is a single wager that strings together multiple selections into one bet. The winnings from each leg roll onto the next bet.
So how do football accumulator bets work in practice? Every betting market you add for a game (match result, total, O/U, BTTS) must win for the bet to pay out. One wrong result and the entire bet loses. Doesn’t matter if you correctly called nine results out of ten.
In exchange for taking on that risk, the odds of every leg get multiplied together, which is why modest stakes can snowball into a large payout with football accumulator betting .
It’s one of the most popular ways to bet on football (also the most misunderstood). A lot of punters place their wager without really knowing what an acca bet is. Below, we break down what is a football acca, how the odds and returns are worked out, the different types of accumulator you can place, and how they stack up against a straightforward single bet.
What Is an Acca Bet?
This is a bet that links two or more selections usually, though not always, from different football matches into a single betslip. So, instead of placing three separate bets on three different games on the same day, you combine all these bets into one football accumulator.
The bookmaker then multiplies the odds of each selection together to produce one combined price for the whole thing.
The rule that defines every acca is that all legs must win, regardless of size. There’s no partial credit.
For example, you might place an accumulator bet on three matches:
- Team A vs Team B – Home win
- Team C vs Team D – Draw
- Team E vs Team F – Away win
If all three results happen as predicted, your acca bet wins. However, if even one selection fails, the entire bet is lost.
How Do Football Accumulator Bets Work?
UK sportsbooks use fractional odds, where the denominator indicates the bet amount and the numerator shows the expected return. Once you open 7bet’s football betting page, you’ll see several matches available for betting.
Let’s say you bet on three matches:
- Leg 1: Team A wins with odds of 1/1
- Leg 2: Team B wins with odds of 2/1
- Leg 3: Team C wins with odds of 1/2
Odds are multiplied in football accumulator bets. However, combining fractional odds isn’t simple because they represent profit relative to a stake rather than total return. The trick is to add 1 to each fraction, multiply those together, then take 1 back at the end. You don’t have to worry about the calculations as they are done automatically in the betslip. But it’s helpful to understand why the odds change in acca bets.
- Step 1: Add 1 and convert the above odds to 2/1, 3/1, and 3/2.
- Step 2: Multiply them together. 2/1 x 3/1 x 3/2 = 18/2 = 9/1
- Step 3: Subtract 1 to get the final odds. 9/1 − 1/1 = 8/1
So this three-leg acca will give you combined odds of 8/1 overall.
An important part to note:
- Stake: Your betting amount, say £2.
- Total return: Your stake multiplied by the odds (8×2), plus your original stake returned. So, your total return on a £2 bet becomes 16 + 2 = £18.
- Profit: Your total return minus your stake, which is £18 − 2 = £16
These are important distinctions to understand so you know how much you stand to win once all legs are complete.
Types of Football Accumulator Bets
Not every accumulator has to be excessively big. There are several formats that balance payout size and the likelihood of actually winning:
Double
This is the smallest possible accumulator, made up of two selections. A double won’t produce an eye-catching return, but it comes with a big advantage: only two results need to go your way instead of five or six. It’s a far more realistic bet. If you are new to betting, consider a double before moving on to bigger accas.
Treble
This is a three-leg football accumulator bet. Three selections gives you a bigger payout than a double. Treble is also relatively low risk as the number of things that can go wrong is still low compared to traditional accas. It balances risk and reward.
Larger accumulators
Anything from four selections upward is a large accumulator bet. The potential returns climb steeply as you add more selections. However, with every additional leg, the overall win probability of the whole bet drops quite significantly. This is the bet that goes wrong most often, so new bettors should avoid it.
Trixie
A Trixie splits three selections into three doubles and one treble. The stake is split across each accumulator. A Trixie can return a profit even if one of your three selections loses, as the other two bets can still combine into a winning double. A Trixie costs more to place than a treble, because you have to fund four bets. But this bet gives you a bit of a safety net.
Patent
A Patent splits three selections across seven separate bets: three singles, three doubles, and one treble. Because singles are included, a Patent will return something even if only one of your three selections wins. That makes it the most forgiving combination bet in an accumulator. However, patents are the most expensive bets to place, since punters have to cover seven bets instead of one.
Football Accumulator vs Single Bet
A single bet is simple to follow as you need to make one selection at the given odds and wait for its outcome. Your stake rides only on that result. A football accumulator, on the other hand, links multiple selections together into one wager. The odds are multiplied and your potential return becomes much bigger.
So, which bet is better? The decision lies in your risk appetite. Here’s a quick guide for you to decide:
| Single Bet | Football Accumulator |
| Lower risk | Higher risk |
| Gives short odds, meaning your payout will be less. | Long odds, which can return a bigger profit. |
| Higher chance of success. | Low chance of success as multiple outcomes need to win. |
| Ideal for cautious and new bettors. | Ideal for seasoned bettors and those who follow football matches closely. |
| Suitable for small bankrolls. | Avoid this bet if you have a small bankroll as the risk is higher. |
What Happens If One Selection in an Acca Loses?
If a single selection in a standard accumulator loses, the entire bet loses with it. There’s no partial payout built into a traditional acca. Every leg must win for the bet to settle with a profit. If you understand how football accumulator bets work, then opt for a Trixie or a Patent. These bets split your wager across several smaller bets, like doubles, trebles, and singles as well (in Patent). You don’t have to rely on every single result going your way to get some money back.
Keep an eye out for acca insurance or money-back offers, which a lot of bookmakers run from time to time. These offers can be used if only one leg loses in your acca. Your stake is refunded, either as cash or as a free bet.
Understanding Football Accumulator Bets
An acca bet combines multiple football selections into a single wager. The odds of each leg are multiplied together to produce one combined price. That’s how football accumulator bets turn a small stake into a large return. However, it comes with a condition: every leg must win for the bet to pay out. Trixies and Patents are low-risk accas that allow some flexibility.
Now that you know what’s an acca bet, it’s worth weighing the odds and the number of legs against how comfortable you are with the risk. You can browse the full range of markets on the football betting page and see how the odds stack up in accas.
