# Accumulator Bet | What’s An Acca Bet? How Does It Work?

An accumulator combines multiple selections into a single bet, with winnings rolled over to the next selection.

## What Is An Accumulator?

An accumulator bet, also known as an “acca” (or “parlay” in the USA) is similar to a treble bet in that it combines multiple selections into a single wager. However, accumulators can include any number of selections, not just three. The more selections included in the accumulator, the higher the potential payout, but the harder it becomes to win the bet.

To place an accumulator bet, the bettor selects multiple events or games they want to bet on and places a wager on all of them. For example, in basketball, a bettor might place an accumulator bet on the winners of five separate games. All five teams would have to win their respective matches for the bettor to win the accumulator bet.

If one of the selections loses, the entire bet is lost. However, some bookmakers offer “accumulator insurance,” where the bettor receives a refund or a free bet if only one selection loses. This can be a way to minimise losses while still having the chance to win big with multiple selections.

Accumulator bets are especially popular in sports such as football or horse racing, where there are often several matches or races taking place at the same time. Bettors can combine their selections from different matches or races to create an accumulator bet that covers multiple events.

It’s important to note that accumulator bets are much riskier than single bets or even treble bets because of the increased number of selections involved. However, there are significant payouts if all selections win.

### Example

Let’s say you place a £10 accumulator bet on five horse races with odds of 2.0, 3.0, 4.0, 5.0, and 6.0.

• If all five horses win their respective races, the total return will be £7,200 (£10 x 2.0 x 3.0 x 4.0 x 5.0 x 6.0), with £7,190 profit.
• If any horse loses, the entire bet is lost.
• If one race is canceled or declared void, the bettor will usually receive a payout based on the odds of the remaining selections.

Another way of looking at it is that the winnings from the first bet (£20) are rolled onto the second bet at 3.0, then those winnings (£60) are rolled onto the third bet at 4.0, and so on until the fifth bet at 6.0.

## What To Look For In An Accumulator

When placing an accumulator bet, there are several things to consider to increase the chances of a successful outcome:

### Value Odds

Look for selections that are undervalued by the bookmaker. This means that the odds assigned to the selections are higher than they should be, giving you a better chance to win and a higher potential payout.

### Number of Selections

Consider the number of selections you want to include in your accumulator. Remember that the more selections you include, the higher the potential payout, but the harder it becomes to win the bet.

### Insurance & Cashout

Accumulators are longshots. So consider using accumulator insurance or cash-out options to minimise potential losses.

Some bookmakers offer accumulator insurance, where the bettor receives a refund or a free bet if only one selection loses.

Cash-out options allow the bettor to settle the bet early, potentially securing a profit or minimising losses.
