Parlay vs Acca — What is the Difference Between Parlay and Accumulator?

Parlay vs Acca bets

If you have enjoyed online sports betting before, you have probably noticed that most bookies allow you to put more than one bet on a single betting slip. You may have also noted that some sportsbooks call these multiple wagers accumulator bets, while others refer to them as parlay bets.

We are here to tell you that you shouldn’t get confused by these two separate terms, as they denote the exact same thing. However, the term “accumulator bet” (or “Acca,” for short) is preferred in the UK, whereas “parlay bet” is a common term used among North American bettors.

You may have also heard people mention double or treble to refer to betting slips that consist of two or three bets, but these can also be called accumulators. In fact, any betting slip that has more than one selection on it can be labelled as an accumulator or parlay, and you are allowed to place as many selections as the betting operator allows, which is usually up to 20. Some might also call this type of bet a combination bet.

So, now that we’ve gotten semantics out of the way, we can focus on explaining how accumulator or parlay bets work. Below, you will see some of the most common types of accumulator bets, after which we will list the best betting sites that allow this kind of betting.

Common Accumulator Bets

Accumulator bets can be placed on a wide variety of sporting events and betting markets. Many punters like placing accumulator bets on horse racing, as they can combine selections on multiple races. One of the most popular bets here is the each-way accumulator bet, where the horses need to either win or place for the bet to be successful. The winnings are then calculated by applying the each-way fraction on every selection.

1×2 football betting is another popular market for accumulators. Here, you simply need to predict the outcomes of several football games and put them on the same betting slip. Here is an example:

  • Liverpool vs Aston Villa (1 on odds of 1.30)
  • Manchester City vs Leicester (1 on odds of 1.45)
  • Crystal Palace vs Arsenal (2 on odds of 1.50)
  • Chelsea vs Manchester United (X on odds of 2.90)

If all matches finish as predicted, you will win at the odds of 8.20 (1.30 x 1.45 x 1.50 x 2.90), meaning that if you bet £10, you will end up winning £82.

In order for an Acca bet to be a winning one, each of your individual bets must be successful. Even if one selection is wrong, you will lose the entire bet. However, some bookies offer an early payout option before the last game finishes, whereas others compensate for your losses by giving you a percentage of potential winnings if you only miss by one leg.

You can place an accumulator bet on various sports, including cricket, rugby, snooker, tennis, basketball, and more. You can also mix multiple selections from different sports on the same betting slip. For example, you can put two tennis matches alongside three football games and a single horse race. As mentioned, the accumulator bet can have anywhere from 2 to 20 selections or more.

Almost every sports betting site accepts accumulator bets. If you want to find the best odds, a wide variety of betting markets, and fantastic sports betting bonuses, here are some of the bookies that you should consider.
