Accumulator bet (acca, parlay)

What is an accumulator bet?

An accumulator bet, also known as an acca or parlay, is a type of wager that combines multiple selections into a single bet. Instead of placing separate bets on each outcome, you group them together for a higher potential reward.

For the accumulator to win, every selection — often called a “leg” — must be correct. The odds for each selection multiply together, which can lead to much larger payouts than single bets. However, if just one selection loses, the entire bet loses.

Why use accumulator bets?

Accumulator bets attract players who want to maximize their potential returns with a relatively small stake. They are especially popular in sports betting, where combining several games or outcomes into one bet can create exciting opportunities for high payouts.

How does an accumulator bet work?

Here’s how accumulator bets function step by step:

  1. Choose your selections: Pick multiple outcomes from different events or markets.
  2. Combine them into one bet: Add each selection to your accumulator. Most operators allow you to combine events from various sports or leagues.
  3. Set your stake: Decide how much you want to wager.
  4. Watch every leg: All selections must win for your accumulator to pay out. If any selection loses, the entire bet loses.
  5. Calculate your potential winnings: The odds for each selection multiply together, creating a much higher total odds value than placing single bets.

Example:
You combine four football matches into an accumulator. The odds for each match are 2.00, 1.80, 1.90, and 2.10. The total accumulator odds are:
2.00 × 1.80 × 1.90 × 2.10 = 14.364
If you bet $10, your potential payout is $143.64.

Types of accumulator bets

Accumulator bets come in several forms, depending on how many selections you include:

  • Double: 2 selections
  • Treble: 3 selections
  • Four-fold: 4 selections
  • Five-fold and beyond: 5 or more selections

Some operators also offer special accumulator features, such as “each way” accumulators or systems that let you win even if some selections lose.

Advantages of accumulator bets

  • Higher potential payouts: Multiplying odds leads to much larger potential returns.
  • Excitement and engagement: Combining multiple events creates a thrilling betting experience.
  • Flexibility: You can include selections from various sports and markets.

Risks and considerations

  • All selections must win: If any single selection loses, the entire bet loses.
  • Higher risk: The more selections you add, the lower your chance of winning.
  • No partial payouts: Unlike some other bet types, accumulator bets do not pay out if only some selections win.

Best practices for accumulator betting

  • Research your selections: Make informed choices based on statistics, form, and expert analysis.
  • Limit the number of legs: While more legs mean higher odds, they also increase risk.
  • Set a budget: Stick to a betting budget to avoid chasing losses.
  • Use accumulator insurance: Some operators offer bonuses or refunds if only one selection loses.

Case study: Accumulator bet in action

A bettor combines three football matches into an accumulator. The odds for each match are 2.00, 1.80, and 1.90. The total accumulator odds are 6.84. With a $20 stake, the potential payout is $136.80. All three selections win, and the bettor collects the full payout.

If just one selection loses, the entire bet loses, and the stake is lost.
