Accumulator
The British/European term for a parlay, combining multiple selections into one bet.
An accumulator (or "acca") is the European term for what Americans call a parlay. It combines multiple match selections into a single bet, where all legs must win for the bet to pay out. Accumulators are extremely popular in soccer betting markets globally.
How Accumulators Work
Each selection's decimal odds multiply together. A 4-fold acca at odds of 2.0 × 1.8 × 2.5 × 1.6 = 14.4, so a $10 bet returns $144. One losing leg voids the entire ticket.
Each-Way Accumulators
In horse racing and golf, bettors often place each-way accumulators, combining both win and place bets across multiple selections. This provides partial returns if selections place rather than win.
Key Takeaways
- Accumulator = parlay in European betting terminology.
- All legs must win. One loss ends the bet.
- Very popular in European soccer markets.
Examples
