What is Accumulator?
UK term for a parlay — a multi-leg bet requiring all selections to win.
Definition
Accumulator ('acca') is the British name for a parlay. Mechanically identical: 2+ legs, multiplied odds, lose if any leg loses. UK and Irish bookmakers heavily promote acca insurance (refund as free bet if one leg loses) and acca boosts (+5% to +100% on payout based on legs). These promos can shift the EV math but watch the wagering requirements on the refunded free bets.
Example
5-fold acca at 1.50 / 2.00 / 1.80 / 2.20 / 1.65 = decimal odds 19.6. £10 returns £196 if all five win.
