Accumulator

Also called: Acca, Parlay, Multiple

A single bet combining several selections where every leg must win.

The legs' decimal odds are multiplied together, so the potential return climbs steeply — and so does the chance of losing everything, because one failed leg loses the whole stake.

Accumulator mathematics

Legs2.10 × 1.50 × 2.00
Combined odds6.30
Stake£10.00
Total return£63.00
Profit£53.00
Combined implied probability15.9%

Note: the same three selections as separate single bets would each settle independently — the accumulator trades a much lower chance of any return for a much larger one.
