Accumulator mechanics
The combined decimal price is produced by multiplying the price of each leg. One losing leg normally loses the full accumulator; a void leg is usually removed and the price recalculated under house rules.
Accumulator versus Bet Builder
888sport's Bet Builder is documented. A standard accumulator combines outcomes from different events; a Bet Builder combines compatible outcomes from one event.
