Football accumulators, often shortened to accas and sometimes known as multiples, are a way for players to bet on a range of matches at once.
To get paid out from an accumulator, each selection – or leg – must win, with just one losing choice seeing the bet deemed as a loser.
By design such wagers are risky but they can often have large potential pay-offs and require only a single stake, making them a regular choice for recreational bettors.
