A straight-line accumulator is a series of bets that must all be deemed successful in order to pay out to the punter.
Any single losing bet within the straight-line accumulator will mean the whole bet is judged to have lost even if four out of five results go in favour of the punter.
A straight-line accumulator is the most simple and popular form of accumulator betting as it is a way of generating much larger odds as multiple single bets need to win.
However, because a series of bets need to be successful in order to win the bet, the likelihood of this occurring is reduced, hence the better odds.
Straight-line accumulators are often referred to as accas but other forms include permutation bets, with both forms often the subject of special boost offerings from bookmakers.
How is Straight Line Accumulator used in Sports Betting?
An example of placing a straight-line accumulator would be to make a bet on the outcome of four Premier League football matches (win, lose or draw) and place all four bets in an accumulator in one bet.
Each bet would add to the overall prize pot, so you would get a set accumulated price for all four matches.
If any result were not to match, then the rest of the results would be voided and the bet deemed closed as a losing bet. However, if all four were to come in, then the odds will be far greater than having just placed single bets on the individual matches.
Did you know…
In 2009, a British bookmaker refused to pay out a whopping £7.1 million to a punter after his two-fold accumulator came in because the company said the bet should never have been allowed to be placed.
Remarkably, the accumulator bets were on nothing to do with sport, but one two postcodes where it would snow on Christmas Day.
