Acca Bet Explained
An acca, short for accumulator, is a single bet that links four or more selections, and every one of them has to win. The return from each selection is staked on the next, so the odds multiply together, and one losing selection loses the whole bet. Fortune Games takes no sports bets, so the examples on this page are bets placed with a bookmaker.

How an acca works
Each selection in an acca is called a leg. The stake goes on the first leg, and if it wins, the whole return becomes the stake on the second, and so on to the last. That is why the decimal odds multiply: the potential return is the stake times the odds of every leg. Say you put £5 on a fourfold with a bookmaker, with each leg at decimal odds of 2.00. If all four win, the return is £5 × 2 × 2 × 2 × 2, or £80. If any one of them loses, the bet returns nothing, however the other three finish.
Every leg you add multiplies the potential return again, and adds one more selection that has to win.
When a leg is made void
Sometimes a selection is cancelled before it can win or lose, and it is made void. A void leg doesn’t sink the acca: it is taken out, and the bet is settled on the legs that remain, at their combined odds. In the example above, a void leg would turn the fourfold into a treble at 2 × 2 × 2, so three winners would return £40 from the £5 stake.
Accas and full-cover bets
A full-cover bet splits the same selections into many smaller bets, so one loser doesn’t wipe out everything. A Yankee covers four selections with 11 bets, six doubles, four trebles and a fourfold, and needs two winners for any return. A Lucky 15 adds the four singles to make 15 bets, so a single winner can bring a return. On three selections, a Trixie is four bets and a Patent seven, singles included, while a Heinz is 57 bets on six selections.
Each of those bets carries its own stake, so they cost more than a single acca: a £1 Yankee costs £11 and a £1 Lucky 15 costs £15, where a £1 fourfold costs £1.
Frequently asked questions
What does acca mean in betting?
Acca is short for accumulator. Bookmakers name linked bets by size: two selections make a double and three a treble, and from four upwards the bet is an accumulator, called a fourfold, fivefold, sixfold and so on. In theory an accumulator can hold as many selections as you like.
What happens if you lose one bet in an accumulator?
The whole accumulator loses. A leg only passes a return on to the next if it wins, so one losing selection ends the bet, whichever leg it is and however the rest finish, and the stake is lost. That is where an acca differs from a full-cover bet, in which the doubles and trebles that don’t include the losing selection can still pay.
Can you place an each-way acca?
Yes. Each-way bets can be placed on multiples as well as on single selections. An each-way acca is two accas of the same stake, one needing every selection to win and one needing every selection to be placed, so it costs twice as much. The two halves are settled win to win and place to place, so a selection that is placed but doesn’t win loses the win half while the place half carries on.
