What is a football Acca, or sports accumulator?

A football or sports accumulator is a bet of multiple selections that combines four or more picks into a single bet that wins when all selections come in.

Accumulator Bet Slip
The benefit of an accumulator is that winnings are much higher due to the increased risk and combined odds, they can be difficult to land as usually the more choices the more chance of an upset.

Non-Runner Acca

If one selection doesn’t play or you pick a non-running horse the accumulator is reduced i.e. a six-fold would become a five-fold.

Accumulators are available on all sports, but, bookmakers vary in their rules on combining selections from more than one to create a single bet. Selections from the same event cannot be combined into a single accumulator, this is to deter anyone from trying to place several bets on the same selection.

There is also the option to place permutations on accas, e.g 4 from 6 or 5 from 6 and so on. Please see the types of bets below.

Another way is to find a bookmaker who offers acca insurance

The favoured approach is to place fancied choices in positions 2, 3, 4 and 5, leaving 1 and 6 for the least favourite as these are not included in the Yankee.

What is a Flag bet?
