An accumulator is when you make more than four selections in the same bet.
You can make as many as you like, as long as it is above four. The more selections you make, the higher the odds of the bet will be.
Every selection will need to win for you to see a return, or place if your bet is an each way accumulator. If just one pf your selections fail, then you lose.
Like with a double or treble bet, the individual odds of each selection are combined to create a single bet.
You can use our free accumulator bet calculator below to determine what those odds will be, before you place your bet.
