Accumulator (general terms )



A bet in which a single stake is used to generate two or more bets in succession.
The punter makes a series of selections each from a different race or event.
Every time a selection wins, the stake plus winnings is put onto the next selection.
If any selection loses, the whole bet is a loser. (Accumulators are also known as doubles, trebles,
fourfolds, fivefolds, sixfolds, etc., depending on the number of selections.)
