Accumulator bets are extremely popular due to the big returns that a customer can enjoy from a small stake. Every week, customers manage to win large amounts from their accumulator bets by correctly predicting the outcome of football matches or horse races, although there is the option to place an accumulator on any number of sporting events.

Accumulators are also known as Accas and usually involve a customer combining at least four selections on their bet slips, with two selections usually being called a double and three selections being termed as a treble.
