Another term for Accumulators. Multiple bets involve more than one selection. Double and
trebles are popular wagers for football match betting. A double is one bet involving two selections in
different events, both of which must be successful for the bet to win. The odds for a double are calculated
by multiplying together the separate odds for the two single bets. Accumulators contain 4 or more selections.
Often, the only limit to the number of selections included within an accumulator bet is the bookmaker's
maximum allowable payout on one bet.
