Treble

A "Treble" is a multiple bet consisting of three selections, all of which must win to gain a return. The treble is a bet where three selections are made and the returns from the first are rolled over to the second, then the returns from the second rolled over to the third. Larger returns can be achieved using this bet at the expense of increased risk as all it takes is one losing selection for the bet to return nothing. Similar to the accumulator and double, only varying in their number of selections, a double having 2 and an accumulator having 4 or more. Popular in all sports especially horse racing, all bets in a treble must be on separate events.
