A multiple bet consisting of two selections, both of which must win to gain a return.
The double is a bet where two selections are made, and if the first wins, everything that would have been returned is then used as a stake for a second. This style of bet is popular because it creates the potential for larger returns but at the expense of increased risk as all it takes is one losing selection for the bet to return nothing. Similar to the treble and accumulator the only difference is a lower number of selections. Each way and to-place only options are also available at some bookmakers.
Popular in all sports, especially football and horse racing, all bets in a double must be on separate events.
Once familiar with the examples, use the double calculator to work out winnings quickly. The accumulator calculator can also be used to experiment with more than 2 selections.
