Multiple bets may also be referred to as accumulation bets or accumulators.
When you are making a multiple bet, you will be attempting to correctly predict the outcome of more than one race in a single bookmaker bet.
For example, you might make a bet involving horses in the first three races of a meeting. If you made a multiple bet, this would be known as a treble bet (a double bet involves just two races). Your multiple bet would only be successful if all three horses won their races. Your winnings from the first fixture are used as your stake on the second race. The money won on the second fixture goes onto the third race.
In case of a win/place multiple, calculation of winnings will be performed on a bet type on bet type basis, which is, win on win and place on place.
This means that if you made a successful multiple win bet on three races, where the odds on your runner were 2.00 in each fixture, your winnings would be calculated as follows;
2.00 x 2.00 x 2.00 = 8.00
This means that you would be paid out at odds of 8.00.
Should a selection become a non-runner, this runner shall be settled as a winner at odds of 1.00. It results in your stake being assigned to the next selection in the multiple. This only applies in races where the Rule 4 is in place, or if the bet has been placed as a bookmaker bet. Otherwise it will be settled as a losing selection. The same applies in the event of race cancellation.
