Cost of duet bets

A duet bet requires you to select two of the first three horses in a race. It is a pari-mutuel bet type only offered by the TAB. The cost of duet bets is equal to the number of combinations of the bet. For example, if four horses are selected 1, 2, 3, 4, there are six possible combinations:

  • 1 and 2
  • 1 and 3
  • 1 and 4
  • 2 and 3
  • 2 and 4
  • 3 and 4

Calculating duet bets manually can be time consuming, so it’s best to use our duet bet calculator to save time and ensure accuracy.
