As it is most popular in the UK, most darts betting odds will be displayed in fractional format. If you’re betting on an underdog, the number on the right of the odds will be the amount you stake to win the number on the left. E.g 2/1 – if you bet 1, you can win 2. If you’re betting on a favourite it’s reversed e.g 1/3 – if you bet 3, you can win 1.
