Draw no bet (DNB) in rugby betting allows you to wager on a team to win, with the safety net that if the match ends in a draw, your stake is refunded. This eliminates the draw outcome, making it a two-way market. For example, if you bet on Team A to win against Team B and the match ends in a draw, you get your money back.
For visual examples, you can refer to betting sites that illustrate DNB markets, showing how the odds are presented and how the betting process works.
