Draw no bet (DNB) is a betting option offered by many bookmakers that allows you to gain profit if you guess the winner of the match but you get back your stake if the score is a draw. This privilege is of course at the price of reduced odds for the team to win the game. Even if your bookmaker does not offer this option, you can still place this type of bet by using this calculator. It estimates the proportion into which you have to distribute your total stake between the two bets (for a victory of one of the teams and for a draw) so that in case the score is a draw your net financial result is zero.
You can also use the calculator to check if your bookmaker offers you fair odds for DNB and if not construct your own combination. You can also play DNB placing the two bets at different bookmakers taking advantage of the higher odds they offer for different outcomes.
