Margin betting allows you to select a margin of points a team can win by. A winning range is usually offered. I.e. Team A by 1 to 12 points, the winning margin must fall in this range for your bet to win.
In such a bet, the player will receive a win if the match ends with the victory of one of the teams: either Team 1 or Team 2 (i.e., there will be no draw). At the same time, it does not matter who will be the loser or with what score will win - the main thing is that the referee's protocol does not record a draw.
