There are numerous betting options available during the March Madness tournament.

With the tournament known for its thrilling finishes and buzzer-beaters, there are also novelty props that add to the excitement throughout the weeks. Additionally, you can participate in the futures market by predicting the overall winner of the tournament rather than placing a simple moneyline bet.
