Underdog Fantasy March Madness Contests

Underdog Fantasy doesn’t currently have any March Madness promotions yet, but this page will be updated with any profit boosts, free-to-play contests, or any special offers for the NCAA tournament.

When it comes time to bet on March Madness, Underdog Fantasy features two main ways for players to place their bets.

First, there is Battle Royales, where players draft their teams in a snake draft and compete against the rest of the entrants. The teams with the most points will win the top prizes available for each Battle Royale!

The other way bettors can get in on the fun of March Madness is through Pick’ems.

Players can build their own parlays by selecting Over or Under on up to five specific player props. The entry fee multiplier becomes higher with the more props you select.
