Underdog Promo Code Delivers $50 March Madness Bonus
The Underdog promo code COVERS transforms a modest $5 entry into $50 in fantasy bonus entries, creating substantial value for Sunday's March Madness slate. New users must place their initial $5 entry on any fantasy contest, triggering the automatic bonus credit within 72 hours. This welcome offer applies perfectly to Sunday's high-profile matchups, where star players like Purdue's Braden Smith and Kentucky's Otega Oweh provide excellent fantasy targets.
The bonus carries a 1x wagering requirement that must be completed within 14 days, while the $50 credit expires after 60 days if unused. Account verification is mandatory before withdrawing any winnings or bonus funds. Key terms include:
- Minimum age requirements vary by state (18+ in most locations, 21+ in Arizona, Massachusetts and Virginia)
- Offer unavailable in New Jersey, New York, Maryland, Ohio, Michigan and Pennsylvania
- Bonus entries automatically credited within 72 hours of qualifying entry
For example, if you create a fantasy lineup featuring Miami's Malik Reneau and Iowa State's balanced scoring attack and your picks hit, you keep all winnings plus have $50 in bonus entries for future contests. Even if your initial selections fall short, the bonus entries provide additional opportunities across upcoming tournament games.
Compare this offer alongside other best prediction market promos to maximize your March Madness value.
