March Madness Underdog Promo Code Details
The Underdog promo code COVERS delivers $50 in fantasy bonus entries when new users make their first $5 entry into any contest. This welcome bonus applies perfectly to Thursday's March Madness action, which features compelling matchups like Duke versus Siena, Texas against BYU, and Arkansas facing Hawaii. New users must be at least 18 years old (19+ in Alabama and Nebraska, 21+ in Arizona, Massachusetts and Virginia) and located in an eligible state to qualify for this promotion.
The bonus entries arrive automatically within 72 hours of your qualifying entry and come with straightforward terms. You'll need to use the bonus within 60 days of receipt, and there's a 1x wagering requirement that must be completed within 14 days. For example, if you enter a March Madness contest featuring the Duke-Siena game and your picks perform well, any winnings can be withdrawn after account verification. If your initial picks don't hit, you still have $50 in bonus entries to use on upcoming tournament games.
This offer is not available in New Jersey, New York, Maryland, Ohio, Michigan and Pennsylvania. Account verification is required before withdrawing any winnings or bonus funds.
