Underdog Promo Code COVERS Delivers $50 Spurs vs Heat Bonus

The Underdog promo code COVERS unlocks a generous welcome offer that transforms a modest $5 entry into $50 worth of fantasy bonus entries. This promotion applies perfectly to Monday's Spurs-Heat matchup, where Wembanyama's dominant season and Miami's injury concerns create compelling fantasy scenarios. New users must be 18 or older (with age restrictions varying by state) and located in eligible jurisdictions to participate.

The bonus structure works straightforwardly: after placing your initial $5 entry on players like Wembanyama or Tyler Herro, Underdog automatically credits your account with $50 in fantasy bonus entries within 72 hours. These bonus entries carry a 1x wagering requirement that must be completed within 14 days of receipt. For example, if you create a fantasy lineup featuring Wembanyama's points and Bam Adebayo's rebounds and your entry wins, you keep all winnings while working toward the wagering requirement.

The bonus entries expire after 60 days if unused, and account verification is required before withdrawing any winnings. This offer excludes residents of New Jersey, New York, Maryland, Ohio, Michigan, and Pennsylvania. Compare this generous welcome bonus with other best prediction market promos available today.
