Underdog Promo Code Details for April 23 Sports Action

The Underdog promo code COVERS unlocks a substantial welcome bonus for new users looking to engage with Thursday's diverse sports offerings. After placing your initial $5 entry on any contest featuring games like the tied Knicks-Hawks series or the competitive Brewers-Tigers MLB matchup, you'll automatically receive $50 in fantasy bonus entries within 72 hours. This bonus carries a 1x wagering requirement that must be completed within 14 days, and the bonus funds expire after 60 days if unused.

The promotion applies to users who are 18 years or older (19+ in Alabama and Nebraska, 21+ in Arizona, Massachusetts and Virginia) and are located in eligible states. However, residents of New Jersey, New York, Maryland, Ohio, Michigan and Pennsylvania cannot access this offer. Account verification is required before withdrawing any winnings or bonus cash.

For example, if you enter a $5 contest featuring the Timberwolves-Nuggets playoff game and your picks perform well, any winnings from your initial entry are yours to keep, plus you'll have the $50 bonus to use on additional contests. Even if your first entry doesn't win, you still receive the full bonus amount to continue playing.

Compare this offer with other best prediction market promos to see how Underdog's welcome bonus stacks up in the daily fantasy sports landscape.
