Underdog Promo Code Details for Tuesday's Games

The Underdog promo code COVERS unlocks a substantial welcome bonus for new fantasy sports players. After creating an account and making an initial $5 entry on any of Tuesday's games, users automatically receive $50 in fantasy bonus entries within 72 hours. This 10-to-1 bonus ratio provides significant value for exploring Underdog's daily fantasy contests across MLB, NBA, and NHL action.

The bonus entries come with straightforward terms: a 1x wagering requirement must be completed within 14 days, and the bonus funds expire after 60 days if unused. For example, if you enter a $5 NBA contest featuring the Cavaliers vs. the Lakers and your lineup finishes in the money, your winnings are immediately available for withdrawal after account verification. Even if your initial entry doesn't cash, you still receive the full $50 bonus to use on future contests like the high-stakes Red Wings vs. Penguins NHL matchup or any of the 14 MLB games on the slate.

The promotion is available in most states where Underdog operates, excluding New Jersey, New York, Maryland, Ohio, Michigan, and Pennsylvania. Players must be at least 18 years old (19+ in Alabama and Nebraska, 21+ in Arizona, Massachusetts, and Virginia) to participate. Compare this offer with other best prediction market promos to ensure you're maximizing your fantasy sports value.
