Underdog Promo Code Details for $50 Bonus

The Underdog promo code unlocks a generous welcome bonus for new fantasy sports players. After creating your account and entering the code COVERS, you'll need to place an initial $5 entry to receive $50 in fantasy bonus entries within 72 hours. This promotion is perfect for Sunday's Tigers-Cardinals game, where Keider Montero will start in place of the injured Verlander against Kyle Leahy.

The bonus comes with specific terms you should understand. You must be 18 or older (19+ in certain states, 21+ in others) and located in an eligible state where Underdog operates. The offer is not available in New Jersey, New York, Maryland, Ohio, Michigan, or Pennsylvania. Your bonus entries carry a 1x wagering requirement that must be completed within 14 days, and you have 60 days to use the bonus before it expires.

For example, if you place a $5 entry on Tigers players to perform well in Sunday's game and win, you'll receive your winnings plus still have your $50 bonus to use on future contests. Even if your initial entry doesn't win, you still receive the full $50 bonus to continue playing.

Compare this offer with other best prediction market promos to see why Underdog stands out.
