Warriors vs Celtics Underdog Promo Code Details
The Underdog promo code COVERS delivers substantial value for new users looking to engage with fantasy sports. After placing your initial $5 entry on picks related to the Warriors-Celtics game, you'll receive $50 in fantasy bonus entries within 72 hours. This 10-to-1 return makes it an attractive option for testing different strategies on Wednesday's matchup.
The bonus comes with specific terms that users should understand before claiming. You must be at least 18 years old (19+ in Alabama and Nebraska, 21+ in Arizona, Massachusetts and Virginia) and located in a state where Underdog Fantasy operates legally. The offer is not available in New Jersey, New York, Maryland, Ohio, Michigan and Pennsylvania. Your bonus entries carry a 1x wagering requirement that must be completed within 14 days, and the bonus expires after 60 days if unused.
For example, if you place a $5 entry on Jayson Tatum to score over 25.5 points and it wins, you keep your winnings plus gain access to your $50 bonus. If your initial pick loses, you still receive the full bonus amount to use on future entries. Account verification is required before withdrawing any winnings or bonus funds.
