Underdog promo code delivers $50 bonus for 76ers vs Celtics

The Underdog promo code COVERS unlocks a substantial welcome bonus for new users looking to make predictions on the Eastern Conference playoff series between Philadelphia and Boston. After placing an initial $5 entry, users receive $50 in fantasy bonus entries within 72 hours. This bonus applies to daily fantasy sports contests, making it perfect for the high-stakes playoff atmosphere where Joel Embiid's health could dramatically impact the series outcome.

The bonus entries come with straightforward terms: a 1x wagering requirement that must be completed within 14 days, and the bonus must be used within 60 days or it expires. For example, if you create a lineup predicting Jayson Tatum to score over 25 points and the Celtics to win, and your prediction hits, any winnings can be withdrawn after account verification. If your initial prediction doesn't connect, you still have the $50 in bonus entries to continue making predictions on the remaining playoff games.

The offer is restricted in New Jersey, New York, Maryland, Ohio, Michigan and Pennsylvania, and users must be at least 18 years old in most states. Account verification is required before withdrawing any winnings. For those interested in comparing options, check out the best prediction market promos available across different platforms.
