Underdog Fantasy promo code delivers $75 bonus for Christmas basketball

The Underdog Fantasy promo code COVERS unlocks a substantial $75 bonus for new users who make their first $5 entry. This offer applies perfectly to the Christmas Day Cavaliers vs Knicks game, where you can build fantasy lineups featuring stars like Jalen Brunson and Karl Anthony-Towns. The bonus is credited to your account within 72 hours and comes with a 1x wagering requirement that must be fulfilled within 14 days.

Key terms for this welcome offer include age requirements of 19 years old in most states and 21 in Virginia. The bonus expires 60 days after it is unused, and account verification is required before any withdrawals can be made. This promotion is not available in Maryland, Michigan, Pennsylvania, and Ohio.

For example, if you enter a $5 Pick'em contest predicting whether Jalen Brunson will exceed his points projection against Cleveland and your picks hit, you would receive both your contest winnings plus the $75 bonus credit. Even if your Christmas Day predictions fall short, you still receive the full bonus amount to use on future contests.
