Underdog Promo Code COVERS Delivers $75 Fantasy Bonus

The Underdog promo code COVERS transforms your first $5 fantasy entry into $75 worth of bonus entries, creating excellent value for the Celtics vs Suns showdown. This welcome offer applies to both draft contests and pick'em games, allowing you to predict whether players like Jaylen Brown will exceed their projected totals or build a complete fantasy roster around the game's top performers. The bonus entries arrive within 72 hours of your qualifying play and come with a 1x wagering requirement that must be completed within 14 days.

Key terms for this promotion include:

  • Available to new users 19 years or older (21+ in Virginia)
  • Bonus expires after 60 days if unused
  • Account verification required before withdrawals
  • Not available in Maryland, Michigan, Pennsylvania, or Ohio

For example, if you create a pick'em entry predicting Brown will score over his 29.2-point average against Phoenix's depleted defense and your entry wins, you'll receive both your original winnings plus access to the $75 in bonus entries. Even if your initial play doesn't hit, you still receive the full bonus amount to use on future contests.
