World Baseball Classic and NCAA Tournament Underdog Promo Code Details
The Underdog promo code COVERS delivers exceptional value for new users looking to engage with this weekend's compelling sports action. After creating an account and placing your initial $5 entry on any contest, you'll automatically receive $50 in fantasy bonus entries within 72 hours. This promotion works perfectly for the current sports landscape, where conference tournament bubble teams are fighting for their tournament lives and World Baseball Classic powerhouses like Japan and the Dominican Republic are positioning for knockout round advancement.
The bonus structure includes several important terms to consider:
- Must be 18+ (19+ in AL, NE; 21+ in AZ, MA, VA) and located in eligible states
- Bonus entries carry a 1x wagering requirement within 14 days
- 60-day expiration period for unused bonus funds
- Account verification required before withdrawals
- Not available in NJ, NY, MD, OH, MI, and PA
For example, if you enter a $5 contest predicting whether a bubble team will advance in their conference tournament and win, your original entry pays out normally while your bonus entries provide additional opportunities. Even if your initial prediction doesn't hit, the $50 in bonus entries gives you multiple chances to capitalize on NBA games or World Baseball Classic matchups throughout the weekend.
Compare this offer with other best prediction market promos to see the competitive advantage.
