Claim the Underdog Promo Code Before UFC 331 Kicks Off
New users can unlock this offer through the Underdog promo code page, where entering COVERS during sign-up activates a 50% deposit match up to $1,000. The match applies once a qualifying deposit of at least $10 is made, and Underdog can take up to 72 hours to issue the bonus funds. Those funds arrive as bonus entries rather than withdrawable cash, so a playthrough requirement applies before any promotional balance becomes eligible for withdrawal.
- Minimum deposit: $10, with a maximum match of $1,000 on a $2,000 deposit
- Playthrough: 1x the deposit plus bonus amount within 14 days of the bonus posting
- Bonus entries: Cannot be applied to entries with a payout multiplier below 2x
- Unused bonus: Any unmet playthrough balance is forfeited once the 14-day window closes
Consider how this plays out around UFC 331. A bettor who deposits $100 receives a $50 match, creating a $150 balance that must be played through on eligible entries tied to the Van-Pantoja card before the 14-day window closes. If those entries win, the resulting balance can move toward becoming withdrawable once the playthrough is satisfied. If the entries lose, the funds used in that entry are gone, and the remaining balance still needs to satisfy the playthrough requirement within the deadline.
