New Underdog customers have an excellent opportunity to build their bankrolls right out of the gate. By registering and playing just $5 on your first entry, you will instantly get $50 in bonus entries added directly to your account. We’ve seen time and time again that securing a promotional bonus is one of the most effective ways to capture immediate value as you explore the board.

Keep in mind that this promotion is exclusively available to first-time players. To successfully claim your bonus entries, you must meet the minimum age requirements and be physically located in a participating state where Underdog operates. Be sure to verify your eligibility during the registration process so you do not miss out on this $50 reward.

How to Use Your Underdog NBA Bonus Tonight

  • Cade Cunningham, Detroit Pistons (vs. Cleveland Cavaliers): 28.5
  • Victor Wembanyama, San Antonio Spurs (vs. Minnesota Timberwolves): 27.5
  • Donovan Mitchell, Cleveland Cavaliers (at Detroit Pistons): 23.5
  • Anthony Edwards, Minnesota Timberwolves (at San Antonio Spurs): 18.5
  • James Harden, Cleveland Cavaliers (at Detroit Pistons): 18.5

The board is loaded with superstar talent tonight, making for some fascinating prop matchups where sharp players can extract real value. We put a lot of stock in situational matchups, and Cade Cunningham tops the list with a lofty 28.5-point line. He serves as the primary engine for Detroit, averaging an impressive 31.2 points per game in the postseason. Tonight, he tests a Cleveland defense giving up 110.2 points per contest and allowing opponents to shoot 35.9% from beyond the arc in their eight playoff games so far.

Over in San Antonio, Victor Wembanyama draws a 27.5-point total against the Timberwolves. The young star has averaged 19 points per game in the playoffs, and he will need to navigate a stingy Minnesota defense yielding only 106.7 points per playoff game. With Rudy Gobert and Naz Reid anchoring the frontcourt, fading elevated projections here might be a savvy move.

How to Activate the Underdog Promo Code SOUTH

Activating your bonus ahead of tonight’s Cavaliers vs. Pistons tip-off is a straightforward process. Follow these simple steps to claim your promotion and start building your entries:

  1. Register an Account: Download the app or visit the Underdog website to create your new account. You will need to provide standard personal information to verify your identity. Crucially, you must enter the promo code SOUTH during registration. Please note that you must be a new user and meet all regional and age requirements to be eligible.
  2. Make a Deposit: Once your account is verified, navigate to the banking section and deposit at least $5 using one of the available secure payment methods.
  3. Play Your First Entry: To officially trigger your $50 in bonus entries, you have to play a $5 entry. You can use this initial entry on tonight’s Cavaliers vs. Pistons game or any other available sporting event.

When you are ready to construct your card, Underdog offers two distinct ways to play:

  • Standard Entry: This approach requires 2+ picks and unlocks the largest potential payout multiplier. However, it is an all-or-nothing proposition—every leg in a standard entry must hit for you to win.
  • Flex Entry: Alternatively, you can flex an entry, which requires 3+ picks. While the overall payout multiplier is slightly reduced, a flex entry provides a built-in safety net, allowing you to still realize a return on your investment even if one of your longshot legs falls short.
