How to Use Your Underdog NBA Bonus Tonight

Much like analyzing a team facing a first-place schedule or evaluating the impact of a new offensive coordinator on the gridiron, finding value on the hardwood requires looking at situational context. If you are looking to take advantage of player projections, tonight’s slate features some lofty scoring expectations.

Here are the five players with the highest point lines for the night:

  • Jalen Brunson (New York Knicks vs. Philadelphia 76ers) — 27.5 Points
  • Victor Wembanyama (San Antonio Spurs vs. Minnesota Timberwolves) — 27.5 Points
  • Joel Embiid (Philadelphia 76ers at New York Knicks) — 26.5 Points
  • Tyrese Maxey (Philadelphia 76ers at New York Knicks) — 24.5 Points
  • Anthony Edwards (Minnesota Timberwolves at San Antonio Spurs) — 18.5 Points

We put a lot of stock in situational matchups when hunting for value. Jalen Brunson draws an appealing setup against the 76ers, who are surrendering 110.4 points per game this postseason. Averaging 27.6 points overall in the playoffs, Brunson remains the clear offensive engine for New York.

Tied for the highest total on the board, Victor Wembanyama is listed at 27.5 points despite averaging 19.0 points in the postseason and just 15.0 over his last five outings. He will face a Timberwolves defense holding opponents to 106.7 points per night, making his high total an intriguing line to evaluate if you want to fade consensus expectations.

Joel Embiid and Tyrese Maxey carry massive expectations as they go up against a stingy Knicks defense that restricts opponents to a mere 100.0 points per game. Embiid is currently posting 25.2 points, while Maxey is contributing 25.1 per contest. Given New York’s defensive success, clearing these point totals will be a significant test for the Sixers’ dynamic duo.

How to Sign Up With the Underdog Promo Code SOUTH

Getting started with Underdog and claiming your welcome bonus is quick and easy. Follow these steps to unlock your bonus entries:

  1. Sign Up: Create and register a new account on the Underdog app or website. You will be asked to provide standard personal information to verify your identity.
  2. Use the Code: Enter the promo code SOUTH during the registration process. This is required to ensure your account is linked to the promotional offer.
  3. Make a Deposit: Fund your new account by depositing at least $5 using one of Underdog’s secure payment methods.
  4. Play an Entry: Submit your first entry of $5 or more. Once placed, your account will be instantly credited with $50 in bonus entries.

Note: This offer is exclusively for new users who meet the minimum age and regional requirements for their respective states.

When building your entry, you will have two primary ways to play, and understanding these mechanics is crucial to managing risk:

  • Standard Entry: This requires selecting 2 or more picks. While a Standard entry triggers the largest potential payout multiplier, all of your selected legs must hit in order to win.
  • Flex Entry: This option requires 3 or more picks. It offers a slightly lower maximum payout than a Standard entry, but it provides a safety net—you can still receive a portion of your winnings even if one of your legs is incorrect, which is an ideal strategy when mixing in a longshot.
