NCAAB Player Picks for the Underdog Promo Code

If you are looking for the best ways to put your Underdog promo to work, here are several players in action on Thursday afternoon:

Cameron Boozer (Duke Blue Devils) vs. Siena Saints

• Points Line: 22.5

Bruce Thornton (Ohio State Buckeyes) vs. TCU Horned Frogs

• Points Line: 19.5

Ryan Conwell (Louisville Cardinals) vs. South Florida Bulls

• Points Line: 19.5

John Blackwell (Wisconsin Badgers) vs. High Point Panthers

• Points Line: 19.5

Pryce Sandfort (Nebraska Cornhuskers) vs. Troy Trojans

• Points Line: 18.5

When I’m putting together my entries, I always look for guys carrying the narrative and the offensive load. Duke freshman phenom Cameron Boozer is the ultimate key for the Blue Devils with a massive 22.5-point projection against the Siena Saints.

Meanwhile, Ohio State’s Bruce Thornton draws a 19.5-point line against the TCU Horned Frogs. Thornton is the heart and soul of this Buckeyes team, sticking around through the lean years to become their all-time leading scorer.

Up in Buffalo, we’ve got a fantastic storyline with Louisville’s Ryan Conwell facing his former team, the South Florida Bulls. With teammate Mikel Brown Jr. sidelined by a back injury, the Cardinals will lean heavily on Conwell to clear his 19.5-point mark.

Out west, Wisconsin’s John Blackwell shares that same 19.5-point tier. He just dropped a career-high 34 points and is playing incredible basketball alongside the rest of the Badgers’ backcourt. Finally, Pryce Sandfort brings an 18.5-point line into his matchup as Nebraska looks to secure its first-ever NCAA Tournament victory against Troy. These are the kinds of high-stakes matchups where we can find a serious edge.

How to Use the Underdog Promo Code

Unlocking your bonus entries is a breeze, and I’m going to walk you through exactly how I set it up. If you are a new user and meet the necessary age and region requirements, click here and follow these simple steps:

1. Register Your Account: Create a new profile by providing your standard personal information.
2. Enter the Promo Code: You absolutely must use promo code RUSSELL during the sign-up process to qualify for the offer.
3. Make a Secure Deposit: Fund your account by depositing at least $5 using one of the platform’s secure payment methods.
4. Place Your First Entry: Play a minimum $5 entry to officially activate your $50 in bonus entries.

Once your account is funded, it’s time to strategize. We have two main ways to attack the board. A Standard entry consisting of 2+ picks is like your traditional parlay—it triggers the largest potential payout, but keep in mind that all your legs must hit in order to win.

If you want a little insurance, I highly recommend you Flex an entry with 3+ picks. Much like boxing a trifecta, a flex entry gives you some margin for error, meaning you can still cash a ticket and receive some winnings even if one of your selected legs is incorrect.
