How to Use Your Underdog College Basketball Promo Tonight
- Darryn Peterson (Kansas) vs. St. John’s – O/U 21.5 Points
- Ja’Kobi Gillespie (Tennessee) vs. Virginia – O/U 18.5 Points
- Brayden Burries (Arizona) vs. Utah State – O/U 16.5 Points
- Zuby Ejiofor (St. John’s) vs. Kansas – O/U 16.5 Points
- Mason Falslev (Utah State) vs. Arizona – O/U 14.5 Points
If we are looking to key in on the premier offensive talents tonight, Kansas freshman Darryn Peterson is an absolute must-watch. His 21.5-point morning line shows Underdog fully expects his heavy scoring to continue. But St. John’s has plenty of firepower to counter in the paint with Big East Player of the Year Zuby Ejiofor.
Over in Philadelphia at the Xfinity Mobile Arena, Tennessee’s Ja’Kobi Gillespie is a massive focal point for my own entries. Coming off an explosive 29-point, 9-assist game, Gillespie faces a Virginia defense desperate to slow him down. Oddsmakers have set his total at 18.5 points, which feels like a prime spot to target.
Finally, the Arizona vs. Utah State clash is going to be an offensive showcase. Arizona freshman Brayden Burries (O/U 16.5) is riding high after an 18-point outing where he shot a blazing 80% from beyond the arc. On the flip side, Mountain West Player of the Year Mason Falslev anchors Utah State’s offense.
How to Activate Your Underdog Promo Code
Ready to get in the trenches with us? Activating your bonus entries is a breeze. Just click here and follow these simple steps:
- Register Your Account: Create a new account using your standard personal information. Remember, you must be a new user and meet all local age and region requirements to play.
- Use the Code: You must enter promo code BROAD during the sign-up process to successfully lock in the offer.
- Make a Qualifying Deposit: Fund your account by depositing at least $5 using one of the available secure payment methods.
- Play Your First Entry: Submit a $5 entry on the college basketball slate to officially activate your $50 in bonus entries.
When I’m putting my entries together, I love that Underdog gives us two distinct ways to build our slips:
- Standard Entry: Combine 2+ picks for the largest possible payout. For this to hit, every single leg of your entry must be correct. It’s high risk, but there’s nothing better than cashing a perfect ticket.
- Flex Entry: Combine 3+ picks and choose the “Flex” option. While your maximum payout drops slightly, this strategy gives us a safety net. You can still receive some winnings even if one of your legs falls short.
