If you are looking for a statistical edge on Underdog, Victor Wembanyama presents an intriguing case. Through six games in this series, he has racked up 169 points (an average of 28.1 points per game), slightly edging over his 27.5-point consensus line. Similarly, Stephon Castle has scored 110 points across six series starts (18.3 points per game), suggesting the over on his 16.5 points prop holds strong value.
For the Oklahoma City Thunder, Shai Gilgeous-Alexander has a steep 30.5-point line. Given his 146 points across six series games (averaging 24.3 points per game), selecting the under could be a logical pick. However, he is averaging 8.8 assists per game in the series (53 total), making the over on his 7.5 assists line extremely appealing. Meanwhile, De’Aaron Fox has comfortably cleared his 5.5 assists prop pace by dishing out 26 assists across just four games played in the series (6.5 assists per game).
How to Redeem Underdog Promo Code WTOP
Getting started and unlocking your bonus is a simple process. To claim your $50 in bonus entries, you must use the promo code WTOP during sign-up.
Begin by creating and registering a new account, which will require you to provide standard personal information to verify your identity. You must be a new user and meet all local age and region requirements to qualify. Once your account is set up, make a first-time deposit of at least $5 using one of the platform’s secure payment methods. Finally, place a $5 entry to officially activate the promotion and receive your $50 bonus.
When creating your entries, Underdog offers two distinct ways to play:
- Standard Entry: This option requires 2+ picks and offers the largest potential payout. However, there is no room for error—every single leg of your entry must hit for you to win.
- Flex Entry: If you prefer a bit of a safety net, you can choose to flex an entry with 3+ picks. While the maximum payout is slightly reduced, a flex entry ensures you can still receive some winnings even if one of your picks turns out to be incorrect.
