How to Use the Underdog Promo Code for Sunday’s NBA Slate
Once you’ve created your account and funded your balance, head to the Underdog Fantasy pick’em section to explore a variety of NBA player projections. Available betting categories include points, rebounds, assists, steals, and combined stats like points + rebounds + assists. Your goal is to predict whether a player is going to record higher or lower than their projected stat line.
Underdog Fantasy allows you to combine up to six picks in a single entry, with a maximum payout of 35x. If your lineup includes at least three picks, you must choose between two play styles:
- Standard Entry: All picks must be correct to win up to 6x your wager.
- Flex Entry: A safer alternative with lower risk that still rewards winnings even if one pick falls short. Win 3x your stake if all picks hit and 1x if one pick is incorrect.
To showcase how this works, here’s an example of a three-pick lineup built using bonus funds from the Underdog promo code TOPACTION for Sunday’s biggest NBA matchups:
- Nikola Jokic (Nuggets) – Higher than 12.5 Rebounds
- Shai Gilgeous-Alexander (Thunder) – Lower than 32.5 Points
- Donovan Mitchell (Cavaliers) – Higher than 3.5 Three-Pointers Made
If you enter this lineup in Standard mode, you win 6x your wager if all three picks hit. Choosing Flex mode provides a 3x payout if all three selections win and still returns 1x if one pick falls short.
With major NBA games on the schedule, including Nuggets vs. Thunder at 1 p.m. ET on ABC and Cavaliers vs. Bucks at 8 p.m. ET, now is the perfect time to take advantage of Underdog Fantasy’s deposit match bonus.
