Underdog Promo Code TOPACTION Yields $50 Bonus for Knicks vs. Spurs NBA Finals Picks
Sign up now using the Underdog promo code TOPACTION to secure a $50 welcome bonus to use on DFS picks on Knicks vs. Spurs in the NBA Finals at 8:30 p.m. ET on ABC. Underdog is a top DFS app that works very differently than traditional sports betting. You select Higher or Lower on player projections and combine them into entries. The more picks you add to your entry, the higher your payout multiplier becomes. Get started now with the NBA DFS picks on the market.
There are two different types of entries available to choose between at Underdog. Choose a Standard entry, which requires all of your picks to win to receive a payout. Alternatively, select a Flex entry that yields a payout if you win all of your picks or lose just one. The key difference comes in the payout multiplier, as perfection yields a much greater payout with a Standard due to the difficulty of winning.
Here is a look at an example of a $10 Standard entry I created with MLB DFS picks, which has a 5.7x payout multiplier:
- Jalen Brunson Higher Than 24.5 Points
- Victor Wembanyama Higher Than 26.5 Points
- Karl-Anthony Towns Higher Than 16.5 Points
With the Underdog promo code TOPACTION, I receive $50 in fantasy bonus entries regardless of the outcome of this entry. If all picks win, I receive a $57 payout that includes $47 in profit and $10 returned to my account.
