Underdog Promo Code ACTION Yields $50 Bonus with Best Spurs vs. Thunder DFS Promo
Sign up now using the Underdog promo code TOPACTION to secure a $50 welcome bonus to use on DFS picks on Spurs vs. Thunder. 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 top Spurs vs. Thunder DFS promo 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 NBA DFS picks, which has a 6x payout multiplier:
- Shai Gilgeous-Alexander Higher Than 30.5 Points
- Victor Wembanyama Lower Than 12.5 Rebounds
- Jared McCain Higher Than 2.5 Three Pointers Made
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 $60 payout that includes $50 in profit and $10 returned to my account.
