Underdog Promo Code ACTION Yields $50 Bonus for NBA Playoffs Now
Sign up with the Underdog promo code TOPACTION and play a $5+ initial entry to get $50 in bonus entries. Utilize them to play any NBA DFS picks on tonight's slate. Let's break down how entries work at Underdog using an example from both Magic vs. Pistons and Suns vs. Thunder.
There are two different entry formats to choose from: Standard and Flex. A Standard entry requires all of your picks to win to receive a payout, while a Flex entry requires you to win all picks or lose just one. The key difference is that a Flex entry provides a much smaller payout when you win all of your picks, while a Standard entry rewards you much more for the risk you take.
Here is a look at a $5 Standard entry I created (5.2x payout multiplier) that is comprised of picks from both games in the NBA playoffs tonight:
- Paolo Banchero Lower Than 20.5 Points
- Devin Booker Lower Than 23.5 Points
- Cade Cunningham Higher Than 43.5 Pts + Rebs + Asts
Here is what I get based on the outcome of the entry:
- If all of my picks win, I receive a $26 total payout ($21 profit + $5 entry back) and $50 in bonus entries.
- If one or more of my picks lose, I receive $50 in bonus entries.
Remember, the Underdog promo code TOPACTION is available to new users in AL, AK, AR, CA, DC, FL, GA, IL, IN, KS, ME, MS, MN, NE, NM, NC, ND, OK, OR, RI, SC, SD, TX, VT, VA, UT, WI, and WY.
