How the Underdog Promo Code TOPACTION Works for NBA Picks on Monday
Register with the Underdog promo code TOPACTION, play $5+ and get $75 in fantasy bonus entries to utilize for any NBA game. Let's break down how entries work at Underdog.
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 an example of a $5 Standard entry I created that contains NBA picks, which has a 5.4x payout multiplier:
- Kevin Durant Higher Than 25.5 Points
- Nikola Jokic Higher Than 53.5 Pts + Rebs + Asts
- Jaylen Brown Lower Than 7.5 Assists
Here is what I receive based on the outcome of the entry:
- If all of my picks win, I receive a $27 total payout ($22 profit + $5 entry back) and $75 in bonus entries.
- If one or more of my picks lose, I receive $75 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.
