Underdog Promo Code TOPACTION: Create an Entry With NBA and NCAAB Picks Now
Register with the Underdog promo code TOPACTION and submit a $5 DFS entry using picks from NBA or NCAAB games. Once your entry is submitted, Underdog Fantasy credits your account with $75 in bonus entries, regardless of how your lineup finishes. That guaranteed return makes the Play $5, Get $75 deal one of the best DFS promotions available today.
To build your lineup, choose two to eight players and decide whether each will finish Higher or Lower than their listed stat projection. Adding more selections increases your payout multiplier, giving your entry more upside.
The example below shows how to structure a lineup with NBA and NCAAB picks. After signing up with the Underdog promo code TOPACTION, you can follow that template or create a custom entry to chase a larger payout on one of today’s top DFS platforms.
- Darryn Peterson to get "Higher" than 20.5 points (CBB)
- Tre White to get "Higher" than 7.0 rebounds (CBB)
- Brayden Burries to get "Lower" than 15.5 points (CBB)
Once you finalize your picks using the Underdog promo code TOPACTION, select the entry format that matches how much risk you want to take on. A Standard Entry offers the biggest payout potential, but it requires a perfect lineup with every pick hitting. A Flex Entry trades some upside for security by allowing one incorrect pick while reducing the overall multiplier.
To break it down, a three-pick Standard Entry returns 6x your stake if all selections are correct. Build that same lineup as a Flex Entry and the payout structure changes: you earn 3x if every pick hits, or 1x if one selection misses, giving you a cushion without fully sacrificing upside.
