Underdog Promo Code TOPACTION: Play NFL & NCAAF Entries Today
When you register today for a new DFS account with the Underdog promo code TOPACTION, play a $5+ initial entry to secure $50 in bonus cash. This initial entry can be played on any event, including NFL and NCAAF.
There are two different entry formats to choose from at Underdog Fantasy. A Standard entry requires that you win all of your picks to receive a payout, while a Flex entry yields a payout if you win all of your picks or lose just one of them. The key difference between the two formats comes with the payout multipliers. Because of the difficulty of winning a Standard entry, you get paid out much more for winning than the Flex alternative.
Here is an example of an entry I created combining picks from the NFL and NCAAF this weekend:
- Josh Allen HIGHER than 233.5 Passing Yards
- Jahmyr Gibbs HIGHER than 27.5 Receiving Yards
- Garrett Nussmeier HIGHER than 281,5 Passing Yards
Say I place the entry above as my first with the Underdog Fantasy promo code ACTION for $5. This entry has a 6x payout multiplier.
- If all picks win, I receive a $30 total payout ($25 profit + $5 entry returned) and $50 in bonus cash.
- If one or more picks lose, I receive $50 in bonus cash only.
Remember to use the Underdog promo code TOPACTION to claim your bonus today.
