Underdog Promo Code TOPACTION: Get $75 in Bonus Entries for Texans vs. Steelers
Sign up for a new DFS account today using the Underdog promo code TOPACTION and claim $75 in bonus entries once you play $5+ on the app. These bonus entries do not expire and can be utilized to play entries you create containing picks from any event, including tonight's Texans vs. Steelers matchup in the NFL playoffs.
There are two different entry formats available to choose between at Underdog Fantasy: 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 an entry I created for the NFL playoffs:
- Aaron Rodgers Lower Than 204.5 Passing Yards
- C.J. Stroud Higher Than 228.5 Passing Yards
- Nico Collins Higher Than 0.5 Rush + Rec TD
Suppose I place this entry as my $5 initial entry with the Underdog promo code TOPACTION, which has a 5.5x payout multiplier. Here is what I receive based on the outcome of it:
- If all of my picks win, I receive a $27.50 total payout ($22.50 profit + $5 entry back) and $75 in bonus entries.
- If one or more of my picks lose, I receive $75 in bonus entries.
