Underdog Promo Code TOPACTION: Get $75 in Bonus Entries for NFL Playoffs Wild Card Round
Register for a new DFS account now 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 both games in the Wild Card Round of the NFL playoffs today: Rams vs. Panthers at 4:30 p.m. ET or Packers vs. Bears at 8 p.m. ET.
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:
- Kyren Williams Higher Than 0.5 Fumbles Lost
- Tetairoa McMillan Higher Than 55.5 Receiving Yards
- Jordan Love Higher Than 223.5 Passing Yards
Suppose I place this entry as my $5 initial entry with the Underdog promo code TOPACTION, which has a 30x payout multiplier. Here is what I receive based on the outcome of it:
- If all of my picks win, I receive a $150 total payout ($145 profit + $5 entry back) and $75 in bonus entries.
- If one or more of my picks lose, I receive $75 in bonus entries.
