The Underdog Fantasy promo code TOPACTION comes with a 1x rollover requirement that must be fulfilled within 14 days. For instance, if you deposit $1,000, you must play through $500 on Underdog Fantasy within the 14-day window to withdraw winnings tied to the 50% match.
This sign-up bonus has a relatively lenient structure where your bonus cash is used before your deposited cash balance. This means once you’ve spent all your bonus cash, the rollover requirement is fulfilled, and any winnings are transferred to your available cash balance.
Use the Underdog Fantasy Promo Code TOPACTION for NFL Playoffs Lineups Today
Now that you’ve claimed the welcome offer and received your bonus cash using the Underdog Fantasy promo code TOPACTION, let’s explore how pick’em entries work. Choose "Higher" or "Lower" for player projections, combine them into a single entry, and decide between a Standard or Flex entry.
Standard entries offer the highest payout multiplier if all your picks are correct. Flex entries, on the other hand, provide lower payouts but come with a safety net—if you miss just one pick, you get a portion of your entry amount back. Any other outcomes result in a full loss.
Here is an example of an entry I created for the Divisional Round of the NFL playoffs:
- Puka Nacua HIGHER than 0.5 Rushing + Receiving Touchdowns
- Saquon Barkley HIGHER than 126.5 Rushing + Receiving Yards
- Derrick Henry HIGHER than 95.5 Rushing Yards
The payout on a Standard entry is 7.14x and a Flex entry provides a 3.57x payout if you win all picks or a 1.19x payout if you go 2-for-3. Suppose I place the lineup for $5 as a Standard entry. Here is what I get based on the outcome:
- If the lineup wins, I receive a $35.70 total payout that includes $30.70 in profit and my $5 entry amount returned to my account.
- If the lineup loses, I do not get anything back but work through a portion of the rollover requirement with the Underdog Fantasy promo code TOPACTION.
