The Underdog Fantasy promo code TOPACTION has a 1x rollover requirement that must be met within 14 days. For example, if you deposit $1,000, you need to wager $500 on Underdog Fantasy during this 14-day period before you can withdraw any winnings associated with the 50% match.
This welcome bonus is structured in a lenient way—your bonus cash is used before your deposit funds. Once you've used up all your bonus cash, the rollover requirement is fulfilled, and any resulting winnings are moved to your available cash balance.
Use Underdog Fantasy Promo Code TOPACTION for Lineups on NFL Playoffs Today
Now that you've taken advantage of the welcome offer and received bonus cash using the Underdog Fantasy promo code TOPACTION, let’s take a closer look at how pick’em entries work. You select "Higher" or "Lower" based on player projections, combine your choices into one entry, and opt for either a Standard or Flex entry format.
Standard entries deliver the highest payout multiplier if every pick is correct. In contrast, Flex entries offer lower payouts but include a safety net—if you only miss one pick, you'll recover a portion of your entry amount. Any other outcome results in a complete loss.
Here is an example of a lineup I created that combines picks from Commanders vs. Eagles in the NFC Championship and Bills vs. Chiefs in the AFC Championship:
- Jayden Daniels HIGHER than 224.5 Passing Yards
- Saquon Barkley HIGHER than 128.5 Rushing Yards
- Josh Allen LOWER than 20.5 Completions
The payout multiplier for a Standard entry is 5.63x, and a perfect Flex entry delivers a 2.81x payout. If you win 2-of-3 picks with a Flex, you get 1.02x. Suppose I place the lineup above as a Standard entry for $10.
- If all picks win, I receive a $56.30 total payout that includes $46.30 in profit and my $10 entry amount.
- If one or more picks lose, I lose my entry amount, but work through a portion of the rollover with the Underdog Fantasy promo code TOPACTION.
