To get the max value from the Underdog Fantasy sign-up offer, you need to deposit at least $2,000. All bonus cash from this promo has a 1x playthrough requirement on both your deposit and the bonus cash value.

Underdog DFS doesn't operate like traditional sportsbooks with the standard sports betting markets. Instead, you set a lineup with up to five picks from the MLB NLDS. Select "Higher" or "Lower" on specific statistical categories from the Philadelphia Phillies vs. New York Mets and the Los Angeles Dodgers vs. San Diego Padres games. The more selections you include, the bigger the payout.

Use the Underdog Fantasy Promo Code TOPACTION for MLB Postseason Today

Sign up with the Underdog Fantasy promo code TOPACTION to get bonus cash now. With the MLB Postseason in full swing, it's a great time to sign up and get up to $1,000 in bonus cash for your first lineup.

At Underdog Fantasy, there are two basic categories for lineups: Standard and Flex. With the former (Standard) every selection in your lineup must be correct to collect a payout. On the other hand, if you select the latter (Flex), you get a payout even if one of your picks loses.

So a $440 deposit gets $220 in bonus cash with the Underdog Fantasy promo code TOPACTION. Let's say I put down $130 on a five-pick Standard lineup:

  • Aaron Nola Higher than 5.5 Strikeouts
  • Bryce Harper Higher than 0.5 Total Bases
  • Francisco Lindor Lower than 7.5 Fantasy Points
  • Pete Alonso Higher than 0.5 Home Runs
  • Kyle Schwarber Higher than 0.5 Home Runs

As a Standard lineup, I get a $2,600 payout, if all five hit. If just one misses, I lose the $130 stake. That said, as a Flex lineup, I get a $1,300 payout if all five picks are correct or a $130 payout, if four of five are correct.

Critically, to meet the playthrough requirement, I need to create lineups worth $660 total over the ensuing 60 days to make any withdrawals from Underdog Fantasy.
