Underdog Promo Code TOPACTION: Make NBA and NFL DFS Picks
There are endless possibilities to construct a lineup of picks once you utilize the Underdog promo codeTOPACTION. Between the NBA today and Super Bowl LX on Feb. 8, Underdog has a plethora of player pick 'em markets on hand.
Remember that to unlock $75 in fantasy bonus entries, you must place $5+ on your first entry. As long as there are at least three total entries from at least two teams, your entry qualifies.
Now that you know how the Underdog promo codeTOPACTIONÂ pays out bonus entries, it's time to sign up and get them in your account. Consider my entry below that combines both NBA and NFL DFS picks. Use any of these selections in an entry of your own today.
| Player | Team | Pick |
|---|---|---|
| Kevin Durant | Houston Rockets | Lower Than 25.5 Points |
| Cooper Flagg | Dallas Mavericks | Higher Than 18.5 Points |
| Drake Maye | New England Patriots | Lower Than 225.5 Passing Yards |
| Cooper Kupp | Seattle Seahawks | Higher Than 2.5 Receptions |
Once you put your picks into an entry, you must pick between a Standard or Flex payout before you submit it. The 4-pick entry I made above pays me 10x when I select Standard and go four-for-four on my picks. If I get all four picks right on a Flex entry, I win just 6x. That said, the benefit to a Flex entry is I win 1.5x as long as three of my picks hit.
