Underdog Fantasy Promo Code LABSBONUS: Submit NCAAF + NFL Lineup Today
Take advantage of the Underdog Fantasy promo code LABSBONUS and submit your $5 lineup using picks from both NCAAF and NFL games. From the FCS Championship and CFP to NFL Wild Card Weekend and beyond, Underdog gives you plenty of high-profile slates to build around.
For each player, select “Higher” or “Lower” on their projected stat line to add a pick to your entry. You can include anywhere from two to eight picks in a single lineup, with payouts reaching up to 120x, making it one of the most exciting formats in NFL DFS.
Once your lineup reaches three or more picks, you must choose between a Standard or Flex entry. The Standard option offers the highest possible payout, but every pick must win. Flex entries provide a safer path, allowing you to still profit even if one pick misses, though the payout is slightly smaller for a perfect card.
Below is a sample lineup featuring picks from the FCS Championship, CFP, and the NFL Playoffs. Be sure to use the Underdog promo code LABSBONUS at signup to unlock the $75 welcome offer and start building your entries today.
| Player | Team | Pick |

| Trinidad Chambliss | Ole Miss Rebels | Lower Than 23.5 Rushing Yards |
| Puka Nacua | Los Angeles Rams | Lower Than 0.5 Touchdowns |
