How to Use Underdog Fantasy Promo Code LABSNEWS for NFL Lineup
Once you claim your welcome bonus with the Underdog Fantasy promo code LABSNEWS, it’s time to build your lineup. Simply pick any players from NFL Week 15, then choose “Higher” or “Lower” on their projections.
An Underdog lineup can include 2–8 picks. The more picks you add, the bigger your potential payout. Achieve a perfect 8-for-8 lineup, and you earn 120x your entry.
If your lineup has three or more picks, you select either the Standard or Flex option. The Standard lineup offers the largest payout but requires winning every pick. With the Flex lineup, you can still profit or get your stake back even if one pick loses, though the payout for a perfect lineup is slightly smaller.
