The Underdog promo code TOPACTION is a must-use offer for any new player looking to make NFL predictions on Week 18 games. Action Network sportsbook and DFS expert Daniel Preciado agrees with me, and suggests you give this offer a try to see what all the hype is about.

Between today's doubleheader of NFL games, there's more than enough player picks to consider putting money on. See a 4-pick entry I created below that includes one pick from each NFL team taking the field. Place your first entry on these picks, or create an entry of your own predictions to unlock $75 in bonus entries.

Before an Underdog pick 'em entry can be submitted, you must choose between making it a Standard or Flex entry. See how my 4-pick entry above pays out depending on which option you select.
- Standard Entry: Win 10x if all four of my NFL picks above are correct.
- Flex Entry: Win 6x if all four of my NFL predictions above hit. If three of four picks are right, the winnings are 1.5x.
