Underdog Fantasy Promo Code TOPACTION: How to Submit NFL Week 17 Lineup
Take advantage of the Underdog promo code TOPACTION and build your NFL Week 17 lineup. Before diving into lineup construction, check out this expert insight from DFS analyst Chris Ilenstine on why Underdog’s welcome offer gives players a real edge this week:
“Underdog’s welcome offer gives you a real edge in Week 17. With the $75 bonus, you can build higher-upside lineups, take smart swings on projections you trust, and maximize value right from your first entry.” — Chris Ilenstine
Head over to Underdog and begin building your lineup by choosing “Higher” or “Lower” on player projections. Each selection adds a pick to your lineup, with the option to include up to eight total picks. If you go a perfect 8-for-8, Underdog offers a massive payout of 120x your entry.
When your NFL Week 17 lineup includes three or more picks, you must choose between a Standard or Flex entry. Standard entries offer the highest payout, but every pick must win. Flex entries provide a lower maximum payout, but still allow you to profit, or even get your stake back, if one pick misses, making them a popular option for balanced risk.
Now is the perfect time to get started. Use the Underdog promo code TOPACTION to claim a $75 welcome bonus, then create your own NFL Week 17 lineup or check out the example below to get inspired.
| Player | Team | Pick |
|---|---|---|
| De'Von Achane | Miami Dolphins | Higher Than 72.5 Rushing Yards |
| Jalen Hurts | Philadelphia Eagles | Lower Than 192.5 Passing Yards |
| Jauan Jennings | San Francisco 49ers | Higher Than 59.5 Receiving Yards |
