Underdog is launching a new promo for the new NFL season kicking off today. Keep Your Million for Week 1, giving fans a new way to follow the biggest games on the opening slate. New users can enter promo code FOXSPORTS to unlock a 50% first-time deposit match worth up to $1,000 in bonus funds, then jump into Underdog’s free-to-play Keep Your Million survival game for a chance to work through a virtual $1 million bonus-funds pot.
The season kicks off today with a Super Bowl rematch between the New England Patriots and Seattle Seahawks. Seattle will look for Jaxon Smith-Njigba to keep up where he left off in his monster 2025 season.
Another superstar receiver is looking to make an impact, this time on a different team. A.J. Brown was traded to the Patriots in the offseason, pairing him with Drake Maye and former head coach Mike Vrabel.
After today’s opener, Week 1 continues with the 49ers facing the Rams on Thursday in Australia, then Sunday continues the full slate of matchups featuring some of the top contenders and teams who could be the biggest surprises.
Keep Your Million lets eligible customers put their football knowledge to the test. Every eligible customer receives a virtual $1,000,000 pot in bonus funds, then picks a ‘Higher’ or ‘Lower’ question, such as whether a quarterback will finish above or below a passing-yard total. Players split their million between the two sides, lock in their pick before the game and keep whatever they placed on the winning side once the result settles.
New users can enter promo code FOXSPORTS to get the 50% first-time deposit match worth up to $1,000 in bonus funds and jump into Keep Your Million for Week 1.
