Underdog's 'Keep Your Million' game debuts for NFL Week 1, giving users a virtual $1 million pot to split on over/under predictions. New customers can also claim a 50% deposit match up to $1,000 using code FOXSPORTS. The promotion coincides with the season opener between the Patriots and Seahawks.

Expanded Detail

The "Keep Your Million" game tasks participants with allocating a virtual seven-figure sum across over/under player prop questions, such as quarterback passing yardage, with winnings retained on the correct side. This debut aligns with the Patriots-Seahawks opener, where Seattle's Jaxon Smith-Njigba aims to extend his breakout 2025, while New England's newly acquired A.J. Brown joins quarterback Drake Maye under coach Mike Vrabel.

The broader Week 1 slate features a Thursday game in Melbourne between the 49ers and Rams, a full Sunday schedule, and a Monday night matchup between Denver and Kansas City. To claim the welcome offer, new users must register with personal details, apply the FOXSPORTS code, and make a qualifying deposit to receive the 50% match.

Context

This promotion could significantly boost casual fan engagement with NFL Week 1, as the free-to-play virtual pot lowers barriers to entry. However, the 50% deposit match may encourage new users to transition from free play to real-money wagering, potentially affecting household finances. The focus on player-specific over/unders could also shift viewing habits, making individual stat lines as compelling as game outcomes for a broader audience.
