Underdog Fantasy Promo Code FOXSPORTS: Keep Your Million Promotion Launches for Week 1 of the NFL Season

Underdog launched a Week 1 promo called Keep Your Million — new users can enter code FOXSPORTS for a 50% first-time deposit match (up to $1,000).
The free-to-play Keep Your Million game gives eligible players a virtual $1,000,000 to split on higher/lower prop questions and keep whatever is on the winning side.
Season opens with a Patriots–Seahawks Super Bowl rematch (watch for Jaxon Smith‑Njigba and A.J. Brown’s move to New England), followed by a 49ers–Rams game in Australia and a full Week 1 slate.
