Dunkin’ aired a Super Bowl ad celebrating Boston’s 1990s legacy, offering free coffee for solving a math puzzle.

The 2026 Dunkin’ Super Bowl ad, “Good Will Dunkin,” stars Ben Affleck as a Boston blue-collar genius, celebrating the city’s 1990s cultural legacy with nods to “Cheers,” Tom Brady, and other icons. Jennifer Aniston made a cameo, and Ted Danson reprised his role as Sam Malone. To promote the ad, Dunkin’ offered 1.995 million free iced coffees on February 10 using the app code GOODWILLDUNKIN and challenged viewers to solve a real math problem from former NFL player and MIT professor John Urschel for additional free coffee.
