The NCAA Division I men's basketball tournament — March Madness — crowns its 2027 national champion in early April after three weeks of single-elimination games. This countdown runs to the title game.

Tens of millions fill out brackets each year trying to predict the chaos — and almost no one gets it perfect. The odds of a flawless bracket are astronomically small.
