The “First Four” are the four first-round games. Two games match number 16 seeds against each other, and the other two games feature the last four at-large teams selected into the tournament. The winners advance to the second round.
Each of the four regions consists of 16 teams that are seeded number 1 to number 16. In the second round, teams are paired according to seed. The number 1 seed faces number 16, number 2 faces number 15, number 3 faces number 14, and so forth.
The sixteen teams that advance beyond their second and third-round games are referred to as the “Sweet Sixteen.” The remaining eight teams are called the “Elite Eight,” and the last four teams are the “Final Four.”
