 The remaining 36 bids were granted on an "at-large" basis, which were extended by the NCAA Selection Committee to the teams it deems to be the best 36 teams that did not receive automatic bids.Eight teams—the four lowest-seeded automatic qualifiers and the four lowest-seeded at-large teams—played in the First Four (the successor to what had been popularly known as "play-in games" through the 2010 Tournament).The winners of these games advanced to the First Round (Round of 64).
