The National Collegiate Athletic Association (NCAA) men's Division I basketball tournament, played in the United States each March, involves the best college teams in the nation, playing an elimination-style tournament. Games are played in rounds; winning teams in each round continue, while losers are eliminated. There are the following rounds: first round, second round, regional semifinal,

regional final, national semifinal, and national final. Many teams pair up to play games in the first round.
