Bracket (tournament)

A bracket or tournament bracket is a tree-like diagram that represents the series of games played during a knockout tournament. Different knockout tournament formats have different brackets; the simplest and most common is that of the single-elimination tournament. The name “bracket” is American English, derived from the resemblance of the links in the tree diagram to the bracket punctuation symbol ] or [. The closest British term is draw, although this implies an element of chance, whereas some brackets are determined entirely by seeding.
