Round Robin
A tournament format in which every participant plays every other participant an equal number of times.
Round robins are considered the fairest tournament format since results depend only on head-to-head play, but they require far more rounds than a Swiss system for large fields.
Etymology
Etymonline defines round robin as a petition or complaint signed in a circle to disguise the order in which names were affixed, dated 1730, originally in reference to sailors, and records the tournament sense — “a kind of tournament in which each player plays the others” — from 1895. A popular alternative derivation holds the term comes from French rond (“round”) ruban (“ribbon”), describing a petition signed in circular format so no name is first or last, with “ruban” supposedly corrupted to “robin” over time. Etymonline, the stricter source, does not endorse that French story, so it should be treated as a traditional explanation rather than settled fact. Either way, the sporting meaning descends from the circular petition: in a round robin, as on the petition, nobody is placed first or last.
First documented: 1730
