Eton Fives is a hand-ball game, played in a three-sided court. It is only played as "doubles" (i.e. by two teams of two players), there being no official "singles" version of the game. Players wear padded leather gloves, since the ball (which is slightly larger than a golf-ball and made of rubber and cork) is quite hard. It is in the same sporting "family" as other hand ball games such as Rugby Fives, Winchester Fives, American Handball, Irish Handball, and the various Basque games, Pelota Vasca.
