Red Rover

Red rover (also known as forcing the city gates and octopus tag) is an outdoor game played primarily by children on playgrounds. This 19th-century children's group game (requiring around 10 or more players total) is thought to have originated in Britain and then spread to Australia, Canada and the United States.

Røver is a Norwegian word for "pirate", so perhaps the early British were showing bravery by daring the Viking raiders to "come over". The 1829 book titled The Red Rover: A Tale by James Fenimore Cooper describes the exploits of a pirate called "Red Rover".
