Red Rover is an outdoor game played primarily by children on playgrounds. "Red Rover" was very popular into the 1970s. Players on a team hold hands, forming a "chain". The leader of a team will call a player from the opposing team. That player must try and break through two players' hands (a link) to stay on their own team. If the player is not able to break through the link, that team will gain control of that player. Before a player would try to break the link, the link would normally say "Red Rover, Red Rover, we call (player's name) over!"
Typically, the weaker players are chosen first to increase the chance of taking them.
When only one player is left on a team, they must try and break through a link. If they do not succeed, the opposing team wins. Otherwise, they are able to get a player back for their team. _Wikipedia
