Red Rover is a traditional outdoor game played by children. It involves two teams forming lines by holding hands, with one team calling a player from the opposing team to run and break through their line. If the runner breaks through, they can take a player back to their team. If not, they join the opposing team. The game continues until one team has all the players. Red Rover encourages teamwork, strategy, and physical activity. It is often played in parks or schoolyards and is popular during recess or family gatherings.
