Kick the Can

Boy playing Kick the Can
A classic children's game, Kick the Can has elements of hide and seek, tag, and capture the flag in its game play. The rules of the game are simple and can be played outdoors in a variety of settings, including back yards, streets, or open spaces that allow for hiding places for children. Rather than using a ball, the only piece of equipment is an object that can be kicked. The name of the game is Kick the Can, because often a discarded empty can from the trash is used that can have rocks inserted into it to make noise.


Played with elements similar to baseball and soccer, one of the most popular children's games on the playground is kickball.
