Kliker

Draw a circle on bare dirt or pavement and have each player place an agreed number of marbles inside it.

Decide turn order, then each player in turn crouches outside the circle and flicks their own larger shooter marble toward the marbles inside using their thumb and finger.

Any marble knocked completely outside the circle by a successful flick is won and kept by the player who knocked it out.

If a player's shooter marble stops inside the circle instead of returning outside, they may lose their next turn or forfeit the shooter, depending on the house rule agreed beforehand.

Players take turns shooting from wherever their marble came to rest on the previous turn, aiming for marbles still remaining in the circle.

The game ends once the circle is empty, and whoever collected the most marbles is the winner.
