Knikkeren

Draw a circle on flat ground or dirt and have each player place an equal number of marbles inside it.

Players take turns crouching outside the circle and flicking a shooter marble with a thumb to knock others out.

Any marble knocked completely outside the circle is kept by the player who shot it.

If the shooter marble stays inside the circle after a turn, the next player may aim at it as well as the others.

Play continues around the group until all marbles have been knocked out, and whoever collected the most wins.
