Almost all marble games involve a relatively smooth, flat surface, indoors or outside, and shooting a large marble (called a shooter, taw, or boss) at smaller target marbles (called mibs, ducks, dibs, hoodles, immies, commies, or kimmies) with the intention of sending the smaller ones outside a circle or beyond safe territory. Players who send their opponents' mibs beyond the protection of the ring win the marble, if the game is for keepsies. If players agree to play friendlies, however, everyone keeps their own marbles at the end of the game regardless of which marbles roll outside the circle.
