os cinco marias is essentially a version of jacks - a player places five small stones or similar-sized objects on the ground in a circle. throwing one stone into the air, he picks up one stone before catching the falling rock. in the next round, the player is obligated to pick up two stones before catching the airborne one, and so on.

much as in jacks, the winner is the first one to collect all the stones and catch the flying projectile successfully.

pega moneda - or 'hit the coin' - is related to marbles and any number of throwing skill games the world over.
