Marbles is a game believed to involve drawing a chalk circle and populating it with collectible glass marbles of varying color and size. Since the last person who actually knew how to play "marbles" passed away in 1956, modern game theoreticians can only speculate about the rules:

• Draw a circle of chalk on the ground.
• One player adds some, but not all, of their marbles.
• Another player adds a portion of their marbles.
• The players shake hands to agree that "marbles" is about to be played.
• Marbles are rolled (flicked?) at one another to result in some marbles entering the circle, while others, through gentle collision, are pushed out.
• A dog with an eye patch looks on warily, his loyalties unknown.
• A play or move results in one player getting to keep all the marbles, hence the still relevant expression "This one is for all the marbles."
• The players once again shake hands and return to their Victorian boys' academy, shipyard, or World War I trench, although one player's pockets, with every footstep, now clatter with the reminder that he has robbed the other player of the entirety of his worldly possessions.
• The half-blind dog sets off alongside the nearest set of train tracks, disappearing in a cloud of sun-bleached dust.
