Skully

Street game in 1950s Brooklyn using a square, chalked grid, and employing bottlecaps for playing pieces. The grid is usually marked with the corners being numbered 1 through 4, and the midpoints of the sides of the square 5 through 8. The numbers are placed so that a playing piece, which is propelled by a flick of the fingers as in marbles, must traverse across the center of the square. Two additional squares, one within the other, are chalked in the center. The area between the outer and inner squares is called "Jail," and the area within the centermost square is called "Home." The object of the game is to get one's piece Home. The only way to get a piece out of Jail is to knock it out deliberately with another of one's own playing pieces, or if an inadvertent collision between the Jailed piece and another player's knocks it out.
