Skully (also called skelly, skellies, skelsy, skellzies, scully, skelzy, scummy top, tops, loadies or caps) is a children's game played on the streets of New York City and other urban areas.[1] Sketched on the street usually in chalk, a skully board allows a game for two to six players. A sidewalk is sometimes used, offering greater protection from vehicular traffic; however, the asphalt on a typical city street is smoother and provides better game play than a bumpy concrete sidewalk.
Game time varies, but a match of two to three players is usually completed in 20 minutes. Local variations in rules are common and make it difficult to document the game. Rule variations are agreed upon by players before starting a game, especially when players from different neighborhoods play against each other.
