Chinese handball Chinese handball (known in its 3-or-more-player forms as "Ace-King-Queen", "King(s)", "Down the River" or "Slugs"), is a form of American handball popular on the streets of New York City, Philadelphia, and Bridgewater, New Jersey during the 1960s, '70s, and '80s and is still played today, mostly in New York City, Philadelphia, and San Diego. Different variations are played around the world. Its defining feature is that, unlike traditional handball, in Chinese or indirect handball, for a shot to be valid, the ball must hit the ground before it hits the wall. It would seem that this game, or mini variants of it, were highly popular almost worldwide in the 1950s, 1960s and 1970s.
