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 1950s, ‘60s, ‘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.
 
Another similar variation of the game is wallball.
 
Game play
The purpose of the game is to hit the ball (either a racquetball, or a spaldeen, kick pinkie, tennis ball or soft golf ball) in such a way that the opponent cannot return the shot before its second bounce after hitting the wall. In its simplest form two players can play for points. More players can play an elimination game or Ace-King-Queen.
