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.

Another similar variation of the game is wallball.

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.

In some versions of Ace-King-Queen, players have their own squares, in others the "court"(usually improvised) is shared.

With more than two players, each player has a place in the order. In some versions this order is enacted down the wall with each player having their own square. As the ball bounces off the wall from the previous player, the next player must reach it and make a legal shot. That player would either return the ball (the same way) back to the server or another player down the line. The line consists of 2 to 20 players, with the first player being the "Ace". The second player is the "King" and the third is the "Queen". The final player in line is known as an "Ace Killer" because of his opportune position to take out the "Ace". In some versions a player may continue to hit the ball in his own box as long as he desires. This leads to set up shots where smaller and smaller bounces produce a difficult 'baby' shot that is sent to the next box. Alternatively, low, long strokes develop a hard to return power shot to another box, or 'Baltimore Chops' a high bouncing shot. Some local rules may vary such as an 'Ace' knocked out of the lead box does not get a letter.

If a ball takes an erratic bounce due to a crack, or obstacle, on the court a player may call 'Hindoo' (from 'hinder' in Handball) and the ball is replayed with no letter assigned, though some play the court as it is, with no recourse.
