Nine Ball

Nine-ballMain article: Nine-ball

One of many correct nine ball racks: the 1 ball at the apex centered over the foot spot, the 9 ball at center, the other balls placed randomly, and all balls touching.Nine-ball uses only the 1 through 9 balls and cue ball. It is a rotation game: The player at the table must make legal contact with the lowest numbered ball on the table or a foul is called. The game is won by legally pocketing the nine ball. Nine-ball is the predominant professional game, though as of 2006–2008 there have been some suggestions that this may change, in favor of ten-ball.[18][clarification needed] There are many local and regional tours and tournaments that are contested with nine-ball. The World Pool-Billiard Association (WPA) and its American affiliate, the Billiard Congress of America (BCA), publish the World Standardized Rules. The European professional circuit has instituted rules changes, especially to make it more difficult to achieve a legal break shot.[18][19] The largest nine-ball tournaments are the independent US Open Nine-ball Championship and the WPA World Nine-ball Championship for men and women. Male professionals have a rather fragmented schedule of professional nine-ball tournaments. The United States Professional Pool Players Association (UPA) has been the most dominant association of the 1990s and 2000s. A hotly contested event is the annual Mosconi Cup, which pits invitational European and US teams against each other in one-on-one and scotch doubles nine-ball matches over a period of several days. The Mosconi Cup games are played under the more stringent European rules, as of 2007.[19]
