Eight-ball pool (British variation)

The English-originating version of eight-ball pool, also known as English pool, English eight-ball, blackball, or simply reds and yellows, is a pool game played with sixteen balls (a cue ball and fifteen usually unnumbered object balls) on a small pool table with six pockets. It originated in the United Kingdom and is played in the Commonwealth countries such as Australia and South Africa. In the UK and Ireland it is usually called simply "pool".

The English version of eight-ball has two main sets of playing rules used in professional play; those of the World Pool-Billiard Association (WPA), known as "blackball rules", and the code of the World Eightball Pool Federation (WEPF), known as "international rules".
