The World Eightball Pool Federation (WEPF) is an international pool governing body overseeing international tournaments and rankings in the British-originating variant of eight-ball pool played with red and yellow unnumbered balls instead of the stripes and solids numbered balls. WEPF competes for authority and membership with the World Pool-Billiard Association (WPA), which oversees its own tournaments and slightly different rules under the name blackball. WEPF events are held principally in the United Kingdom and Commonwealth of Nations. From Wikipedia
