{{Main|Eight-ball pool (British variation)}}

{{anchor|UK}}The British version of eight-ball, known internationally as either [[Blackball (pool)|blackball]] or simply eight-ball, has evolved into a separate game, retaining significant elements of earlier pub versions of the game, with additional influences from [[English billiards]] and [[snooker]]. It is popular in amateur and professional competition in the UK, Ireland, Australia and some other countries.

The game uses unnumbered, solid-colored object balls, typically red and yellow, with one black 8 ball. They are usually {{convert|2|in|mm}} or {{convert|2+1/16|in|mm}} in diameter, the latter being the same size as the balls used in snooker and English billiards. Tables are usually {{convert|7|ft|m|adj=on}} long, and feature pockets with rounded cushion openings, like snooker tables. Smaller {{convert|6|ft|m|adj=on}} tables are sometimes used in places where a larger table would be too large.

The rules of blackball differ from standard eight-ball in numerous ways, including the handling of fouls, which may give the opponent two shots, racking (the 8 ball, not the apex ball, goes on the spot), selection of which group of balls will be shot by which player, handling of {{cuegloss|frozen}} balls and {{cuegloss|snooker}}s, and many other details.

Internationally, the [[World Pool-Billiard Association]] and the [[World Eightball Pool Federation]] both publish rules and promote events. The two rule sets differ in some details regarding the penalties for fouls.
