Five-pin billiards or simply five-pins or 5-pins (Italian: ; Spanish: ), is today usually a carom billiards form of cue sport, though sometimes still played on a pocket table. In addition to the customary three balls of most carom games, it makes use of a set of five upright pins (skittles) arranged in a "+" pattern at the center of the table. The game is popular especially in Italy (where it originated) and Argentina, but also in some other parts of Latin America and Europe, with international, televised professional tournaments (for the carom version only). It is sometimes referred to as Italian five-pins or Italian billiards (Italian: ), or as (in Italian and Spanish). A variant of the game, or nine-pins, adds additional skittles to the formation. A related pocket game, with larger pins, is played in Scandinavia and is referred to in English as Danish pin billiards, with a Swedish variant that has some rules more similar to the Italian game. History Until the late 1980s, the game (with some rules differences) was a form of pocket billiards, known in English as Italian skittle pool, and was principally played in pubs, with an object ball that was smaller than the two cue balls. Professional and regulated amateur play today exclusively uses pocketless tables and equal-sized balls. Professional competition began in 1965, and play is centered in billiard parlors, with players competing in provincial, regional, and national federations. The pocket version is still favored by some in amateur play. Equipment and setup The regulation game is played on a normal pocketless carom billiards table, with standardized playing surface dimensions of 1.42 by 2.84 m (approximately 4-2/3 by 9-1/3 ft), plus/minus 5 mm (approx. 0.2 in), from to cushion. The slate of the table must be heated to about 5 degrees C (9 degrees F) above room temperature, which helps to keep moisture out of the cloth to aid the balls rolling and rebounding in a consistent manner, and generally makes the table play "faster". In informal play, an unheated table is often used. Like most other carom games, five-pins requires three standard carom billiard balls of equal diameter: a for the first player, typically plain white, another cue ball for the second player, historically white with a spot but now typically yellow, and a red ,. The balls are in diameter and weigh between ; 7.5 oz is average). The
