Goriziana or nine-pin billiards (also known as nine-pins, 9-pins, etc.) is a carom billiards game, especially popular in Italy.

Like the cue sport most closely related to it, five-pin billiards, goriziana is played on a 284 cm by 142 cm table.

In goriziana, nine pins sit in the middle of the table (this area is called castello which is Italian for "castle"). Three balls are used, of which two are cue balls. The game is played by two teams of one or two players. Each team or player aims to hit the opponent's ball and, from there, score points by striking the red ball, or by making the opponent's balls or the red ball knock over the pins.

Unlike in many games, shots are always taken in rotation – the same player or team never shoots twice in a row, even if they have scored. The only exception is if the opponent fouls before shooting, such as by moving one of the balls accidentally. Play continues until one player or team wins by being the first to reach or exceed a specific number of points (usually 200 or 300). This number is agreed upon beforehand by the players.

The main difference between five-pins and nine-pins is in scoring. Point values are more complex than and increased from those of the simpler five-pin game.

Scoring:

In case of a foul, two points are deducted, and any points the shooter would have earned on the foul shot are nullified. Examples of fouls:

Goriziana is primarily popular in Italy, and amateur players there have developed many variants of the game. Some of these variants are played in tournaments.
