What's the difference. From what I can tell… Billiards is a catch-all term used to describe all cue sports (games played on a raised table with balls and cues). However, it has become typical for many people to use the term "billiards" when referring to carom games (games played on tables without pockets) such as 3-cushion billiards and balkline billiards. Pool is an American form of billiards which is also known as "pocket billiards". Snooker is a form of billiards played on very large tables with very small pockets. Snooker is not as popular in America as it is in Europe, Asia, and Canada. There are other forms of billiards such as English Billiards, Bagatelle, Russian Billiards, even bumper pool, etc. , but they all fall under the larger category of billiards.
