A pool table is a rectangular table used for playing billiards games, such as pool, snooker, and carom. It is typically covered with a green or blue felt surface and has six pockets along the edges. Players use a long stick called a cue to strike balls, aiming to sink them into the pockets. Pool tables come in various sizes, with the most common being 7, 8, and 9 feet long. They are made from sturdy materials like wood and slate to ensure durability and a smooth playing surface. Pool tables are popular in homes, bars, and recreational centers.
