A billiard table or billiards table is a bounded table on which cue sports are played. In the modern era, all billiards tables provide a flat surface usually made of quarried slate, that is covered with cloth, and surrounded by vulcanized rubber cushions, with the whole thing elevated above the floor. More specific terms are used for specific sports, such as snooker table and pool table, and different-sized billiard balls are used on these table types. An obsolete term is billiard board, used in the 16th and 17th centuries.
