A billiard table has a substantially planar playing surface (2), preferably rectangular, limited at its periphery by retention edges (3), and bordered longitudinally by a concave playing surfaces (1) disposed between the planar playing surface (2) and the longitudinal retention edges (3). The concave playing surfaces (1) has a radius of curvature R comprised between 0.30 and 1.1 meter. The center C of the circle determining the radius of curvature R is situated on a straight line D perpendicular to the planar playing surface (2) and passes through a point of intersection between the planar playing surface (2) and the concave playing surface (1).
