    Abstract: A golf putting practice device and ball is provided, wherein the ball has a flat end and a friction face which allow the putting practice ball to slide across the level putting surface of the putting practice device. The specific coefficient of friction provided by the friction face of the putting practice ball reduces the speed and the distance the putting practice ball travels over a putting surface of the putting practice device.
