Abstract: A practice putting green includes an elongated plank having a top wall and a plurality of depending, longitudinally extending ribs that stiffen the top wall against sagging along the length of the plank while allowing the top wall to twist under the weight of the plank. A putting surface is supported on the top wall, and a hole sized for receipt of golf balls extends through both the putting surface and the top wall. Legs are provided for independently adjusting the height of the putting surface at each corner, and the top wall twists under the weight of the plank to assume the shape dictated by the position of the legs. A system incorporating the putting green includes an elongated base positionable beside the green, a ball holding tray, and a catch tray positionable beneath the hole.
