Abstract
Abstract A golf putting surface is provided that is adjustable in height at selected locations within the surface within a continuum of vertical positions by means of a plurality of height adjustment mechanisms. The height adjustment mechanisms are themselves adjustably located horizontally along substantially the entire perimeter of the surface to produce numerous surfaces with differing undulation. The surface is covered with one of a selection of interchangeable surface materials of differing friction and texture to use in combination with the undulating surface to simulate different playing conditions.
