Abstract: Multiple variations on a novel device and method for improving golf-putting skills are disclosed. Specifically, the present invention relates to the construction and use of an asymmetrical golf-putting target zone that encourages users to direct putts to land within a specific two-putt range on the high-percentage side of the cup, where the high-percentage side is determined by the slope and pitch of the putting surface. The motivation for the asymmetry is disclosed, as are the principles for constructing, implementing, and using the asymmetrical zone. Specifically, the axis separating the asymmetrical subregions of the zone is placed either approximately perpendicular to, or approximately coincident upon, an ideal line of the ball's approach and is oriented such that the larger subregion is placed on the side of the cup with the higher elevation, or on the side of the cup further away from the putting location if the putting surface is flat.

Abstract: A golf practice hole with a variable diameter rim provides a flexible material positioned over a series of radially-movable supports that each define a portion of an edge or rim of a hole. The flexible material is typically provided with expansion areas that can include slits that define separate flaps of material. The flaps of material are tensioned beneath the movable supports to maintain the flaps in engagement with the supports. As the supports are moved radially-inwardly and radially-outwardly, the material follows the supports and defines a continuous surface above the rim throughout a range of movement of the supports. The range of movement defines a corresponding range of hole rim diameters. The flexible surface remains free of discontinuities and breaks despite diametral changes in the rim and provides an improved playing surface.
