Golf balls are putted along a path toward a target zone. The width of the path is resolved into segments which define the target zone, bogey zones on opposite sides of the target zone, and multiple bogey zones outside of the bogey zones. The size of the target zone is varied from cycle to cycle to provide holes with different par values. A bonus zone in the center area of the target zone allows birdie and eagle scores to be achieved when a selected number of consecutive putts are made in the bonus zone. Each segment within the target zone is assigned a maximum allowable speed which increases toward the target zone center. Even if a putt is within the target zone, it is considered a miss if the maximum allowable speed for the putt location is exceeded. ## Claims ### Claim 1 Golf ball putting apparatus comprising: means for providing a path along which a ball may be putted, said path having a predetermined width dimension;

means for resolving the width dimension of said path into a preselected number of equally spaced points of resolution connected by segments each extending substantially the same distance; means for defining at one end of the path a target zone for the ball representative of a golf cup and having a width dimension coinciding with a selected number of adjacent segments; means for sensing the resolution point most closely coinciding with the center of a ball rolling to said one end of the path; means for detecting the speed of each ball at said one end of the path; means for assigning a maximum allowable ball speed to at least some selected resolution points located within the target zone and contiguous with each outer edge thereof; and means for indicating when the center of the ball coincides most closely with one of said selected resolution points and the ball speed exceeds the maximum allowable ball speed assigned to said one resolution point. ### Claim 10 (depends on 9) Apparatus as set forth in claim 9, wherein the maximum allowable ball speed assigned to said selected resolution points increases with increased distance of the resolution points from the closer outer edge of the target zone. ### Claim 11 (depends on 9) Apparatus as set forth in claim 9, wherein said indicating means includes means for audibly announcing that the ball speed exceeds the maximum allowable ball speed assigned to said one resolution point. ### Claim 12 (depends on 9) Apparatus as set forth in claim 9, including means for providing an indication of a bonus score if a selected number of consecutive balls are centered within selected segments of the target zone. ### Claim 13 Golf putting apparatus comprising: means for providing a path along which the ball may be putted, said path having a predetermined width dimension;
