    Abstract: A scorecard for use when playing a game of golf, or a simulated golf game at a practise facility, wherein the scorecard comprises a series of maps depicting each golf hole on the course, and wherein a grid system overlays the maps of the golf hole. The grid lines on each map for each hole provide an indication of yardages so that the golfer can determine strategies for playing the hole, and then record the outcome of each shot. The same scorecard can be used in playing a simulated golf game at a driving range which is marked with a grid system which correlates to the grid system depicted on the scorecard.
