This unique putting game is a fun and entertaining game for two or four players of all ages. Four players can be divided into two teams. Played like tic-tac-toe, the object is to get three golf balls either across, up & down, or diagonally. The degree of difficulty is determined by how far you stand back from the device. This unique and challenging game comes with five colored golf balls, five white golf balls and the heavy duty durable game board. This is a sure hit during those inclement weather days at home or in the office. Keep your putting game sharp and your competitive juices flowing during those stormy winter days when golf courses are unplayable.
