Putting is a very important factor in golf playing. Above all, a putting distance feeling is the hardest to master, and many rounds in golf courses are said to be required for improving putting. Nevertheless, a putter mat is normally only 2- to 3-m long, and a carpet surface or the like that offers the same rolling as by golf greens is hardly available. Many smooth floor surfaces found in homes and firms cannot be used for putting practice due to excessive rolling of golf balls. It is an object of the present invention to eliminate these drawbacks. A ball implement for practicing golf putting is invented which includes a disc provided at the center thereof with a hole, and a main body having a cylindrical portion.
