In the 1964 Tournament of Champions, it was Jack Nicklaus who sunk the longest putt ever made at 110 feet away, several times larger than your typical putting green! With (Probably) the World's Smallest Mini Golf, the cup is only about 200 millimeters. Not too big a distance, but with a pea-sized ball and a club not much longer than a toothpick, the scale brings about a whole new challenge.
