What is mini Golf?

Mini golf, also known as miniature golf, or putt putt, is an fallout of golf focusing solely on the putting aspect of its parent game.

Mini Golf with numbers

Mini golf is played on courses consisting of a series of 9 holes similar to its parent, but characterized by their short length (usually within 10 yards from tee to cup), the use of artificial turf putting green surfaces.

Min golf surfaces

Miniature golf surfaces are such as green grass carpet, artificial turf and concrete, a geometric layout often requiring non-traditional putting lines such as bank shots, and artificial obstacles such as tunnels, ramps, concrete/metal/fiberglass forms, and moving obstacles such as windmills. 

When miniature golf retains many of these characteristics but without the use of any props or obstacles, it is purely a mini version of its parent game.
