It contains 9 or 18 holes, which are sequentially numbered and spaced accordingly. Each hole has a certain number of required strokes, known as PAR, which is 3.4 or 5. Each hole is assigned a number, known as the Stroke Index (from 1 to 18), which determines the difference in difficulty of play between players.
A course containing 9 holes is referred to as a small course, while one with 18 holes is a full-sized course. A standard golf course consists of several different parts, which are characterized by different levels of grass trimming. There is an area of “wild grass,” grass of medium length, grass that is between 0.5 and 2 centimeters long (fairway-the main playing course), an area of grass half as long as 0.5-2 centimeters (fringe), an area of grass less than 5 millimeters long, where the flag and hole are located (green) and a starting area at the beginning of each hole, known as the tee.
A fun interpretation of the existence of 18 holes on a golf course is that a bottle of whiskey contains 18 shots - exactly one per hole.
