A round of golf typically consists of playing 18 holes on a golf course. Each hole has a tee box, fairway, and green, with a flag marking the hole's location. Players aim to hit a small ball into each hole using as few strokes as possible. The total number of strokes taken to complete all 18 holes determines a player's score. Golf courses can vary in difficulty, with different layouts and obstacles such as sand traps and water hazards. Players often keep track of their scores using a scorecard, which helps them monitor their performance and improve their skills over time.
