Basketball is one of the most popular sports in the world, played by millions of people across schools, colleges, amateur leagues, and professional organizations. Whether you’re a beginner learning the fundamentals, a parent trying to understand your child’s games, or a player looking to improve your knowledge, understanding basketball rules is essential.
What Is Basketball?
Basketball is a fast-paced team sport where two teams compete to score points by shooting a ball through the opponent’s hoop. The team with the most points at the end of the game wins.
The game was invented by Dr. James Naismith in 1891 and has evolved into one of the world’s most watched and played sports.
The objective is simple:
- Score more points than your opponent
- Defend your basket
- Follow official game rules and regulations
