Polo is a team sport played on horseback, where players use long-handled mallets to hit a ball into the opposing team's goal. The game is typically played on a large grass field, and each team consists of four players. Polo matches are divided into periods called chukkas, usually lasting seven minutes each, with teams switching sides after each chukka. The origins of polo date back to ancient Persia, where it was played as a training game for cavalry units. Today, it is popular in various countries, including Argentina, India, and the United States, and is often associated with luxury and high society.
