A leaderboard is a ranking system that displays the performance of individuals or teams in a competition or game. It shows who is doing the best based on specific criteria, such as points scored or tasks completed. Leaderboards are commonly used in video games, sports, and educational platforms to motivate participants and encourage friendly competition. In many cases, leaderboards can be found online, allowing players to compare their scores with others around the world. They often include features like usernames, scores, and rankings, making it easy for everyone to see how they stack up against their peers.
