From White Belt to Brown Belt, you need to collect a certain number of belts to move up to the next class. Once you reach Red Belt, your promotion depends on your leaderboard ranking. Placing in the top 20 will promote you to the next belt class, while finishing in the bottom 20 will result in a demotion to a lower Belt Class. So, aim to earn as many Belts as you can and see where you stand in the leaderboards!
