The ranking is divided into leagues, each league will be composed of 50 users, and, depending on your performance and the points you get, you will be able to move up or down in the league.
You will be able to see within the same League the position you need to occupy to move up to the next League; if you finish out of these positions, you will move down one category.
To access the Ranking, go to the first Trophy icon in the bottom left corner of your home screen.
