Your performance in the Ranking will depend on the number of Cups you manage to accumulate by completing question streaks and Missions. Depending on this amount, you will either go up or down a League.
To be promoted to the next League, you will need to finish within the first 25 positions of your current one. You will be able to identify the position you will need to occupy to be promoted by a green bar or "promotion zone".
In case of finishing outside these first positions, under the red bar or "relegation zone", you will go down a category.
To access the Ranking section, press the Cup icon located in the lower right-hand corner of the screen.
