Every week you can rank in the League by playing matches in Arenas. Your ranking will depend on the money earned from playing Arena matches.

To be promoted to the next League, you need to end up in the promotion zone. Make sure to reach the promotion zone, since clubs who finish in the relegation zone will be returned to the lower League within the same League Tier. However, when you relegate to a lower League, you will never go under your reached League Tier. (e.g. Once you reach Pro League tier, you can't fall down to the Semi-pro anymore, you secured your stay in the Tier)

With 13 Leagues in Total, you can progress through multiple Arenas and collect money and rewards on your way to the top of the leaderboards. Besides the first one (Amateur), Leagues are divided into different tiers, with each tier containing three Leagues.

Rewards for achieved ranking on the League leaderboards depend on the League level, as well as tier. 

Find out more about tiers by tapping on the “View all Leagues” button available in the upper right corner of the League screen.
