The League system helps order Clans by their levels of game activity.
There are 5 Leagues available at the moment:
- Bronze
- Silver
- Gold
- Diamond
- Master

In turn, Leagues are made up of Divisions, and each of those can include up to 10 Clans. The higher the League, the greater the reward its Clanmates get for Clan Challenges, but the requirements for completing these Challenges also go up respectively. Also, a higher League implies a wider range of items available for purchase in the Clan Shop.

All the regular activities are available to the Clans inside any League. You can attack all the Clans that belong to the same Division as you.

Moving up or down a League occurs when a Season is over. Season defines the period of time during which Clans within Divisions challenge one another.
Seasonal results determine the ratings of all the Clans, and that, in turn, indicates whether any given Clan moves up a League, stays in its current League, or moves down a League.

All the Clans are sorted by their rating (in descending order) within each Division:
- If two Clans have the same rating, the Clan with a greater total Collection Power between all of its Clanmates will take up a higher position;
- If two Clans have the same rating AND the same total Collection Power, the Clan with the greater Honor Points count in their Treasury will take up a higher position;
- If even the Honor Points count is the same, too, the Clan that was created earlier will prevail in the rating chart.

All the Clans created throughout the Season get attributed to a separate pre-season League; its Divisions can also include up to 10 Clans each.
When a new Season starts, all the Clans from this pre-season League move on to the Bronze League regardless of their results.
