"Trophy Leagues are groups of players that are all within the same trophy range. While in a Trophy League, each multiplayer victory will award a loot bonus based on league level."
Leagues are ranges of trophies in which players are ranked in.
Leagues offer a Loot Bonus at the end of each battle, which adds to the loot that a player got from the battle. The higher the league, the better the bonus. Dark elixir loot bonus begins at Crystal III league. In addition, leagues also offer a better Star Loot bonus the higher league you are.
Joining A League
Players become unranked at the end of each season.
To join a league, start by completing one multiplayer attack while being over the trophy limit of a league. The lowest league, Bronze III, is at 400 trophies.
At the end of this attack (regardless of victory or defeat), as long as your trophy count is higher than 400, you will be automatically placed into an appropriate league based on the league level's trophy range.
By reaching a certain trophy threshold, players will be promoted to a higher league. This trophy threshold is set between 100 and 300 trophies above the previous league, up to the Legend League, where there is no such threshold; gaps between lower leagues are smaller and vice versa.
On the other hand, demotion occurs when the player drops more than 100 trophies below the limit required to join that division of the league (50 trophies for Bronze League II and I). For example, if you are in Silver II and you drop to 900 trophies, you will be demoted to Silver III. This is to prevent players from changing leagues too often.
Players who fall below 300 trophies (i.e. get demoted from Bronze III) will lose their league ranking until they obtain 400 trophies or more to re-enter Bronze III.
There is no limit to the number of times players can be promoted or demoted during a season.
Each league has 3 separate divisions, except for Legend, which has only one.
Every player in a league gets the privilege to show off their league badge. The badge will appear next to your name in many game areas (e.g. chat, clan, tops, friends list).
You will get a loot bonus for every multiplayer attack victory, including for revenge attacks. The bonus can be seen in the battle result screen and is awarded in addition to the amount of loot that you stole from your opponent.
The loot bonus gained depends on the total damage you have done. In order to get the full loot bonus, you must achieve at least 70% destruction. Destroying any less than that in a victory will award partial loot bonus; for example, 80% of the loot bonus is awarded at 50% destruction.
The leagues are the determining factor of your Star Bonus; higher leagues will offer more loot in the Star Bonus.
Each league will track victories while both attacking and defending. You can see them near your name in the league screen which can be accessed by clicking the trophy icon shown below your current trophy count. The victory counters automatically reset when the season ends or if your trophy count drops under 300 at any time.
You will be grouped with up to 100 players at a time in your league to help you gauge your progress. Each league will track the number of places you move up or down inside your own league group.
When A League Season Ends
All players are removed from their leagues and automatically become "unranked" (Your badge will be replaced with a gray, empty badge).
The placement process will start all over, so complete another multiplayer attack to be placed back into a league. If you don't keep playing, you don't get to keep your badge!
Even if your league level doesn't change, you will get grouped with a completely new set of players within your league once you rejoin it.
League seasons last approximately one month and they reset on the last Monday of each month at Midnight Eastern Time (US). Therefore, each League season will last four or five weeks. You can check to see how much longer the current league season will last by clicking on the trophy icon at the top left of the main screen. The remaining time will be shown below your league level.
Approximately 35% of the seasons will have five weeks.
The Legend League has a special rule that, at the end of a League season, all players in the Legend League whose trophies are more than 5000 will have their trophies reset to 5000, however they acquire prestigious Legend Trophies to make up for the excess Trophies that they lose - purple Trophies that will be permanent in their profile. For example, if at the end of a League season, a player finishes with 5100 trophies, he gets reset back to 5000 trophies and earns 100 Legend Trophies.
Legend League players whose trophy counts drop below 5000 but stays above 4900 (to avoid being demoted) can still see their rankings at the end of the season, but won't gain any Legend Trophies and trophy counts will stay the same.
Leagues were added in the Version 3.124 update on April 17th, 2013.
