Leagues create a fun competitive environment that allows you and your club to win some awesome in-game bonus rewards! In order to compete, simply join a club and attack others. You and your clubs' total trophies earned will be tallied up. The team in each league with the most trophies, when the timer runs out, will receive their bonus rewards (in-game rewards will also be given to 2nd-30th place). Rewards vary depending on your place in the league and also the tier of your current league. (Champion II, Champion I, Diamond II, Diamond I, Gold II, Gold I, Silver II, Silver I, Bronze II, and Bronze I).
 
Please note:
The in-game rewards you can collect will be gold, gems, and dice.
