Team War Seasons are campaigns that last for 60 days. At the end of the season, players are rewarded based on their league position and their trophies are adjusted.

During each Season, players must participate (i.e. attack at least once) in at least 10 Wars with the team they end the season with. Players who leave a team will have their counter reset.

There is a 3-day "Off-Season" period between Seasons to allow the wars started in the previous Season to finish and to calculate the Season's final score. During the Off-Season, teams won't earn Trophies, but they will still earn War Coins and War Medals.
