Even King Robert knows you can’t run a kingdom alone. Band together with your team this weekend for the Team Battle, crush levels to pick up shields, outshine rival teams and bring home a victory chest full of gold and boosters.

Quick take: Victory is best when shared. Join forces with your teammates to compete against 19 other teams to collect as many shields as possible. Team rankings are based on the total number of shields each team member collects. The top five teams at the end of the event receive rewards based on their rank. A team can take part in the battle once one of its members beats a level. Be sure to stick to your team though. If you change sides during the event, you won’t get rewards.

When it’s happening: Team Battle takes place biweekly over weekends, from Friday to Monday.
