What is the Club Battle?

Club Battle is a time-limited event where your club competes against 19 other clubs.
During the competition, you collect scores after beating levels, and your club ranks up based on the total number of shields all the club members collect.
When the Club Battle ends, you receive a reward based on your club's rank. Each club member gets the same reward if your club is among the top five.
You can see your club's ranking by tapping the Club Battle icon on the home screen.
You can also see each club member's contribution from the "My club" tab in the Club Battle screen.
club members are ranked based on their contribution to the club score during the event, and the top 3 club members get additional rewards.
Every Club Battle event is separate. You cannot transfer your scores to the following Club Battle events.
You collect extra scores from Hard and Super Hard levels.
