Clubs are unlocked once a player has reached XP level 15. Navigate to the clubs area by tapping on the Clubs tab at the bottom of the screen.

Here you can search for a club or scroll through the list of club names. Clubs can have a maximum of 20 players and the member count is displayed to the right.

Tap on a club name to see its description, language, members, and to join. Public clubs will have a “Join club” button and private clubs will have a “Request to join” button. You will not be able to join or request to join a club that is full.
