Clubs are places where you can gather with other players and achieve awesome things!
You can either create a new club or join one which is already created by another player. All clubs can have 30 players maximum and they can be set as public or invitation only. The preferred language, level and club badge are set by the leader. Be sure to add a clear description to your club to attract players' attention!
After you join the club, you will be able to participate in the Tournaments. Each member of the Cafe Club will get a list of tasks, and they'll try to complete them in time and make the most contribution to their club. At the end of each Tournament Season participants get rewards according to their contributions! More info can be found under the Leagues help article.
Also, members of the Clubs can chat with each other, can ask for help with certain tasks.
