The differences between open, private and closed clubs are as follows:

• Public club - Joining is completely free and anyone can be invited.
• Private club - Every player must send an invitation to the respective club. Every request to join is reviewed by the club leader, who has the right to accept, reject or ignore it.
• Closed club - A player can join this type of club after receiving an invitation from the club itself. The player can send a message to the leader requesting an invitation.
