To join a clan in Clash of Clans, start by rebuilding your Clan Castle. Tap on the abandoned Clan Castle in your village and choose “Rebuild.” This will cost you 10,000 gold, so make sure you have enough by reaching Town Hall level 3 and upgrading your storages.
Next, open the Clash of Clans app and tap the profile button in the upper-left corner. Select “Clans” from the menu. You can now search for a specific clan by typing its name in the search bar. If you don’t have a specific clan in mind, browse through the available options.
Before sending a join request, review the clan’s requirements to ensure you meet them. Tap “Join” and write a brief message explaining why you want to join. Send your request to the clan leader for review.
After you send your join request, wait for the clan leader to approve it. They will decide whether to accept you into the clan. Keep in mind, you can only belong to one clan at a time. If you wish to join a different clan, you must leave your current one first.
