How can I change my username in Clash Royale?

Changing your username in Clash Royale is a straightforward process. First, one must open the game and navigate to the settings menu, usually symbolized by a gear icon. Within the settings, there's an option to change the username. Typically, the first change is free, but subsequent changes may require spending gems, the in-game currency. It's important to choose a new name wisely since it represents your identity in the game, and frequent changes can become costly due to the gem requirement. Once you have decided on the new username and confirmed it satisfies all of Clash Royale's guidelines, you can finalize the change and your new username will be displayed in-game.
