To set an admin in a game, the process can vary depending on the game you are playing. Generally, you can try the following steps:
1. Access the game's settings or control panel.
2. Look for the admin or moderation settings.
3. Find the option to add or promote an admin.
4. Enter the username or user ID of the person you want to make admin.
5. Save the settings or apply the changes.
If these steps don't work or if you need specific instructions for a particular game, it would be helpful to provide the name of the game so I can assist you better.
