To join someone’s game in Roblox, start by ensuring your settings are correct. Open the Roblox app, click the three dots at the bottom, then the gear icon. In the privacy settings, make sure “who can join me in experiences” is set to “friends” to allow your friends to join you.
If you want to join a friend’s game, find the friend you want to join from your friends list on the Roblox app. Tap on their avatar, and if they’re currently playing, a green “Join” button will appear. Tap this button to join their game immediately.
To join someone who isn’t on your friends list, visit the Roblox website and search for their username. Go to their profile, and if they are playing a game, you will see a “Join” button. Click this to join their game directly.
Another method is using the “Rosearcher” Chrome extension, which allows you to join someone’s game without being friends. Copy the game ID from the URL and paste it into the extension to join their server. Note that some users might have settings that prevent non-friends from joining their games.
