The fastest way to join a friend in Roblox

To join someone in Roblox, open the game, find your friend's name in your Friends list, and click the Join Game button next to their name. This works only if they are currently playing a game — if they are in the main menu or offline, the button will not appear. The game will load and place you in the same server as your friend within a few seconds.

If you do not see a Join Game button, your friend may have turned off the ability for others to join them, or they may be playing a game that does not allow mid-game joining. Some Roblox games have settings that prevent new players from entering once the game has started.

Key Takeaways

  • The Join Game button appears next to your friend's name in the Friends list only when they are actively playing a game.
  • Some games do not allow new players to join mid-game, so you may need to wait for the current round to end or restart.
  • If your friend has disabled joining, you can ask them to turn it back on in their game settings or privacy options.
  • You can also join through the game's main page by clicking the Play button and hoping the server places you together, though this is less reliable than using the Join Game button.

Finding the Join Game button in your Friends list

Open Roblox and look at the left side of the screen. Click the Friends icon (it looks like two people). Your Friends list will show all the people you follow. Scroll through the list until you find the person you want to join.

Next to their name, you will see what they are doing. If they are playing a game, a Join Game button will appear in green. Click it. If the button is grayed out or missing, they are not in a game right now — they may be in the main menu, browsing, or offline.

What to do if the Join Game button is not there

If you see your friend's name but no Join Game button, they are either not playing a game or they have turned off joining. Ask them directly which it is. If they want to play with you, they can start a game and then you can join using the button.

Some players turn off joining to play solo or to keep their server private. Your friend can turn this back on by going into their game settings. The exact location depends on which game they are playing, but most games have a privacy or settings menu where they can allow or block joiners.

Joining through a game's main page

Another way to play together is to go to the game's main page on Roblox, click the Play button, and hope the game puts you on the same server as your friend. This method is not reliable — the game may place you on a different server entirely. You will then need to leave and try again, or ask your friend which server they are on if the game shows server names.

This approach works better in games that have fewer active servers or games where your friend can tell you exactly which server they joined. Some games show a list of servers you can pick from; if yours does, ask your friend which one they are in and join that one directly.

When a game does not allow mid-game joining

Some Roblox games are built so that new players cannot join once a round has started. This is common in competitive games, games with limited player slots, or games where the round structure matters. If you try to join and get a message saying the game is full or not accepting new players, you will need to wait.

Ask your friend when the current round or game will end. Once it does, you should be able to join them. If the game keeps rejecting you, it may not support mid-game joining at all — in that case, you and your friend will need to start a fresh game together by both clicking Play at the same time and hoping you land on the same server.

Troubleshooting when joining does not work

If you click Join Game and the game does not load, or you load into a different server than your friend, try these steps: First, make sure your internet connection is stable. Second, close the game completely and try joining again. Third, restart the Roblox app or refresh the browser if you are playing on web.

If you keep landing on different servers, the game may have multiple servers running and the system is not placing you together. In this case, ask your friend to leave the game and rejoin, then you join immediately after. Sometimes this forces you onto the same server. If nothing works, you may need to try a different game or come back and try later when fewer people are playing.

Making sure your friend can join you

If you want your friend to be able to join you, make sure joining is turned on in your game settings. The location of this setting varies by game, but it is usually in a menu labeled Settings, Options, or Privacy. Look for a toggle or checkbox that says something like "Allow others to join" or "Allow joiners."

Once you turn this on, your friend will see the Join Game button next to your name in their Friends list. Keep in mind that some games override this setting — if the game is full or does not support mid-game joining, your friend still will not be able to join even if you have it turned on.

Frequently Asked Questions

Why does the Join Game button say my friend is playing but I cannot join?

The game they are in may not allow new players to join mid-round, or the server may be full. Ask your friend if the game has a waiting period or if they need to finish the current round first. Some games also have a maximum player count that prevents new joiners.

Can I join my friend if they are playing on mobile and I am on computer?

Yes. Roblox games work across devices, and the Join Game button works the same way whether your friend is on mobile, computer, or console. You will join the same server and play together normally.

What if my friend turned off joining and I want to play with them?

Ask them to turn joining back on in their game settings, or ask them to leave the game and start a new one with you. Once they start a fresh game with joining enabled, you can use the Join Game button to enter.

Does it cost Robux to join someone's game?

No. Joining a friend's game is always free. You only spend Robux if the game itself charges for entry or if you buy items inside the game.

Can I join my friend if they are in a private server?

Only if your friend has invited you to that private server. Private servers are separate from regular public servers, and the Join Game button will not work for them. Your friend must send you an invite link or add you to the private server's access list first.
