How to Invite People to osu! Multiplayer: A Complete Guide
osu! is one of the most popular rhythm games on PC, and its multiplayer mode transforms a solo experience into something genuinely social. Whether you want to play against friends or challenge strangers, knowing how to set up and invite others to a multiplayer lobby is the first step. The process is straightforward once you understand how the system is structured — but a few variables can affect how smoothly it goes.
How osu! Multiplayer Works
osu! multiplayer runs through the game's built-in online infrastructure. When you create a multiplayer lobby, you're hosting a room that other players can join either by direct invite or by finding it listed in the public lobby browser. There are two main multiplayer frameworks in osu! depending on which version of the game you're running:
- osu! (Stable) — the classic client, which has been around for years and uses the traditional lobby system
- osu!(lazer) — the newer, actively developed client with an updated multiplayer interface, including a Playlists mode alongside the classic free-for-all rooms
Both clients support inviting friends, but the interface and steps differ slightly.
Step-by-Step: Inviting Friends on osu! Stable
1. Log In and Go Online
Make sure you're logged into your account and your status is set to online (not "do not disturb"). Players set to offline mode cannot access multiplayer features.
2. Open the Multiplayer Lobby
From the main menu, click Play, then select Multi. This opens the lobby browser. You can either join an existing room or click New Game to create your own.
3. Set Up Your Room
When creating a room, you'll configure:
- Room name — visible to other players if the room is public
- Password — optional, but useful if you only want specific friends to join
- Game settings — map, mods, win conditions, team mode
4. Invite Friends Directly
Once you're inside the room, open your Friends list or click on a player's username in the chat panel. From there, select Invite to Game. This sends them a notification in the game chat with a clickable link to join your lobby.
🎮 Your friend must be online and in the game to receive and act on the invite. Invites don't carry over if they're offline.
5. Share the Room Link (Alternative Method)
Inside an active room, there's typically a link or room ID visible in the chat. You can copy and share this in osu!'s in-game chat, through Discord, or other messaging platforms. Friends can paste the link to join directly, provided the room is either public or they have the password.
Step-by-Step: Inviting Friends on osu!(lazer)
osu!(lazer) has a redesigned social and multiplayer interface. The core invite mechanic works similarly:
- Go to the Multiplayer section from the main menu
- Create a room and configure your settings — lazer offers both Head-to-Head and Team VS modes, plus Playlists for asynchronous competition
- Once inside the room, open the player list panel
- Click the Invite button or select a friend from your friends list to send a direct invite
Lazer also integrates more tightly with the osu! website's social features, so your friends list is synced with your account across both clients.
Key Variables That Affect the Invite Process
Not everyone's experience looks the same. Several factors shape how this works in practice:
| Variable | Why It Matters |
|---|---|
| Client version | Stable vs. lazer have different UIs and slightly different invite flows |
| Online status | Both host and invitee must be online in-game for invites to work |
| Friends list status | You can only send direct in-game invites to users on your friends list |
| Room visibility | Public rooms can be found in the browser; private rooms need a password or direct link |
| Network/firewall settings | Some network configurations can cause connection issues when joining lobbies |
Inviting Players Who Aren't on Your Friends List
If you want to play with someone who isn't on your friends list yet, the typical approach is:
- Add them as a friend through their profile page (in-game or on the osu! website)
- Wait for them to accept or add you back
- Then use the standard in-game invite
Alternatively, share your room link externally — via Discord, social media, or a message — so they can join without needing a formal friend connection. A room password keeps the lobby private while still letting targeted people in.
When Invites Don't Work
A few common reasons invites fail or don't reach the other person:
- The recipient is offline or in "Do Not Disturb" mode
- They're already in another multiplayer room
- The room has reached its player limit (osu! rooms support up to 16 players)
- A network issue is preventing the lobby connection from completing
- The invite was sent but missed in chat — osu!'s in-game chat moves quickly in busy lobbies
In most cases, sharing a direct room link through an external chat app is the most reliable backup.
Understanding the Difference Between Room Types 🎵
osu!(lazer) introduced Playlists, which work differently from traditional multiplayer rooms. In a Playlist, the host queues up specific maps and mods, and players compete asynchronously — they don't need to be online at the same time. This changes the invite dynamic: rather than joining a live session, players join the Playlist and submit scores on their own schedule.
Traditional multiplayer rooms in both clients are synchronous — everyone plays together in real time, and the host controls the flow of the session.
The right setup depends on whether your group wants a live, simultaneous session or a more flexible asynchronous competition. Your friends' schedules, time zones, and how competitive you want the experience to feel all factor into which mode actually fits the situation.
