Why Not Just Host on a Phone?
The mobile app can host a multiplayer world itself, and for a quick session on the same Wi-Fi that works fine. The trouble starts when a group wants a shared world it can visit on its own schedule. The world only exists while the host's app is open, a call or a locked screen can drop everyone, and the host's phone does all the work, which costs battery and heat.
A dedicated server takes those problems away. The world sits on a machine in a data centre, online all day, and every player connects to it the same way. Nobody needs to be the host, nobody gets the host's advantage, and a lost or reset phone no longer means a lost world.
- Always available: log in for ten minutes on the bus or three hours at the weekend.
- Internet play: friends join from anywhere, not only on one Wi-Fi network.
- Safe world: offsite backups instead of a single phone's storage.
- Admin tools: passwords, kicks and bans from the server console.
Who Can Join: iOS, Android, PC and Consoles
Mobile Terraria is made by DR Studios and published by 505 Games for iPhone and iPad, Android through Google Play, and Fire OS through the Amazon Appstore. The official wiki notes that iOS and Android players can play multiplayer together, so a mixed group of phones is no problem.
PC is the interesting part. Re-Logic's February 2026 State of the Game says desktop and mobile can already play together through a dedicated server, because the two versions now share the same game code and version numbers. In practice a friend on Steam can join your mobile group's server as long as their game is on the same build. Consoles are the missing piece: crossplay for them is planned as part of the 1.4.6 update, which Re-Logic has not dated.
How Many Slots a Mobile Group Needs
Terraria plays well with a handful of friends, and most mobile groups are small. Our slider sells 10 to 16 slots; buy for the most people you expect online at once, not the total number who might ever join.
| Group | Suggested slots | Memory on that plan |
|---|---|---|
| A group of friends | 10 | 5GB |
| Friends with regular guests | 12 | 5GB |
| A small community or class | 16 | 8GB |
Expert and Master modes scale boss health with the number of players in the fight, so a bigger group does not make bosses trivial. If your group grows past 16 or wants mods, our PC Terraria product is the better fit.
Creating a World or Uploading Your Own
You can let the server create a fresh world or bring one you already play on your phone. A new world is set up in the server config: size, difficulty and, if you like, a seed. Difficulty matters most, because Journey, Classic, Expert and Master change how the whole playthrough feels and are fixed when the world is made.
- Stop the server in the panel.
- For a new world, set the size, difficulty and an optional seed in the server config.
- To use an existing world, copy its .wld file from your device and upload it to the worlds folder.
- Set a server password and a message of the day.
- Start the server and join from the app to check everything loaded.
Keeping Versions Matched
Version mismatch is the one thing that stops a mobile group connecting. Mobile Terraria reached the 1.4.5 content on 5 February 2026 and caught up to desktop 1.4.5.8 on 3 September 2026, with hotfix 1.4.5.8.1 on 17 September fixing reconnection after a network drop and several host-related multiplayer bugs.
When a new mobile update lands, have everyone update the app from their store before the next session, and check the server is on the matching build. Re-Logic usually updates the desktop server first, and mobile can follow some weeks later, so for a short time the right server version may be the one before the newest. If you are unsure, open a ticket and we will check it against your app.
Running the World Day to Day
Terraria's server console has the commands an admin needs: list who is online, save the world, kick or ban a player and change the password. Use a password on any server shared beyond your close friends, and change it if someone leaves the group on bad terms.
Take a snapshot before big moments such as defeating the Wall of Flesh, which turns the world to hardmode for good, or before trying a risky build project. We also keep offsite copies of the last 7 days, so a griefer or an accidental lava flood can be undone from the panel. A daily restart at a quiet hour keeps the server fresh for the next evening.
