I still remember the first time I switched from solo Terraria to multiplayer: I’d spent 20 hours grinding for Hellstone bars alone, only to join my cousin’s world and knock out the Eye of Cthulhu in 10 minutes flat with three other players. If you’ve only ever explored Terraria’s biomes by yourself, you’re missing out on half the fun of the game. If you’re asking how do you play multiplayer on Terraria, this guide breaks down every step for PC, console, and mobile, plus fixes for the most annoying connection issues I’ve run into over 10 years of playing.
How Do You Play Multiplayer on Terraria Across Different Devices?
If you’re still figuring out how do you play multiplayer on Terraria for your specific device, follow these simple steps for each major platform. For Steam PC users, open the game and select “Multiplayer” from the main menu. You can either choose “Host & Play” to create your own world, select your privacy settings and password, then invite friends directly through the Steam overlay, or “Join” to connect to a friend’s open lobby or enter a server IP address. Always double check that everyone in your group has the same game version installed – even a small hotfix mismatch will prevent you from joining the same lobby.
For console players (PlayStation, Xbox, Nintendo Switch), you’ll first need an active online subscription for your platform to access multiplayer. Once you’re signed in, select “Multiplayer” from the main menu, choose to host or join a world, and send invites through your console’s native friend list. Crossplay is supported across all modern platforms as of the latest 1.4.4 update, so you can play with friends on different devices as long as everyone is on the same game version. For mobile players, you can either connect to local lobbies on the same wifi network, or use online multiplayer to invite friends through Google Play Games or Apple Game Center.
Key Differences Between Public, Private, and Dedicated Terraria Servers
Not all multiplayer lobbies work the same, and picking the right type for your group will save you a lot of hassle later. The simplest option is a private host & play lobby, which you can launch directly from your game in 30 seconds. It works great for casual 2-4 player sessions, but the world will shut down as soon as the host leaves the game. Public lobbies are open to any player searching for games, which is perfect if you want to meet new Terraria fans or join a pre-built world with progression already underway. You run the risk of running into griefers who will destroy your builds or steal your loot if you host a public lobby without restrictions, though.
For long-term playthroughs, dedicated servers are the best option. These run independently of any player’s game, so the world stays online 24/7 even if no one is logged in. You can set custom permissions, add mod packs, and support up to 16 players at once, but you’ll either need to run the server on a spare home PC or pay for a third-party server host. You can pick the right server type for your needs using this quick breakdown:
- Pick a private host & play lobby if you’re only playing for 2-3 hours with 2-4 close friends, and don’t care about keeping the world online when you’re done.
- Pick a public lobby if you want to meet new players, test new builds with a community, or join a pre-made world with progression already done.
- Pick a dedicated server if you’re running a long-term playthrough with 8+ players, or want the world to stay online 24/7 for anyone to drop in anytime.
If you’re planning to play modded Terraria with a group, dedicated servers are non-negotiable for smooth performance. Dedicated servers are the only option if you want to use large mod packs like Calamity with a large group – hosting a modded world via standard host & play will cause extreme lag for everyone connected, and will often crash mid-boss fight.
Common Terraria Multiplayer Issues and Simple Fixes
I’ve run into almost every Terraria connection issue imaginable over the years, and most of them have a quick, easy fix you can do in 2 minutes. The most common error is “Lost connection to host”, which 9 times out of 10 is caused by a version mismatch between players. If everyone is on the same version, ask the host to make sure they have port 7777 (the default Terraria server port) forwarded on their router if they’re not using Steam or console native lobbies. If you’re getting constant lag spikes while playing, first ask the host to close any background apps that use bandwidth, like streaming services or cloud file backups.
If you’re the one joining the lobby, switch to a wired internet connection if possible, as wifi can cause random lag spikes during boss fights which is the worst possible time to freeze. If you can’t see a friend’s lobby in the search menu, first make sure both of you have your online status set to visible on your platform, and that the lobby is set to “Friends only” instead of “Invite only”. If that still doesn’t work, send a direct invite through your platform’s friend list instead of searching for the lobby in-game. For modded playthroughs, make sure every player has exactly the same mods installed with the same versions, even small cosmetic mods will cause connection errors if one player is missing them.
Best Practices for Fun, Safe Terraria Multiplayer Sessions
A little bit of prep before you start playing will make your multiplayer sessions way more enjoyable for everyone. If you’re hosting a public lobby, always turn on spawn protection to stop new players from destroying your base as soon as they join, and set a password if you only want people you invite to be able to join. Griefing is far more common than many new players expect, and losing a build you spent 50 hours working on is a terrible feeling. Before you start a new playthrough with a group, agree on basic progression rules first: for example, no beating the Wall of Flesh until everyone has made their pre-Hardmode gear, and no taking rare items from community chests without asking. I once joined a group where someone beat the Moon Lord without telling anyone, and we all lost the chance to experience the final boss fight together, which completely killed the playthrough for most of us.
Make regular backup saves of your multiplayer world – even if you don’t run into griefers, game crashes or power outages can corrupt world files, and you don’t want to lose weeks of progress. If you’re playing with younger players, turn on the in-game chat filter, and only let them join private lobbies with people you know. You can also set player permissions to stop new players from breaking blocks or opening chests until you’ve verified they’re not there to cause trouble.
Playing Terraria with friends turns an already great sandbox game into an endless source of inside jokes, chaotic boss fights, and builds you could never make alone. Whether you're setting up a quick lobby for a Saturday afternoon playthrough or a dedicated server for a year-long modded run, now you know the answer to how do you play multiplayer on Terraria. The next time you log on, send an invite to a friend – you won't regret it.
