Multiplayer · no server needed
Someone opens their singleplayer world, everyone else drops in. The host's browser is the server, so players connect straight to it. Nothing to rent, install or configure.
In the game, press Esc → Invite → Start shared world, on the MinePlay relay that is already in your list.
Your world appears below with its five-character code already filled in. One click puts it on the public list — and on the map on the home page.
They press Join and drop straight into your world. Nothing to install, no server to rent, no port forwarding.
Relay offline
Open a world to the relay in-game and publish it here so other players can find it. Sign in first, so the listing is tied to your account and only you can take it down.
Sign in to publishA shared world is a normal singleplayer world that the host has opened up. Their browser keeps running the world and every player who joins connects directly to them, peer to peer. MinePlay's relay only introduces the two sides — it never carries the game itself.
Three consequences worth knowing before you host:
Close the tab and the world closes with it: everyone is disconnected and the join code stops working. Nothing is lost — the world is saved in the host's browser and backed up to their account — but it has to be the same player who opens it again.
Each time a world is opened it gets a fresh five-character code, so never bookmark one. Bookmark this page instead; it always shows what is actually live.
That is how peer-to-peer works, here and in every other WebRTC game. If it matters to you, host for people you know and leave the world unlisted — the code still works.
Press Join on any world above and we open the right client with the code ready. In-game, go to Multiplayer → Direct Connect → Join Shared World, paste the code, and you are in.
Both players need the same relay in their client. MinePlay adds ours automatically — if you play elsewhere too, add the address below under Multiplayer → Network Settings → Add Relay.
A shared world is perfect for an evening with a few friends. If you want a world that stays up while you sleep and holds dozens of players, that is a dedicated server — a machine running EaglerXServer somewhere. MinePlay lists those too, but does not host them.
