Player-run stalls line the main routes, making it the fastest place to sell materials and buy gear. - Spawn: The default arrival point for new players, and the main orientation area. Orientation markers and the first set of directions are found here. ## FAQ ### Is Unstable SMP a public Minecraft server? Yes. Unstable SMP is a public Minecraft survival multiplayer (SMP) server.

Open Minecraft Java Edition, click Multiplayer, click Add Server, and enter unstablesmp.io. No port is needed. ### How do I join Unstable SMP on Java Edition? Open Minecraft Java Edition, click Multiplayer, click Add Server, then enter unstablesmp.io as the server address and join. Do not add a port unless Minecraft explicitly asks for one. ### Does Unstable SMP support Bedrock Edition? No. Unstable SMP runs on Minecraft Java Edition only. Bedrock Edition is not supported and there is no Bedrock port. Play on PC, Mac or Linux. ### Can I join Unstable SMP on cracked Minecraft? No. Unstable SMP requires a legitimate, purchased Minecraft account. Cracked launchers, shared accounts and stolen credentials are not allowed and result in a permanent ban. ### What Minecraft version does Unstable SMP support? The live server advertises 1.21.1+ for Java and Paper 26.3 server software. Unstable SMP usually runs several versions at once through its proxy, so check the current announcement in Discord if your client is refused. ### How many players can join Unstable SMP at once? The server slot count is 14,000 players. The live count is shown on this site and updates automatically from the server status feed. ### Are hacked clients allowed on Unstable SMP? No. KillAura, reach, ESP and other cheat clients are banned. Limited, non-cheat optimisation mods such as Sodium, Lithium and Fabric API are allowed. See the full Unstable SMP rules for the exact list. ### Is PvP allowed on Unstable SMP? Yes. PvP is allowed on the server. Dupes, exploits, unfair combat mods and griefing are not. Fights follow normal Minecraft PvP conventions. ### Which YouTubers play on Unstable SMP? Wemmbu, FlameFrags, ParrotX2 and Spoke all make official Unstable SMP content.

The website and the Discord are the only official sources. ### How do I get support for an Unstable SMP issue? Open a ticket in the Discord, or email support@unstablesmp.io. Include your Minecraft username, your client version and the exact error message so the issue can be identified quickly. ### Is Unstable SMP the same as the Unstable Universe YouTube series? They are related but different things. The Unstable Universe is a scripted Minecraft video series made by ParrotX2, Wemmbu and Spoke. Unstable SMP is the public survival server that Unstable SMP runs, which those creators and many others play on. If you are looking for a server IP to join, it is unstablesmp.io. If you are looking for the episodes, they are on YouTube. ### Why do some sites say Unstable SMP has Bedrock support? They are out of date or wrong. Unstable SMP has never run a Bedrock listener, so Bedrock Edition, console and mobile cannot connect and no Bedrock port exists. Several other websites claim an address for Unstable SMP with a Bedrock port; those are separate servers and the port will not connect. The only address for this server is unstablesmp.io. ### How many players are on Unstable SMP right now? Around 14,000 slots, with roughly 8,000 players online at peak. The live count is on the Unstable SMP website and reads directly from the server, so it is never out of date. ## Notes Unstable SMP is not affiliated with Mojang AB or Microsoft Corporation. Minecraft is a trademark of Mojang AB. The address unstablesmp.io is the only official Unstable SMP server address; lookalike domains and other websites using the name "Unstable SMP" are not this server.
