The requirement depends entirely on which platform you're playing on:
| Platform | Online Multiplayer Requirement | Offline / Local Play |
|---|---|---|
| Xbox One / Series X|S | Yes – Xbox Game Pass Core (formerly Gold) required | Free (single-player, splitscreen) |
| Windows 10/11 (Bedrock/Store) | No (uses Xbox Live account, but no paid sub) | Free |
| Java Edition (PC/Mac/Linux) | No (uses Mojang/Microsoft account) | Free |
| PlayStation 4/5 | PlayStation Plus required | Free |
| Nintendo Switch | Nintendo Switch Online required | Free |
| Mobile (iOS/Android) | No (Microsoft account only) | Free |
Bottom Line: Only Xbox consoles mandate a paid subscription (Game Pass Core, ~$10/mo or $60/yr) for online Minecraft. Every other platform uses its own ecosystem's online service or none at all.
