Downloads
It's free. The quickest way is one click on Melty. Already have a launcher you like? Pick it below.
Mineblox Royale is a mod for Minecraft: Java Edition, not a standalone game. Minecraft: Java Edition, Roblox and Fortnite must all be installed on your computer for it to work as intended.
Mineblox Royale only reads a few files from your own copies of Roblox and Fortnite. It never changes, starts or connects to them, and nothing from them is included in the download.
Melty installs Minecraft 26.3, Fabric and Mineblox Royale for you, then starts the game. Just sign in with your Minecraft account, with Roblox and Fortnite installed on your PC too.
Or pick your launcher
Each button downloads the newest version straight from GitHub. Not sure which to pick? The Prism Launcher one has everything inside, so there's nothing else to install.

mods and minebloxroyale folders into it.Good to know
Your launcher first downloads Minecraft 26.3 from Mojang (about 500 MB, once). Leave its progress window open until the game appears.
The game then opens straight into your own Mineblox Royale world. Your first island is made in the background over the first few minutes (the hub shows how far along it is), and the obby, the shooting range and the Locker are open meanwhile.
On Melty, updates come by themselves. With a launcher, import the new version's file the same way you did the first time. Your unlocks and outfit come along.
Everyone who plays together needs the same version.
Every match is played on a new island, and the ones you've finished with are removed when the world opens, so the world folder stays small. With less than 1 GB free, the next match reuses the same island.
Playing together
Everyone starts in their own world. Share a room code and your friends drop into yours. No servers, no port forwarding.
