World: Keep of the Green Hill · Built by corbin · 1,284 visits today
KUBIX is a place where everything you see was built by somebody out of blocks — castles, obstacle courses, race tracks, whole towns. Play what other people made, or open the builder and make your own. Nothing costs anything to start.
Thousands of worlds, made by people like you. Jump straight in from the browser — no waiting around for a download.
Drag blocks, paint them, wire them up with scripts. The same tools that made every world on the front page.
Add friends, join their servers, and build side by side. Chat is filtered and every world can be reported.
A few of the worlds people are in today.
KUBIX Studio is the builder. Place blocks, paint them, give them behaviour, then publish — your world gets its own page and anybody can join it. It runs on the same computer you play on.
One account, everywhere. Pick your thing up where you left it.
Preview. This is what the signed-in home looks like — nothing here is saved, and the numbers are made up.

Any picture you like. It gets cut to a square and shrunk to 320×320 before it goes anywhere, so a photo off your phone lands around 20 KB.
You're on an older build.
That part of KUBIX isn't finished.
