Ask any Roblox player what they grew up on and the answer is usually an obby: a floating obstacle course where you run, jump, fall, respawn, and swear you will make the next platform this time. We wanted that loop with zero installs, so we built Cloud Course, a full 3D obstacle tower that runs right here on this page. It is rendered in WebGL with a blocky avatar, moving platforms, and checkpoints, and a new tower goes up every day. Free, no download, no signup.
Play Cloud Course now
Tap Play, run with the pad, and jump your way to the golden pad at the top. On a keyboard: WASD to run, space to jump, drag the mouse to turn the camera.
How to play
Today’s tower is generated from the date, so every player in the world faces the same 34 platforms today. Red blocks burn the run, yellow pads are checkpoints that save your progress, and sliding platforms need a timed jump. Fall and you respawn at your last checkpoint in under a second, with a fall counter keeping you honest.
The clock starts when you do, and finishing shows your time with your best for today next to it. Your best times, falls, and finish streak are saved on your device, and nothing leaves your browser. A new tower arrives at midnight, which is how streaks grow.
How it compares to Roblox
Cloud Course keeps the feel of a classic Roblox obby: a third-person blocky avatar, platforms floating over a long drop, checkpoints that turn rage into “one more try”, and course design that gets meaner as you climb. Jumps are tuned so every gap is makeable, which means every fall is your fault, and that is exactly the energy an obby should have. Runs take two to five minutes, and chasing a faster time is the real game.
But Roblox is not an obby; it is a platform with millions of games, and that is the part we made no attempt to copy. There is no catalog here, no avatar shop, no chat, no friends list, no creator economy, and no user-made anything. Cloud Course is one hand-tuned course a day, built by us, running entirely on your device.
So when should you get the real thing? If you finish today’s tower twice and want a harder one right now, Roblox has thousands of them, plus every other genre players have built. Our version is a daily espresso; Roblox is the whole cafe.

Frequently asked questions
Can I play Roblox in a browser?
Roblox is browsed on the web, but actually playing requires installing the Roblox app or player on your device. Cloud Course, the game on this page, is our own original obby that runs entirely in the browser on phone or desktop, so it works even where installs are blocked.
Is this the real Roblox?
No. Cloud Course is an original game we built, inspired by the obby genre that Roblox players made famous. It is not affiliated with, endorsed by, or connected to Roblox Corporation in any way. All art and sound are our own code, and the download links above point to the official app.
What is an obby?
Obby is Roblox slang for obstacle course: a chain of platforms, hazards, and checkpoints between spawn and the finish. It is the genre most players start with because the rules fit in one sentence. Ours adds a daily seed, so the course changes every day but is identical for everyone.
Is it free?
Completely. No ads, no purchases, no account, and no data collection. Your times and streak live in your browser’s local storage and are never sent anywhere.
Does it work offline?
Once the page has loaded, the game makes no further network requests, so it keeps working through connection drops. Roblox itself always needs a connection, since every game on it is streamed from its servers.
