Can you play MU Online in the browser? Yes, with no download

Yes, you can play MU Online in the browser. Idle MU is a MU Online Season 6 Episode 3 server where the game opens in a Chrome or Edge tab. It is not a game "inspired" by MU: it is the original client, with the same graphics, maps, classes, events and keys, running inside the browser.

You click Play, the MU login screen shows up and the rest is the game you already know.

What you need

	Status
Chrome or Edge on Windows and Mac	Works.
Chrome or Edge on Linux	Works after turning on one setting.
Firefox	Not recommended. Use Chrome or Edge.
Phone and tablet	Not available.

The step-by-step for each browser is in First steps.

How to start

Create your account. It is just a username and password, with no email confirmation.
Click Play now. The first time, the browser downloads about 80 MB; after that, it opens in seconds.
Pick the channel, create your character and start in Lorencia.

What is the same as the MU you know

The five classic classes: Dark Knight, Dark Wizard, Fairy Elf, Magic Gladiator and Dark Lord.
Level 400, Master Level and reset.
Blood Castle, Devil Square, Chaos Castle and the invasions, at the server's times.
Auto farm with Idle, which keeps hunting with the tab minimized.
The keys, shortcuts and commands you already know by heart.

Frequently asked questions

Do I need to install anything?

No. There is no client, no launcher and no extension. The game runs right in the browser tab.

Does it work in any browser?

It works in Chrome and Edge, on Windows and Mac, with nothing to configure. On Linux you need to turn on one Chrome setting. Firefox is not recommended.

Can I play on my phone?

No. The game uses a mouse and keyboard. The rest of the site, like the ranking, the dashboard and the shop, works on a phone.

Is this the official MU Online?

No. Idle MU is an independent server, with no ties to Webzen, the owner of the MU Online brand.
