Register with a real email — score submission requires a confirmed account. Your profile page goes live immediately and starts collecting stats with your very first play.
Two ways to play:
Grab maps from the beatmap library — search by artist, title or mapper, check star rating and BPM before downloading. In the client, osu!direct-style downloads work out of the box on osudesu.

Every pass lands on the map's leaderboard and feeds your PP. Watch your global rank, join a clan for the weekly wars, and keep an eye on seasons — separate ladders with rewards. Curious how PP math works? Read the PP system explainer.
Multiplayer lobbies work in the client like on any server — invite friends who are also connected to osudesu. No friends on the server yet? The leaderboard and Discord are where the community hangs out; spectating and replays make it easy to learn from stronger players.
Completely. No paid ranks, no pay-to-win cosmetics gating gameplay. The server is community-run.
Try the web player first — it runs in your browser and teaches you the rhythm basics on real maps. When it clicks, install the client and connect.
In the client — yes, like anywhere. The web player accepts .osk skin files too.
Same idea as official: performance points per play, summed with decay into your profile PP. We run our own PP ladder per mode, including separate Relax and Autopilot rankings.
