Free to playMcOsu Rhythm training with no ceiling
Hit circles to the music at whatever speed, size and difficulty you set, in flat screen or VR.
Is McOsu worth it?
McOsu is worth it if…
- you already play osu! and want tools stable does not offer
- you keep failing the same section of a map and want to drill it in isolation
- you want to lower a map's difficulty and feel unstoppable for an evening
- you have a VR headset and want rhythm circles around you instead of on a screen
- you like tinkering with settings, console commands and skins more than following rules

Practice tools that osu! never gave you
The point of McOsu is focused practice, and the tools show it. Hit a section that keeps killing your combo? Scrub to it, quicksave, and reload it as many times as you like. A map too fast today? Drag the speed and BPM slider down, learn the patterns, then push it back up. You can override approach rate, circle size, overall difficulty and HP drain on any beatmap, so you can train exactly the skill that is holding you back: tighter aim, faster reading, or surviving drain. Change mods and options mid-play without leaving the map. There is a live pp counter too, so you can watch the numbers climb while you grind. One honest limit: no replay system, so you cannot rewatch your own runs to spot mistakes.
Break the game on purpose
Beyond straight practice, McOsu is a sandbox. Experimental mods flip the playfield, reverse sliders, or turn circles into a jigsaw of chaos, and you can stack them however you like. The console (SHIFT + F1) opens up options that go well beyond a settings menu. Two modes stand out: a VR gamemode, and FPoSu, a first-person 3D mode where you aim at circles from inside the field. The look is clean and pared back: circles, hit sounds, and whatever skin you choose. Nothing on screen that does not need to be there.
What do I need to play it?
Do you need osu! installed to get beatmaps?
Not strictly. If osu! (stable) is installed, McOsu loads your beatmaps straight from it, which is the easy path. You can also run McOsu on its own and manage beatmaps manually, with a guide in the Steam Community Guides, or use third-party beatmap mirrors. No official osu! account is needed. Note that only osu! standard beatmaps work: mania, taiko and catch diffs simply do not show up.
Can you play it solo?
Yes, and only that. McOsu is a singleplayer client with no online multiplayer or leaderboards, just local rankings on your own profiles. It is built for practicing and messing around on your own terms, not competing with others.
Is it good for rhythm game beginners?
Honestly, no. There are no gameplay tutorials here, and the developer says outright that new players should start with the official osu! instead, which is more polished and has online rankings. McOsu assumes you already know how circle-clicking works and want to practice it your way. The exception is VR and FPoSu players, who can enjoy it without any osu! background.
