Play Osu Mania Online: The Ultimate 4-Key Rhythm Challenge

Master the rhythm in Osu Mania, a faithful 4-key rhythm game adaptation you can play for free online. Hit the falling notes with perfect timing using the D, F, J, and K keys, holding down for extended slider notes. Customize your controls or instantly exit any map with the P key for a personalized experience.

Deep Customization & Personalization

This online version shines with extensive customization. Personalize your playfield with 16 vibrant note colors, each defined by precise RGB codes like deep blue (135, 206, 235) or rose pink (245, 176, 65). The true power lies in importing your own content. Follow our detailed guide to add any 4K osu!mania beatmap from the official game: prepare your .osu file, use the external text tool to format it correctly, then import your chosen music and background image.

Create Your Unique Skin

Go beyond the default look by fully reskinning the game. Edit the note and receptor sprites directly, or import assets from your favorite osu! skins to create a truly unique visual experience. Whether you're practicing popular charts, testing your own custom creations, or enjoying a fresh visual style, Osu Mania delivers an authentic, flexible, and deep rhythm game experience directly in your web browser.
