Ritsudo

Three lanes, three keys and the music you actually listen to. Ritsudo analyzes each song and places the notes so you play the rhythm you hear.

Any song, five difficulties

Drop in MP3, OGG or WAV files, osu! beatmaps or a whole osu! Songs folder. Ritsudo analyzes the tempo, beats, sections, melody and energy of each song and builds five maps, from Easy to Expert. Calm verses give you room to breathe, choruses get denser, and long notes follow the sounds that hold.

Works with audio files on your computer, not streaming services.

Play with friends

• Open a room and share its 5-digit code, or invite through Steam: up to 8 players.
  
• Everyone plays the same map at the same time, with a live ranking.
  
• Missing the song? Ritsudo sends it to whoever needs it.
  
• Queue up several songs and play them back to back.

Map editor and community maps

Make your own maps by hand, from scratch or starting from the generated map, which stays visible as a guide while you edit. Share them with the song in a single file your friends open by dragging it into the game. You can also download maps made by the community from Steam Workshop.
