Ribbon run
A rhythm game drawn with a single line. Obstacles arrive on the beat: press the right arrow as each one reaches you. Keep it clean to evolve; slip up and you'll devolve, all the way down to a tumbling carrot.
The numbers
How it works
Four shapes ride the line: blocks (←), loops (↑), pits (↓) and waves (→), with a star above each showing its arrow. Press as the shape reaches you (there's some leeway either side) and your character climbs, loops, strides or rolls over it. Hit them on time to build a combo; every 10 in a row raises your multiplier. A clean streak evolves you from rabbit to rabbit in a dress, then to the queen in her gown and crown, who scores double. Misses and stray presses shake the line and scribble your character; misses also scramble the music and, if they pile up, take you down to frog, snake and finally carrot.
Generated tracks are new synth songs made from a seed: tempo, key, chords and drum patterns all come from it, and the course follows the track's own kicks and snares. The daily challenge is one generated track and course per UK day, the same for everyone; your best for today and your streak of days played stay in this browser.
With your own music file, the course is built from the song's beats before it starts. With tab, device sound or the microphone, the game follows the beat as it listens. On a computer, Tab or device sound can hear any app, such as Spotify: choose Entire screen and tick Share system audio.
