Strumdle

Strumdle is a daily guessing game inspired by Guitar Hero. In place of a song clip you get the note chart: coloured notes scrolling down a highway, as you would see them in the game. You have to recognise the song from the rhythm and shape of the guitar part.

Press play to watch the chart. The guitar sounds are simulated and the other instruments are synthesized too, so no audio from the original recordings or the games is used; the game tells you to trust the note patterns. You can swap guitar sounds in the audio controls. Some days the chart starts in the middle of a song, and a timer on the highway shows where you are in it.

You type a guess and pick it from the song list. You get six attempts, and after each wrong guess the chart plays two seconds longer. A wrong answer can still help: it is tagged if it is by the same artist or from the same Guitar Hero game as the answer, and the share grid shows those as yellow and blue squares.

The song list draws on the Guitar Hero series, with Guitar Hero: Aerosmith and Guitar Hero: Metallica added in March 2026. Each day has a number, the next one arrives at 01:00 UTC, and past challenges can be played from a grid in the results screen that shows how well you did on each.

Strumdle is made by Makotro, who launched it in March 2026. The guess list holds about 450 songs, and on 27 October 2026 the day's chart opened as a 7 second clip.
