Order by the date the song was first uploaded or released. You place all 19 cards on one timeline, one at a time. Three wrong guesses ends the run.
Hatsune Miku Songs is a free timeline game you can play right in your browser, with no sign-up and nothing to install. Every card hides a value on the same scale, exact air dates, so the whole run is really one big sorting puzzle. The first card comes up face up. After that you slot each new card into the spot where you think it belongs, and its value only shows once it lands. Guess wrong three times and the run ends with whatever you had down.
Want a longer game? On the deck tree you can tick this deck alongside any other one measured in exact air dates, and they shuffle into a single timeline together.
Here are 19 of the 19 cards you might be dealt. Their values stay hidden until you place them.
