Google’s annual I/O puzzle is back.

As usual, Google has chosen to reveal the date of its I/O developer conference through a collaborative puzzle. For I/O 24 it’s a Pipe Dream-style game, guiding a marble from point A to point B.

Completing your levels helps the overall progress (and probably trains generative AI models somehow), which you can monitor on the main event page. Or, just wait for others to finish it while you dig through the I/O 23 announcements to see what has or has not shipped yet.
