This year’s Google I/O will take place from May 17th through the 19th at the Shoreline Amphitheatre in Mountain View, California, Google revealed today through an elaborate puzzle. The company tweeted a cryptic link, as first spotted by 9to5 Google, on its developer Twitter account. That tweet linked back to a save the date page, which then redirected users to a GitHub page. The GitHub repository contained five puzzles that, when solved, confirmed the details.

Around the world, from here to there, to the most clever minds, the secret will share. #googledevs #savethedate https://t.co/0zwCbSLzVy pic.twitter.com/0O2vNDWZx2 — Google Developers (@googledevs) January 24, 2017

According to Android Police, the puzzle, which involved coordinates and a chess board, was ultimately solved on a Discord channel dedicated to solving it. Google’s official I/O page still isn’t updated, and we don’t have details on registration. Hopefully Google will reveal those soon — presumably it will use a lottery system to dole out passes again this year. It’s the second year that Google has held its developer conference outdoors.

At last year’s I/O, Google made machine learning a central theme. The company also announced Home, its now-canceled Project Ara modular phone, Daydream VR, Allo, and Duo.
