Google I/O 2023

To announce the date of the 2023 Google I/O developer conference, this puzzle was created for attendees (and other interested parties) to solve. When enough users had solved the two included puzzles, the date was revealed to everyone. One type of puzzle was a color puzzle where players needed to toggle the colors in the correct order, and the other type of puzzle utilized binary functions in a grid where players shifted columns and rows like a Rubik's Cube. There was a total of seven puzzles, and players who successfully completed them were given a special badge for social media. As more players completed more of the puzzles, the date of Google I/O (May 10) would fill in. The date was revealed within six hours of the game launch.
