official I/O 2026 page, which, for right now, is all about puzzles before the finish line. The company leads with the tagline: “Make, Build, Unlock,” to start hyping up users. Google says users must “play through all builds to unlock the final bonus. Every play gets you closer to unlocking the Google I/O date.” This is pretty standard business around here for Google, so there’s nothing crazy (yet).

After getting started, users are taken to the five puzzles/games they’ll have to play to reveal the I/O date this year.

The five games are: Hole in One, Nonogram (endless board games), Word Wheel, Supersonic Bot (your mic controls the bot’s altitude), and Stretchy Cat. While the first game is pretty self-explanatory, Google explains that every game leverages Gemini’s AI capabilities in one way or another.

For Word Wheel, Gemini 3 comes in to “automate level design, ensuring every puzzle is balanced and enjoyable.” The AI’s presence in Stretchy Cat is similar; however, it also adds an “endless” mode similar to Nonogram. At the time of writing, the community has just passed the first node in the progress bar. In short, we’re one-fourth of the way to revealing the I/O 2026 conference date.

Prism Shift” game for users to play to reveal the 2025 event date. As its name kind of suggests, users were required to shift around mirrors and nodes to bounce light beams and connect each section. “All nodes” needed to be lit in order to progress.

It was a nice game that really had you focusing on ensuring the lights bounced properly to light everything up. Funny thing is, this game might’ve been too easy for users, as they finished it and revealed the date in a day. I/O 2025 was set for May 20 and 21. Perhaps, we’re looking at a similar timeline this year, too, as Google usually holds its conference in May.
