It was supposed to be a Friday like any other back in May 2010. People logged into their computers, opened a browser, and then—total chaos. Instead of the standard primary-colored logo, Google had replaced its homepage with a fully playable, 256-level recreation of a 1980s arcade classic. This wasn't just a static image. It was the Google Pac Man easter egg, a playable tribute to the 30th anniversary of the yellow puck-man’s debut.
Honestly, the world stopped.
RescueTime, a time-tracking software company, famously estimated that the doodle cost the global economy roughly $120 million in lost productivity. That’s about 4.8 million hours of collective human life spent munching power pellets instead of filling out spreadsheets. It was arguably the first time a search engine "easter egg" became a legitimate cultural event. While most people think it was a one-day gimmick, the truth is that the code is still live, still playable, and carries some technical quirks that even die-hard retro gamers tend to miss.
The Secret "Two Player" Mode Nobody Found at First
Most people just hit the "Insert Coin" button—which replaced the "I'm Feeling Lucky" button—and started playing as Pac-Man. But there’s a nuance here that feels very "Old Google." If you clicked "Insert Coin" twice, Ms. Pac-Man joined the fray on the same keyboard.
Player one used the arrow keys. Player two used the WASD keys.
It was a chaotic, cramped experience if you were sharing a laptop, but it was a brilliant nod to the cooperative (and competitive) nature of 80s cabinets. Ryan Germick, the Google Doodle team lead at the time, worked closely with Marcin Wichary to ensure the logic was sound. They didn't just slap a skin on a generic maze game; they meticulously recreated the original logic of the ghosts.
Inky, Blinky, Pinky, and Claude?
The AI logic in the Google Pac Man easter egg is surprisingly faithful to the 1980 ROM. If you’ve ever felt like the ghosts are "predicting" where you’re going, it’s because they basically are. They aren't just chasing you.
Blinky (the red one) is the only ghost that truly pursues you directly. Pinky (pink) tries to get about four spaces ahead of where you are facing to cut you off. Inky (blue) is the "wildcard" because his movement is based on a vector calculation between Blinky’s position and yours. If Blinky is far away, Inky becomes timid. If Blinky is close, Inky becomes aggressive.
Then there’s Clyde (the orange one). Most people think he’s just stupid. Actually, his code tells him to chase you until he gets within eight tiles of your position, at which point he "panics" and retreats to the bottom-left corner. Understanding this isn't just for trivia nights; it’s how you actually beat the Google version without losing your mind. The maze in the Google version is shaped like the word "GOOGLE," which changes the pathing slightly compared to the traditional rectangular arcade maze, making the ghost corners even tighter.
Why it stayed online forever
Usually, Doodles disappear. They go into the archive and you have to dig for them. But the Google Pac Man easter egg was different. The public outcry when it was scheduled to be taken down was so loud that Google gave it a permanent home.
You can still find it by searching "Pac-Man" directly in the search bar. It triggers what’s known as a "knowledge graph" interaction. It’s no longer just an easter egg; it’s a permanent feature of the search engine's infrastructure.
Technically speaking, the 2010 version was a landmark for web development. It was built using HTML, CSS, and JavaScript at a time when most high-end browser games still relied on Flash. Since Flash was already beginning its slow death march (thanks to Steve Jobs and the iPhone), this doodle served as a "proof of concept." It showed that the "Open Web" could handle complex sprite animations and sound triggers without third-party plugins.
The Level 256 Glitch
If you are a true masochist and manage to play through 255 levels, the Google version supposedly honors the original "kill screen." In the original arcade hardware, the level counter was stored as an 8-bit integer. When it hit 256, the counter overflowed, causing the right half of the screen to turn into a garbled mess of letters and symbols, making the level impossible to complete.
While the Google version is built on modern code that doesn't have those 8-bit limitations, the developers intentionally added a "kill screen" aesthetic for those who have the patience to get that far. It's a love letter to technical failure.
How to play the Google Pac Man easter egg like a pro
If you're looking to actually kill time or set a high score on the Google version, you need to change how you look at the maze.
- The "T" and "L" Gaps: Because the maze spells GOOGLE, the "G" and "E" create dead ends that don't exist in the original game. Avoid these unless you have a power pellet. You will get trapped.
- The Tunnel: Like the arcade version, ghosts slow down significantly when they pass through the side tunnels. You do not. Use the tunnels to create distance.
- The "Wiggle": Ghosts in this version have a slight delay in their turn logic. If you rapidly tap a direction you aren't actually going, you can sometimes "trick" the pathing logic into thinking you are heading for a different intersection, though this is harder to pull off on a keyboard than a joystick.
Beyond the search bar: Other Pac-Man secrets
Google didn't stop with the 2010 doodle. They have a weird obsession with this game.
In 2015, for April Fools' Day, they turned the actual streets of Google Maps into a Pac-Man level. You could literally play through your own neighborhood, dodging ghosts on Broadway or Main Street. They brought a version of this back for Ms. Pac-Man later on.
It’s worth noting that these "easter eggs" aren't just for fun. They serve as massive stress tests for Google’s servers and browser compatibility. When millions of people are simultaneously running a JavaScript game on the same URL, it provides a goldmine of telemetry data.
Actionable Next Steps for the Retro-Curious
If you want to dive deeper than just a five-minute break, there are a few things you can do right now.

First, go to the Google search bar and type "Pac-Man." Don't just play; try to trigger the two-player mode by clicking "Insert Coin" twice. If you're on mobile, this won't work—you need a physical keyboard.
Second, check out the Google Doodle Archive. They have a dedicated page for the 30th Anniversary where you can read the original blog post from 2010. It’s a fascinating look at the "Web 2.0" era of design.
Lastly, if you find the Google version too easy or too glitchy, look into the "Pac-Man Museum" or the "Arcade Archives" versions on modern consoles. They use the original ROMs rather than a JavaScript recreation. The "Google version" is essentially a very high-quality "clone," but the timing on ghost patterns is slightly different due to the frame rate of your browser versus the 60Hz refresh rate of an original arcade monitor.
The Google Pac Man easter egg remains the gold standard for what a brand can do when they stop taking themselves seriously for a second. It wasn't an ad. It wasn't a "deep dive" into a corporate strategy. It was just a game. And sometimes, that's exactly what the internet needs.
