What Are Google Easter Eggs?
A Google Easter egg is a hidden, interactive feature or visual joke embedded in a Google product — typically Google Search — that is activated by searching a specific phrase or performing a specific action. They are not documented in any official Google help article, are never advertised, and exist purely as gifts from Google's engineering team to the internet at large.
The term "Easter egg" in a software context predates Google by decades. The first documented software Easter egg is generally credited to Atari programmer Warren Robinett, who secretly added his name to the 1980 Atari 2600 game Adventure — bypassing an Atari corporate policy that prohibited crediting individual developers. Players had to perform an elaborate series of hidden actions to access a secret room displaying his name.
Google's Easter eggs operate on a different level — instead of being hidden from the developer's employer, they are hidden from the user. Google's engineering culture has historically celebrated creative side projects and humor. Many Easter eggs were reportedly built during "20% time," the legendary Google policy that allowed engineers to spend one day per week on personal projects unrelated to their core job.
Some Easter eggs are purely visual, like "Do a Barrel Roll" (the page spins) or "Askew" (the page tilts). Others are fully interactive games, like the Pac-Man Doodle or the Snake game. Some are mathematical jokes, some are tributes to gaming history, and some are references to internet culture that only a certain generation will fully appreciate.
1. Do A Barrel Roll
ActiveSearch: "do a barrel roll" or "z or r twice"
The most famous Google Easter egg. The entire search results page performs a smooth 360-degree CSS rotation. Inspired by the Nintendo 64 game Star Fox 64, where the character Peppy Hare shouts 'Do a barrel roll!' and the player performs the move by double-tapping Z or R on the controller.
The animation uses a CSS transform applied to the document body, rendered entirely by the GPU. It lasts approximately one second. Google has maintained this Easter egg through numerous search interface redesigns over more than a decade.
2. Google Gravity
Third-party mirrorsSearch: "Google Gravity" — look for Mr. doob's version
Originally built as a Chrome Experiment by Ricardo Cabello (known online as Mr. doob), Google Gravity caused all elements on the Google homepage — the logo, search bar, and buttons — to fall to the bottom of the screen under simulated physics. Users could then pick up and throw the elements with their mouse.
The physics simulation used the Box2D engine running in JavaScript — a remarkable achievement for 2009 when browser JavaScript performance was a fraction of what it is today. It was later featured in Google Labs. While the original URL no longer works, mirrors are widely available.
3. Zerg Rush
Intermittently activeSearch: "Zerg Rush"
A tribute to the real-time strategy game StarCraft. Searching 'Zerg Rush' caused a swarm of small, animated 'O' characters (resembling the O's in Google's logo) to pour from the top of the screen and attack the search results, destroying them from top to bottom. Each 'O' required three clicks to defeat.
The name comes from the 'Zerg rush' strategy in StarCraft, where Zerg players flood the map with cheap, fast units early in the game to overwhelm the opponent before they can establish defenses. If you failed to click-kill the O's fast enough, they would consume all your results and then form a 'GG' (Good Game) formation on screen.
4. Atari Breakout
No longer activePreviously: Search "Atari Breakout" in Google Images
To celebrate the 37th anniversary of the classic Atari arcade game Breakout, Google transformed Google Image Search into a fully playable version of the game. The image thumbnails in the search results became the blocks, and a paddle controlled by the mouse sat at the bottom of the screen.
It was one of the most ambitious Google Easter eggs in terms of gameplay depth. The ball speed increased as you cleared rows, recreating the exact difficulty curve of the original Atari game. Google removed the Easter egg during a major redesign of Image Search, but standalone recreations are easily found online.
5. Askew (Tilt)
ActiveSearch: "Askew" or "Tilt"
A subtle but highly effective visual gag. Searching 'Askew' or 'Tilt' applies a slight CSS rotation to the search results page body — just enough to make the page look crooked, as if your monitor is slightly off-level. It produces a disorienting double-take moment before you realize the page is intentionally tilted.
The effect is achieved with a CSS transform applied at a small angle (approximately 2-5 degrees). Unlike 'do a barrel roll,' which performs a full 360-degree rotation and returns to normal, 'Askew' maintains the tilt for as long as the search results page is open. It is one of Google's most quietly clever Easter eggs.
6. Blink HTML
ActiveSearch: "Blink HTML"
A nostalgic nod to the much-maligned <blink> HTML tag from the early web era. Searching 'Blink HTML' causes all instances of the words 'blink' and 'html' in the search results to flash on and off in a blinking animation — recreating the exact behavior of the deprecated tag.
The <blink> tag was a non-standard HTML element originally implemented by Netscape Navigator in the early 1990s. It caused text to flash repeatedly, quickly becoming notorious as one of the most overused and irritating features of early website design. It was removed from modern web standards, and Google's Easter egg is a knowing, ironic tribute to its memory.
7. Play Pac-Man
ActiveSearch: "Pac-Man" or "Play Pacman"
Originally launched as an interactive Google Doodle in 2010 to celebrate the 30th anniversary of Pac-Man's release, the game was so popular that Google gave it a permanent home. Searching 'Pac-Man' or 'Play Pacman' brings up a fully playable version of the original arcade game embedded directly in the search results.
The 2010 Doodle was remarkable for its fidelity to the original. Google reportedly spent several months recreating the precise physics, ghost AI behavior, and level progression of the original 1980 Namco arcade game. The ghost characters (Blinky, Pinky, Inky, and Clyde) each retained their original behavioral patterns.
8. Play Snake
ActiveSearch: "Play Snake" or "Snake Game"
A fully playable version of the classic Snake game, embedded directly in Google Search results. The snake grows longer as it eats, and the game ends when the snake runs into itself or the wall. Multiple visual themes are available.
Snake's cultural roots stretch back to the 1976 arcade game Blockade, though it became internationally famous as a pre-installed game on Nokia mobile phones in the late 1990s. Billions of people played Snake on their Nokia 3310 or 3210. Google's version is a polished tribute that works on both desktop and mobile search.
9. Tic-Tac-Toe
ActiveSearch: "Tic Tac Toe"
A playable tic-tac-toe game that appears directly in search results. You can play against the computer at various difficulty levels, from easy (which deliberately makes mistakes) to impossible (which uses optimal game theory and can only be beaten if the computer starts first and makes a mistake — which it won't).
The 'impossible' difficulty uses the minimax algorithm, a classic artificial intelligence technique for computing the optimal move in a perfect-information game. Tic-tac-toe is what game theorists call a 'solved game' — an optimal play by both sides always results in a draw. The computer never deviates from optimal play at maximum difficulty.
10. Elgoog — Do A Barrel Roll Backwards
ActiveVisit: elgoog.im (Google spelled backwards)
Elgoog is an unofficial mirror site that displays a fully mirrored version of the Google search interface — every word, the logo, and the layout are all reversed. Originally created as a novelty around 2001, elgoog gained a following when students discovered that school network filters often blocked google.com but not elgoog.im. Remarkably, 'do a barrel roll' still works on elgoog — the entire mirrored page spins just like the real thing.
Searching 'elgoog do a barrel roll' is one of the more obscure barrel roll variants in the keyword landscape. The site itself has outlasted dozens of similar novelty domains and remains one of the oldest active Google-adjacent Easter egg destinations on the internet. Type 'llor lerrab a od' (do a barrel roll backwards) in the elgoog search bar for an extra layer of absurdity.
11. Do A Barrel Roll — Minecraft Mod
Community modInstall: 'Do A Barrel Roll' mod (Modrinth / CurseForge) for Minecraft Java Edition
The 'Do A Barrel Roll' Minecraft mod adds a literal barrel roll mechanic to Minecraft's Elytra flying system. While airborne with an Elytra equipped, players can execute a mid-air barrel roll by pressing a configurable key. The mod was directly inspired by the Google Easter egg and Star Fox 64, and has accumulated hundreds of thousands of downloads on Modrinth and CurseForge.
The mod is a full-circle tribute: Nintendo creates Star Fox 64 (1997), Peppy Hare shouts 'Do a barrel roll!', Google turns the phrase into a CSS animation Easter egg (2011), and the Minecraft modding community adds physics-accurate barrel roll flight to one of the world's most popular games. The chain from a 1997 N64 voice line to a Minecraft Elytra mechanic is one of internet culture's more unexpected lineages.
12. Driving Mad — Barrel Roll Physics Game
ActivePlay: driving-mad.io (search 'Driving Mad io barrel roll')
Driving Mad is a browser-based physics driving game in which vehicles must navigate extreme obstacle courses, including ramps that launch the car into mid-air barrel rolls. The game became associated with the 'do a barrel roll' keyword cluster through players sharing clips of spectacular crash-and-spin moments. It is not a Google Easter egg, but it ranks for many barrel-roll-related searches.
The game's popularity illustrates a broader pattern: 'do a barrel roll' as a search phrase has expanded far beyond its Google Easter egg origins into a general descriptor for any spinning vehicle, aircraft, or object in a game. Driving Mad players specifically seek out ramps and obstacles designed to produce the most dramatic barrel roll physics, sharing the results as short video clips.
The Golden Age of Google Easter Eggs
The period from 2010 to 2015 is widely regarded as the golden age of Google Easter eggs. During this time, Google was rapidly expanding its engineering workforce, the "20% time" policy was in full effect, and the company had a genuine appetite for playfulness that sometimes seemed at odds with its rapidly growing corporate ambitions.
The Easter eggs from this era were technically impressive for their time. Google Gravity (2009) used JavaScript physics simulation running at acceptable frame rates in a browser — something that would have been impossible a few years earlier. The Pac-Man Doodle (2010) was a faithful recreation of a complex arcade game built entirely in HTML5 and JavaScript, without Flash. The barrel roll (2011) demonstrated CSS3 transform animations with hardware acceleration.
Each Easter egg was, on one level, a joke — but on another level, it was a technical showcase. Google was demonstrating what the modern web could do, and they were doing it in a way that millions of non-technical users could experience and share. The Easter eggs were viral marketing for web standards.
In more recent years, as Google has grown into a more regulated and cautious corporation, new Easter eggs have appeared less frequently. Many of the most elaborate old Easter eggs have been quietly retired. But the classics — barrel roll, Askew, Pac-Man, Snake, Tic-Tac-Toe — remain active as of 2025, maintained through Google Search redesigns as a nod to history and user love.
Easter Eggs Beyond Google Search
Google's Easter egg tradition extends well beyond Google Search. YouTube has hidden several over the years — at various times, searching "use the force luke" caused the page elements to float, and "do the harlem shake" triggered the video page to dance. Android operating systems have featured elaborate animated Easter eggs in the "About Phone" menu since version 2.3, often providing a small playable game or visual experience when the version number is tapped repeatedly.
Google's Chrome browser has a built-in dinosaur game that activates when you lose your internet connection and try to load a page. The game — a side-scrolling runner where a pixelated dinosaur jumps over cacti — has become beloved in its own right, with secret tricks: holding the spacebar on the game-over screen at just the right moment produces special effects, and at very high scores, the day/night cycle switches. You can also access the dinosaur game directly by navigating to chrome://dino even when you have a working internet connection.
How to Find New Google Easter Eggs
Google no longer announces new Easter eggs, but a dedicated community of users actively searches for them. The most reliable methods for finding undocumented Google Easter eggs include:
- Searching Google's trending terms related to games and pop culture — Google has a pattern of adding Easter eggs tied to anniversaries, game releases, and cultural moments
- Watching Reddit communities like r/google and r/InternetIsBeautiful — Easter egg discoveries spread quickly on Reddit
- Exploring Google Doodles — many anniversary Doodles are interactive and extend the Easter egg tradition
- Searching mathematical or science terms — Google has Easter eggs for searches like "Euler's number," "Conway's Game of Life," and various mathematical constants
