Hidden Games in Your Browser: 5 Easter Eggs You Can Play Right Now

Somewhere between spreadsheets and endless tabs, browser developers have been quietly hiding video games inside their products for over a decade. No downloads, no accounts, no app stores – just secret key combinations and internal URLs that most users never stumble upon. Here are five playable easter eggs hiding in the software you already use every day, and how to launch each one.

1. Chrome: the legendary T-Rex runner

The most famous hidden game in software history lives behind Chrome’s “No Internet” error. In 2014, Google’s UX team decided that a dead connection shouldn’t mean dead time and buried an endless runner inside the error page: a pixelated T-Rex sprinting through a desert, jumping cacti and ducking pterodactyls. The project’s internal codename was Project Bolan  – a tribute to Marc Bolan, frontman of the rock band T. Rex.

Three ways to play it:

• The classic way: lose your connection, open Chrome, press Space.
• The secret URL: type chrome://dino into the address bar – the game launches instantly, no outage required.
• Any browser, any device: play Chrome Dino online – the same game plus color, night and themed variants that the built-in version doesn’t have.

Don’t let the one-button simplicity fool you. The game hides a surprising amount of craft: the world flips into night mode at 700 points, the moon cycles through seven phases across consecutive nights, and Google’s engineers joked that completing the game would take about 17 million years – roughly how long the real T-Rex existed. It’s played around 270 million times every month, which makes an error page one of the most popular games on the planet.

2. Edge: catch a wave with the surfing game

Microsoft answered the dinosaur in 2020 with a full-blown surfing game inspired by the classic SkiFree from Windows Entertainment Pack. Type edge://surf into Edge’s address bar and you get a character surfing an endless ocean, dodging buoys, islands and – in a direct SkiFree homage – a tentacled kraken that chases you down just like the infamous yeti once did.

Compared to the minimalist dino, Edge’s game is almost extravagant: three modes (endless, time trial, slalom), power-ups, character selection and even gamepad support. It also works offline, appearing automatically when Edge can’t reach the network.

3. Firefox: the unicorn pong nobody finds by accident

Firefox hides the most obscure entry on this list. Open the menu, choose More tools → Customize toolbar, then drag every single item out of the toolbar and overflow menu. When nothing is left, an empty-state graphic appears – click it, and a tiny game of Pong starts, with a unicorn as the ball. Mozilla’s developers built it as a reward for the roughly zero users who would ever strip their toolbar completely bare, which is exactly what makes it delightful.

Firefox veterans will also remember about:mozilla  – not a game, but the browser’s oldest easter egg: a passage from the fictional “Book of Mozilla” that has been updated with each major era of the browser since the Netscape days.

4. Google Search: a whole arcade in the results page

Google’s search results double as a free arcade if you know what to type. Search for “pacman” and the playable 2010 anniversary doodle appears right at the top. “Tic tac toe”, “solitaire” and “minesweeper” all launch playable versions directly in the results. Searching “snake game” opens Google’s own take on the Nokia classic.

Some legends have retired – the beloved “zerg rush” easter egg, where little O letters devoured your search results, was quietly removed – but the doodle archive at google.com/doodles still preserves playable classics, including the full Pac-Man board shaped like the Google logo.

5. Android: the hidden mini-game in your version screen

Not strictly a browser, but too good to skip: every Android phone ships with a hidden game. Open Settings → About phone and tap “Android version” several times quickly, then long-press the logo that appears. Depending on your OS version you’ll get a different surprise – the most famous being the Flappy Bird clone with a flying Android robot that Google shipped after the original Flappy Bird was pulled from app stores in 2014. Newer versions hide different toys, from a cat-collecting game to a virtual watch face.

Why do developers keep hiding games?

There’s a practical answer and a human one. Practically, the Chrome dino proved that a well-placed easter egg converts a moment of user frustration – no internet, a crashed page, a boring settings screen – into a moment of goodwill. That’s cheap, powerful UX.

The human answer is older than browsers: programmers have been signing their work with hidden surprises since the first known video game easter egg in Adventure on the Atari 2600 in 1980. A hidden game is a small message from the people who built your software – a reminder that behind every product there’s someone who wanted to make you smile when you least expected it.

So next time your Wi-Fi dies, don’t reach for your phone. Press Space instead.
