Hidden Browser Games: Chrome Dino, Edge Surf and Firefox's Unicorn
Three browsers ship a hidden game. Chrome has the dinosaur runner (chrome://dino, or any offline page). Microsoft Edge has Surf, a Windows-95-style surfing game at edge://surf. Firefox has a unicorn: open the Customize Toolbar screen, drag every item out of the toolbar, and click the unicorn that appears to play Pong. Safari has none.
Updated

Chrome: the dinosaur
The original and the most-played. Since 2014, Chrome's offline error page has been a runner: press space and the pixel T-Rex jumps cacti and ducks pterodactyls until you crash. Open it deliberately at chrome://dino. Because Chrome's engine is shared, the same URL works with the browser's name swapped in — edge://dino, brave://dino, opera://dino. The dinosaur game page here runs it in every browser, and the history page tells the story.
Edge: Surf
Microsoft Edge answered the dinosaur in 2020 with Surf, at edge://surf and on its offline page. It is a loving remake of SkiFree (the 1991 Windows game) on water: steer a surfer down an endless course, dodge rocks, buoys and other surfers, collect speed boosts and coins, and try to outrun the kraken that eventually comes for you. Three modes — Let's Surf (endless), Time Trial, and Zig Zag — and a choice of characters. Play Edge Surf here if you are not on Edge.

Firefox: the unicorn
Firefox's game is better hidden. Open the menu, choose More tools → Customize toolbar, and drag every single item out of the toolbar and into the palette. When the toolbar is empty, a small unicorn appears in the corner of the customize screen. Click it, and it starts a game of Pong with the unicorn as the ball — the paddles are controlled with the mouse. There is no URL for it and no score; it exists to reward the curious.
Safari
Nothing. Apple has never shipped a game in Safari, and its offline page is just an error. Every game on this site runs in Safari, including the dinosaur — so on a Mac or iPhone this site is effectively Safari's hidden game.
Not the browser, but close: Google Search
People often mean Google's search games when they say "hidden browser games": Snake, Pac-Man, Minesweeper, Tic-Tac-Toe, Solitaire, and the tricks like "do a barrel roll". Those live on google.com, not in the browser, and they are all on the Google games hub.
Frequently asked questions
How do you play Edge Surf?
In Microsoft Edge, type edge://surf into the address bar. Arrow keys or WASD steer; space or F brakes and the F key also fires a speed boost you collect on the water. Surf also appears on Edge's offline page, exactly like Chrome's dinosaur.
How do you find the Firefox unicorn game?
Open the Firefox menu → More tools → Customize toolbar. Drag every icon out of the toolbar into the palette until the toolbar is empty; a unicorn appears in the bottom corner. Click it to play a Pong game with the unicorn as the ball.
Does Safari have a hidden game?
No. Safari has never shipped an easter-egg game. The dinosaur game on this site works in Safari, on Mac, iPhone and iPad.
Is Edge Surf the same as the dinosaur game?
Same idea, different game. Both are offline-page easter eggs, but Surf is a top-down surfing game inspired by SkiFree, with obstacles, a kraken, and three modes. Chrome's is a side-scrolling runner.
