In February, Microsoft hid a surfing game (Surf Game) in the program browsing Edge, like easter egg to celebrate the new browser logo.
At the time, it was only available to users of the canary and dev channels of the browser, but as of today, it is available to anyone who wants to try it.
To test it, you should make sure you are using the latter version of Edge. If you don't have it, update the app and then visit the internal address edge: // surf.
The game will start even if you are not connected to the internet.
It's surprisingly neat game for an easter egg, it has cute characters lots of options, powerups and lots of ways to play. In addition to your keyboard, you can use a touch screen or a controller to play.
It's a cute easter egg that will distract you if you use the Microsoft browser. But do not overdo it if you work from home…
