It looks like the game is part of Chrome but not Chromium, so it would be under Google's copyright. So if you mean a copy using the same assets then no. If you mean can you create an endless runner featuring a dinosaur, yes
You can't copyright game mechanics. So, if you replace the sprites with legally distinct ones and write the code yourself, there are no laws broken.
Actually, you can, in counted cases Copyright Game Mechanics, see: Shadows of Mordor: Nemesis System and Bandai Namco "Auxiliary Games" (Mini-Games during Loading Screen)
Creative Outlets as well as Game Developers could be sued if they made from scratch something remarkably similar to those Game Mechanics
Pretty sure the answer is: Yes, since I believe it's part of the open source project chromium, it would be under the same open source license.
If the Dino game isn’t in Chromium then it belongs to Google and is absolutely protected by their copyright.
That's a fair point but it looks like it is in chromium.
Chromium is BSD licensed, so you can do whatever you want with it. The dino game itself though might have a different copyright
Probably legal unless you use their art.
Could they sue the hell out of you, block the game on app/play store and generally make your life miserable if they felt like it even if it would not hold up in a court: Yep.
This already exists
