chrome dinosaur game won't start anymore

on a phone, chrome://dino works too, you just tap the dino instead of pressing space. if you get the no internet page with no dino at all, that's usually the admin block mentioned above.

you don't need to go offline for it, just type chrome://dino in the address bar and press space. if that page shows nothing on a school or work laptop, the admin has probably switched the game off - that's a policy they can set, nothing broken on your end.
