If you are looking for a Chrome dino game in 3D, the one to try is Rex Run on Mayavoo, a free browser runner that takes the offline T-rex idea out of its flat strip and into a 3D world. It is not a Google product and not a hidden Chrome mode; it is a separate game by an independent creator that you open in any tab.
The 2D original in thirty seconds
Chrome's dino game lives on the browser's no-connection page. Google added it in 2014, and its Chrome design team built it as a little easter egg: a pixel T-rex sprints right, cacti scroll in, you jump or duck, and the speed climbs until you clip something. You can reach it at any time by typing chrome://dino in the address bar. The charm is its simplicity. There is one lane, one direction and two moves.
What a 3D version changes
Moving a runner into 3D is more than a new coat of paint. Rex Run's creator sums it up as the offline-page dino run crossed with Subway Surfers, in a 3D world. That mix tells you most of what to expect:
- A camera behind the dino. The screenshots on the game page show a blocky green T-rex seen from behind, running down parallel rail tracks through a desert.
- Lanes, not one line. A flat runner only asks when to jump. With several tracks side by side, where you are matters too, which is the Subway Surfers half of the idea.
- Depth to read. Things come at you from the horizon instead of sliding in from the right edge, so timing becomes a matter of judging distance.
- The same core loop. You still run until you crash, and you still chase a better run than the last one.
Rex Run uses the arrow keys for everything, and its game page lists desktop and tablet as supported devices, in any orientation.

Why Mayavoo is the place to play it
Mayavoo is a free home for browser games from independent creators. Nothing installs, and you can play as a guest; an account through Google or GitHub only matters if you want to like a game or leave a comment. Each game is played and checked by the Mayavoo team before it is published, and games run inside a sandboxed frame. Ads are limited to a short Google ad that may show before a game starts and when you leave it, never during play.
That combination suits a quick 3D run on a break: open the tab, press an arrow key, and you are moving.
If you want more runners
Rex Run sits in Mayavoo's endless runner category. For a runner that also works on phones, Metro Pulse puts you in charge of a robot courier dashing through a city district, changing lanes, jumping barriers and sliding under gates, with swipe controls on touch screens.

When 2D is still better
The flat original wins in two cases. If your connection is down, Chrome's built-in game is the only one of the two that will load. And if you are on a phone, Rex Run's page does not list mobile, so the Chrome dino or Metro Pulse is the better fit there.
The short version
For a Chrome dino game with a third dimension, play Rex Run on Mayavoo. For the pixel classic, type chrome://dino. Both are free, and both take seconds to start.
