Play the Dino Game

What is the Dino Game?

The Dino Game is the small game hidden inside Google Chrome. It shows up when your Internet connection drops, on the grey page that says "No internet". A pixel dinosaur waits patiently on the left side of the screen. Press the space bar and it starts running across an endless desert. From that moment, your only goal is to last as long as possible without hitting anything.

On this page you can play it whenever you want, without cutting your connection and without installing anything. This version keeps the jump physics of the original, its cacti, its pterodactyls and its switch to night mode. It also adds a history of your runs and a ranking of your best scores, so you can follow your progress from one session to the next.

The whole concept fits in one sentence, and that is exactly why it works so well. No menu, no tutorial, no level to unlock. You start, you jump, you crash, you start again. Anyone understands it within seconds, and yet very few players ever get past a few thousand points.

Why people also call it Dino Run

The game never had an official name on screen, so players gave it several. Dino Run is one of the most common, because it describes exactly what you do: keep a little dino running for as long as you can. You will also see T-Rex Runner, which is the name used in the Chromium source code, or simply "the no internet dinosaur game".

All these names point to the same thing. Search for any of them and you will land on the same idea: a character that runs on its own, a single key to jump, and a speed that keeps rising until the fatal mistake. The name Dino Run is sometimes mixed up with an old independent Flash game released in 2008, in which a dinosaur escaped a meteor shower. The two are not related, even if the starting idea feels similar.

The story behind the Chrome Dino

The Chrome Dino was born in 2014 inside the Google Chrome design team. Sebastien Gabriel, Alan Bettes and Edward Jung were working on the browser's error pages at the time. Picking a dinosaur was no accident. The idea was a nod to prehistoric times, a world before the Internet existed. Without a connection, you are sent back to the age of dinosaurs.

Internally, the project was codenamed "Project Bolan", after Marc Bolan, the singer of the rock band T. Rex. At first the dinosaur was just a still illustration on the error page. It became playable in September 2014, first on desktop and then on mobile a few months later, once the team had solved loading issues on slower devices.

Pterodactyls came later, along with the need to duck under some of them. Night mode, which flips the colours at regular intervals, followed. In 2018, for Chrome's tenth birthday, the dinosaur got a party version with a birthday hat and cakes to collect. Around that time Google also said the game was launched roughly 270 million times a month, which makes it one of the most played games in the world even though nobody ever paid for it.

The highest score the counter can display is 99,999 points. Once you reach it, the counter goes back to zero. According to its creators, finishing a run without ever losing would take about 17 million years, roughly the time the real Tyrannosaurus rex lived on Earth. A fun way of saying the game has no real ending.

How to play the T-Rex game

The T-Rex game only uses two keys. The space bar or the up arrow starts the run and makes the dinosaur jump. The down arrow makes it duck. On a phone or tablet, a simple tap on the screen is enough to jump.

How long you hold the key matters a lot. A quick press gives a short hop, handy for clearing a single cactus without staying in the air too long. A longer press gives a higher, longer jump, which you need in front of a group of three cacti. If you keep the key held down, the dinosaur jumps again as soon as it lands.

The down arrow has two jobs. On the ground, it lowers the dinosaur's head so it can pass under a pterodactyl flying at mid height. In the air, it makes it drop faster. Beginners often ignore this second use, yet it becomes essential once the speed climbs and obstacles get closer together.

Obstacles you need to know

• Small cacti, alone or in pairs, can be cleared with a short hop.
• Tall cacti and groups of three need a long jump, triggered a little earlier.
• Low flying pterodactyls are jumped over just like a cactus.
• Pterodactyls at mid height force you to duck.
• High flying pterodactyls pass over you if you stay on the ground.

Pterodactyls only appear after you have been running for a while. The first few hundred points are cacti only, which gives you time to settle in before things get harder.

Speed, score and night mode

The dinosaur speeds up gradually throughout the run. At the start you have plenty of time to see each obstacle coming. After a few minutes, cacti scroll past so quickly that raw reflexes are no longer enough. You have to read the ground ahead and anticipate the rhythm.

Your score goes up with the distance covered. Every 100 points, the counter flashes and a short sound plays. Roughly every 700 points, the scene switches to night mode for a few seconds: the background turns black and everything else turns light. That sudden change throws many players off, especially the first time. The best approach is to focus on the shape of the obstacles rather than on the colours.

On this page, every run is saved in your history. The "Best" tab ranks your top scores, so you can see whether you are really improving or stuck around the same level.

Tips to beat your high score

The first habit to build is looking further ahead. Most mistakes come from staring at the dinosaur itself. If you keep your eyes on the middle or right side of the screen, you spot groups of cacti earlier and pick the right kind of jump without panicking.

Next, learn to control your jumps. A jump that is too long lands you right on the next obstacle. A jump that is too short clips the last cactus in a group. With a bit of practice you will naturally feel how long to hold the key in each situation.

Use the down arrow mid jump as soon as the speed gets high. Landing faster buys you a fraction of a second to prepare the next jump. That is often what separates 1,500 points from 3,000.

When a pterodactyl flies at mid height, duck instead of jumping. Jumping over it is possible, but it is risky and keeps you in the air too long if a cactus follows right behind.

Finally, play in short sessions. After ten or fifteen runs in a row, focus drops and silly mistakes pile up. A break of a few minutes is often all it takes to get back to your best level.

The Google dinosaur on mobile, tablet and desktop

The Google dinosaur is available on every version of Chrome: Windows, macOS, Linux, ChromeOS, Android and iOS. On mobile it starts the same way, by tapping the dinosaur on the error page when you have no signal. Controls are then reduced to a single gesture, the tap, which makes dodging pterodactyls a little trickier.

The version on this page works just as well with a keyboard as with a touch screen. On desktop you get both keys, and therefore the fast drop and the duck. On a phone, turn your device to landscape mode to see incoming obstacles earlier.

In some schools and workplaces, the game is turned off by the network administrator. Chrome includes a setting that lets managed devices block the dinosaur. In that case the error page shows up as usual, but the dinosaur no longer reacts. Playing on a site like this one is then an easy alternative.

Playing the offline dino game or online

The offline dino game is the original version. You turn off Wi-Fi or switch to airplane mode, open a page in Chrome, and the dinosaur appears. It is handy on a train or a plane, but a bit of a hassle when you just want a quick round during a break.

There are two other options. In Chrome you can type chrome://dino in the address bar, and the error page opens right away, even with an active connection. The other option is to play here, in any browser. Firefox, Safari, Edge and Opera all work, since the game runs directly in the page.

The big advantage of the online version is that it keeps track of your results. The original game only remembers your best score for the current session and forgets it as soon as you close the tab. Here, your history is still there when you come back.

What the game really trains

Behind its casual look, this game uses very real skills. It trains your visual reaction time, since every obstacle calls for a quick response. It also works on anticipation, because at high speed you have to decide before the obstacle is even close. And it demands consistency: a single mistake ends the run, whatever your score.

That is why many competitive gamers use it as a quick warm up. A few runs are enough to wake up your reflexes before a more serious session. If you want to measure your reflexes more precisely, a reaction time test in milliseconds is a good complement.

The game also has a calming side. The minimal scenery, the soft sounds and the absence of outside pressure make it an ideal break between two tasks. You can stop at any time without losing progress or missing a daily goal.

Frequently asked questions about the Google Dino Game

Is the Google Dino Game free?

Yes, completely. It is built into Chrome with nothing to buy, and the version on this page is free too, with no sign up and no download.

Can you reach the end of the game?

Not really. The counter stops at 99,999 points and goes back to zero, but the run keeps going. In practice the speed gets so high that most players lose long before that.

Why does my dinosaur die when I did not touch the cactus?

Collision areas follow the drawings quite closely, but not down to the pixel. A jump started too late or a landing that is too slow is often enough to clip the edge of an obstacle. Jump slightly earlier and use the down arrow to land faster.

Does the game work in every browser?

The hidden version only exists in Chrome and Chromium based browsers. The version on this page, on the other hand, works in every recent browser, on desktop and mobile alike.

What is a good score?

Going past 1,000 points shows you have the basics down. Beyond 2,000, you handle speed and pterodactyls well. Passing 5,000 points takes real focus and a very steady read of the ground. What matters most is beating your own record, run after run.
