Is there an ending to the Chrome dino game if you just keep running? This page answers the questions people search for most: whether the dino game has an end, what happens at 99999, where the "17 million years" story comes from, the dinosaur game world record and high scores, tips for going further, and whether the old hacks still work. The score and speed numbers below were worked out from Chrome's open-source Chromium code. blockblast.co is an unofficial fan site and is not affiliated with Google.
Does the dino game have an ending?
No. The dinosaur game has no ending screen, no final level and no boss. The only way a run ends is when the T-Rex hits a cactus or a pterodactyl. You get GAME OVER and a restart button, and that's it.
- In the source code, a collision is the only thing that stops the game. There is no time limit and no score that triggers an end.
- There are no levels either, so there's no "level 2". The game just speeds up, and the screen flips to night mode every so often.
- Once the dino reaches top speed, the game stops getting faster. From then on it's the same difficulty forever.
The "17 million years" story
The popular claim that the dino game ends after 17 million years comes from Google itself. In a 2018 interview with the dino's creators on Google's blog, the team said they built the game to max out at approximately 17 million years, the same amount of time the T-Rex was alive on Earth.
Treat that as a joke rather than a hidden ending. Nothing in the source code counts toward 17 million years or shows a final scene, and the speed maxes out after about two minutes. So there's no sad ending or secret story to unlock. What does change over a very long run is how the score is shown.
What happens at 99999? (End score)
The score starts with 5 digits (00000). In the original code, when your score goes past 99999, the counter switches to 6 digits and you keep running. Nothing ends or freezes at 99999.
After that the counter never grows again. Past 999999, only the last 6 digits are shown. A real score of 1,000,120 would appear as 000120. It looks like the score rolled back to zero, but the game keeps counting.
Assuming you never crash, here's how long it takes on a desktop screen at 60 frames per second:
| Milestone | Score | Time |
|---|---|---|
| Pterodactyls can start appearing | about 450 | about 42 seconds |
| Top speed reached | about 1,660 | about 1 minute 57 seconds |
| 99999 (counter becomes 6 digits) | 99,999 | about 86 minutes |
| 999999 (only last 6 digits shown) | 999,999 | about 14 hours |
At top speed the score climbs by about 19.5 points per second. On a narrow game screen, such as a phone held upright, the game runs slower, so each milestone takes longer.
Dinosaur game world record and highest score
There is no official dino game leaderboard. Your high score (HI) is stored only in your own browser. Chrome doesn't send it to Google, and there's no built-in way to compare scores with other players.
As for a world record, we couldn't find any Guinness World Records–certified record for the Chrome dinosaur game. You'll find plenty of "world record" videos and high score screenshots online, but none of them are verified by an official body, so there's no way to know which are real.
- Screenshots and videos can be edited, so a single image doesn't prove a run was actually played.
- The counter tops out visually at 999999, so anything beyond that can't be confirmed from the screen.
- Difficulty stops rising after about two minutes, so the highest scores come down to focus and not making a single mistake, not to surviving a harder stage.
If you're chasing your own best score, the tips below are what actually matter.
Tips to get a higher score in the dinosaur game
Handle each pterodactyl height differently
In the original code, pterodactyls fly at three heights on desktop. On touch devices like phones and tablets there are only two: low and high.
| Pterodactyl height | If you keep running | What to do |
|---|---|---|
| Low (near the ground) | You crash | Jump. Ducking still hits it |
| Middle (head height) | It hits your head | Duck (↓) is the safest option. Jumping over works too, but the timing is tight |
| High (above your head) | It passes over you | Do nothing and keep running. Jumping can make you hit it |
Pterodactyls fly slightly faster or slower than the ground scrolls, so jumping with the same timing you use for cacti often goes wrong. Judge by the height of the body, not the flapping wings.
Control your jump length
- A quick tap gives a short, low jump. Holding the key gives a higher, longer one. Tap for a single small cactus and hold for a wide group.
- Press ↓ in mid-air to drop down fast. This helps when another obstacle comes right after the one you just cleared.
- At higher speeds the same press sends the dino a little higher, so expect your timing to shift as the game speeds up.
Don't panic at night mode
Every 700 points the colors invert for about 12 seconds. Obstacles and hitboxes don't change, so keep your rhythm. The score flashing every 100 points doesn't affect anything either.
Practice with a keyboard
A keyboard beats a touchscreen for long runs: you get Space, ↑ and ↓, and you'll practice against all three pterodactyl heights. You don't need to disconnect from the internet to train. Just practice in the Chrome dino game on our page.
Dino game hack prompt and inspect cheats: do they still work?
For years, a popular trick was to open Chrome's DevTools (Inspect), go to the console and paste code starting with Runner.instance_ to make the dino invincible or change its speed. Those copy-paste snippets no longer work in current versions of Chrome.
- We pasted the old snippets into the console on chrome://dino in Chrome 152 (September 2026). They stopped with an error and did nothing.
- The reason is that Chrome's dino code has been restructured, and the
Runner.instance_those snippets rely on no longer exists. - We don't publish cheat steps or code on this page.
Our version doesn't include an invincibility mode or console cheats either. And in general, avoid pasting code you don't understand into the console. Chrome warns about this for a reason: it can expose your accounts or personal data.
Chrome Dino birthday edition
In September 2018, the dino got a birthday edition for Chrome's 10th anniversary. According to Google's official blog, it added a birthday cake, balloons and a party hat. The dinosaur game itself launched in 2014, so the 10th birthday was Chrome's, not the dino's.
The 2018 interview linked above also says the game was made by Edward Jung, Sebastien Gabriel and Alan Bettes of the Chrome design team under the codename "Project Bolan".
The game on this site is a port of the standard version, not the birthday edition. When you're ready, play the dinosaur game unblocked with the original graphics and sounds.
Dino Game Ending FAQ
Can you beat the dinosaur game?
No. There is no ending screen in the source code, and the game only ends when you crash. The speed reaches its maximum after about two minutes, and after that the difficulty stays the same for as long as you can keep going.
What is the max score in the dino game?
There is no fixed maximum. The counter shows up to 6 digits, so after 999999 you only see the last 6 digits of your score. The game keeps counting underneath.
How long would it take to reach 99999?
About 86 minutes of perfect play on a desktop-sized game screen, and about 14 hours to reach 999999. On a narrow screen, such as a phone held upright, the game runs slower, so it takes longer.
What happens after 999999?
The counter only shows the last 6 digits, so it looks like it rolls back toward zero. A real score of 1,000,120 appears as 000120. Your run doesn't end and the actual score isn't reset.
Do Runner.instance_ hacks still work?
No. The old snippets passed around online don't work in current Chrome: when we pasted them into the console in Chrome 152 (September 2026), they failed with an error and did nothing. Our version has no invincibility mode either.
Is there an official dino game leaderboard?
No. Your high score is saved only in your own browser, and Chrome has no online ranking. We also couldn't find any Guinness World Records-certified record for the game, so online world record claims can't be verified.
