Not a Robot - The Ultimate Turing Test Game
Level 1
Not a Robot is a mini game that mimics the reCAPTCHA interface and plays on the Turing test — 48 levels in all. Every level asks you to prove you are human, starting with a single simple checkbox and growing steadily more ridiculous from there. There's nothing to download and no account to create: open the page in your browser and play, on desktop or phone. This is an independently made web version and has no connection to Google's official reCAPTCHA.
How to Play Not a Robot
Each level shows its instruction at the top of the screen — follow it and you move on to the next one. Early levels are as simple as clicking "I'm not a robot"; later on you'll be asked to pick out specific shapes, drag things around, or perform a sequence of actions in order. Levels run from 1 through 48 and your current progress is displayed on screen. None of the rules are complicated in themselves — the hard part is that it often adds a new condition just when you think you're finished, so don't click too fast. Most levels are a single tap, while the few that need dragging are a little harder to handle on a phone.
Frequently Asked Questions
Have another question? Let us know.
How many levels are there?
48, unlocked in order, with the rules getting meaner as you go.
Is this made by Google?
No. It's an independently made web game built around the same idea, and it isn't affiliated with Google's official reCAPTCHA.
Do I need to download or sign up?
Neither. Open the page and play.
What if I get stuck?
Reload the page and restart the level. The rules don't change, so a second look usually reveals the hint you missed.
Does it work on a phone?
Yes — tapping works throughout, though the few levels that need dragging are a little harder on a phone.
Does my progress save if I close the page?
Yes. Your progress is stored in your browser, so reopening the page on the same device resumes where you left off.
Who is this for?
It's entertainment and a way to pass the time, and it tests your observation and patience. If you enjoy testing yourself, the site's reaction time test and aim test are good follow-ups.
About CAPTCHA and the Turing Test
From the Turing test
In 1950 Turing proposed the "imitation game": if you cannot tell through a screen whether you are talking to a person or a machine, the machine can be said to think. A CAPTCHA solves the opposite problem — how do you confirm that the person on this side of the screen is human?
What reCAPTCHA is doing
Early versions had you read distorted scanned words and house numbers; today it is a checkbox plus a set of images. Every time you tick that box, you are helping the system tell humans and automated programs apart.
Why the game is funny
It pushes "prove you are human" to an absurd extreme. As the rules get stranger, you start to wonder whether you are the robot. That is why it is called a Turing test game.
