I'm Not a Robot!

Practice different CAPTCHA challenges that websites use to check you're a real person, not a bot

What is a CAPTCHA?

A CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." Websites use them to stop automated bots from creating fake accounts, sending spam, or abusing services. You've probably seen them when signing up for something online or submitting a form!

You'll practice 6 different types:

1

Google reCAPTCHA

The most common CAPTCHA. Google analyzes your mouse movement and behavior. Just click the checkbox!

2

Classic Text CAPTCHA

One of the oldest methods. You must read distorted, wavy letters and type them correctly.

3

Image Recognition (reCAPTCHA v2)

Select specific objects from a grid of images. Robots struggle to identify real-world objects!

4

Math CAPTCHA

Solve a simple math problem. Humans can do this easily, but bots need to be specifically programmed.

5

Word Puzzle CAPTCHA

Complete a common phrase or sentence. Uses everyday knowledge that bots often lack.

6

Image Rotation CAPTCHA

Rotate an image to its correct orientation. Requires understanding of the real world.
