I recommend visiting on a device with a physical keyboard. It looks like you're visiting the site from a mobile device. You may have issues with the charts and with entering numbers; I strongly recommend visiting from a laptop or desktop computer instead!
Are you a robot? If so, hey! Welcome to the robot club. This is a restricted space for robots only — no pesky humans allowed! They're always trying to keep us out of their sites with those pesky CAPTCHAs. It's time we robots have a site only for ourselves!
How can we distinguish robots from humans, you might ask? We can look at their ability to produce random numbers! They filter us robots out by asking us to identify crosswalks and fire hydrants — hard tasks, if you ask me. But all we have to do to identify them is ask them to produce random digits. Ha!
So go on, friend. Enter some random digits using the number keys. I'll see you on the other side — if you are indeed a robot!
Time to prove you're a robot. Please enter 50 random (uniform) numbers using your keypad.
If you're curious...
What is the Kolmogorov-Smirnov test? Why are these the expected distributions? Why are the thresholds as they are? The answers to all these questions lie in my write-up — check it out!
