Captcha is code is way to determine is user real person or bot. Usually there is solving puzzle, write some letters, do simple math task.
Coder Guillermo Rauch made a captcha from Doom game. If you want past captch you must kill three monsters before they kill you.

Wow, that's a cool method. I hate the CAPTCHAs that requires me to retype things. So that is an improvement. I don't mind those CAPTCHAs that requires me to click things, but this one is cool. I will prefer this over retyping and solving a math problem.

I like it to but I need much more attempt to finish it than usuall captch. I guess I lost touch in video games. Did you try it on smartphone?
