The randomness of the site means that you just never know and can't control who you are going to interact with next. In our visits, and in news coverage about the site, most of the people using the site appear to be masturbating men - often with the webcam focused on their genitals. The site requires no registration or age verification. You can continue to click Next - and so can the other user - until you find someone you want to chat with. The roulette part comes in because if you don't want to chat with the person you are paired with, you just click Next and another person randomly appears.
All you do is go to the site's homepage, click a button to sync your webcam, and you are instantly connected randomly with other users.
Even if you don't have a web cam, you can still use the site and view the other people using it. Parents need to know that Chatroulette allows anyone with a webcam and Internet connection to instantly video chat with any other visitor anywhere in the world.
