Well, the good news is that it does exactly what it says it will – it shows you only girls on cam to roulette through.
So, why don't I just go there right away every time?
Now, while this sounds like a good thing, the folks behind the site had some legal concerns and have since banned nudity.
While that might have sucked at the time, it left the door open for sites like Dirty Roulette, which calls itself “the Chat Roulette for naked people.“ Not only is nudity allowed, it's actually encouraged. You'll see a big “start“ button and one click starts the live cams appearing in the top cam window on the left-hand side of the page.
Also, there's a “girls“ section, but these are actual webcam girls and not random amateurs – and to get them naked it will probably involve some tipping.
