How they compare
SlutRoulette runs on Streamate's model network, so the performers are largely the same. The difference is how you find them.
Streamate is the long-running original, built around private shows: browse and search the roster, chat in free rooms, then go private with a model, from about $1 to $5 or more a minute at the time of writing.
SlutRoulette turns it into a game: you spin from one live model to the next at random, watch public shows free, and pay per minute in "gold" for private, exclusive and cam-to-cam shows. Signing up puts a small one-time authorisation on your card, refunded within 7 to 14 days.
