I would say http://satoshiroulette.com/ is a scam site. They wont per say steal your money but they do at the same time. A 0.001 sic bo bet will only pay out 0.0013 its used to be 0.0019 to cover for the fee. It seems every couple of weeks they have slowly added more price to the fee. So for a bet that should pay close to 1:1 they are paying 1:3. Also it is slow as fuck sending back bets.
