- 100mBTC guaranteed, even if you don't finish in top7. A few requirements apply, but they are quite easy to fulfill
Wagering 3 BTC on (possibly rigged) SoftSwiss casino games without losing it all isn't easy, so I wouldn't call it "guaranteed" because otherwise people would join, place a lot of bets on low odds stuff, and come out in the green.
Hello DarkStar, I won't extend many comments on the "possibly rigged" part, but as usually I don't think casinos have any reason to do so.
Related to the competition itself, many users choose to use the "strategy" you described. We always encourage users to compete to win, by awarding Top7 prizes with no rollover (The prizes are paid to any address you like, so you can do with it anything you want). But a prize is a prize, so some users, prefer to play it safe and bet at low odds and just collect those 100mBTC. We never had any complains for that rollover, in fact the feedback we usually get is quite good, and users manage to complete the rollover very fast (some say they did it in less than 30min of play), and come out very close, sometimes even above, the initial prize.
