I stopped playing at FortuneJack on February 19, 2018. I found my thread from that time... Not a huge problem, but their support was horrible, and after that "incident" with slots I stopped playing and I never visited FJ again. I found much better casinos around, and I still think that some other casinos are better than FJ.
As Notblox1 I will not say that FJ is a scam, they had a good start, but something in their "relationship" with us players went sideways. I don't have any plans to try them again...
Depends on how you define "a scam". If it's an organisation that always scams, of course not, FortuneJack is not a scam. If a scammer is someone who sometimes scams, sometimes not, then yes they're a scam. But for most people I have to agree they're not a scam yet.
