The wagering requirement on fortunejack was implemented last year. When the rule was added for the first time it was set to x5 then it was reduced to x2 because a lot of users complained. After some digging here are some of the old posts about the said wagering requirement from their official thread. Reaching the x2 rollover should be easy on FJ since they have dice.
About 5x wagering rule, it has been there for months already, it is not understandable why it is a problem now, all of a sudden when it was not from the beginning. 5x wagering requirement is not roguish or too high and will stay as our rule to protect FortuneJack of money laundering.
Thank you for your input everyone, wagering requirement will be lowered down to x2 soon and as soon as the change will be done all FortuneJack users will receive a notification through their FJ account messages.
