FortuneJack always come up with some incredible promotions and closing Invincible Jackmate will not matter much. What's unique with FJ is that they come up with the campaigns for their new promotions. Recently they launched a promotion for their provably fair Dice game in the form of FortuneJack.com | 4-Day Dice Signature Campaign - Full Members & Up and FortuneJack.com | New Dice Review - Get paid $50!
Only few days are being considered as vacant. No doubt on why there are many gamblers are attracted to FJ.
(waiting for those reviews)
At the same time, I want to mention that this campaign is different from previous one (higher rates and much more participants but shorter date) and seems they are testing things/strategies in btctalk marketing at the same time.
