I just started playing on Roobet recently, maybe about three weeks ago.  I got a great welcome hit of 1000x+ multiplier on Reactionz 2 during their 20k event.  From then on, I always visit and play  on Roobet whenever I got a spare time or extra fund to enjoy the day.  I can say, I really love their instant credit of the deposit so I always set the RBF off and pay a high enough fee to be able to qualify on that instant credit.
