Thanks for your reply,
Event "first top-up, 2 times value", which is released on home page, was not annouced in game. Many players like me did not realize that, so they lost the chance to maximize their top-up (instead of 99$ top-up, I just top up $15 because I did not realize that). My friends even did not know this event is exist. That was unfortunate because if snail introduces clearly in Shop, more and more player will maximize their chance.
