I have no idea. I am beginning to wonder about that as well. I am hoping that King Games will be generous enough to share the Season Of Joy by giving us more boosters this Holiday Season. Don't you agree?
The Fantastic 5 Competition is all messed-up and does not keep track of the games anymore. Sometimes it works, sometimes it doesn't. Keep on publicly posting on this in the Community so your voice can be heard. I am not sure if posting on my wall would make a difference since not everyone sees this.
My iPhone was sent to Apple Support for Battery Repair Service in California last Wednesday. Since it is Thanksgiving Holiday Week, shipping takes longer than usual even with the overnight delivery. This was my best source for boosters. I don't know when I am getting this back.
Currently, I am stuck on Level 5582. I still have Levels to complete but I am not getting any boosters right now that I am only alternately playing thru my Desktop, Laptop and the Facebook App. The Facebook App is worse of them all. It does not have Build-A-Bot or Space Dash Challenge. I am sure you know that without boosters it is hard to move up beyond level 5000. I share your frustrations. I am hoping King Games would be more charitable when it comes to Boosters this Holiday Season. Let's just hope for the best.
