There an unwinnable level in explosive puzzle which makes you unable to play the event. There's no way to report this issue either. Terrible/nonexistent customer service. I've been playing for quite a while, 2 years, this was a much more fun game before it became what it is today. Now they make you pay real money to enjoy/complete 95% of events. Originally it was not. Very disappointed to see this. I'm not the only one who thinks this way. It's become a 2nd job. No one wants that.
