Tickets are invisible for days,but event is still counting down.It upgraded by itself my drop rate of stones twice.Needless to say in over 400 levels of endless since i got 0 stones while playing.Spinning wheel gives u in over 80 % of spins the thing they invented that u didn't need before.Ads r malfunctioning for days at a time.I'not able 2 play 1vs1 for almost a year.It let me only a few times.Just now i passed 5th level on survival mode with a second 2 spare and it still said i was defeated.
