Was fun while it lasted. No way to play the events as a free player. I tried to play the latest event (ended Feb 14) and was approaching the final keys but even after spending $15 still had more than a days worth of time I would have needed to finish getting the last two keys. That's not even getting started on the ranking system for the events. No possible way for a free player to get past the top 50. I've decided to uninstall. You got my $25 for the month, I paid for no ads and the extra gems.
