Bests & Worsts Reviews from Amazon

I find that a better processor will help in the app not crashing. I have the kindle fire hdx 8.9 which runs very well and smooth with all apps. I feel that if your processor is 2gh or higher that it will run very smooth. The game events are perfect. I wish it didn't have to take so long to upgrade health and attack especially when we have other missions to do that need to be done to earn the event currencies.
