I've used several Android Emulator since 2015 and what I am currently using now to play mobile games on PC/Laptop is Bluestacks. I prefer Bluestacks than the others because it has higher android version thus it is compatible to play some games which require a high android version. Also, it has its own application market to download the app you cannot find in Playstore. Speaking of its safety, I do believe that it is SAFE. That is guaranteed by my experience. Never in my life I've encountered a detrimental effect on my account in different games: I wasn't banned.
