Playing Clash of Clans on your phone is fun but when your phone runs out of charging while you are pushing or farming can cause great stress. To eliminate this problem you can play every Android game on your PC or laptop. While playing on PC or laptop you don't have to worry about battery drainage. There are many Android emulators but I personally recommend BlueStacks as it is light weight and runs every game smoothly. You can also use Auto Hot Key or auto farming bots on BlueStacks.
You can download Clash Of Clans along with BlueStacks from this link Click here
After downloading just install the Bluestacks app player. Just login your google account and enjoy the game on your PC.
