Clash of Clans is a game from the Finnish company Supercell created to be played on mobile devices, not for PC. However, there are dedicated people behind the developers' backs to adapt the title to play on PC. Read on and find out what it's all about...
Unfortunately there is no version of Clash of Clans for PC. Instead, what has been used for a long time is an emulator of the Android environment to use on your computer that allows you to get all the applications from Google Play in the comfort of your computer.
Thus, you only have to download your favorite emulator among those that exist, and then open your google play account with your Google user, and download Clash of Clans from that interface.
