If you have a PC/Laptop and want to play Android games on it for free and that too legally then download this software called “bluestacks”. It’s currently available to download for free(Link is below). It currently supports windows 8/7/vista/xp, Mac OS, it’s in beta phase right now but it works without any problems. Its actually an OS inside OS meaning that you are running Android on top of Windows as in emulation inside a player, the apps are not running natively on the windows which means they will not run properly on PC with weak specs. So to emulate properly you will need a powerful PC/laptop at least something with a dedicated GPU. Although you can still try with any PC/Laptop that you have.
