There are many ways to run Android applications on the computer / notebook. You can use Android emulator, Android-x86 installer, Android on Intel Architecture, and the easiest way in my opinion to run Android Apps is by using the BlueStacks.
With BlueStacks you can easily run your favorite Android apps on your computer. BlueStacks can be installed on computer using Windows or Mac OSX.
After Bluestacks installed on your computer, run it , search the app you want, download and install , then play it.

Run the installer (online installer), easy steps, follow the wizard.
