YouWave for Android 4.1.1 – The Android Emulator
YouWave is a software which is used to run the android apps in your computer and its also used to play games i.e., android games with the Desktop or laptop using YouWave .Playing with the Android emulator on your computer is a pretty geeky endeavor, but YouWave makes it easy to accomplish on your Windows PC. If you can download and install a Windows program, you can have an Android virtual machine running on your desktop in just a few minutes.
Probably this is the best alternative for BlueStacks.But YouWave won’t launch most of the games like Temple Run,Subway Surfers etc. while you can play them on BlueStacks.
