Android emulator
An Android emulator is a bit of software designed to make Android programs run on a Windows operating system. Why do that? Well, either for the hell of it
or to run an Android app (or game) at a larger size than it is on a small tablet or telephone screen.
I installed an Android emulator called 'BlueStacks' as an experiment and it seems to work well apart from it taking a while to load. The software uses Android 7 at present but I expect there will be updates. Playing 'Word Chums' on a Windows computer seems strange. It's normally only available on Mac and Android.
