Disclaimer: This is unsupported. I mean, it's even less supported than GAM itself which is unsupported. So it's really unsupported. Running GAM on Android and Chrome OS devices may not be reliable and could break at any time. If and when it does, you get to keep both pieces.
It's possible to run GAM on your Android and Chrome OS devices
which support Google Play Store. It's not very fast, can be a bit cumbersome and may not always be reliable but at the same time, it may save you when you're on the go and need to run a quick command.
I've had luck running GAM on a Nexus 6P, Pixel XL, Asus Chromebook Flip and Nexus 7 tablet.
