I have a chromebook, and you can play- a limited version- with the app from the google play store. However, it does not include multi-player games (such as Alt Shot< Match Play); head-to-head only in coin rooms.
For the full game, you need a Windows computer or a Mac. I purchased a cheap Win10 laptop for the sole purpose of playing the WGT "Launcher" version. It works fine, game play wise, although the fixes needed are amply described in the forums. WGT is "working on it".
