Just putting this out there for future searchers for why there are no Video - Tapjoy - Survey buttons on their Amazon device using the Amazon app store to install WGT.
The Amazon App Store version of WGT is incomplete! The game itself is okay, but only the RevU option is available for earning credits. To get the Videos, Tapjoy, and Surverys, you must install WGT from the Google Play Store. Amazon doesn't want Google Play store on their device, so it's not simply select and install.
Need to download 4 files. It's not complicated to install Google Play, just more of a pain than it should be thanks to Amazon. Directions must be followed to the tee. Hope this helps a few and good luck.
