App doesn't even work. After download and install, I open the app and checked on the checkbox over the terms of service. Yet it won't even continue past the loading screen as it keeps showing pop-ups stating, "Oops! Some permissions are required to run the game." Well, I was never given the option to turn them on and even went on the app info and saw the permissions field being greyed out. So yeah, waste of time installing thanks to this bug. Uninstalled.

Impossible to use. It is necessary to watch adverts after any button press on this app, which would be annoying but passable (given this is a free app) except that every advert (and I've seen several different companies now) cause the app to crash. So you start the app again, are forced to watch another advert, then it crashes again. Also, the adverts don't even have a mute option, so you wouldn't be able to use the app in public (if it worked, which it doesn't).

Untrustworthy, so uninstalled. You can 'save' grids to be submitted later. Good idea. But the prog just keeps losing them, including once when I had 87 saved, which requires sitting through 87 adverts. A week or so after I first used it, it made me sign in again and had list all my progress. Technically just not good enough. .
