Correct. Game is shut down and unplayable

But you can still install the game on google play store tho?

I mean in my google play it is still installable.

The google play version is now just a splash screen that says something like "Thanks for your support"

If you want the "Gallery Mode" version, you need to install from a different app store like Amazon app store.

Cool. what's gallery mode?

It lets you listen to the background music and view the non-HD images for all the cards along with one or 2 of the card quotes for each card.
