So I was having the same issue as a lot of yall where the play store either wasn’t showing the game to download or would say it was incompatible.  So you need to go into your samsung internet browser (NOT CHROME BUT THE SAMSUNG BROWSER!!) now once you open the browser input this link in and you should have no problem downloading the game.

If this doesnt work for yall,  idk what to tell you since it was the first thing I did and it work!

Thank you for this!!!
I have a Samsung Galaxy S5 and was unable to download from the Google Play Store because it said it was incompatible, but the Galaxy Store worked like a charm.
(In my case, I just used the Galaxy Store app that came with my phone, but the theory is still the same.)
