sorry but your post is a tad confusing......are you saying that an app is downloading games from inside of the app? or that the app is not downloading these games? can you be more specific on what is going on? what app are we talking about? and do you want these slot games? or you do not want them?

 

I have a Moto e6.
Personally, I would stay away from everything Google that you can.

Try using Uptodown instead.

My guess is that you need to allow permissions to this app.

Storage?
Install apps?
Things like that.

 

You may not have enough storage to download it. This phone has next to no storage.
