My tablet have a 2 core cpu, 1gb of ram, android 4.4, and a 7" scren, but google play say, my device is not compatible with the game. So what is the minimum req. for android?

What model is your tablet?

Galaxy tab 3 7.0

I know, it isn't a flagship, but not that weak

I have the same model, I have a friend with a Tab 2 and he can download it....grrrrr

What the heck??

is your tablets Wifi only or can you use sim cards in it?

Mine is wifi only

I have a tab 2 and can't download it either.

I know people with both wifi only and cell and still can't get it. Also seems a strange point to make it wifi only when the download specifically says to use wifi since its a larger download.
