As far as I can tell, you can’t get it free yourself, you can only gift it to another player for free… That is a weird way of doing it.
Nah, I got it for myself fine with ‘Get It Free’ button. Though I asked google and someone says some people have problems claiming it with client but have none with site. Only problem I had is their system is too sublime to say me I’m trying to recover password using wrong email.
Sure enough. I was trying to do it through the client. Website worked just fine.
