How do you buy games on nuuvem?

Use Hola Unblocker on chrome and set your region to brazil then buy the game, and disable hola when you reach payment

You add them to your cart and pay with PayPal or sth else.
If you get a "not available in your region", simply use a proxy. Game should activate just fine, it worked with Castlevania LoS.
Use Google Translate, I don't speak the language myself.

You register with an allowed email address (for e.g. gmail), then add stuff to your card, make sure it doesn't say it's region locked. Then go ahead and pay (via paypal for e.g.). That is all.

I use ZenMate or proxies, it works jusst fine.
