Art. 20. São vedadas as caixas de recompensa (loot boxes) oferecidas em jogos eletrônicos direcionados a crianças e a adolescentes ou de acesso provável por eles, nos termos da respectiva classificação indicativa.
Not as far as I can tell. This translates to "Loot boxes offered in electronic games aimed at children and teenagers or likely to be accessed by them, in the terms of the corresponding age rating".
You can argue that "offered" here specifically implies "offered for purchase", but... I mean, my Brazilian Portuguese isn't perfect, but I don't think that's explicitly the case, the word means what you think it means in English. It'd be a problem of hermeneutics at that point.

I wrote a first response referencing the one mention I had found of loot boxes, but you are correct, I missed that they did include one in the definitions section.
So yeah, you are right, they do define it as paid. Carry on.
