How does it work?

It takes up to a week to receive it.

Can you speak Spanish? I know you're from Poland but maybe you do know.

As Yatterman already said, the guy has one week to send you the gift. If he doesn't, mark it as non received here.

He can send it by email or add you to Steam. Check both.

Ten twoj google translator to tak tlumaczy ze bog wie o czym chodzi.

That in the end I do not know whether to mark the giveaways ---> view from and where I won -> Received Gift? and select yes or left blank?

If you have won, just wait for him to either add you and trade you the gift or tell you the code. Either that or an email will come.

I'm waiting until I can code. How do I specify that I get to not let it 'do not check and wait 1 week and then the selection is not. Well I say?

Nie używaj translatora bo nikt tego nie zrozumie.
