Is it true that in Sweden there are piles of ballots in the polling station for each party and you can draw a ballot for the party you are voting for ?
So, basically everyone knows for which party you are voting, depending which ballot you take (unless you take ballots for every party with you into the voting booth) ?
You asked this question four years ago as well Tender, I'm disappointed you do not remember.
The answer is yes and yes. People who want to keep their vote secret bring their own ballot papers or take one from every party.
Isn't this a terrible waste of paper you might ask. Yes it is, but Sweden has a very big forestry and paper industry so see it as one big subsidy every four years. 
I cannot remember everything ... 
But thx for the answer. Yes, terrible waste of papers indeed.
It works the same way in Spain. You know which party will win in your college before the vote count starts.
