Does anyone know how to beat that minigame where you can only walk through each line once? I am talking about that one near Anin Dungeon and Ghaine. I have been trying to beat that forever, but it's so hard.
From trial and error I have gathered that you do not want to cross all but one line of any box then leave it because that will cause you to lose unless you enter that box last.

So, extrapolating from that, the lower middle box has five lines, so because you must cross two lines to go through it, that leaves three lines wich would make you lose, therefore you have to use the middle vertical bar to clear that one, and it has to be the last one cleared.

I'm probably wrong though, anybody else have any ideas?

EDIT: Nevermind, I just read that other thread which said it was impossible >_>
Now I'm stuck on that poison cave place right after Aesir. In the tile flipping minigame there's always one tile I can't flip over. Is this one also impossible?
