In your opinion, which Zelda puzzle really stands out for you? Which puzzle did you find to be particularly clever, fun, and so on?
For me, it's the ice block puzzles hands down, which have appeared in OoT, MM, MC, and TP (off the top of my head). There is always a lot of thinking ahead when trying to solve one of these puzzles, since you carefully have to plan your moves. I guess it's sort of like chess in a way. Another thing that intrigues me with ice block puzzles is the fact that the law of conversion of momentum is violated (that is, after a block hits another, both blocks don't move). Ahhhh, video game logic! I'm especially fond of the series of ice block puzzles to get a Heart Piece in Twilight Princess.
