Puzzle Master Achievement
Solve all Puzzles without using the Skip button.*MISSABLE*
As the description says, you need to solve all puzzles without ever using to skip one. Just to clarify, this only impacts minigames; Hidden Objects Puzzles are not included in this achievement (and you can't skip HOPs anyway).
Aside from the lockpick puzzles that could trip you up if your trial and error doesn't work, all other puzzles in this game have virtually no difficulty. You will likely be able to solve them all yourself in a minute or two, but if you ever get stuck or just prefer a walkthrough, refer to the Last Stand (60G), since it includes all puzzle solutions.
