I'm curious, because I replayed a favorite game from a few years back (reloaded from my Purchase History on BF), and I could swear one of the puzzles had been changed. It was a "tangram" sort of puzzle and I remember it as being pretty pesky. I had to sit down and draw the pieces, cut them out and manipulate them for quite a while to achieve the solution. This time, though, when I played the game, there were little clues on the puzzle itself as to the final arrangement of the pieces and I finished the puzzle in about a minute. Hence, the question.
