It was to make me then not been possible to edge. In many places I did not know whether the parts really belong together or not. In good puzzles that happens to a handful of locations. In this I can not even say how many places the border I have dismantled over time because they do not belong together even though I was sure fit.
Yoda, his lightsaber and the number of Jedi went. But it was also very difficult because I kept coming back to the situation that not a single part of a fit because before that was installed incorrectly in one place.
Cruel it was then but in the areas left and right of Yoda. I did not manage to make this almost monochrome surfaces as one in many, many parts do not know whether they fit or not. Go to 2 edges purely easily and it looks good (Forum and color) but you can find simply no suitable part for the third edge. So on suspected part and back out of the front of the body. This is a tasting game with about 100 same color puzzle pieces.
Something I'm not used to from other brand puzzles (eg Ravensburger). For comparison, last year I have a Ravensburger SoftClick rated. Since there are virtually no two parts where you do not know whether they belong together or not.
