The fact that the puzzle is immediately covered up as soon as you solve it, thereby not allowing you to look at it and enjoy it, takes all the fun out of it.
Hi, thanks for the feedback. I don't understand how it gets covered? It's true that jigsaw pieces borders fade and you see only the original image again. You want to see borders of pieces, and to have a look-and-feel of the completed jigsaw puzzle, if I understood correctly, right?
