With the puzzle... If someone can get a picture of the puzzle...
I think that there were 3 peices that are blank (EG, they had no track in them for the metal ball to roll)
To change the last 2 peices round (Eg like the peices 14 and 15) You would need to swap the places of 2 of the blank tiles... There are a few puzzles like this, where it can 'flip' EG, from a seemingly unsolvable state to a solvable one...
This can only happen if 2 (or more) of the tiles are identical. (And if im right, they have to be an uneven number of places apart from each other) Eg on a chess board, one would have to be black, the other right...
So for him, the top 2 peices in the top right would have needed to be swapped (3 and 4 if im correct)
Can the Krypton factor staff confirm this?
Thanks
