I can't find coin, I have looked everywhere including bakery floor and all around the jukebox :-*
Spoiler
its definately on the bakery floor and not around juke box, I think it was somewhere on the left hand side of the screen
Thank you Jane, after much searching on the left side of the floor and not finding anything I realised my screen on monitor was over to the left so after centering it I finally found the coin and was able to complete the game and find the secret puzzles. I really enjoyed this game but would have been totally lost without without this hints forum. Thanks again
