Hi all....i have a gold tessarisis with the silver buttons, ive decrypted the clues, watched andrews video and sketched diagrams of the puzzles mechanics as i understand them but still have some confusions....the bar on the top do i have to push it all the way down to make the slider move? I know that one of the wheels has to be turned so the gravity bar can slot into it but how can you tell when its done as i put the puzzle to my ear while rotating it and cant seem to be able to distinguish between the clicks i hear.... does anyone know which is the first wheel to turn? The clues are vague about the matter...i know that a buttom on the bottom has to be sunk in to open the puzzle but confused....the ramisis was easier to solve as the copernisis too....if anyone has any ideas how to begin....ive had mine for about 5 years or so and still not sure where to begin...i have an idea of what is happening but not what starts the sequence...thanks
