Telephone Sudoku
(Published on 21. June 2020, 14:40 by RockyRoer)
In the game 'Telephone' one person whispers a secret message to the next person in line, who whispers it to the next person, and so on. By the time the message reaches the last person, it inevitably has been changed, either on accident (because people can't hear or speak clearly) or on purpose (because people think they're funny and like to reveal who you have a crush on and embarrass you in third grade and you never get over it and wind up making sudoku puzzles as an adult).
In this puzzle, a message was started in the red telephone at the top of the puzzle, and transmitted from phone to phone down the page until the bottom phone in purple. (Red, orange yellow, green, blue, purple). Each time, a single digit was changed, and so by the end, all five digits have been changed. You have been given the third message (digits counterclockwise from the top read 56438).
Your job is simple. Determine the beginning and ending message.
In short - standard sudoku rules apply. In addition, each phone is a sloppy copy (partial clone - one digit changed) of the phone above and below it. At no point in the process does the same digit repeat within a phone (that is, phones act like killer sudoku cages.)
Solution code: The original message in red (counter-clockwise from the top) followed by final message in purple (counterclockwise from the top).

Clone sudokues is my favourite sub-genre, and this is like one but with a magnificent twist. What a puzzle!

As others have said, delightful from the description all the way to the last digit. Thanks also for not making it intensely difficult.

Indeed, a very cute idea.
The German name for that children's game where a message is passed along by whispering it into the next person's ear is "Stille Post". (=silent mail) This is actually very fitting in this case, as up till the 90ies, the German post office (=Deutsche Post) was where you'd apply to get your landline phone installed.
