Photobomb Sudoku #1

(Published on 22. June 2024, 23:46 by Breadpain)

This 4x4-Sudoku has a unique(!) solution. Unfortunately someone photobombed us while we took the photograph, leaving parts of the Sudoku covered. Nonetheless you can still find the unique solution using logical conclusions only.

Solution code: The solution code is the two bottom rows in reading order (left to right, third then fourth row)

Although the puzzle is simple, it does a nice job of illustrating an issue faced by puzzle setters - how to avoid the necessity of bifurcation, and the need to eventually uniquely resolve ambiguous states.

Es gibt nur eine Ziffer in dem verdeckten Feld, die zu einer eindeutigen Lösung führt.
There is only one digit in the hidden field that leads to a unique solution.
Außerdem könnte das eventuell die Rückennummer eines Fußballspielers sein ;-), ich erkenne ihn aber nicht.

I'm not sure what the logical conclusion was supposed to be, but I guessed the digit behind the guy's head given the shape of the shadow sticking out, which didn't feel like a logical conclusion, but I really couldn't see what else was supposed to solve it from the end state without doing that.
