I am thinking about this question:

enter image description here

The public solution is


But I think I have another working solution, but I wasn't able to find any validation.

I think it's

enter image description here
The red marked fields added up build the green field. So the whole pattern looks basically like a C. And when we use this pattern to get ?.
enter image description here
We end up in A.

Did I miss anything or is this also a valid solution?

    $\begingroup$ As your answer is only based on a "single" observation, usually that might be incorrect. You should justify again with other observations. For example, by taking the third L from the third row (along with your solution) + R1C1 to get R1C3, which in this case, it doesn't match. Thus your solution, unfortunately, might fall into an opinion-based solution and usually it's not the correct one as it can be arbitrary. $\endgroup$

  • $\begingroup$ @athin Thanks for your answer. Yes, the "single observation" explanation makes sense. $\endgroup$

    $\begingroup$ Such puzzles are extremely terrible in the first place, because they contain too little information to make the 'official solution' the simplest. Your solution shows this! (So I upvoted.) See this post to get a rough idea of how to quantify this notion. $\endgroup$
