Fog Sudoku #37

(Eingestellt am 22. August 2026, 08:01 Uhr von Sudonym)

Fog of war sudoku. Mixed rules. Link to puzzle. sudokupad. There is a video solution and more puzzles on youtube channel "sudoku spot" video solution Rules: Normal sudoku rules apply. Black dots separate cells in the ratio 1:2. White dots separate consecutive cells. Cells adjacent to an X add to 10. Opposite corners of 3x3 boxes sum to 9, 10 or 11. Cages are Psycho look-and-say cages. Numbers in cages point to a 3x3 box number....so a number 5 would point to box number 5, number 8 points to box number 8. Go to that box number and find the same position as the number in the cage. This is where the look-and-say numbers must be. Numbers in the top corner are look-and-say values telling how many of these numbers are in the pointed cells. For e.g. 38 would mean 3 of the cells in the cages point to an 8. If there is for e.g. 18 in the top corner of the cage but 2 numbers in the cage then only one of them points to an 8. (I have made a video explaining look-and-say cages on youtube channel "sudoku spot". Rules are not as hard as they seem but are easier to explain in a video rather than in words) video explaining psycho look-and-say cages

Agree the ruleset is difficult to write, even if once understood is straightforward.

The only thing that got me on this was that the fog and Psycho look and say, seemed connected, but the rules on opposite corners seemed a little arbitrary. (And hence easy to miss)

For ref, my take on the rules wording would be
Cell X in a cage "looks" at the digit in box X in the same relative box position as itself.
Cages are Psycho look and say, indicating how many of those cells look at a specific digit, eg 38 means three of the cells in the cage look at an 8

I enjoyed your puzzle, but I found the explanation of the ruleset very confusing and needed to watch your video to understand where I went wrong. My initial interpretation was that, if there is a 6 in a cage, it is pointing to cell 6 in box 6. I think the ruleset would be more clear if, for instance, it said "A value of N in a cage points to the cell in the same position in box N. For example, if a cage in the top left corner of a box has a value of 7, then it points to the cell in the top left corner of box 7." That said, I agree it's a tricky ruleset to describe in words, and you might wish to consider including a diagrammatic example, or a direct link to your solve on YouTube. Thank you :)

Reply: thanks for the different explanation, hopefully that will help others. I have put a link to the youtube video explanation plus one to the puzzle solution thanks very much to Igastako for helping.
