Fear [Fog, X-Sums, Ambiguous Pairs]
(Published on 2. December 2023, 18:05 by Malrog)
This is my first "Fog of War" puzzle, and I wanted to use the fog for something more than just directing the solve path. I hope I have achieved this, and I'd love to hear about your solving experience in the comments.
Rules
Normal sudoku rules apply. Placing correct digits will clear the fog from surrounding cells.Grey diamonds separate two adjacent numbers that are either consecutive, or in a 1:2 ratio, or sum to 5, or sum to 10.
All numbers outside the grid are X-Sum clues. This number is the sum of the first X digits in the row or column, where X is the digit nearest the clue.
Solve on SudokuPad.
Solution code: The digits in column 4, top to bottom.

Loved this puzzle, might be one of my favorites. A lot of logic that took me a long time to figure out, but I enjoyed every step. Thank you for sharing :]

A fine and interesting puzzle with some clear thinking required.

The break-in took a second for me because I had to figure out that I was responsible for placing the X-Sums myself, but after that, it was a wonderfully fun puzzle.

Nice puzzle! I enjoyed the logic around the ambiguity of the diamond clues. It allowed for some surprising results!
