Irrwisch Sudoku: Sandwich
(Published on 22. May 2023, 11:30 by Gliperal)
Normal sudoku rules apply.
Clues inside the grid represent the digit that should go in that cell. Clues outside the grid represent the sum of the digits between the 1 and 9 in that row or column.
All clues are encrypted: Every digit within a clue has been replaced with either a ? or a letter. The letters A, B, C, and D are each an irrwisch, which represent a different digit every time they appear. Two-digit clues may not start with a 0, but one-digit clues may.
Example:
Solution code: Row 4, Row 9

It was difficult to find the right questions to ask but the logic flowed nicely once you do.

I found it very difficult to wrap my head around this one, especially at first. Excellent puzzle!

Amazing puzzle with way more deductions than there are clues.
