Build Your Own Sudoku Grid
(Published on 29. May 2021, 09:38 by jhunter)
-Normal sudoku rules apply where digits cannot repeat in rows, columns, or 3x3 boxes, however, the 3x3 boxes are not given and must be deduced.
-The grid is to be treated as a torus (rows 1 and 9 are adjacent and cols 1 and 9 are adjacent) and 3x3 boxes may cross any "edge".
-Identical digits cannot be a chess knight's move apart (including across "edges").
-Digits in cages sum to the given total, digits on thermos increase from the bulb end, and grey lines are palindromes that read the same from either direction.
Edit: Just to avoid some confusion this is not an irregular sudoku it is just a regular sudoku grid that has been translated horizontally, vertically or both.
Tip: The Edge tool is useful for marking the boxes once they've been deduced!
Solution code: Row 8 (left to right)

@SudokuExplorer Great question! It's just a translation but I'll edit the rules to make it more clear

Is it a translation of a normal sudoku grid or can we have something like this: https://git.io/JGn7W
Edit: I assumed it to be a translation, and the logic flowed beautifully. Thanks for the lovely concept! :-)

@SKORP17 @glum_hippo I'm not sure If I fully understand but they are 3x3 regions and there are multiple ways to do this since the grid is a torus, for example columns 8,9,1 can be part of the same region.

Agree with SKORP - this is a fascinating puzzle but don't call them 3x3 boxes if they are '9-cell regions' :)

Really cool idea. Thanks!

ziemlich unverständlich, es können nicht nur 3*3 Boxen vorhanden sein, das geht nur auf eine Art, also muss es sich um irreguläre 9-er Bereiche handeln, die es zu finden gilt (wobei durchaus 3*3 Bereiche vorkommen können)
