Play on SudokuPad

Normal Sudoku rules apply.

The digits separated by the white dot have adjacent values. Not all possible dots are necessarily given.

Cells in the same position in two boxes (e.g. r1c1 and r4c7) may not contain the same digit.

XYZ means 'Row X Col Y is Z.' If XYZ, then YZX is also true.

Solution code: Row 9

I loved this puzzle DESPITE not actually being able to complete it! I was able to catch my first mistake and back up, but clearly made another that didn’t present itself until I nearly had the grid completely filled.

I really enjoyed trying to figure out a system of notation for this. At first I tried coloring groups of connected cells, but actually restarted the puzzle because that got out of hand. Realized that two remaining possibilities in the same box were the most powerful and leaned heavily into that. And finding that the upper left corner was limited and running the possibilities in box 9 was a fun change in my technique.

Maybe I’ll give it one more go?

Quite fun! I got the truths, but my brain was having difficulty transposing XYZ to YZX, so I ended up building a quick calculator in Excel to automatically fill transposed values in as I entered them.
