Nordschleife (Bosnian road/multiples pairs sudoku)
(Published on 29. November 2024, 20:31 by Qodec)
- Sudoku: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Bosnian road: Draw a 1-cell-wide loop of orthogonally connected cells, which does not branch or touch itself, not even diagonally. Circled cells are not on the loop, and the digit in a circle indicates how many of the up to 8 surrounding cells are on the loop. The cell with the rectangle is on the loop.
- Multiples pairs: For each pair of adjacent digits along the loop, the larger digit is an integer multiple of the smaller digit. Example: 9 is an integer multiple of 1, 3, and 9, but not of the other digits.

Wow that was quite a crazy puzzle, but in a good way. Some parts took a while to make progress, but my head was shaking at how it even resolved uniquely at the end, that was quite magical xd
