When I provide given digits, I often provide one of each, or all odd digits. This time, it’s the first nine digits of pi. They’re shifted a bit off in each row, because the Disjoint rule would otherwise not allow the double-1 and double-5.
Rules:
Normal Sudoku rules apply.
Digits on each hollow pink line form a non-repeating set of consecutive digits in any order.
Cells in the same relative position within each box contain different digits.
Estimated difficulty: 2 out of 5
