Play in Sudokupad

Place nine 3x3 box regions in the grid without overlapping. All clue cells must be included in a box region. Fill all cells outside of regions with 0 for the solution check when you finish the puzzle.

Place the digits 1-9 in each region. Digits may not repeat in a row or column.

Limitations: Digits do not repeat on quad circles or on any same colored line or same colored dot (rules 1-8 below).

1. The four digits in a quad circle appear in the four surrounding cells.

2. Box borders divide a blue region sum line into segments with the same value. The value of a segment is the sum of its cells.

3. A purple Renban line contains a set of consecutive digits in any order.

4. Adjacent digits on a green German Whisper line have a difference of five or more.

5. Adjacent digits on a red line alternate parity (odd/even).

6. Adjacent digits along a gray sequence line have the same difference. Separate lines may have different differences.

7. Black dots connect cells in a 2:1 ratio.

8. White dots connect consecutive digits.

The grid is partially covered in fog. Placing correct digits may clear fog somewhere in the grid.
