Rules:
- Normal sudoku rules apply.
- Windoku rules apply : the four 3x3 shaded boxes must contain all digits from 1 to 9.
- Modular lines: every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}.
- Digits along lines may repeat if allowed by other rules.
- Digits in a cage must sum to the total given in the upper-left corner.
- Digits joined by a white dot must differ by the given difference.
Solution code: Row 6 followed by Column 4 (left to right, top to bottom, 18 digits without spaces)
