Modular Lines
(Published on 7. December 2024, 17:41 by sudoku_explorer)
- Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
- Modular Lines: Every 3 consecutive cells along a modular line must contain a complete set of residuals modulo 3. i.e: one from (3,6,9), one from (1,4,7) and one from (2,5,8).
- X-Sums: A number outside the grid gives the sum of the first N digits in that row or column, where N is the digit in the cell closest to the given clue.
- White Dots: Digits seperated by a white dot are consecutive. Not all dots are given.
Solution code: Row 5 (9 digits, no spaces)
