Because Seven Ate Nine
There are two versions of this puzzle. The dynamic fog of war version is available only on
Sudokubank
The standard, slightly harder version without fog is available at
SudokuPad
Rules:
- Normal Sudoku rules apply.
- Custom Rule Why is 6 afraid of 7?: In this puzzle, the digits 6 and 7 are never orthogonally adjacent.
- Dynamic Fog of War (Sudokubank only) The grid is partially covered in fog. Placing correct digits will clear the fog from that cell and may clear the fog from other cells in the grid. Guessing is not required.
- Diagonal: Digits on the marked diagonal do not repeat
- German Whispers Lines: Digits on a green whisper line must differ by at least 5
- Renban Lines: Digits on a pink renban line form a set of non-repeating, consecutive digits in any order.
- Region Sum Lines: Box borders divide blue lines into segments. The sum of digits along each segment is the same. Different lines may have different sums.
- Consecutive Kropki: Digits separated by a white dot are consecutive.
- X: Digits separated by an X sum to 10.
There is a great and growing collection of puzzles, setters and solvers on Sudokubank. Hope to see you there.
