Tally through the Fog
- Fog of war
- Kropki dots
- Region sum lines
The brief
- Normal Sudoku rules apply.
- THERE IS ONE, AND ONLY ONE, blue sumline, where box borders divide the line into segments of equal sum. Distinct segments of the line within the same box count as separate sums to the same value.
- A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are given.
- The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell. No guessing is required.
