Fog Puzzle #3
- Fog of war
- Kropki dots
- Whisper lines
- Renban lines
The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Fog rules: fog obscures most of the grid. Placing a correct digit in a cell removes the fog from surrounding cells.
Lines in this puzzle do not branch or cross themselves.
Purple lines are renban lines: digit on a renban must be a non-repeating set of consecutive digits in any order.
Green lines are German Whisper lines: cells which are adjacent along a green line must contain digits with a difference of at least 5.
Digits in cells separated by a black dot must have a 1:2 ratio. Digits in cells separated by a white dot must be consecutive. Not all possible dots are necessarily given.
