Black Knight
by FullDeck and Missing a Few Cards Open on SudokuPad
Indigestion
- Anti-knight
- Kropki dots
The brief
- Normal Sudoku rules apply. - Cells separated by a black dot have a 1:2 ratio. Cells separated by a white dot must be consecutive. Not all dots are necessarily given. - Cells that are a knight's move apart (in chess) may not contain the same digit.
