Normal Sudoku rules apply. Additionally:
1. Antiknight: cells that are a chess knight's move apart may not contain the same digit.
2. German whispers: digits along green lines must differ from their neighbor on the line by at least five.
3. Ratio pairs: cells separated by black dots have a 1:2 ratio. Not all dots are necessarily given.
