Normal Sudoku rules apply. Green lines are German whispers lines; adjacent digits on these lines must differ by at least 5. 159 rules apply: Each digit in column 1 indicates the position of 1 in its row (that is, if R3C1 is a 6, R3C6 is a 1). The same is true in columns 5 and 9 of the digits 5 and 9, respectively.
First 159 I've published here, so any feedback is appreciated!
Solution code: Row 7 followed by column 3, no spaces
