- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Index lines: Each turquoise line is an Index Line, i.e. the digit in the Nth cell along such a line (starting from the diamond) indicates the position along the line where the digit N appears. For example, if a diamond cell contains a 3, the third cell along that line must have a 1.
- German Whispers: Adjacent digits along a green line must differ by at least 5.
- Renban: Each purple line must contain a set of consecutive non-repeating digits in any order.
Here you can solve the puzzle online:
Solution code: Row 4 from left to right (9 digits in total)

Great indexing puzzle, and I enjoy all of them. I just want to say that I am cooped up at home recovering from surgery in an area that is a frozen wasteland. Great sudoku setters like you, sujoyku, are a Godsend in such times.
