- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Rotational 10-sums: Any pair of cells that are images of each other when rotating the grid by 180 degrees around the central cell (R5C5) must contain digits that sum to 10. If for example, R1C2 contains a 7, then R9C8 must contain a 3.
- Little killer: Digits on a marked diagonal sum to the little killer clue outside the grid.
- Zipper line: On the zipper line (purple with the circle in the middle) digits at an equal distance to the centre must sum to the digit in the central cell (R5C4).
- Renban line: The renban line (thicker, purple without a circle) must contain a set of consecutive non-repeating digits in any order.
- Nabner line: The yellow/golden Nabner line may not contain consecutive digits (anywhere on the line). If a 2 lies on the line, it may not contain neither 1 nor 3.
- Arrows: Digits on an arrow sum to the digit in the circle from which the arrow emerges.
Clarification: In case, there is any confusion for colourblind person: The zipper line is on the left hand side starting in R3C2 and ending in R8C2, the Renban line is on the right hand side starting in R2C8 and ending in R7C8 while the Nabner line is in Box 8 in the bottom.
Here you can solve the puzzle online:
Solution code: Row 5 from left to right (9 digits in total)

Thank you for this interesting puzzle, dear sujoyku! For someone who is not used to these rules, it is not easy. But it is really beautiful harmony when in the end one nummer teleports his friend to the equivalent place. I really enjoyed solving it! :)

Neat puzzle! Usually this kind of rotational symmetry is a consequence of the rules and clues, so it was cool to experience the reverse, where requiring the symmetry resolved the clues.
The logic was pretty straightforward if you know these clue types well. I'd put it at 1.5 stars.

Thank you for your comment, softie! I am glad that you liked the puzzle. The rotational constraint definitely is key. Also thank you for sharing your take on difficulty. I think it should be a 2 stars for most, but really depends on prior experience with similar puzzles.
Kind regards, sujoyku

Gorgeous! I couldn’t figure out the break-in - but suddenly, I asked the right question about the zipper line, and whoosh - the puzzle collapsed like a house of cards. Loved it!

Thank you for your comment, dingledork! The zipper line was one of the ideas I was most fond of when setting the puzzle. So I am glad you liked it as well and it helped you to a smooth solve.
Kind regards, sujoyku

I love how the puzzle resists for a while but when it gives in, it just explodes with all sorts of interactions all over the place.

Thank you for your comment, alexsmart! I can relate with what you are saying: The rotational constraint is so strong that once you have a little, you soon get a lot more. I am glad that you liked it.

Really neat logic! I liked the break in. The middle got a bit tougher, and then it really started to flow!
