(Published on 13. March 2025, 16:06 by fredchen)
Rules:
- Standard sudoku rules: place the digits 1-9 in each row, column and cage.
- Standard anti-knight: digits on knights-move (in chess) away can’t be the same.
- Standard palindrome: digits on a grey line must read the same in both directions.
- Black Kropki dots: digits separated by a black dot are in a 1:2 ratio.
- Withe Kropki dots: digits separated by a withe dot are consecutive.
- False Arrow: the digits along a purple arrow can not sum to the digit in the bulb end. The bulb can add to something greater than 9.
For better clarity enable: Draw arrows above lines

Very unusual puzzle. I have played wrogns before but this one felt quite different. Nicely done. Quite enjoyable to solve. Thank you

By law, every wrogn and semi-wrogn puzzle should have a 100% rating. This one is no exception.

Solution code is finally correct

I‘m really sorry about the solution code. I double-checked a dozen times and on my computer the solution code is working so I don‘t know where the problem is

CitrusGremlin the arrows don‘t need to sum to a valid sudoku digit so the arrows can have a total sum of 10 or higher.

Hope the solution code is working now

CitrusGremlin it cannot sum to 10 or higher (as it is not a valid sudoku digit)

Question about the rules, do the arrows need to sum to a valid sudoku digit? Or can I have an arrow that sums to 10 or a even higher? I've reached a point where I can't progress without assuming the former but I'm not sure if that's valid logical thinking or not.
