Fibonacci Sudoku
(Published on 22. November 2020, 14:59 by ICHTUES)
Normal Sudoku rules apply. The arrows are a bit like a Sudoku arrow, if they are not longer than 3 cells; e.g. 853. Not all arrows are given, and a combination may be longer than the given arrow. Additionally there is a diagonal wit the numbers 1-9 and a killer cage.
Solution code: r7 and r8 (18 digits)

Fun puzzle! The English rules are a bit ambiguous. Few points to make it clear for the benefit of future solvers:
1. A fibonacci sequence on an arrow proceeds in the direction of the arrow i.e. the last digit in the sequence will be on the arrowhead.
2. A fibonacci sequence on an arrow can start with any 2 digits in any order and the rest of the numbers in the sequence will follow from there.
3. "The arrows are a bit like a Sudoku arrow" is not helpful. Ignore the concept of sudoku arrows. Following the first 2 points above is sufficient.

This one's not difficult, per se, it just has work to do to get going. I was hoping some nice logic I found at the start would pan out more, but, oh well. Fortunately the work doesn't take long, so the solution is smooth.

Very nice idea and execution. It took time to find the patterns for the 6 length arrows, but then the puzzle opens up. I liked that use of killer cage was to start the puzzle and not just for making puzzle unique at the end.

Thanks for the puzzle! That was fun.
For anyone not clear on the rules, the arrows are Fibonacci arrows where you can start with any 2 digits you want but follow the pattern as listed.
