The Robin Hood Incident (Broken Arrows)

(Eingestellt am 23. Juli 2021, 11:48 Uhr von RobK)


The story goes that the legendary Robin Hood once fired an arrow perfectly into another, splitting it. Here's an arrow sudoku with broken arrows.

Solve on Penpa

Rules: Normal Sudoku rules apply. Also, the digits on an arrow add up to the digit in that arrow's circle. Arrows and circles have to be matched by the solver - no cell on any arrow shares a row, column or 3x3 box with its circle.

To clarify: if an arrow with total 6 shares a box with a 6 in a circle, that cannot be the circle that goes with that arrow. Penpa only checks the digits, not the matching. Note that the cross in R1C8 is a one-cell arrow. ie: The digit in that cell must match the digit in its respective circle.

Thanks to CilantroGamer, SSGranor and Mr.Menace for testing.

Good luck and happy solving!

Lösungscode: Row 9, then column 9. 18 digits, no spaces.

Crazy puzzle. Opening logic was really cool but very tricky for me, definitely harder than 3*. Very interesting puzzle.

It's brilliant! Exactly the flavour of puzzle i live for - looks impossible, but turns out to be really smooth after the initial shock wears off.
