Reading Between the Lines
(Eingestellt am 27. Januar 2026, 18:29 Uhr von ul-Rhymm)
Sudoku: Each digit, 1-9, appears exactly once in each row, column, and 3x3 region.
Double Arrows: Digits on a line must sum to the same value as the sum of the attached circles.
Between lines: Each digit on a line must fall strictly between the digits in the attached circles.
Some clues in this puzzle are double arrows and some are between lines. It is up to the solver to determine which is which (some may satisfy both constraints).
Colored lines are cosmetic to clarify how arrows cross and do not indicate type. The grey line in row 3 connects R3C5 and R3C8. The maroon circle in R3C6 appears on the line but does not interrupt it. The same is true of the symmetrical pattern in row 7.

Lösungscode: Row 1, Left to Right.

Wow that was quite a journey. Maybe not quite as hard as the 5 star rating suggests, always fair, just had to ask the right question.

Excellent puzzle - took a while to work it out. Was fascinated to see how it disambiguated given the near symmetry.

Absolutely brilliant. I found several deductions I have never seen before.
