Shifter Lines 120: Masyu

(Eingestellt am 7. März 2026, 15:00 Uhr von gUBBLOR)

I've been doing a bunch of masyu recently, and I decided to mix it with some sudoku. The previous puzzle in the series:
Shifter Lines 119: Deconstruction

All my series:
Equality Cages
EquaLite Cages
Shifter Lines
Shifter Dots



Rules:
Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Masyu: Draw a single non-intersecting loop through the centers of some cells that passes through every circle clue. The loop must turn on black circles and pass straight through the cells on either side. The loop must go straight through white circles and turn in at least one of the cells on either side.

Shifter lines: The entire masyu loop is a shifter line. Adjacent digits within the same box on a shifter line share both parity (even/odd) AND polarity (low/high). Whenever the line enters a new box either the parity OR the polarity shifts, never both. Shifter lines can never have 5 on it. Digits may repeat on the line.

Kropki dots: A white dot between cells indicates cells with consecutive values. Not all dots are shown.

XV: Adjacent cells connected with an X must sum to 10. Adjacent cells connected with a V must sum to 5. Not all X's or V's are shown.

Cells connected by a dot or an X or a V are either both off the loop, or both are on the loop and the loop goes through the constraint to the next cell. When the loop goes through a constraint this act as a box border for shifter line purposes.
