Shifter Lines 109: Between the Shifter Lines
(Published on 26. January 2024, 05:04 by gUBBLOR)
Equality Cages 122 x Shifter Lines 108: Vortex
Equality Cages 124 x Shifter Lines 110: ᚱúᚾᚨᚱ (Runes)
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.
Shifter lines: 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 lines.
Kropki dots: A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are shown.
Between lines: Cells along lines between two filled circles must have values between those in the circles. Digits may repeat on between lines.

I wasn't sure if, according to the rules, the between lines are strict - e.g. if 1 can be considered to be between 1 and 3, say. It says that digits can repeat on the between lines, and I know that usually between lines are strict like that (1 is not between 1 and 9)...
Not sure if there's a way to solve without this assumption. I tried and couldn't solve it until I decided to try assuming this reading of the rules, and then it flowed beautifully.
At any rate, a great puzzle.

I somehow managed to break the puzzle the first time I went through it, but after restarting all the pieces fell together like a charm! Very nice!

Amazing puzzle! Your shifter line series is great. This really made me think, but was not at all frustrating.

Beautiful integration of shifter lines into between lines. Excellent construction.

Quite liked the concept of between lines and shifter lines on top of eachother. Made for a fun solve!
