Shifter Lines 105: Phistomefel? Who's that?!
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. A white dot between cells indicates cells with consecutive values. Not all dots are shown.
X: Adjacent cells connected with an X must sum to 10. Not all X's are shown.
Fog of war: The grid is covered in fog. Placing correct digits will clear the fog from the surrounding cells.

Lovely puzzle! I feel like it's closer to 2 star than 1

I was stuck in the first box for a while and once I got out of that, it was smooth. Good level of challenge for me. Thanks!

Great puzzle - really enjoyed it! I came across this a while ago but hadn't done any shifter lines puzzles yet so skipped it at the time. But after doing a few of your others I tried this and found it to be a really fun, smooth solve.

I am so glad I came back to this one!
I thought I was missing something when I kept getting stuck. After the update to the update, this is really a lovely puzzle.

Phew, wondered why I was stalling out on a 1 star in boxes 4,5 & 6. Many thanks gUBBLOR for your great puzzles.

While updating the rules yesterday some of the clues got lost from the puzzle. I've put them back in now, apologies to anyone who struggled because of it.

Verry nice concept those shifter lines. Easy but nice solve this puzzle.

I also think it's a bit more challenging than a 1-star puzzle. But this novice solver still found it to be loads of fun. Thank you.

Just missed my internal threshold for 1* difficulty (20 min) but as this was my first shifter line puzzle I'm still happy about it

Fun! I was worried I was stuck on a deadly pattern towards the end but I realised what I was missing.
