Orange & Blue Fog
(Published on 14. January 2025, 12:13 by FJL)
Normal sudoku rules apply.
Digits along an arrow sum to the digit in the arrow circle.
Digits separated by an X sum to 10. Digits separated by a V sum to 5.
Adjacent digits along a green line differ by at least 5.
Digits marked by a grey square are even.
Entering a correct digit will reveal the cells around that digit (clear the fog).
In addition: no row or column can contain a consecutive sequence of 3 or more digits of the same polarity (odd/even).
Solution code: Row 5

Gorgeous puzzle with a clever break-in and a quite hard to spot sudoku step near the end, at least it took me a while! Thank you

R5C1 truly hides all the magic. Incredible

Hint for the start: is the parity of R5C1 restricted and why would it matter?

The break-in is hard to see but definitely doable! Good puzzle

Wonderful puzzle - surprised by the current low rating. The break in is tough but fair and there are plenty more tricks as the solve progresses.

Same here.

Unfortunately I fail to notice the starting point. With initial guess, puzzle is doable, but I just cannot disambiguate the beggining. If someone can share the approach I would be grateful.
