Foggy Contours - Region Sums
(Published on 6. October 2025, 01:29 by pagedo)
Normal Sudoku Rules apply.
Box borders divide a blue Region Sum line into segments with the same sum. Different lines may have different sums.
Cells joined by an X sum to 10. Cells joined by a V sum to 5.
Cells joined by a white dot are consecutive. Cells joined by a black dot, one digit is double the other.
Not all Xs, Vs or dots are given.
Parts of the grid are covered in fog. Placing correct digits may clear fog somewhere in the grid.

End felt kinda weird. I like having to deduce numbers in the fog, but it lasted so long...

Love the way the fog keeps you guessing here.

Very nice puzzle. The dynamic fog was a bit confusing as it didn’t always reveal correctly entered cells which was a bit disconcerting. Got there in the end though - very nice puzzle, thank you.

Oo that tested my confidence in my decisions, certainly! The relief when the fog did indeed clear.

Took me way to long that the letter in col 5 is a V not a X

I love how it doesn't give you an immediate feedback and some cells are still covered in fog even when the digit is right, you have to trust your deductions until the next reveal. Beautiful!
