Only 100 Lines!

(Published on 19. September 2026, 17:33 by thenonymous)

Rules:

Sudoku: Place each of the digits from 1 to 9 once in every row, column, and 3x3 box.

100-lines: Each white segment on a thick grey 100-line contains a number, read either from left to right or top to bottom. The numbers on a 100-line must sum to 100.

Fog: The grid is covered in fog. Placing a correct digit clears fog from that cell and possibly other cells. Guessing is not required.

What an exceptional puzzle, I really loved this one. Please do more. I agree that there was one tough spot.

Mostly a very nice flow, but at one point (you know which) i was stuck for over 30 Minutes. So more like a 2.5* Sudoku for me.
Thanks for this great puzzle!

Has quite a nice solve path, the initial fog lifts helps you to learn how to work with 100 lines, before actually making you think harder later on. Thanks! ;)
