The Odd Road to 200

(Eingestellt am 16. August 2023, 08:00 Uhr von Nordy)

An exploration of the number 200. No calculator or note taking required.


Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.

200-Lines: The digits along each purple line multiply to 200.

The Odd Road to 200

  • Draw a 1-cell wide, non-branching, orthogonally-connected road that does not touch itself orthogonally (but may diagonally). The two ends of the road are given as circles
  • The road contains only odd digits, and the digits along the road sum to 200
  • Except for the circles, the road cannot visit any cell that contains a given clue—the road cannot visit the given digits in R2C9 and R9C1, nor any cell that contains a line segment

I had seen that Simon posted a video with this puzzle. So I wanted to try it myself before watching. Glad I did and kind of proud of myself that I finished it within one hour.
Thanks for posting this puzzle.

This beautiful puzzle is solved by Simon. (Unfortably I don't understand him in this video as a german solver).
Good puzzle!

This was an amazing puzzle! Really satisfying. At the end I added all the odd digits with a calculator and press equal. Seeing that 200 was extremely satisfying. Really enjoyable puzzle.

Amazing construction. The hard part is believing that there's enough information, then it just all flows.

One of the best approachable puzzles that look unbeatable. After you think that is not possible, there is such a nice way with no look back. Proud of myself to finish in 35 Min. ;-)
