Silent Snakes (ft. Nordy)
(Eingestellt am 21. Juli 2023, 18:35 Uhr von yttrio)
This puzzle is a collaboration between myself and Nordy, and was inspired by the puzzle Thermosnakes.
Rules:
Normal Sudoku rules apply: Place the digits 1 to 9 in every row, column, and 3x3 box.
Each circle is an endpoint of a nonbranching one-cell-wide snake of orthogonally connected cells, and each circle represents a different snake. No single snake can take up a full 2x2 square within the grid, and different snakes cannot share the same cell. Also, each snake must visit at least two 3x3 boxes within the grid.
The digit in each circle is the length of the corresponding snake (e.g., a 7 in the circle means that the snake must be 7 cells long).
Each snake also acts as a German Whispers line (i.e., adjacent digits along a snake must have a difference of at least 5).
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Note: For 6x6 Sudoku, adjacent digits on a German Whispers line must have a difference of at least 3 (instead of the usual 5)
Play the example 6x6 in f-puzzles.

Lösungscode: Row 8 followed by row 9 (18 digits no spaces)

Beautiful. Unfortunately, in my first try I made a mistake somewhere near the end, that I couldn't dissolve anymore. But the puzzle is so much fun, that I didn't mind starting over again.

That was really nice. I actually used uniqueness to make the final deduction, and thought it was entirely necessary until I remembered one of the special rules that I hadn't used since the start.
