- Normal Rules Apply
- Standard German Whisper
- Standard Killer Cages
- Standard Black and White Dots (No Negative Constraint)
Normal Rules Apply
Place the digits 1 through 9 exactly once in each row, each column, and each 3×3 box.
Standard German Whisper
Digits in cells connected by a green German Whisper line must differ by at least 5. The line itself has no restriction on repeating digits except as implied by the whisper condition and normal Sudoku rules.
Standard Killer Cages
Digits within a cage must sum to the number shown in the corner of the cage. Digits may not repeat within a cage, regardless of whether they share a row, column, or box.
Standard Black and White Dots (No Negative Constraint)
Black Dot:
A black dot between two orthogonally adjacent cells indicates that one digit is
exactly double the other.
White Dot:
A white dot between two orthogonally adjacent cells indicates that the two digits
are consecutive (their difference is exactly 1).
No Negative Constraint:
No negative constraint applies: cells without a dot between them are not restricted
and may still be consecutive or in a 1:2 ratio.
Solution code: Row 1

In terms of some of the deductions you need to make, I agree with others that it feels like a higher 1* or a lower 2*. But if my solve time says anything, it’s definitely a low to middle 1*. I solved it in about 2/3 the time it takes me to solve most 1* puzzles. I think there are some deductions you make from very early on that make the rest of the puzzle a breeze if you are very familiar with GW lines. I can understand if you miss those, it makes the puzzle (and especially the break in) much more difficult.

It was very fun and I agree that the difficulty should be 2*
Thank you for sharing !

Nice one. I would say 2*.

Enjoyable. Break in was probably on the higher ends of 1*. At least for me.

Unless I missed something, this for me is not a 1 star puzzle. Never the less it is a good puzzle.
