Normal sudoku rules apply.
The lines in the grid are German whispers. Adjacent digits on a German whisper line must differ by at least 5.
Anti-V: No pair of orthogonally adjacent cells in the grid can sum to 5. (To clarify, summing to 10 is okay!)
Have fun, leave a comment if you enjoy the puzzle!

Used the same flawed logic over and over during break-in. Once I realised the mistake, it was a nice solve.

Very nice break-in, surprisingly easy afterwards.
(I do like that zetamath only asks you to enter one row for the solution code.)

Enjoyed this one very much, thanks

Awesome, very memorable design and logic!

Joyful solve - I seemed to instinctively know where I needed to look to progress, which is very rare! Did not make this a simple solve, no siree, but it was really nice to feel like I was following a path for once!

Good puzzle. Loved the break in, and the solve was very smooth. Negative Constraints are always a fun time as well.

I was stuck for the most embarrassingly long time because I forgot about the Anti-V rule. Worse still, it happened more than once!

Once I actually remembered the second rule it became easy! Until then there was a lot of fun head-scratching.

A very nice treat to have an approchable Zetamath puzzle ! Picked it to do a dual solve with my kid :) We both loved it. Thanks.

Very nice construction and deft use of negative constraint. A lot of fun!

Very nice - suspiciously easy for a Zeta puzzle - I kept expecting some sneakery, but it was smooth all the way through :)

I like that the negative constraint doesn't feel overbearing in the solve. Very fun puzzle!

Very enjoyable solve. Realizing what was going on with the break in was a rewarding moment.

It's very good when the negative constraint brings fun instead of pain. Lovely puzzle!
