Erica 31

I am happy to present another easy Erica, it has only one minimally tricky point in the break-in, but I believe it is still 1*, maybe 1.5* :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

German whisper: Adjacent digits along a green line have a difference of at least 5.

V: Digits in cells joined by a V sum to 5. Not all Vs are given.

My solve time makes me vote for 1.5-2*. Maybe this is one of my slower days. Great puzzle however. One easy to miss step.

Nice puzzle! Agree it's a 1 star, but I'd say it does require a bit of experience with german whispers to get the break in.

Got the break in rather quickly but bogged down in the middle finding what looking back now seems should have been obvious to me. Fun puzzle.

Lovely! The break-in was a touch more involved, and then the rest of the puzzle felt *1 to me. I enjoyed using the symmetry :)

Very approachable and fun. Not quite a speed run for me, 20 minutes over a cup of coffee.
