Tropism
(Published on 4. March 2026, 23:35 by SingingFish)
Hi, this puzzle was set with the break-in in mind which revolves around some ideas I had for interactions between the arrows and the whispers lines. I think the logic is quite nice and hopefully not too hard to find. After that the solve may get a bit tricker but I like the fact that a path can be carved out and a unique solution found with only a few new additional clues. I hope you enjoy :)
Rules:
Normal sudoku rules apply.
Arrows: Digits along an arrow sum to the number in the attached circle.
German whispers: Adjacent digits along a green line have a difference of at least 5.
Solution code: Row 7 (left to right, 9 digits no spaces)

this is almost gas, maybe even gas --> level 1.
all it needs is standard procedures, basic sudoku, and careful scanning.
there are a couple bottlenecks, but just scan well.
hint: where is 6 in box 4 ?

I love the logic that you mention in the description, of the break-in from the whisper-arrow interaction. The whole solve path was fun but that first part was definitely my favorite.
