Absolute Zero
(Published on 8. March 2024, 08:24 by juggler)
Place the digits -4 through 4 in the grid so that each digit appears exactly once in every row, column and 3x3 box. The minus sign is omitted when writing negative digits into the grid (e.g. both 2 and -2 are written '2').
Digits along an arrow sum to the digit in its circle.
Digits with a white dot between them are consecutive.
Solution code: Row 1

Interesting, the thinking is so much smoother once I realize the positive or negative of one particular digit doesn’t really matter at all. This is such a tricky design

What a beautiful puzzle, with a refreshingly novel ruleset! I am glad to have picked this for my 600th solve here. Thanks for setting and sharing, @ juggler :).

I found this very challenging, but well worth it. Really fun solve as it all came together.

Very funny box 7 :)
Edit: As with efnenu, I ended up with row 9 filled out relatively early on.
