(Published on 22. November 2025, 12:28 by NurglesGift)

Normal sudoku rules apply.

Orthogonally adjacent cells can not sum to 5 or 10 without a green dot connecting them.

Cells connected by a green dot sum to 5 or 10.

All green dots are given.

Adjacent digits along green lines must differ by 5 or more.

Grey lines are just for visual purpose and do nothing.

Does this puzzle seem to not require negative constraints?
