Hello, sudoku lovers. I've been doing sudoku for years now. But I usually do them randomly. I try to solve them, and if I don't like something, I change it and try again. But I never thought through the ideas deeply enough so that every detail stood in its place, so that they complemented each other, so that the solution went smoothly and pleasantly. This is my first attempt at doing this. I know I couldn't do it perfectly, but I tried. And I would be glad to hear your feedback in the comments.
