Authorized by the author 红葉（MOMIJI), he plans to publish his hand-made standard puzzles on this website, with 1 to 2 questions per week. If you like it and have good suggestions, you can leave a message.
1. Make a single loop with lines passing through the centers of cells, horizontally or vertically. The loop never crosses itself, branches off, or goes through the same cell twice.
2. Lines must pass through all cells with black and white circles.
3. Lines passing through white circles must pass straight through its cell, and make a right-angled turn in at least one of the cells next to the white circle.
4. Lines passing through black circles must make a right-angled turn in its cell, then it must go straight through the next cell (till the middle of the second cell) on both sides.
Author: 红葉 (MOMIJI), from China, this question comes from his personal blog.
Lösungscode: For every Row from top to bottom, enter the number of cells in which the loop turns.

I think it is worth putting the rules of Masyu in the puzzle description.
