Dr. Sudoku Prescribes #100 – Masyu
or solve online (using our beta test of Penpa-Edit tools in linex mode where left click+drag draws lines and right click marks X’s)
Theme: Half and Half
Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. If the loop only has vertical segments in the marked row, enter 0. Separate each row’s entry with a comma.
Time Standards (highlight to view): Grandmaster = 2:00, Master = 3:30, Expert = 7:00
Editorial Note: As we celebrate the milestone of our 100th puzzle, there are two other milestones coming this week. First, the US Sudoku Qualifying Test contains many of our puzzles; best of luck and skill to the competitors. And later this weekend we’ll have a very different kind of contest here. Watch out for it.
