From the Foxger’s Den #46: Masyu (All Cells)
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)
This is a “Twisted Tuesday” puzzle variation.
Theme: All Cells and All Antisymmetry!
Rules: Standard Masyu rules. Also, ALL CELLS must be visited by the loop.
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 = 1:45, Master = 2:30, Expert = 5:00
Solution: PDF
Very nice. Reminds me of some of those Nikoli puzzles where they use 98% of the grid, but somehow can’t fill the last 2 percent in. Those always leaves me with a bit of unsatisfactory feeling.
2:21. Having “Simple Loop” rules meant there were more tools in my belt for this one, so it felt like there was always a place somewhere to make quick progress. Classic Simple Loop staircasing at the end. I feel that’s a term I just invented, but I bet people will know what I mean without further explanation.
Hope to see some of these variations in your upcoming book as well. Will/would make the book seem a bit more exciting compared to things like “The monster book of puzzles” by Nikoli.
02:28. MS Paint is baaaaad.
Nice one. When I saw a redundant clue in bottom-right, I immediately inspected its top-left counterpart; that’s the thing that made me to realize this is antisymmetric. Neat aesthetic theme, and the path is pretty straightforward which means good enough for Tuesday.
