or solve online (using our beta test of Penpa-Edit tools in edgex mode where left click+drag draws lines and right click marks X’s)
Theme: Clue Symmetry and Logic
Author/Opus: This is the 3rd puzzle from guest contributor Bram de Laat.
Rules: Standard Slitherlink rules, except that the edges of the grid wrap around. The top row of dots is the same as the bottom row of dots; the left column of dots is the same as the right column of dots. The loop can now run across an outer edge and continue on the other side. This example image may help:
Answer String: Enter the size of each group of connected squares in the marked rows from left to right; in the example, the bottom row would be “112”.
Time Standards (highlight to view): Grandmaster = 4:20, Master = 6:00, Expert = 12:00
