20x20 Feeling Squared [The largest empty suguru in the world...]
(Eingestellt am 30. August 2025, 14:44 Uhr von Jacoba)
A gigantic suguru with no given clues (with high complexity).
Rules: 1. Each region must contain all the digits 1 to the size of the region.
2. No same digit appears in any neighboring cell, not even diagonally.
The largest empty suguru in the world until now (as far as I could find) was the 9x9 from Kris van Dael on Math.Stackexchange

The beginning was definitely easier than the end. Great Suguru. :)

Seems that I'm the first solver! I didn't think it worth a four-star rating until I solved about 2/3 of the grid.
