Mïnigandr
(Published yesterday, 01:20 by berdy)
This puzzle is inspired by one of the first puzzles that got me into this hobby, and one of my favorites to this day — Jay Dyer’s Jörmungandr!
Rules
Regions
Divide the grid into four orthogonally connected regions of nine cells each.
Each region contains the digits 1-9 once each.
Digits do not repeat in any row or column.
Snake
The blue-orange line is a region sum entropic line.
Region sum: Every segment of the line that passes through a region has the same sum. Multiple passes through the same region are calculated separately.
Entropic: In the direction of the pointed bands (e.g. r1c1 → r2c2) digits cycle high (7-9) → medium (4-6) → low (1-3) → high. The line may start with any digit.
Solution code: Digits in the region containing r6c6 (reading order)
