Deconstructed 4x4s are not fun
(Published on 24. April 2025, 11:00 by graggle)
- Fill the grid with 4 non-overlapping 2x2 square regions, such that each region contains the digits 1-4 once each and no digit repeats in any row or column. Cells outside regions do not contain digits.
- All cells that contain digits must be orthogonally connected.
- Anti-king: Cells separated by a kings move in chess cannot contain the same digits.
- Region sum lines: Region borders divide each blue line into segments with the same sum. Segments of the line that are outside regions are ignored.
Solve it on CTC .
Solution code: Row 1 followed by row 2, left to right. Use dashes for empty cells. Answer should be 10 characters, no spaces. (e.g. 123-434-21)

This puzzle is quite the novelty! Though I agree with the title that it wasn't much fun to solve, since I had to resort to some trial and error. Maybe other solvers found a more clever approach?
