Moon-or-Sun 12x12
(Published on 28. April 2025, 15:39 by the_cogito)
Had fun setting this. A bit tricky if you avoid uniqueness deductions :P
Rules:
- Draw a single loop that passes orthogonally through the centers of some cells. The loop never crosses itself, branches off, or goes through the same cell twice.
- A region, bordered by bold lines, is called a "room". The loop goes through each room only one time. Once the loop leaves a room, it cannot return to enter that room.
- In each room, the loop goes through all of the moon cells or all of the sun cells. The loop cannot pass through both moon cells and sun cells in one room.
- After the loop goes through the moons in one room it has to go through all the suns in the next room it enters and vice versa.

Solution code: For every row, the number times the loop traverses horizontally in that row (e.g. horizontal segments of lengths 2, 2, and 5 cells in one row would count as 3 horizontal traversals)

haven't tried without, but with uniqueness deductions it is easy.

Yeah, I know :)
