X---V*5

(Published on 25. April 2025, 06:00 by NurglesGift)

Normal sudoku rules apply.

Orthogonally adjacent cells can not sum to 5 or 10.

Two lines of the same length and same color are connected X lines.

Counting from the bulb, the first cell of each connected X line sum to 10. the second cell of each line sum to 10 etc.

There is a 3x3 magic square somewhere in the grid.

(A magic square is a 3x3 square with the digits 1-9 where all rows, columns and diagonals have the same sum)

.............................

Note that 5 can be on a line.

I thought it deserved 5 stars

I put this one as 4* and I think that is fair.
Sure after the break in you could argue it's no more then 3*. but then again even if the logic is not extreme I'm sure many people spend hours on the solve. and then should a puzzle rating be for people who done other puzzles of this kind or for completely new people? :)

I don't normally comment to say a difficulty rating is wrong (though I have given my personal thoughts on difficulty) because ultimately what is easy/hard for one person can be totally different for another. So a crowd made difficulty will be fine. But I have to say this one seems way off. If you have any familiarity with this ruleset and magic squares (which I think is most of the community) this is pretty routine and is more a 2.5* puzzle, imo. Unless I really screwed up logic somewhere but got lucky this is no where close to 5*

I had to resort to some light bifurcation just at the start, after that flowed very nicely.
