Because you stated that your puzzles can be solved manually, I stated that too. But it is not true.

And I have no solving method that comes even close.

Looks impossible to me. I am curious about the solution logging.

So the Star Wars force was not with me, and I went to Star Trek's Kirk method: I cheated.

hmmm ... As I post for other players a variety of puzzles from sudoku to variants and more over 15 years, I'm usually careful at making statements about how a puzzle is rated ... It would always be helpful to have a freely available solver that could demonstrate this like

Sukaku Explainer which rates both of my puzzles at 3.2 which means "X-Wing" to solve (The Hint being may the force be with you in reference to Star Wars ... I've used this hint countless of times before "My Girandola puzzle thread being one of them"). The solving path is tedious but this is what you get with an AK AN FNC puzzle!!!

I post also puzzles targeting machine solvers as well & I also try to make sure that this is clear in the description. Rating puzzles is by far the most difficult in puzzle creation.

We have discussed a few non consecutive techniques before here:

http://forum.enjoysudoku.com/post285907.html?hilit=locked%20non%20consecutive#p285907The middle section of your Samurai is a standalone single solution puzzle which is verified by Sukaku explainer's brute force solver. With the other grids not having any clues you will need to have some information coming from that central grid so that the other grids can reduce the difficulty of solving the puzzle. Unfortunately, little information is available even after reaching SE difficulty levels of 9.0+ which basically puts it out of being a manual solving puzzle at this level. Try feeding the central grid only into Sukaku Explainer to see how far it gets. That is why I asked you about techniques just in case I was missing something!
