Oops. The 9 is misplaced. Corrected and indeed no solution found with logic and not even with Nested Forcing Nets .

corrected typo:

Code: Select all: #9/X/B4/N4/H16/B28/N28/H4/B16/N16/H28 ..9......................9....................................................... .....................7...6................................9..7........9.......... ...........................................................................8..... ...................................88...........6....................3........... ....6....................8..7.........1....3..3..17...............72...6......2.. ...2...............9............5.......3........4............................... ................................................................................. ....9..7........9.......................1.......5...2.....6....................8. .....................8.......8....7.........1.......3..........3.................

1. SingleOnly

so i should use this to practice "singles"

but so many box-line interactions
just jump to my eyes
(while i miss some "singles")

In another puzzle I was glad to get a solution path.
Here is a possible solution path for the #1 puzzle (singles only)

9 Overlapping Sudokus, all with diagonals too. All overlapping boxes are clueless.

I wondered whether it's possible to remove all the clues on all the many diagonals as well as those in the overlapping regions. With a new solution grid that I genereated I almost reached the goal, except for one pesky clue in subpuzzle 1 (1r7c2), which sits on a UA4. An example is:

Code: Select all: . . . . . . . . . . . . . . . 5 . . 4 . . . . . . . . . . . . . . . . . 8 6 . . . 3 . . . . . 9 . . . . . . . . . . 4 7 . 6 . . . 2 . . . . . . . . . . . . . 8 . . . 9 4 . . . . . . . . . . 1 . . . 1 . . 7 . 6 1 . . . . . . . . . . . . . . . 3 . . . . . 1*. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 . . . . . . . . . . . . . . 3 . . . 7 . . . . . . . . . . . . . . . . . 5 . 6 . 7 . 1 . . . . . . . . . . . . . . . . 8 3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 . 5 . . . . . . . . . . . . . . 4 . . . 6 . . . . . . 7 . 3 . . . 4 . . 1 . . . . . . . . . . . . . . . . . . 9 . . . . . 4 . . 8 . . . . 4 . . . . . 3 . 6 . 2 . . . 9 . . 4 . . . . 8 . . . . 2 . 5 . . . . 3 . . 9 6 . . . . . . . . . . 8 . 5 1 . 55 clues, all overlapping regions and diagonals empty (except r7c2, see asterisk)

Another example is in the file attached.

I tried it with hajime's grid too, without success, and I think I'll stop there.

Same question: can you provide the grid in 9 X 81 strings?
Same promise: tomorrow I will try to solve it
And also to find a puzzle with all overlapping areas and diagonals without givens

I must have made a mistake. It works with that grid:

Hmmm, creating a W-SamuraiPlus (with windoku's in stead of diagonals) seems difficult....

Think I'll give that a miss!

I could not find a W-SamuraiPlus, but a symmetrical A-SamuraiPlus (with Asterisk) is here :geek:

Overlapping boxes and all asterisks are clueless; clueless middle area of 13x13.
A solution is possible with Naked/Hidden-Pairs/Triples and Pointing/Claiming

In code: Show

I will not pursuit anymore ...
