Samurai Windoku X Killer 1

I've seen Samurai Windoku before but I noticed that the structure was wrong. This is the correct way to lay them out. Note all five sub-puzzles are windoku and the linkages mean a window in the centre is a nonet in the corner and vice-versa.

Not too hard, serious use of LOL but no fishes. I expect Matt to do it on paper with markings.

I will do vanilla and Supea versions later.

Nice idea HATMAN,

I myself favour a Vanilla central subgrid .... With satellite Subgrids being Windokus.

That is my view for Gattai-5 anyway

What puzzles me is your choice of two extra cages in the Bottom Left grid to establish uniqueness, when you only need one elsewhere (e.g. 9/2 @ r3c45 in the Central grid). Ideally the whole setup should be perfectly symmetrical but unfortunately it's not likely to be possible.

I take your point, but this way the puzzle is more "restrained".

Matt

I did get a bit obsessed with the bottom left grid, and was happy enought to find diagonal symmetry.

I'd like to see a standardized method for specifying the additional houses in a sudoku variant, akin to the puzzle specification, such as

..........6....2..9..8.7..4.3..2.........1.7........98....6......1......7.8....1.

to specfy



I would propose something akin to that notation, say
1.......2.1.....2...1...2.....1.2.......3.......2.1.....2...1...2.....1.2.......1

which specifies

for the sudoku-X. We still need to specify that the main diagnol is both cells marked 1 and 3 and the main anti-diagnol is cells marked 2 and 3.

another, example, a simple "Windoku" can be given as:
..........111.222..111.222..111.222...........333.444..333.444..333.444..........

which maps out as
