Also with SiSeSuSo.
Same layout as your Sensei4 orTwin-4 and both Windoku. Note that the entier overlapping part is empty.

Code: Select all: #2/W/B4/E10 .6.........5....3.9...4.5....6................8..........................1....... .......9..........................7................4....7.9...8.6....7.........2.

Only basic techniques needed.

Code: Select all: #2/W/B4/E10 .....2...53....2.1..2.31.....6..................................47............... ...............79..................................3.....48.9..7.8....43...2.....

Basic techniques and Generalized Intersection-methods needed.

Or another idea?

And here the Sohei-1 layout, all Windoku:

Code: Select all: #4/W/H4/B16/N16/H28 1.......6..5...7...6.....3.....6..............1..8..2......................9.4... .9..7.............3........65...2...........648...7...2..................3..8.... ....5..1..................7...2...363...........4...21........3.............1..4. ...2.6......................1..4..2..............8.....9.....4...3...7..4.......8

Symmetrical and only very basic methods needed:

Code: Select all: Eliminated candidates per Method and per Sudoku Method \ Sudoku | SER | 1 2 3 4 |-------|------------------------ Not counted elims | 0 | 186 149 132 132 Naked Singles | 0.1 | 41 30 9 23 Hidden Singles | 0.2 | 66 80 155 125 Naked Pair [2] | 3 | 0 19 0 16 Locked Singles[2] | 2.8 | 23 25 19 13 |-------|------------------------ Eliminated Cand's | 1243 | 316 303 315 309 Sum(SER * Cand's) | 424.5 | 81.7 146 85.1 111.7 Initial Candidates : 1243 Maximum SER rating : 3 - Approach Labour rating : 424.5 - Experimental rating

Or this sohei-1 layout:

singles only

Or thisone which needs a few skyscrapers:

Example which needs some fish(x-wing/swordfish/jellyfish):

Code: Select all: #4//H4,JS/B16,JS/N16,JS/H28,JS 9.7...8.2............9.4...85..6..13..8...7...3.....8.............6.3............ 112334444122344444112355666122357776112357676122357666888357999888357999888557999 1...74.....................4.59..............2.48.......................8...19... 111111222113331222444433222445453666775453336875456666875556999877777999888888999 ...76...2.......................97.5..............16.7.....................93...8 999888888999777778999655578666654578633354577666354544222334444222133311222111111 ............3.7.............6.....3...5...6..49..2..15...7.6............5.3...2.7 999755888999753888999753888666753221676753211677753221666553211444443221444433211

Tried my sohei solution generator:

And a very-hard example:
