Here 2 examples found with a SE 4.2 rating, so human solvable? I doubt because they have a lot of generalized intersections.

And the same 4 Jigsaw-pieces, but no diagonals. SE about 6.3

Code: Select all

#1//B4,JSB
3..4..2...........4......8.7...1....6...9...3....2...6.8......1...........2..6..7

And this is a same layout, but with Ferz-Non-Consecutive constraint (diagonal adjacent cells are not consecutive) and point symmetric.
It starts with only 8 givens.

Code: Select all

#1/FNC/B4,JSB
.7.....86................2.............................3................25.....3.
..........111..333.1.1133.3.11....33.21...43.22....44.2.2244.4.222..444..........


and only Naked/Hidden Pairs (no Triples or Quads) and Pointing/Claiming is needed.
