I'm not sure what's wrong... I'm using the Killer layer every time, and works for me.
I go to Design -> New Grid -> Design and then select each 4x4 cage and press C to set the sum, as simple as that.
I'm using JSudoku 1.5b2 with default preferences.

I can confirm the first one has 1 solution.
Code: Select all
New puzzle
108 nodes traversed
Unique solution found with 6 guesses

About the other two:
Code: Select all
New puzzle Var.1
88451 nodes traversed
Unique solution found with 26 guesses

New puzzle Var.2
2568734 nodes traversed
Unique solution found with 28 guesses

I'm doing just the same!! :cry:

The problem is in fact more fundamental - forget the overlapping cages, it won't let me set any 2x2 cage with sum = 10-11, or 29-30.

And for sum = 12 the pencilmark display shows "1245" only, but should include "36" of course. It's the same for sum = 28, pencilmarks show "9865" but not "74" ...

OK, I fixed it ...

I looked at the registry and found a key which had value "all-non-cons". The penny dropped, you can't make a 2x2 cage with sum 10 or 11 in NC mode!

So I deleted that key and that fixed the problem. Not sure how I got into that state to begin with, but I was fiddling with NC puzzles at some point.

All good now.

Both are unique
for JS the first one uses 27 fishes the second does not solve
