Ordered NC Vanilla 1
I always find that NC is too restrained and CNC even more so, hence when trying to make a killer the cages end up too large. They also cause what I call the cliff-edge problem: add a clue to make the puzzle solvable and then it is too easy. This is particularly the case with MeanDoku.
I therefore thought to reduce the restraint by requiring NC in one direction only. I have gone for rejecting increasing as they are slightly more obvious visually. Due to reduced interactions the restraint level is reduced by more than 50%, I would guess to about one third.
Ordered (orthogonal) NC: horizontally and vertical increasing consecutive numbers are not allowed so 9-8 is OK but 8-9 is not.
tarek has kindly provided me with a set of solutions so here is the first one.
Probably medium difficulty once you are used to it, as it took me a few tries to do it without fishes.
