BWAN 1: Both Window sets and Anti-kNight
I've been working for some time (with Udosuk's help) on generic restrictions to give minimal solution spaces. This is the best that I've found without some form of sequence constraint (LE, GE or anti-consecutive). This puzzle type has 36880 solutions - which can be reduced with symmetry (with sequencing I've got down to one with 36 solutions).
The puzzle: You have two sets of windows which each with hidden windows and hidden stiles. It is also Anti-kNight - cells 2,1 away from each other cannot be the same.
This is solvable without any big vanilla - provided you use the Law of Leftovers fully.
Some of you will know I almost always create killers - but I feel this type works better as a vanilla - and this appears the best place to post it. In addition I need to practice creating these in order to do a vanilla OverKiller.
Ruud - thanks for many hours of frustration with your assassins - I took ages on 84 then tried Gary W's way and it rolled out.
