Since my VH puzzles are only being viewed w/o any replies, it doesn't make sense to post a thread for each puzzle. From now on, I will simple add new VH puzzles to this thread.

Replies is a hint. Number of views is important too.

Give it some thought. Question

For NNP #4, I used five steps but I believe one or even two were unnecessary to solve the puzzle. My biggest problem was a missed basic step.

Hint:
Quote:
x-wing4, UR78 with strong link <8>, diagonal UR13 with strong link <1>, xy-wing257 with pivot <25> and a BUG+1.
It was a missed quad that caused me some pain!

For NNP #28, I found numerous steps, but a simple VH three-step solution is available. I suspect someone will find a one-stepper.

Hint:
Quote:
x-wing4, and two Type 1 URs: UR 28 and UR18

For NNP 4, I used an XY-Wing on 257 which led to a BUG+!.

Danny, I really like your puzzles, but I can't for the life of me understand why you want to put multiple puzzles in one thread, regardless of number of replies generated. Question Question Question
