The trick was featured in yesterday's CTC video, suddenly this became a 20 min solve.
Just curious, do you send your puzzles to CTC? I think most your puzzles can match those of their regular favourites.

ND: Thank you very much. No I do not. I thought the recommendations came form other people that enjoy a puzzle.

I believe creators have to submit their own puzzles including an intended solve path. I think they need permission of the creator to use the puzzle. Recommendations can help, I will send them a message as well. Sounds like you can submit 200 puzzles at once now ;-)

ND: Well, they solved one of my puzzles without me writing anything, so I must have been lucky!

Brilliant puzzle! Great use of a hopefully well known trick. Hopefully, because without it the puzzle is really hard I can imagine. Thank you

ND: You are welcome!

Even knowing "the trick" I found it a bit challenging. Love the corner digits!

This puzzle isn’t too difficult if you know the trick, but without the trick, it instantly becomes a much more formidable challenge. So I’m not quite sure how to assign it a fair difficulty rating ;)
Either way, excellent usage of said trick and there is still quite a bit of intrigue to sort through after its deployment. I had fun!

ND: Thanks for the feedback. I agree about the difficulty to estimate it.
