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

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.
