Find someone who looks at you the way Simon looks at a truly brilliant sudoku

First deduction of the puzzle: no threes in the corners, because the corners are covered with 21 cages 😧

If you had told me four hours ago that somewhere out there there was a 5-star difficulty pure killer, with new and innovative logic I hadn't seen before, I'd have laughed and told you that pure killer (while fun) was really played out. Bonkers, absolutely bonkers.

"Let's look at 7s..." for 0.2 seconds. "Let's look at 8s and 9s instead." Classic Simon.

Impressive solve from Simon once more, I tried for a little but I quickly understood that I would never solve that one and went straight to watch the video

This managed to take me over 4 hours to complete, even with <b>extensive</b> use of the check feature. Looking forward to watching the video and seeing all the obvious deductions/logic that I completely failed to recognize😅

This is one of those puzzles where I need Simon to create a bow wave of reasoning that I'll happily surf along on, trying my best to stay just ahead of the crest of Simon's deductions, by hopefully reaching the deductions for myself first. <br><br>Sometimes, I'll surf far ahead of Simon, before becoming becalmed in a sea of confusing possibilities. Then I'll wait for Simon to catch up. Just occasionally, like today, I'll catch a ripple of inspiration while I'm waiting, and be off again before Simon reaches me. 🙂
