    (But even then, I botched connectivity placing the final piece, which I didn’t realize until the website correctly refused to accept my bogus answer.)

    23:23.Great design!I was so wrong in assuming that the puzzle would be easy after seeing so many 4 cell regions.The puzzle turned out to be increasingly sticky with some narrow deductions in the middle and towards the end.
