    About 6:30. I found this one just a steady solve, and felt a little disappointed that there didn’t seem to be big breakthrough deductions or aha moments in a Friday puzzle.

  • Tom Collyer says:

    I have to say I feel a little bad here. I had enough of the puzzle solved to get the answer codes out, without even touching the thematic upper-left 3×3 box. I can only presume that I found a completely separate solving path, which is perhaps testament to how strong the (non) consecutive constraint really is…

      Maybe I should have chosen two rows instead. Towards the end I think you can focus on several places. And the NC constraint is always powerful if you run into it.

  • Ravi says:

    Steady flow for me, only the bottom left box required deduction. The Row A and Column B were revealed even before I could complete 4 3X3 boxes.

    wasted a lot of time fixing the 8 in the 9th box at the start of the puzzle ..i think when i fixed the 8 and saw the timer it was already 8 mins! ..Once i found that it was a bit easier..But a tough puzzle nevertheless…
    Difficulty level on a scale of 10 – close to 8
    Fun level on a scale of 10 – 10!
