Answer String: Enter the 3rd column from top to bottom, followed by a comma, followed by the 5th column from top to bottom. Type both digits of the two-digit numbers 10 and 11. (Note: for the tight fit cells, enter the top before the bottom as would be normal for the read order.)

    I was slowed down by some little mistake while solving.
    It’s interesting to see some tight fit sudoku with another number of digits than 9 ;).

  • Slow, but I was never stuck long, just careful.

    This was a great puzzle. I haven’t played many of these and would love to see more.

    2:45, 5:00, 7:45 for the three tight fits which makes sense based on the master vs expert rating. Will move on to the nurikabe where I expect to be just on the wrong side of the expert fence. Like the new site – even if my work PC doesn’t.

    On these older puzzles, the names given for the time estimates are different than on the newer puzzles, (here we have Master, Expert, and Novice instead of Grandmaster, Master, and Expert on the new ones).

    Are the times for the matching names computed similarly?

    My experience with recent puzzles suggests my solving time for sudoku is generally within 1-2x the expert time, and that does seem consistent here.

      After user feedback over the first five weeks, an adjustment was made to the time standards (see this summary) after prescription 30.
      That post should have it clearer, but originally we did something like top time, 3x top time, 10x top time. This became top time, median of test solvers, 2x median.

      Nothing else has changed in our time standards since that change in early February 2013, although the times were “hidden” by the end of February 2013 unless highlighted.
