    Wow this one was a doozie, one of the toughest puzzles I’ve seen here. After I (finally) found the break in things went fairly smoothly. Well worth the effort!

    It took me 3 days to even think of the break-in. Other puzzles with similar break-in don’t tend to take me that long. I guess it’s just pure unfamiliarity with the type.

    And on top of that, after “solving” the puzzle, I found a thankfully easily-corrected error in my solution.

    Had to play around for a very long time before figuring this one out, extremely frustrating when I couldn’t work it out, but after days of struggling, finally appreciate it’s quite an ingenious puzzle design.

    The other even row/columns puzzles this week didn’t seem too much different from the usual puzzle solve, but this really opens up solving strategies unique to this puzzle variant, quite impressive and really made it worth the effort, thanks!

    You don’t normally expect a minesweeper puzzle to require anything other than very local thinking — very interesting construction.
