I did the same, then made a "leap of faith" for C9 and C12, and lucked out with that guess.

Very nice Brian. Great title too.

Bruce. I like your leap of faith idea. I always solve my own puzzles and pretend I don't know the solution. In this puzzle I place a lot of pixels in the wrong places along the top row until I found the ones that didn't lead to a contradiction. Since it was so difficult, I gave it that title.

yeah, Emily..you can assume symmetry. But it takes 5 mins to solve once you do. I was trying the hard way...

Easier way to look at it once you do. any single clue has to straddle the middle, ie you can place the 2 in r20 straight-away. If there's an odd # of clues in a symmetrical puzz, then the middle clue straddles the mid-axis. From there, i'll let you make your own assumption on even # clues in a row. Once you know it's symmetrical, there are a whole host of constants you can draw upon. You're right though. Once you have an axis, you're basically splitting up the puzz into halves or sections. You do enough of em, you can visualize what the image looks like with a glance at the grid...before you even begin to solve. I did a cursory glance and knew there was a v-shape coming up from the middle and thought, "it's not quite a heart, but the bottom 3/4 has a heart-shape. It's not pointed at the top portion like one though, more rounded".

I was just doing a diff puzz of Brian's earlier today that dealt with amplitudes and wave-lengths. Somehow it got marked as "much-guessing", but it was completely logical, and almost color/line solvable. But it was broken into sections, or shoulda been. No guessing, and nothing even difficult. It was a well-made puzz.... (I hate when ppl rate as guessing just cuz they can't figure it or missed something. If you don't know, don't rate)

Good image, and small enough to make for an interesting go at it! Thanks for the puzz, Brian! I'm def getting my money's worth out of it :)

I like this image—did not see it when I had half.
