We all go a little mad sometimes, and I found myself supremely frustrated trying to finish this one. So I enlisted the help of K-Lyn, who pushed this puzzle through many incarnations, allowing me to stop thinking about it for a while and then actually be productive, finishing it when the time was right. Really, this could just as easily been over at her blog. But it's my addled brain on display, so my 10th Pic-Tac-Toe (two whole feet!) is here instead.
Below are 9 images arranged in a 3x3 format. A unique theme connects the images of each row, column, and diagonal. That's a total of 8 themes. Solve the puzzle and I'll try to do it all over again. As K-Lyn will attest, that order's getting taller and taller.
Obviously, K-Lyn is ineligible, so my thanks will have to do.
SOLVED! Bill did quite well on his own, perhaps even improving my left column. Don't know if I'll come up with an 11th puzzle in a week; the process is exhausting, even with the gracious help/control of another.
