After a few weeks on the injured reserve, Pic-Tac-Toe returns with a mild flourish. As always, 9 images are arranged in a 3x3 grid so that each column, row, and diagonal are linked by a unique theme. With 3 columns, 3 rows, and 2 diagonals, there are 8 themes in all. It's your job to find them.
SOLVED! Thanks to APL (top row), K-Lyn (bottom row, left column, right column), and Bill (middle row, middle column, and both diagonals).
