Before they became perfectly symmetrical squares, word puzzles were wild experiments in geometric chaos. Arthur Wynne published the world's first 'Word-Cross' in the New York World newspaper in 1913. Instead of the tight grid we know today, he arranged the blanks into a massive, hollow diamond shape with no black squares whatsoever. It looked less like a casual brain teaser and more like a demonic summoning circle printed in ink.
