Time for a Centennial Celebration!
On December 21, 1913, the first newspaper crossword was published in the New York World. Compiled by Arthur Wynne, the puzzle was called "Word-Cross" and involved 32 across/down clues.
Since then, crosswords have evolved and gotten harder. In turn, they serve as great cognitive stimulants...far better than Sudoko puzzles.
In addition to the geometrical symmetry and visual patterns, I especially enjoy puzzle creator's special clues that mimic math problems to be solved.
Three examples, where numbers in parentheses denote the number of letters in the word(s):
How did you do?
- Gegs (9,4)
- HIJKLMNO (5)
- Scrambled eggs
- Water (i.e. H2O)
