All the letters must appear in an вЂњacrossвЂќ word and a вЂњdownвЂќ word. All the words - that is, all the horizontal and vertical sequences of white squares - must be at least three letters long.

They are rotationally symmetric - that is, if you turn the grid upside down it appears exactly the same.Recently, Oliver Roeder of FiveThirtyEight challenged the puzzle fans in his readership to calculate how many different crossword puzzle grids were possible. The creativity of constructors is truly boundless.ДЄnd, it seems, the potential for crossword grids is just as boundless. There is an art to creating an exciting grid, an intriguing theme, or a new puzzle mechanic that solvers have never seen before. They might be able to solve puzzles, but as far as I can tell from my research, thereвЂ™s no program out there capable of generating and executing a theme with any sort of wordplay element involved. When people think of The Los Angeles Times, The New York Times, The Chronicle of Higher Education, The American Values Club, The Crosswords Club, or any of the other well-respected crossword outlets in the market today, I doubt unthemed puzzles are what comes to mind.ДЄnd when it comes to creating themes, innovating, and playing with the conventions of crosswords in order to create puzzles that surprise and challenge solvers, computers simply donвЂ™t have the chops. The answer, as youвЂ™d expect, is simple: computers are just fine at plugging words into established grids and generating basic, unthemed crosswords.

Some companies use computer programs to generate their unthemed crosswords, no human intervention necessary. ThereвЂ™s no denying that computers play a large role in the world of crosswords today.
