Most puzzle designs also require that all white cells be orthogonally contiguous (that is, connected in one mass through shared sides, to form a single polyomino).Some clue examples: The constraints of the American-style grid (in which every letter is checked) often require a fair number of answers not to be dictionary words.As an example, the New York Times crossword of April 26, 2005 by Sarah Keller, edited by Will Shortz, featured five themed entries ending in the different parts of a tree: SQUARE ROOT, TABLE LEAF, WARDROBE TRUNK, BRAIN STEM, and BANK BRANCH.Many puzzles feature clues involving wordplay which are to be taken metaphorically or in some sense other than their literal meaning, requiring some form of lateral thinking.For instance, the puzzle Eight Isn't Enough by Matt Gaffney gives the clue "This week's contest answer is a three-word phrase whose second word is 'or'."[15] The crossword solution includes the entries "BROUGHT TO NAUGHT", "MIGHT MAKES RIGHT", "CAUGHT A STRAIGHT", and "HEIGHT AND WEIGHT", which are all three-word phrases with two words ending in -ght.[19] The daily New York Times puzzle for November 5, 1996, by Jeremiah Farrell, had a clue for 39 across that read "Lead story in tomorrow's newspaper, with 43 Across (!).[21] On September 1, 2016, the daily New York Times puzzle by Ben Tausig had four squares which led to correct answers reading both across and down if solvers entered either "M" or "F".For example, in one puzzle by Mel Taub, the answer IMPORTANT is given the clue "To bring worker into the country may prove significant".Other words relating to sound or hearing can be used to signal the presence of a homophone clue (e.g., "aloud", "audibly", "in conversation", etc.).Colin Dexter advised that "Usually the indicator will be an adjective (drunk, fancy, unusual, and so on); an adverb (badly, excitedly, unexpectedly); a past participle (altered, broken, jumbled) or indeed any phrase giving a similar meaning.Published under various trade names (including Code Breakers, Code Crackers, and Kaidoku), and not to be confused with cryptic crosswords (ciphertext puzzles are commonly known as cryptograms), a cipher crossword replaces the clues for each entry with clues for each white cell of the grid—an integer from 1 to 26 inclusive is printed in the corner of each.As these puzzles are closer to codes than quizzes, they require a different skillset; many basic cryptographic techniques, such as determining likely vowels, are key to solving these.These types of crosswords are also used to demonstrate artificial intelligence abilities, such as finding solutions to the puzzle based on a set of determined constraints.The second part is a long series of numbered blanks and spaces, representing a quotation or other text, into which the answers for the clues fit.[33][34][35] Crossword puzzles became a regular weekly feature in the New York World, and spread to other newspapers; the Pittsburgh Press, for example, was publishing them at least as early as 1916[36] and The Boston Globe by 1917.In October 1922, newspapers published a comic strip by Clare Briggs entitled "Movie of a Man Doing the Cross-Word Puzzle", with an enthusiast muttering "87 across 'Northern Sea Bird'!!??!?!!?Edward Powys Mathers set the first crossword to use entirely cryptic clues, originally just for the enjoyment of his friends, one of whom, without permission, submitted it to the Saturday Westminster Gazette.Derrick Somerset Macnutt, who took over at Mather's death, chose the pen name "Ximenes," an Anglicization of the surname of Francisco Jiménez de Cisneros, a Grand Inquisitor in Castile.The current Observer cryptic compiler, Jonathan Crowther sets under the name "Azed," a reversal of Deza, another Grand Inquisitor.From 1977 to 2006, The Atlantic regularly featured a cryptic crossword "Puzzler" by the husband and wife team of Emily Cox and Henry Rathvon.In the United Kingdom, the Sunday Express was the first newspaper to publish a crossword on November 2, 1924, a Wynne puzzle adapted for the UK.The design of Japanese crossword grids often follows two additional rules: that shaded cells may not share a side (i.e. they may not be orthogonally contiguous) and that the corner squares must be white.Swedish crosswords are mainly in the illustrated (photos or drawings), in-line clue style typical of the "Swedish-style grid".These puzzles usually have no symmetry in the grid but instead often have a common theme (literature, music, nature, geography, events of a special year, etc.)Both major evening dailies (Aftonbladet and Expressen) publish a weekly crossword supplement, named Kryss & Quiz and Korsord[85] respectively.[95] The compensation structure of crosswords generally entails authors selling all rights to their puzzles upon publication, and as a result receiving no royalties from republication of their work in books or other forms.[97] The earliest software relied on people to input a list of fill words and clues, and automatically maps the answers onto a suitable grid.Modern open source libraries exist that attempt to efficiently generate legal arrangements from a given set of answers.[98] In the late 1990s, the transition began from mostly hand-created arrangements to computer-assisted, which creators generally say has allowed authors to produce more interesting and creative puzzles, reducing crosswordese.
