1, 2, 3 crossword

A crossword variant in which 1, 2, or 3 letters may be written into each square. There are variations of this variant, which may allow different numbers of letters in the squares (such as the jumping crossword where 0 or 1 letters are allowed), and double-or-nothing, which allows 0 or 2. When only a few squares contain multiple letters and the entries in those squares are related somehow, it is instead a rebus crossword.

Akari (Light Up) puzzle

The standard form of this puzzle consists of a grid where some cells are initially blacked in, and some of those contain numbers. To solve it, place lights (which illuminate all squares in a horizontal or vertical line from the light to the next black square or the edge of the puzzle) in some cells so that every square is illuminated by at least one light, no light is illuminated by another light, and the number of lights orthogonally adjacent to each number matches the number.

alphablock

The standard form of this puzzle consists of a square grid with a letter or group of letters in each cell. To solve it, spell words, phrases, or names reading left to right across the grid by taking one cell from each column. Each cell is used once. The items formed are members of some set or category, except for one answer which identifies the category.

Alphacipher

The standard form of this puzzle type is a list of words, along with their values in a cipher which applies a different value from 1 to 26 to each letter of the alphabet, and adds up the values of the letters in each word. It's similar to an alphametic but there's no interaction of place value, and usually the whole alphabet is used.

MIT Mystery Hunt 1994 22

alphagram

In the standard version of this puzzle type (also called Alphabet Soup in Penny Press magazines), there is a grid which has 26 rows and an odd number of columns (typically 11 or 13) and all the cells except the center column are pre-filled with letters. The solver must fill the letters A through Z into the empty cells so that each row contains a word of some minimum length in a group of consecutive letters.

alphametics (encoded arithmetic)

These puzzles are essentially solved arithmetic problems (often long division or multiplication with all the partial products written out), with the entire problem encoded into letters with a simple substitution cipher. Sometimes the key (what 0123456789 encodes into) spells a final answer. A variant sometimes seen uses stars or blanks to indicate unknown digits.

Alpha Sleuth

This puzzle type consists of a criss-cross-style grid with some letters pre-filled. There are exactly 26 unfilled spaces which need to be filled in using every letter of the alphabet once, forming words that have something in common. Some unfilled spaces have a number. A set of numbered spaces (possibly with repeats) below the grid uses the letters in the numbered grid spaces as a key, producing a final answer word or phrase.

Alternate Corners puzzle

In this puzzle, you must draw a closed loop through every cell in a grid going only in orthogonal directions. Some cells are marked with a circle and the path must always turn in these cells. The path always turns exactly once between two circles.

balance puzzle

The standard form of this puzzle includes a set of two or more hanging beams marked off in equally spaced intervals, with weights and/or other beams hanging at some of the marked points. This structure, a bit like a mobile, is meant to balance by the torque rule - for each beam, the sum of (weight x distance to fulcrum) for all weights on one side of the fulcrum equals that sum for the other side, the fulcrum in this case being the point the beam hangs from. The beams themselves are weightless but convey the total weight of the weights they hold to the beam they hang from. The values of the weights must be filled in from a predetermined set, usually 1 to N where N is the number of weights.

Bananagrams

Bananagrams is one of many fast-paced word-building games which all use the following general rules:

Each player draws some set number of tiles from a large supply at the start of the game.
At a signal, all players flip over their tiles and try to arrange them all into a legal Scrabble board. All letters must be used to form words, all the words must interlock into a single network, and all groups of adjacent tiles must form words reading left to right or top to bottom.
The first person who succeeds in doing this calls out some signal (like "Draw!") at which point each players draws two (or only one, in some games) more tiles from the supply.
All players rebuild their layouts to incorporate the new letters. You can rearrange the letters arbitrarily, but you are going to be faster if you can just add the tiles as a new word or extend an existing word.
The first player done calls out and more tiles are drawn.
Repeat until there are not enough tiles remaining for everybody to draw new tiles.

The bifid cipher is a cipher based on taking indexes into a 5x5 square of letters, but instead of turning the text into numbers, the numbers are read in a different order and converted back to letters through the square. The link explains in more detail.

binary/biliteral/Baconian cipher

This includes any 5-bit binary for letters in alphabetical order. The binary cipher usually goes from 00001 for A up to 11010 for Z. The Baconian cipher, named for Sir Francis Bacon, usually started at 00000 for A, and classically (because of old Latin rules) combined I and J as one letter and likewise for U and V. Modern implementations often ignore the IJ/UV pairing and just work as an off-by-one version of the binary cipher. Finally, either of these may be presented as a biliteral cipher, which means the binary is hidden as two variations of items within a cover text of some sort. It's up to you to figure out which variation is 0 and which is 1, but usually not hard to determine.

book cipher

In the book cipher, a series of numbers are given which index into a known text to extract letters or words. The exact indexing mechanism varies, but it could involve pages, lines, words, and letters if the text has known pagination, or chapters/sections, words, and letters if the pagination is not known or consistent, or simply words and letters if the document is short.

book code

A type of cipher where a book or other widely available text is used as a key, and the message is encoded as a series of numbers which are indexes into the text. Indexes may be single (word or letter counts in the entire text) or multiple (indexing first by page, then by word, or first by word, then by letter, etc.) This is sometimes called a Beale cipher, in reference to a famous one which used the U.S. Declaration of Independence as a key.

Braille

This includes all forms of Braille. Some puzzles use only the common 26 symbols representing the alphabet. Others may use symbols representing punctuation, word parts, and sometimes whole words; this level-2 Braille is context-dependent and so generally requires knowing the word breaks and adjacent characters to interpret properly.

cartoon rebuses

Cartoon rebuses are a type of puzzle made popular during the contest craze of the early 20th century and revived in Games Magazine. A single black and white comic-style scene conceals a name or phrase by breaking it up into parts which combine, phonetically, as in a rebus (but without subtraction) to form the answer phrase. Each part is depicted in the cartoon, possibly as a word in a dialogue, a letter on a shirt, a pictured object, or something strongly implied by the scene. These parts are hidden among other irrelevant bits to make a comic scene. A category and the enumeration of the letters in each word of the answer is given.

city address grids

Some cities, or parts of cities, have a rectangular grid of streets, with the street names in one or both directions being sequential numbers or letters, and often with the addresses matching cross-streets (so the addresses on a street between the intersections with 5th and 6th streets would be between 500 and 600). Although the distance between each pair of streets is not always the same, this provides opportunities to interpret the map as a Cartesian plane.

crossword puzzles

The standard American-style crossword puzzle, occasionally with a more open-form grid than usual. See crossword variants for those where words are entered in unusual ways, and cryptic crosswords for puzzles with cryptic or British-style cluing.

Modern crossword puzzles sometimes include one of a number of tricks, and naturally these show up in hunts as well. Among these are the rebus crossword in which more than one letter is written into a few squares of the crossword, and deletion or letter change themes in which the theme entries are modified in some way to fit into the grid.

cryptic crosswords

This category includes cryptic double-crostics and the like, but see cryptic crossword clues for puzzles where the clues stand alone and their answers do not go into some sort of grid. American cryptics are defined rigidly by a set of rules from British setter Ximenes, presented to American audiences by Stephen Sondheim in 1968, while British ones are often looser in applying these rules.

There are two standard versions of this puzzle. In one, you're given one starting word in a big open grid, and you are given not only the word list but also the list of words that cross each word, in order. In the other, you're given the word list, and the grid is pre-filled with all occurrences of one or more letters which are frequent in the word list (sometimes rebus-style, with a word of two or more letters written into the pre-filled cells, though the other squares are normal).

In the standard form of this puzzle, clue answers are written on a set of numbered blanks, then transferred into a grid where words (usually spelling a quotation) read only across, wrapping around the ends of rows. Normally, each number appears only once among the answers and the grid contains the letter of the clue which uses that number, so that you can also work from the grid back to the clues. The initial letters of the answers, in clue order, spell out the source of the quotation (sometimes abbreviated).

Fill-a-Pix

This is a logic puzzle very much like the Minesweeper game but all the clues you are going to get are provided initially, and spaces with clues may also contain mines (in which case they include themselves in their count). Puzzles without this self-counting behavior are classified under Minesweeper instead.

football pool

A football pool is a gambling arrangement in which participants will buy squares in a 10x10 grid for a fixed price, typically initialing the squares they have bought. After the grid is filled, but before the game this pool is associated with begins, the organizer of the pool will randomly assign the ten digits to the rows and independently to the columns of the grid, one of these directions representing each team. The final digits of the final score (and in some pools, the score at the end of each quarter) will pay out the proceeds of the pool to the players who bought the corresponding squares.

fourteen-segment displays

The fourteen-segment display is the more advanced cousin to the more familiar seven-segment display. In this version, the horizontal bars are broken in half just as the vertical ones are, a new vertical bar is added in the middle, and four diagonal segments forming an X are added. This was an intermediate step between seven-segment displays and ones divided into individual pixels.

Funny Farm

The original Funny Farm is a game of graphical Word Association. Associated words are linked by a line, and all the words related to one that you have solved are indicated with boxes to be filled in. Due to there being many paths, you can sometimes get multiple clues to narrow down difficult words.

The first attempt to reproduce this in the Mystery Hunt was a puzzle called Funny Farm in 2011 that overloaded the Hunt server and had to be replaced by a backup puzzle.

jigsaw puzzles

(most of these are reconstructions of an image divided into rectangular pieces, rather than traditional jigsaw shapes)

jigsaw quote

The standard form of this puzzle consists of a 16x16 grid divided into 4x4 sections, into which a quote is to be written, with words wrapping around the ends of lines and black squares separating them. The letters to be filled in are provided, but the words and part-words within each 4x4 block are provided in sorted order, and the resulting groups are also provided in sorted order. Usually the different black squares in different sections distinguish most, but not all groups, and likewise the unique lengths of some letter strings within their groups allow some strings to be placed uniquely. Beyond that you have to figure out how to fit things so that they spell words.

Jumble puzzle

This puzzle, which is syndicated in many newspapers, consists of a set of scrambled words and a row of boxes to enter each one in, some of them containing circles.

jumping crossword

The jumping crossword is usually not a crossword in the conventional sense at all, since the word list is given. It's more like a criss-cross puzzle but with the extra rule that some squares will be left blank, with words simply reading across whichever letters are used (as opposed to a diagramless crossword where the unused squares mark word break). If there are black squares, they separate entries in the same row or column. In the original logic puzzle type jumping crossword, blank squares are not allowed to touch along an edge.

matchmaker puzzle

This puzzle type consists of two columns of things with dots next to each, and stuff in the middle. When you pair up the things correctly and draw lines between the matches, the stuff in the middle crossed by the lines spells out an answer. Many variations are possible depending on the things matched and what is in the middle; it's also possible the uncrossed middle-things are used (especially if letters). Mike Selinker uses this name for this puzzle type in Puzzlecraft.

math maze

Math maze is a path puzzle with Battleships-style clues that tell you how many squares in each row and column are part of the path. This makes it a relative of the snake puzzle but in math mazes only the head and tail are given and the path is allowed to visit squares adjacent to other parts of the path. The grid may have holes which divide rows and columns into parts; in this case clues apply to each part separately. Random Walk contains an example puzzle.

rebus

The most common kind of rebus is the one from the Concentration game show: A word or phrase is clued, partially or completely phonetically, via a series of smaller words, with plus and minus signs indicating how to combine the parts; they are combined in order, so the material to be removed by a minus part must exist in the result of the operation immediately before the minus sign. Any manipulation of words involving both adding and subtracting parts is classified here; for ones where parts are only added, see charades.

rebus crossword

A crossword puzzle in which more than one letter is to be written into some spaces, the rebus squares. Usually all the rebus squares are the same sequence of letters, or they are related somehow. Usually there are only a few of these (less than 5%), though they are not necessarily limited to long theme entries; if many squares contain multiple letters and there's no theme to those squares, it is a 1, 2, 3 crossword. The letters in rebus squares are usually meant to be read the same way across and down. This gimmick is usually not clued; solvers have to figure it out while solving.

River Crossing logic puzzles

This is for variations on the classic puzzle where a farmer is trying to cross a river with a wolf, a goat, and a basket of cabbages. He can't leave the wolf unattended with the goat, since it will eat the goat, nor can he leave the goat unattended with the cabbages, but his boat can only carry one of the three things besides himself. Even classically there are many variations on this.

The triangles are shaded in groups of 6 into hexagons (roses or blooms) of three different colors, no two same-colored hexagons touching. Clues are given for one word in each short row and usually exactly two words across each long row, and for the 6-letter words in each bloom.

Spiral Galaxies puzzle

This is the "rotator" puzzle, also called Tentai Show by Nikoli. A grid has some circles, which may be in the centers of cells, on the grid lines, or on the grid intersections. Divide the grid into regions so that each circle is in a separate region, all regions are rotationally symmetric, and each region has a circle at its center. Sometimes the circles are colored and you shade the regions in the resulting grid based on the circle colors.

stereograms

Stereograms are pairs of images intended to be viewed one with the left eye and one with the right eye while focusing so that the two images appear to lie in the same space. Small differences in the images create the illusion that some parts are above or below other parts. In the 1990s there was a popular series of what are called autostereograms - single images with repeating patterns that create the same sort of illusion; this is what usually appears in puzzles.

trigrams

Although trigrams can refer to any manipulation of groups of three letters, there is a common puzzle type where you have to unscramble and reassemble messages which have been broken up into trigrams after removing any spaces and punctuation. If the message does not have a multiple of three letters, the final one or two letters are typically left as they are and placed at the end of the list of trigrams (which is typically alphabetized). In other cases the message(s) may be crafted to have a multiple of three letters so that there is no leftover. In still other cases, the puzzle may not be restricted to groups three letters long, but works in a similar way.

word stack

A word stack is a grid for a list of related words arranged so that some matching letters fall in the same columns; these letters get a single tall box to indicate the repetition. The words may be arbitrarily staggered left or right, and sometimes arbitrarily ordered, in order to increase the number and height of these shared letter boxes. Usually only a few letters are initially given.

Xzibit

Xzibit is the celebrity associated with the Internet meme "Yo dawg, I heard you like X so I put a X in your X so you can Y while you Y." It's based on his time as host of the MTV television series "Pimp My Ride" in which he said similar things about what he had installed in cars (where the last X was usually "car" and the last Y was usually "drive"). The meme version makes all the Xs the same, so that you're putting something inside itself, or another of the same thing.
