MIT Mystery Hunt Puzzle Index: Full Index

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:

Crushword is a variant with no upper limit on the number of letters, though some sources use this name for the 1, 2, 3.
Variogram forms in the NPL are also one or more.
The jumping crossword allows 0 or 1 letters.
Double-or-nothing 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 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

alphacode

See Alphacipher

alphagram

In the standard version of this puzzle type, 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. Sometimes (as in a Double Alphabet Soup or 52-skiddoo) there are two columns each to be filled with the alphabet).

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.

Anglers logic puzzle

In the standard variety of this puzzle type, a grid is given with fish in several squares and numbers representing fishermen (anglers) appear outside the grid on all edges. You are to draw nonoverlapping paths from each angler to a fish using only orthogonal steps, and covering exactly as many grid cells (including the one with the fish) as the number at that angler. The numbers sum to the number of grid cells, so every cell must be used.

Balance Loop logic puzzle

In this closed-loop-drawing puzzle, the loop passes through all the cells with circles. At white circles, the line travels the same number of cells on either side of the circle before turning, and at black circles, it travels a different number of cells on each side before turning. A number on the circle tells the sum of the straight segments on each side of the circle up to the next turn, even if the path goes through other circles before turning.

MIT Mystery Hunt 2022 Dancing Triangles

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.

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. Classically (because of old Latin rules) the Baconian cipher 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, a simple form of steganography, which might involve writing letters or words in two different styles to encode the binary. The Baconian cipher was classically used in this way. 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.

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.

Effectively, when flattened, the puzzle is equivalent to a grid of squares which have been cut in half diagonally in alternate directions, with words reading in the rows and columns. You could think of it each square having two letters, but the squares alternate as to whether the letters are read in the same order both directions, or in opposite orders.

Cheryl's Birthday problem

This is a kind of information deduction problem. Two people are each given incomplete information about some fact (in the original, the month and day of Cheryl's birth) and they make statements which progressively reveal more information to the other. Both the solver and the other character make deductions based on the idea that when one character does not know something, it means there are still two possibilities with all the information that character knows (including half the answer).

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.

Corral puzzle

The standard form of this puzzle is a grid with numbers in some cells. A single closed loop is to be drawn along the edges of the grid so that all the numbers are inside the loop, and the number of squares in the row and column through each number, going up to the first part of the loop encountered in each direction, and counting the cell with the number once, equals the number. The instructions for Cave have you shade in the cells outside the loop, but with rules which make it functionally the same puzzle.

This refers to words which often appear in American-style crosswords, while being rare in typical English. Usually these are words which start and end with vowels, or have many vowels, as grids often require such words and there are far fewer of these than other patterns.

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.

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.

curved line nonogram

This is what it sounds like. It works much like a standard nonogram except the lines aren't straight. There are numbers on one side of each end of each line which tell the lengths of the consecutive groups of boxes on that side of the line which are shaded - but the boxes may have more or fewer than 4 sides!

false negatives

A false negative is a word that begins with the letters that form a prefix which negates a word, for which the prefix letters may be removed to yield another word, but where the prefix is not actually a prefix and the words are actually unrelated. This is a specific puzzle type in the National Puzzlers' League (where it is generalized to other types of falseness) but the concept is used elsewhere as well. See also false comparatives.

false plurals

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.

The standard form of this puzzle consists of a grid where some cells initially have a number. To solve it, fill numbers into the remaining cells so that each orthogonally connected group of the same number consists of as many cells as that number.

The characters normally used for writing numbers in Chinese are easy for a forger to manipulate by adding strokes to change the numbers into other numbers. To prevent this, another system of writing numbers is used in financial contexts which are more complicated and not easy to manipulate in this way.

flats (NPL puzzles)

These are verse puzzles where the answers are words with some sort of wordplay relationship, and they are missing from the verse (typically replaced by other all-caps words, the cue words, which, when necessary, explain which word goes where). The wordplay relationships which flats use can appear in other types of puzzles without the actual verse that makes the puzzle a flat. Many of the wordplay types can be found as their own keywords in the Wordplay category including backswitches, charades, consonantcies, deletions, false flats, heteronyms, homophones, letter banks, letter changes, letter shifts, palindromes, rebuses, reduplications, reversals, and spoonerisms.

The original puzzle by this name is where you write some some string of letters and follow a complicated series of steps (such as moving the second consonant to the end) to transform it into something else. Some of these puzzles are essentially like this, but this is Mystery Hunt, so some are vastly more complicated. See also Duck Konundrum.

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.

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.

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.

Futhorc

The writing system used to write Anglo-Saxon language roughly from the 5th to 11th centuries, gradually being phased out in favor of the Latin alphabet. The Futhorc developed from an earlier, nearly identical writing system called the Elder Futhark, used primarily in Scandinavia, which dates back to the 2nd century AD, and which was later simplified to the Younger Futhark. These writing systems are what people usually refer to when they speak of "runes," and a runestone is simply a stone which was engraved with runes.

Hayden elephant mural

This mural appears just outside Hayden Library at MIT. It shows several men trying to describe an elephant, and is perhaps a version of the parable of the blind men and an elephant, in which each man feels a different part of the elephant, describes it to the other blind men, and they argue over the true nature of the elephant because of the different perceptions of it they have had.

Honeycomb crossword

The grid for this crossword uses hexagonal cells. Numbers appear in black cells and each answer is written in the six hexes around it, with the starting square and direction for each answer left to the solver to determine based on matching letters from adjacent words. There are two variations: In one, the grid is rectangular and the numbers lie in a rectangular lattice of cells. In the other, the grid is hexagonal and the rows of numbered cells are staggered so that every pair of adjacent words shares two letters. Old Dell magazines used to run both versions, calling the hexagonal-shaped grid Inner Circles.

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.

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. But in Mystery Hunt we have generally had jumping crosswords that are clued like crosswords.

The standard form of this Latin square puzzle consists of a grid divided into a number of heavily outlined regions, each of which contains a small clue number and a mathematical operation. The grid is to be filled in with the numbers from 1 to N, not repeating a number within a row or column, such that the result of applying the operation in each region to the numbers filled into that region equals the clue number. IN some variants the operations may be omitted and only the numbers given.

keyed-order crossword

This crossword variant has a rectangular grid with winding marked paths on which some answers go, but you're not told which goes on each path nor in which direction it reads. Some (but not all) rows have clues for usually two words that are entered there, but they don't go in order; instead, numbers 1 to N in the cells tell which order to enter the letters in the row. Foggy calls this a Vine Garden, but I don't see any other use of the name.

A Nikoli puzzle type featuring a grid with circled numbers in some cells. The clues have the same meaning as in corral, each indicating the total number of squares, including itself, that you can see looking in the orthogonal directions up to the edge of the grid or the first wall. In this case, the walls are isolated black cells which cannot touch orthogonally. The white cells must remain a single orthogonally connected group. The English name for this puzzle, "where is black cells?" has bad grammar, and could describe dozens of puzzles, but is nevertheless the name used.

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.

mirror logic puzzles

In the standard form of this puzzle, you have to determine where to place two-sided mirrors at either or two diagonal directions in some cells, so that each pair of identical clues outside the grid is connected by a path of orthogonally connected cells through the grid which bends at (and only at) mirrors, in the directions which do not cross the mirrors. A path may use the same cell twice (either passing straight through an empty cell twice in different directions, or bouncing off both sides of the same mirror)

phonespell (2 = A,B,C)

Classically, phonespell was used to provide words that encode to the correct phone number when the indicated keys are pressed. It was also for many years a puzzle where only the digits are provided and you have to decipher the message. In modern times (on devices without touchscreens) it's used in reverse and called T9: You press the keys for the letters in a word and the phone determines what word is the most common one spelled with those numbers (replacing multi-tap, an earlier method in which you pressed 2 once for A, twice for B, and three times for C).

rebus

The most common kind of rebus is the one from the Concentration game show: A word or phrase is clued, often 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, though there can be variants where they are read one way afross and another way down. This gimmick is usually not clued; solvers have to figure it out while solving.

redox reactions

Chemical reactions in which an element in one reactant is reduced, while an element in another reactant is oxidized. In this sense, "reduced" means the oxidation state or valence state is lowered, while "oxidized" means the oxidation state is increased. This type of reaction is associated with a transfer of electrons from the oxidized element to the reduced one.

reduplications

A word is repeated two or more times to form a longer word (like yo, yo-yo).

A phonetic form of reduplication is called a Word Avalanche on Reddit.

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.

This most commonly refers to Linnaean binomial nomenclature, the system by which every genus and species pair is chosen to be unique across all life. However, it can refer to any named applying to any level in the classification system. Traditionally, that system had seven levels: Kingdom, Phylum, Class, Order, Family, Genus, and Species. In modern times, Domains or Empires have been proposed as supersets over the Kingdoms, and various sub- and super- variants inserted into the tree to account for branches in evolutionary development.

spoonerisms

Named for a Reverend Spooner who tended to mix up words like this on accident, a spoonerism is the swapping of initial consonant sounds in the words of a phrase. Generally, if a word starts with a consonant cluster such as BL or STR, the entire cluster is swapped. Sometimes a small connective word in the phrase is unchanged, as in WHACK AND BLIGHT for BLACK AND WHITE. Sometimes the initial consonant sounds of three woirds are rotated among the three words. The NPL uses this as a flat type called a spoonergram.

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.

The standard word search is a grid of letters, within which a provided list of words is hidden, each one in a straight line in one of 8 directions (orthogonally or diagonally). Frequently the unused letters spell a final message. In World Puzzle Championship usage, the words may extend into a region where the letters are omitted and your goal is to identify all the missing letters (which are all used in at least one word), and this kind may show up in Hunts as well.

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."
