Understanding the Puzzle Types
American Crosswords
Crossword grids such as those appearing in most North American newspapers and magazines feature solid areas of white squares. Every letter is checked, and usually each answer is required to contain at least three letters. In such puzzles shaded squares are traditionally limited to about one-sixth of the design. Crossword grids elsewhere, such as in Britain and Australia, have a lattice-like structure, with a higher percentage of shaded squares, leaving up to half the letters in an answer unchecked. For example, if the top row has an answer running all the way across, there will be no across answers in the second row.
Another tradition in puzzle design (in North America and Britain particularly) is that the grid should have 180-degree rotational symmetry, so that its pattern appears the same if the paper is turned upside down. 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).
Cruciverba svedesi
La griglia stile svedese non utilizza numeri di definizione, le definizioni sono contenute nelle caselle che normalmente sarebbero nere in altri paesi. Le frecce indicano in quale direzione bisogna rispondere alla definizione, verticale o orizzontale. Questo stile della griglia è utilizzato in parecchi paesi oltre alla Svezia, di solito in riviste con pagine in formato A4 o simili. Spesso la griglia include, come definizione di una risposta, una foto di un attore famoso o di un cantante al posto di parte delle caselle. Questi cruciverba di solito non hanno una griglia simmetrica.
Crosswords with clue cells inside the crossword grid are also called Arrowwords, Pointers or Tipwords in English, Autodefinidos in Spanish, Mots Fléchés in French, etc.
Crossnumbers
A crossnumber (also known as a cross-figure) is the numerical analogy of a crossword, in which the solutions to the clues are numbers instead of words. Clues are usually arithmetical expressions, but can also be general knowledge clues to which the answer is a number or year. There are also numerical fill-in crosswords.
The Daily Mail Weekend magazine used to feature crossnumbers under the misnomer Number Word. This kind of puzzle should not be confused with a different puzzle that the Daily Mail refers to as Cross Number.
Number Puzzles
Number puzzles are a variant of crosswords in which each cell has a number between 1 and 26. The solver has to find out for which letter of the alphabet a number stands.
Free Crosswords
This is a special type that tries to be least restrictive. You can use all available cell types (eg. clue cells, double clue cells, image cells, solution letter cells). You can mix answers that have a clue cell with answers that don't. Answers may contain characters as well as numbers.
