A crossword is a sophisticated word game played within a grid of black and white squares.

Solvers enter words or phrases, known as entries, into the white squares. These entries must cross each other both horizontally, called "across," and vertically, called "down." Black squares serve to separate these individual entries. Every white square typically holds a single letter. To help the solver, the first white square of an entry is numbered. This number corresponds to a specific clue found in a list outside the grid. People who participate in this hobby are called cruciverbalists. This term was likely created in the 1970s. It combines the Latin words "crucis," meaning cross, and "verbum," meaning word.

Modern crossword construction is a precise process that often uses specialized software. A constructor, or creator, begins by choosing a theme for the puzzle. In many cases, they place long theme answers into a grid first. Most American grids are designed with 180-degree rotational symmetry. This means the pattern of black and white squares looks identical if you turn the paper upside down. After placing the theme, the constructor fills the remaining white squares with words. Finally, they write the clues that guide the solver. Most designs also require that all white cells are orthogonally contiguous. This means all the white squares are connected in one single mass through their sides.

There are several distinct styles of crossword grids used around the world. American-style crosswords are characterized by solid regions of uninterrupted white squares. In these puzzles, shaded squares usually make up only about one-sixth of the total grid. A key rule here is that every letter must be "checked." This means every letter is part of both an across word and a down word. In contrast, grids used in Britain, Australia, and India often have a lattice-like structure. These grids contain more shaded squares, roughly 25 percent of the total. This higher number of black squares means about half of the letters remain unchecked.

Other unique variations exist beyond the standard grid. Barred crosswords use bold lines between squares instead of shaded squares to separate entries. Some puzzles use circular designs where answers are entered in concentric circles or radially. You may also find "free form" or "criss-cross" puzzles. These have simple, asymmetric designs often found on children's menus or school worksheets. Some even use grids that form shapes other than squares.

The history of the modern crossword began in the 1910s. The New York World newspaper helped popularize the earliest forms that resemble what we play today.

Puzzles come in many standard sizes depending on their purpose. Many weekday newspaper puzzles, such as those in The New York Times, use a 15×15 grid. Weekend puzzles are often much larger, reaching sizes like 21×21, 23×23, or 25×25. In the United States, difficulty levels often follow a weekly schedule. Monday puzzles are the easiest, and the difficulty increases each day until Saturday. This is why solvers use days of the week as shorthand for difficulty. A "Monday" is an easy puzzle, while a "Saturday" is a very difficult one.

Clues are the essential tools for solving, and they follow strict conventions. In American-style puzzles, most clues are "straight" or "quick" clues, which act as simple definitions. However, clues must always agree with the answer in tense, number, and degree. For example, a past-tense clue like "Traveled on horseback" requires the answer "RODE" rather than "RIDE." Some clues use wordplay, often signaled by a question mark at the end. A clue like "Grateful?" might lead to the answer "ASHES" because a grate can hold them.

Solvers also use "checks" to confirm answers. If a clue is "PC key," the answer could be ESC, ALT, or TAB. The intersecting words provide the letters needed to find the correct choice.

Themes add a deeper layer of complexity and connection to the game. A theme might consist of several long entries that share a common relationship. For instance, a category theme might use several synonyms for the word "black." Other themes might use famous quotes broken into parts. Some even use a "rebus," where multiple letters or symbols occupy a single square.
