A crossword maker (also called a crossword creator or generator) usually takes a list of words and clues and arranges them into a free-form grid, which suits classrooms and quick puzzles. A crossword constructor is software for building a newspaper-style grid yourself: symmetric black squares, every letter crossing two words, and help filling the grid. Gridsmith is a constructor, so it fits New York Times-style puzzles and not vocabulary worksheets.
What is the difference between a crossword maker and a constructor?
The names get used interchangeably, but the two kinds of tool start from opposite ends.
A word-list generator starts with your words. You type or paste a list of answers and clues, press a button, and the tool packs them into a grid. Not every word has to cross another, and the black-and-white pattern is whatever the packing produces. The result is a valid puzzle, but it doesn't look like the one in a newspaper.
A constructor starts with the grid. You decide the shape first, then place answers into it, and the software checks your work: that the pattern is symmetric, that every white square is part of an across and a down word, and that the words you choose actually fit their crossings. The words come second, and that is the hard part of the craft.
| Word-list generator | Constructor | |
|---|---|---|
| You provide | A list of words and clues | A grid pattern, then theme answers |
| Grid shape | Whatever the packing produces | Your choice, usually symmetric |
| Every square crossed twice | Not required | Standard in American-style puzzles |
| Black-square symmetry | Rarely | 180° rotational, automatic in good tools |
| Fill help | Not needed; the tool picks the layout | Suggestions and autofill for open slots |
| Best for | Classrooms, worksheets, party puzzles | Puzzles you want an editor to read |
| Time to a first puzzle | Minutes | Hours for a first attempt |
When should you use a word-list crossword maker?
Use a generator when the words are the point. A teacher building a review puzzle on the water cycle, a parent making a birthday puzzle with family names, or a club making a puzzle from its own jargon all have a fixed vocabulary. Forcing that vocabulary into a symmetric, fully interlocked grid would be slow and would probably mean dropping some of the words.
Free-form tools are also built around classroom printing and sharing. Examples include Discovery Education's Puzzlemaker and Crossword Labs. Check each tool's own page for current features and limits, since they change.
If that is your goal, a generator is the right choice, and Gridsmith's own free crossword generator needs no account. Gridsmith won't make a vocabulary worksheet well, because it doesn't generate a layout from a word list.
When do you need a crossword constructor?
Use a constructor when the grid itself has to meet a standard. That usually means one of three things:
- You want to submit a puzzle. Outlets such as the New York Times expect symmetric, fully interlocked grids with set sizes and word-count limits. See the grid rules and the NYT submission guide.
- You want it to feel like a real crossword. Solvers who do a daily puzzle notice when the pattern is lopsided or when words dangle off the edge.
- You enjoy the craft. Choosing a theme, fitting long answers and polishing the fill is the part constructors like.
The extra rules are what make a crossword a crossword in the American style. They are covered in how to make an NYT-style crossword.
What does a constructor do that a generator doesn't?
Three things matter most.
It enforces the pattern. In a constructor, placing a black square also places its mirror image across the center, so the grid stays symmetric without counting by hand. Numbering updates as you edit.
It helps you fill. Once your theme answers are in, the grid is mostly empty slots with letters already set by their crossings. A constructor can list the words that fit a slot, ranked by quality, and can try to fill several slots at once. How that works, and where it struggles, is explained in crossword autofill.
It uses a word list you control. Fill quality depends on the list behind it. A scored list lets the tool prefer lively, familiar words over obscure ones. See crossword word lists.
Is Gridsmith a crossword maker or a constructor?
Gridsmith is a constructor. It runs in a desktop browser with nothing to install, and these are the facts that decide whether it fits you:
- Two grid sizes: 15×15 (daily) and 21×21 (Sunday). No custom sizes or minis.
- 180° rotational symmetry is applied automatically when you place blocks, and numbering is live.
- The active slot shows ranked suggestions that agree with its crossings. You can autofill one word or the whole puzzle. Filling a blank grid can be slow, so type your theme entries first.
- You can import your own scored word list, and clues sit beside the grid.
- Building, filling, clueing, saving and unlimited puzzles are free, with JSON export. Gridsmith Plus ($4.99/month or $39.96/year) adds .puz export and import and print/PDF.
It doesn't support rebus squares, barred or cryptic grids, collaboration or phone editing, and it can't publish puzzles for solvers to play. If you need to share a puzzle with solvers, export it and use a site built for that.
Which crossword software should you pick?
Match the tool to the job:
| Your goal | Tool type | Where to look |
|---|---|---|
| A vocabulary or party puzzle in minutes | Word-list generator | Any free-form crossword maker |
| A first newspaper-style puzzle, in a browser | Constructor | Gridsmith or Crosshare |
| A tool you install and keep for years | Desktop constructor | Crossfire or Crossword Compiler |
| A puzzle published for solvers to play | Constructor with publishing | Crosshare |
| Many options compared | Roundup | Free crossword construction software |
None of these is the single best choice. A teacher is better served by a generator, and a would-be New York Times constructor is better served by a constructor.
How do I start making a crossword puzzle?
If you decided on a constructor, the order that works is: pick a theme, place the long theme answers, add blocks symmetrically, fill the rest, then clue it. The full walk-through is in how to make a crossword puzzle. To skip straight to a grid, open Gridsmith and pick 15×15.
Frequently asked questions
What is the difference between a crossword maker and a crossword creator?
In practice, nothing. Both names usually describe a tool that builds a puzzle from your input, and sites use them interchangeably. The distinction that matters is whether the tool arranges a word list for you (a generator) or helps you build a symmetric grid yourself (a constructor).
Is there a free crossword puzzle maker?
Yes, several. Free-form generators are free for basic puzzles, and constructors such as Gridsmith and Crosshare are free to start. Gridsmith is free to build, fill, clue and save, with .puz export and print/PDF in a paid tier. Always check each site's current limits.
Can a crossword generator make a New York Times-style puzzle?
Generally not on its own. Word-list generators don't enforce symmetry or full interlock, which are expected for newspaper submissions. A constructor helps you meet those rules, but the quality of the theme and fill still depends on you.
Can I make a crossword from a list of words in Gridsmith?
Not in the way a generator does. Gridsmith doesn't arrange a list into a layout. You choose the grid and place entries, and the fill tools help with the rest. For a quick vocabulary puzzle, use a word-list maker instead.
Do I need to install anything to make a crossword?
Not with a browser tool. Gridsmith and Crosshare run in a browser. Crossfire and Crossword Compiler are desktop programs you install.
