Crossword Puzzle Maker
A free crossword puzzle maker: choose a theme and a grid size, and it builds an interlocking crossword from real English words, with dictionary definitions as the clues. Solve it on screen, reveal the answers, or print a clean worksheet — no account needed.
Example puzzle: animal words
Here is a grid the generator built from the animal theme, with its answers shown. Yours will differ every time — this one is fixed so you can see what comes out before generating.

How the grid is built
Interlocking words is the whole problem. The generator places the longest word across the middle, then takes each remaining word and looks for every position where one of its letters lands on a letter already on the grid. A position is rejected if it would write a different letter on an occupied square, if it would sit flush against another word without crossing it — which creates stray two-letter pairs when read the other way — or if it would run off the edge. Of the positions that survive, it keeps the one with the most crossings, because a denser grid is a better puzzle.
What it deliberately does not do is chase the symmetry of a newspaper grid. Rotational symmetry with a fixed black-square pattern is a constraint-solving problem, and pursuing it would mean either far fewer words placed or a much slower generator. For a worksheet or a classroom warm-up, an asymmetric grid that uses more of your theme is the better trade — so that is the one this tool makes.
Using it in a classroom
A themed crossword is vocabulary practice that hides the drill: to fill a square a pupil has to read a definition, retrieve the word, and then check it against the letters its neighbours already fix — three passes over the same word instead of one. That is why the clue here is a real dictionary definition rather than a riddle; the exercise is meaning-to-word recall, not lateral thinking.
Two practical habits. Generate the grid, print it with the answers hidden, then reveal and print again — the second sheet is your answer key, and it takes ten seconds. And pick the grid size to match the group: 11 × 11 packs fewer, shorter words and suits younger pupils, while 15 × 15 leaves room for the longer vocabulary that makes a puzzle worth a full lesson slot.
Frequently asked questions
- How does this crossword puzzle maker work?
- Pick a theme and a grid size, and the generator draws real English words from that theme, looks up a dictionary definition for each one to use as its clue, then interlocks them on the grid — longest words first, each new word crossing a letter already placed. The result is a blank grid with numbered Across and Down clues, ready to solve or print.
- Can I use my own words?
- Not yet — clues come from the dictionary, so the words have to be ones we hold a definition for. That constraint is what makes the puzzle solvable without you writing 20 clues by hand. If you need a specific word list, generate a themed grid and use it as a starting point.
- Why are some words left out of the grid?
- A word only goes in if it can cross a letter already on the grid without touching another word sideways, which would create nonsense letter pairs read the other way. Words that share no usable letter with what's already placed are reported as left out rather than forced in. Generating again reshuffles the order and usually places a different set.
- Can I print the puzzle?
- Yes. The print button gives you the grid and the clue list on paper, with the site's navigation, buttons and ads stripped out. Leave the answers hidden before printing and you get a clean worksheet; reveal them first and you get the answer key.
- Is it really free?
- Yes — no account, no watermark, no limit on how many puzzles you generate. The words come from Princeton WordNet and pass through a family-friendly filter by default.
