Enter word-clue pairs and click “Generate Crossword” to create your puzzle
Type your words and the clue you want beside each one, and this free crossword maker finds a layout where they cross. The grid is numbered for you and split into Across and Down lists, exactly as students expect a crossword to look. Print the blank puzzle straight from your browser, and download the answer key as a separate file so it never ends up on the students' copies. Words that share letters place most easily — if one cannot be fitted into the grid, the tool tells you instead of dropping it silently.

Why build your own crossword instead of downloading one
- The words are your words: this week's vocabulary, not a generic list
- You write the clues, so they match how the terms were actually taught
- The grid is generated, numbered and split into Across and Down for you
- Two word-clue pairs is the minimum and there is no upper limit
- Words that cannot be placed are reported rather than quietly dropped
- Print the blank puzzle straight from the browser
- The answer key downloads separately, so it never prints on the student copy
- Building and printing are open to everyone; the downloads ask for your email once
What teachers build crosswords for
End-of-unit vocabulary review
Clues written as definitions make students retrieve the term rather than recognise it in a list.
Revision before a test
A crossword of the terms most likely to appear is revision the class will actually finish.
Subject terminology
Science, history and geography vocabulary works well because the words are distinctive and long.
Explore toolEarly finishers and extension
Keep a printed set for students who are done before the rest of the room.
Homework that reviews the week
Send the puzzle home and keep the answer key for marking.
Cover lessons
A puzzle plus an answer key is a lesson someone else can run without briefing.
Explore toolWord work rotations
Run a crossword alongside a word search so stations stay varied.
Explore toolA change of puzzle format
Scrambles suit spelling; crosswords suit meaning — the same word list does both.
Explore toolFrequently Asked Questions
How many words can I include?
Add as many word-clue pairs as you need — two at minimum. The generator places as many as it can, prioritising words that share letters so the grid interlocks, and tells you if any could not be placed.
What if some words can't be placed?
The generator tries to place all words but some may not fit if they don't share letters with other words. You'll be notified of any unplaced words.
Can I use this for any subject?
Absolutely! Crossword puzzles work great for vocabulary in any subject — science terms, historical figures, literary devices, math vocabulary, and more.
