Crossword Generator

How the free crossword generator saves planning time

Crosswords are one of the most reliable review activities in teaching: they force students to recall the definition, think about spelling, and check their own work because it has to fit. This generator takes your vocabulary list and clues and arranges them into a proper numbered crossword grid with a clean, printable layout.

You can write your own clues to match exactly what you taught, or let AI generate definitions at a grade level you choose - including ESL-friendly simpler wording. The generator handles the hard part (making the words interlock) so you never have to manually place words in a grid again.

Each puzzle prints with numbered across and down clues plus an answer key on a separate flow, ready for a substitute or a quiet review period.

How to use it

1. Add your words and clues, or generate the pairs with AI.
2. Let the tool arrange the grid and number the clues.
3. Preview, then print or download the PDF.
4. Use the answer key yourself or hand it to a student helper to check.
