Tips for better results
Use words that share letters
Crosswords interlock best when words have common letters, so a varied list crosses more cleanly.
Keep clues short and clear
One short, specific clue per word reads best on the page and is easier for students to solve.
Avoid too many very long words
A mix of short and medium words fits and crosses more reliably than several long ones.
Use a larger grid for longer lists
If some words won't fit, switch to a bigger grid so there's room for everything to interlock.
Regenerate for a better layout
Press Regenerate to try a fresh arrangement. Some seeds pack the words together more neatly.
Print the answer key separately
The PDF puts the filled-in answer grid on its own page, so you can keep it apart from the student copy.
How the crossword puzzle maker works
Type one word and clue per line. The tool accepts a few simple formats, so you can separate the word from its clue with a dash, a colon, a vertical bar, or a tab. It trims spaces, skips blank lines, makes the grid words uppercase, removes punctuation from the words, and can remove duplicates, while keeping your clue text exactly as you wrote it.
To build the puzzle, the tool starts with a longer word and then fits the rest around it, crossing words wherever their letters match. It follows real crossword rules, so words never run together end to end and a new word never sits right alongside another. It tries several arrangements and keeps the one that places the most words in the neatest, most connected grid, then numbers the clue starts and sorts them into Across and Down lists.
Everything happens on your device, so you can regenerate fresh layouts as many times as you like, instantly and for free. If a word is too long for the grid, or some words can't be crossed in, the tool tells you and suggests a quick fix.

How should I format words and clues?

What if some words do not fit?
If a word can't be crossed into the grid, the tool lets you know. Try a larger grid, fewer or shorter words, or words that share more letters, and press Regenerate for a new layout.
Are my words and clues uploaded or saved anywhere?
