What is a crossword puzzle maker?

A crossword puzzle maker turns a list of answers and clues into a crossword grid. It connects each word to the others where they share a letter, numbers the starting squares, and writes the Across and Down clue lists. Teachers use crosswords for vocabulary and spelling review, parents for screen-free fun, and hosts for baby shower, wedding and holiday games.

CrosswordNest builds free-form crosswords: it places the longest words first, tries dozens of arrangements and keeps the one with the most crossings and the most compact, balanced shape. Two letters only touch when they belong to the same word, so every row and column reads correctly, and words that cannot connect are listed so you can swap them.

How to make a crossword puzzle

  1. Type your words and clues. Enter a title, then one answer per line followed by a dash and its clue, like "Whale - Largest animal on Earth". Up to 40 words.
  2. Let the maker build the grid. Every word is connected to the others, the squares are numbered and the Across and Down clue lists are written for you. Click New layout for another arrangement.
  3. Choose the options. Add a word bank, show or hide letter counts, or switch to Word scramble mode to turn the same list into an unscramble worksheet.
  4. Print, save or play. Click Print / Save PDF for the puzzle on page 1 and the answer key on page 2, download a PNG, or click Play online and Check answers.

Frequently asked questions

Is this crossword maker really free?

Yes. Making, printing, saving as PDF, downloading PNG images and playing online are all free, with no account, no watermark and no limit on how many puzzles you make.

How do I enter words and clues?

Put one word per line, followed by a dash and the clue, for example "Whale - Largest animal on Earth". A colon, equals sign, tab or comma also works. Words without a clue appear in a word bank.

How many words can a crossword have?

Up to 40 words, each up to 25 letters. Ten to twenty words is the best size for one printed page. The grid grows to fit, up to 25 squares wide and tall.

Why was one of my words left out?

Every word in a crossword must cross another word, so a word needs at least one letter in common with the rest of the list and a free spot where it fits. The maker tells you which words could not be connected; click New layout or add a word that shares letters with them.

How do I print the crossword with the answer key?

Click Print / Save PDF. Page 1 is the puzzle with numbered squares and the Across and Down clues; page 2 is the answer key with every square filled in. Choose "Save as PDF" in the print dialog to keep a file.

Can students solve the crossword online?

Yes. Click Play online to type into the grid, then Check to mark wrong letters in red. Copy link creates a web address that contains the whole puzzle, so students open exactly the same crossword.

What is the word scramble mode?

It turns the same word list into a word scramble worksheet: each word's letters are shuffled, with an answer line, the optional clue underneath and an answer key on page 2.

Are my words uploaded anywhere?

No. Puzzles are generated in your browser. When you copy a link, the words are stored after the # in the address, which browsers never send to the server.
