About this crossword maker

Everything runs in your browser — no account, no watermark, unlimited puzzles. The generator tries dozens of arrangements and keeps the one with the most crossings in the smallest grid, so every word is linked to the rest. Numbers follow the usual rule: squares are numbered left to right, top to bottom, wherever a word starts. The same words, grid size and puzzle number always give the same layout, so a copied link or a noted number brings back exactly the same crossword.

How to make a crossword here

Write one entry per line in the form “word - clue”. A colon or a tab works as well, so you can paste two columns straight from a spreadsheet. Spaces inside an answer are removed (ICE CREAM becomes ICECREAM, as in printed crosswords), and in English and Spanish grids accents are dropped while Ñ stays a letter of its own. Korean answers use one syllable per square, so 고양이 takes three squares. The puzzle rebuilds a moment after you stop typing.

Words are crossed automatically. The generator tries dozens of arrangements and keeps the one where the most letters are shared inside the smallest grid. Every word after the first must cross at least one other word, so the whole puzzle is a single connected block, and words never touch side by side in a way that would spell an accidental extra word. If a word cannot find a crossing, it is listed above the puzzle instead of being placed on its own.

Writing good clues

A clue should point to one answer only. “Fruit” fits a dozen words; “Yellow fruit you peel” fits one. Definitions, opposites (“The opposite of cold”), fill-in-the-blank sentences (“A ___ a day keeps the doctor away”) and short facts (“Capital: Lima”) all work well, and mixing the types keeps a puzzle lively. The word length shown after each clue is a strong help in itself, so you can switch it off for a harder puzzle.

Keep clues short enough to read at a glance — the generator shortens anything over 80 characters so the clue list still fits on the page. Words that share common letters (vowels in English and Spanish, common syllables such as 이, 기 or 리 in Korean) cross more easily, so a list of eight to fifteen words usually gives the neatest grid.

Using crosswords in class and at home

A crossword turns a vocabulary list into retrieval practice: to fill the squares, the solver has to recall the word and spell it exactly, which is harder — and more useful — than recognising it in a list. Teachers often use the unit's key terms with their definitions as clues, so the same sheet reviews meaning and spelling at once. For language learners, write the clue in one language and the answer in the other.

At home or at a party, themed puzzles work as quick activities: names of the guests for a birthday, places from a holiday, or inside jokes for an anniversary card. Print the puzzle and answer key together with “Print both”, or let people solve it on screen with “Solve on screen” and press Check to see how many words are right.

Frequently asked questions

Is it really free? Is there an answer key?
Yes — free, unlimited, with no watermark or sign-up. “Print answer key” prints a separate page with the grid filled in and all the answers listed by number, and “Print both” prints the puzzle and the key together. In the print dialog you can choose “Save as PDF”.
Why was one of my words left out?
Every word has to cross another one, so a word that shares no usable letter with the rest — or that is longer than the maximum grid — cannot be placed. Press “New layout” to try other arrangements, choose a larger grid, or add a word that shares letters with it. Words left out are always listed above the puzzle.
Can I make a crossword in Korean or Spanish?
Yes. Korean answers use one syllable per square, the way Korean crossword puzzles are usually printed. Spanish answers keep Ñ as its own letter and drop accents in the grid, which is the standard convention in printed crosswords; when you solve on screen, typing an accent is accepted as the plain letter. The clues themselves keep all their accents and punctuation.
How do I get the same puzzle again?
The layout depends only on the words, the maximum grid size and the puzzle number. Use “Copy link” — the link contains everything and opens exactly the same puzzle — or note the puzzle number and enter the same words later. With a theme, the link stays short.
Does it fit on one page?
Yes. The puzzle page is sized for A4: the squares and the clue text shrink automatically when there are many words or long clues, so the grid and all clues stay on one sheet, and the answer key prints on a second sheet. US Letter also works; if your printer adds margins, choose “Fit to page” in the print dialog.
How is this different from the word search maker?
In a word search the words are given and hidden among random letters, so it trains recognition and spelling. In a crossword only the clues are given, so the solver has to recall each word from its meaning — closer to a quiz. Many teachers use the word search for a first pass at new vocabulary and the crossword to check it later.
