Crossword Puzzle Maker

How to make it

1. Type a word and its clue on each lineWrite WORD: clue, for example ORBIT: A planet's path around the Sun. Up to 40 lines; an equals sign or a vertical bar also works as the separator.
2. Check the grid and the messageThe preview builds the crossword as you type. If a word could not connect to the others, the page names it so you can add a linking word.
3. Print the puzzle and keyPrint or download a PDF. Turn word lengths on or off, and print the answer key with the puzzle or on its own.

Typing words and clues

Each line holds one answer, a separator and the clue: PLANET: It goes round a star. A colon is clearest, but an equals sign, a vertical bar, or a dash with a space on each side also work, so a list copied from a document usually needs little cleanup. Capitals are not required for the answer; the grid uses capitals anyway.

Answers are built from the letters A to Z only. Spaces, hyphens and apostrophes are dropped, so SOLAR SYSTEM becomes an eleven-letter answer and X-RAY fills four squares as XRAY. Accented letters fold into their base letter, so CAFÉ is answered as CAFE. A line with no separator is left out, so check that every clue reached the lists. If you turn on Show word lengths in clues, that answer shows (11), not two numbers, so add two words to the clue itself if it helps. Clues can be up to 120 characters and wrap neatly in the clue columns.

How the grid is built and why a word may not connect

The maker starts with the longest answer and then hangs each of the others across it wherever they share a letter. It never places words side by side, so the grid has no accidental two-letter words, and every square belongs to an answer you wrote. It tries many arrangements and keeps the one that fits the most words in the most compact, square-ish grid.

A word can only join the puzzle if it shares a letter with a word already in the grid at a spot with room around it. Lists with lots of short words full of rare letters, such as JAZZ or QUIZ, sometimes leave one out. When that happens the page says Could not connect, names the words, and leaves the decision to you rather than printing a puzzle with a clue that has no squares. Usually adding one more word with common letters such as E, R, S, T and A gives the stragglers something to attach to.

Writing clues students can answer

The answer should be the only sensible fit for the clue and the number of squares. Before you print, read each clue on its own and ask whether a classmate could reasonably write a different word. Match the form of the answer too: a clue in the past tense needs a past tense answer, and a plural clue needs a plural.

For younger solvers, fill-in-the-blank sentences are the easiest clue type: We wear a ___ when it rains. Short definitions in the children's own words come next, then definitions taken from the unit's glossary. Older students enjoy clues that require a step of thinking, such as the opposite of ancient, or a word that rhymes with chair and grows on your head.

For a vocabulary review, write the clue as the definition and let the grid test the spelling: the student must produce every letter in the right order, which is harder than spotting the word in a printable word search. That is a good reason to use both in the same week, the word search first for familiarity and the crossword later for recall.

How many words to use for each age

Grade 1 and 2 children manage six to eight short answers well, with word lengths shown. Grades 3 to 5 can take ten to fifteen words. Middle school students are ready for fifteen to twenty-five, and adults happily solve thirty or more. A longer list makes a bigger grid with smaller squares, so for young writers keep the list short and the squares large enough for their letters. When the clues outgrow the sheet, they continue on an extra page headed clues continued instead of running off the bottom.

A tutor working with a fourth grader on the -tion ending might build a crossword of eight such answers, such as STATION, NATION and MOTION; each ending has to be written into squares that the crossing words check, so the spelling pattern cannot be skipped.

Review puzzles, class names and ESL

A crossword works at the end of a unit, when the vocabulary is familiar but not yet secure. It also makes a calm activity for the first week of school: put each child's first name in as an answer with a clue such as Has a pet rabbit and loves soccer, and the class learns names while solving. Names stay in your browser; only a copied link carries them, so share links with care, or use Share settings, which puts the example list in place of yours.

ESL teachers sometimes write the clue in the students' first language with an English answer, or use a picture description read aloud. If you already have the week's words saved, the Use this list in menu sends them here from the word search or from spelling word tracing, and you add a clue after each one. Going the other way, from the crossword to a word search or bingo, passes just the answers, without the clues. The same list can become vocabulary bingo cards for a livelier review.

Students also enjoy writing crosswords for each other. Ask a group to choose eight words from the unit and write a clue for each, type their lines into the maker, and swap the printed puzzles with another group. Writing a clue that has only one answer is a surprisingly good test of whether a student understands the word.

Checking a crossword before you print

Two minutes of checking saves a frustrated class. Read the Across and Down lists against your original list to confirm every clue is there; anything missing will be named in the Could not connect message above the preview. Then solve two or three entries yourself from the clues alone, without looking at your list, and fix any clue that could fit a different word of the same length.

Look at the shape too. A grid where one long word carries every other answer can feel thin; adding a medium-length word or two usually gives a denser, more interesting puzzle. If the squares look small for young writers, remove a few words or split the list into two puzzles, perhaps one for Monday and one for Thursday.

Answer key, variants and printing

The key page repeats the grid with every answer filled in, and the Answer key PDF button prints it on its own. New variant rearranges the same words into a different layout, useful for two classes or a retake. Each puzzle shows a Sheet number, and Copy link reopens that exact puzzle later.

Print at Actual size or 100% with browser headers and footers off. US Letter or A4 is chosen from your browser settings and can be changed; the title and the Name and Date line are both editable.
