A word ladder turns one word into another by changing a single letter at a time, and every rung has to be a real word. This maker builds one in a few seconds — play it on the whiteboard, or print an A4 sheet of 4, 6 or 8 puzzles to hand round.
You choose how the words get picked. Free Play hands you a pair, Target Word lets you set the finish yourself, and the topic mode themes the words around whatever you happen to be teaching. Every ladder is solved before it reaches you, so an impossible puzzle never goes up on the board.
Pick a mode, choose how long the ladder should be, then generate and preview it. It takes under a minute, and the preview screen shows you the finished ladder before anyone else sees it — so you can regenerate quietly if the words are wrong for your class.
Ladders come in short, medium and long. Short is the one to reach for when the point is the spelling pattern rather than the puzzle; long is the one that turns into a genuine thinking task and will eat ten minutes if you let it.
Match the ladder to what you want them thinking about, not to how clever the class is. A short four-letter ladder is a phonics task; a long six-letter one is a reasoning task that happens to use spelling.
| Ladder | Year group | What it actually practises |
|---|---|---|
| Short, 4 letters | Year 1–2 Grades 1–2 |
Hearing which sound changed, and holding the rest of the word steady while it does |
| Medium, 4–5 letters | Year 3–4 Grades 2–3 |
Vowel swaps and the common spelling patterns that sit either side of them |
| Long, 5–6 letters | Year 5–6 Grades 4–5 |
Working backwards from the target and juggling two constraints at once |
Yes. Worksheet mode builds an A4 PDF of 4, 6 or 8 puzzles and opens it in a new tab, ready to photocopy. Nothing is watermarked and nothing is held back for a paid plan.
Set the sheet to ramp and it opens with a short warm-up ladder and finishes on a challenge, which is the version worth printing if the class works at different speeds — the early finishers reach the hard one instead of running out of sheet.
Because no chain of real words connects them. The app searches a bundled list of 4,050 common words — 1,021 of four letters, 1,362 of five and 1,667 of six — and looks for the shortest path between your two. If every route needs a word that isn’t on that list, there is no ladder to build and it says so rather than inventing one.
The fix is usually a small one: change one of the two words, or drop to a shorter length. Target words have to be 4 to 6 letters and letters only, for the same reason — anything outside that range has nothing to connect to.
Two letters at once. The commonest wrong answer isn’t a wrong word, it’s a right word reached illegally. Reading the rung back aloud against the one above it catches nearly all of them, and it puts the checking on the class rather than on you.
The word that isn’t a word. Someone will offer a plausible non-word and defend it well. Worth deciding in advance whether names, plurals and abbreviations count, and saying so before the first rung rather than arbitrating mid-puzzle.
The child who sees the whole ladder immediately. A word ladder is over the moment one person calls out the answer. Covering the target word and revealing it only at the end keeps it a reasoning task instead of a race, and gives everyone else the thinking time the puzzle is actually for.
Building ladders and printing the worksheet are free and spend no tokens — Free Play, Target Word and the printable A4 sheet all cost nothing, however many you make. The only part that uses a token is the AI topic mode, which invents themed words around a subject for you. You need a free account to generate, so your ladders are there when you come back.
What is a word ladder?
A word ladder is a puzzle where you change one letter at a time to get from a start word to a target word, and every rung must be a real word — for example COLD → CORD → CARD → WARD → WARM. They were invented by Lewis Carroll.
How do I make a word ladder puzzle?
Pick a mode — free play, a topic, or set your own target word — then generate and preview. Coach the class through it on the whiteboard or print an A4 worksheet.
Can I print word ladder worksheets?
Yes — the worksheet mode builds an A4 PDF of 4, 6 or 8 word ladder puzzles, ready to photocopy. Set it to ramp and the sheet opens with a short warm-up ladder and finishes on a challenge.
Can I choose the start and end words?
Yes — Target Word mode lets you set the end word. It must be 4 to 6 letters and letters only, because the solver works over a bundled list of common 4, 5 and 6 letter words.
What is a good word ladder for kids?
Short three- or four-letter ladders work best — for example CAT → COT → COG → DOG, or COLD → CORD → CARD → WARM.
Why won’t it accept my two words?
Because no chain of real words connects them. The app searches a bundled list of 4,050 common words for the shortest path, so if every route passes through a word that isn’t on the list, there is no ladder to build.
Is the word ladder maker free?
Yes. Building ladders and printing the A4 worksheet are free and use no tokens. Only the AI topic mode, which invents themed words for you, spends one.
