How to use this
Pick a level and topic for a ready-made set, or ignore both and paste your own list — anything in the box overrides the buttons above it. Choose a difficulty, decide whether your class needs a word bank, and build.
The print button strips away the navigation and everything you are reading now, leaving a clean sheet. Uncheck the answer key before printing the student copies, then check it again and print one for yourself.
What makes this different
Three things, and none of them are about speed.
No puzzle has two answers
Before a scramble is shown, it is checked against every other word of the same length in the list. If the letters could also spell a different valid word, that arrangement is thrown away and reshuffled. This sounds minor until you have run the activity: HEAT and HATE share their letters, and a student who writes the other one is not wrong, which leaves you arguing about a worksheet instead of teaching.
Difficulty means something
Most generators randomise and call it done. Here two letters swapped moves a single adjacent pair, leaving the word almost intact — a beginner sees a nearly familiar shape and only has to spot one thing out of place. Fully mixed is the ordinary scramble. The gap between those two settings is the difference between a task a beginner can start and one they stare at.
The level is a real constraint
Ready-made sets stay inside the band you choose, so an A2 sheet does not quietly include a C1 word because it happened to fit the topic. Where a level has not yet been checked against a published wordlist it carries a warning mark rather than being presented as settled.
Advanced levels work differently on purpose
A plain scramble drills one narrow skill: reconstructing a written word from a disordered signal. That is genuinely useful up to about B2. By C1 it usually is not, because a learner at that level can already recognise written words fluently — their gaps are meaning, collocation and register, none of which rearranging letters touches.
So at C1 and C2 the format switches automatically to with definitions, and each scramble prints alongside a short gloss. The task becomes recalling which word carries that meaning, with the letters as a prompt rather than the puzzle. You can override it and print plain scrambles if you want, but the default reflects what an advanced class actually needs.
Below C1 the definition format is unavailable, because definitions have not been written for those sets yet. The button is disabled rather than hidden, so you can see what exists and what does not.
For teachers
The most common use is the least glamorous: it is Sunday evening, you have Monday's vocabulary list, and you need something on paper. Paste the list, build, print two versions, done in about ninety seconds.
Two things worth knowing before you print. Keep a list to twelve words or fewer — beyond that the activity takes more class time than it earns. And avoid mixing three-letter and ten-letter words on one sheet, because the finishing times spread out badly and half the room ends up waiting.
If you would rather not build anything, the worksheet library has ready-made sets with classroom procedures attached. The ESL sheets cover new vocabulary, the beginner sheets suit learners still working on the alphabet, and the revision sheets are for sets you taught weeks ago.
Questions
Is it free?
Yes. No sign-up, no account, no limit on how many sheets you build. Nothing you paste is stored or sent anywhere — the whole tool runs in your browser.
Can I use my own wordlist?
Yes, and for most teachers that is the point. Paste words one per line or separated by commas. Your list replaces the built-in sets entirely.
Why did my scramble come out looking similar to the word?
Short words have few possible arrangements. A three-letter word has only five alternatives to itself, and if some of those spell other valid words, the remaining choices are limited.
Why does the format change when I pick C1 or C2?
Because a plain scramble stops teaching much by that level. Advanced learners recognise written words easily, so the sheet switches to printing a definition beside each scramble and the task becomes recalling the word that fits the meaning. You can switch it back to plain if you prefer.
Can I make several sheets at once?
Not in one click yet. Build, print, change the topic, build again. For a full set of six themed sheets the library is faster.
Does it work on a phone?
The tool does. Printing from a phone is possible but awkward, so build on a computer if you are producing sheets for a class.
