Frequently Asked Questions
Do I need an account?
No. Hangman runs straight from this page — no account, no sign-up, nothing to install. If you add your class names, they are saved in your own browser and never sent to Cloodit.
How do I play it with my class?
Put the page on your whiteboard or projector and press Play. The class calls out letters and you click or type them. Six wrong letters and the word gets away. After every word its definition appears, so each round ends on the meaning, not just the spelling.
Can I use my own words?
Yes. The free Hangman generator at cloodit.com/hangman/ takes any list: one word or phrase per line, with a definition after a dash if you want it shown at the end of the round.
Can I put my students' names in?
Yes. Add your class list and a random student is called for each word. The list stays in this browser on this computer, so it is still there next lesson.
What year level is this for?
Built for Year 7, and suitable for lower secondary generally — the modules investigate real issues (AI energy use, privacy, eWaste, how data is stored) at that level.
Is this aligned to a curriculum?
The journey is set for Year 7 under the Victorian F–10 Digital Technologies curriculum and uses the RADCAB method for judging sources, but individual modules aren't mapped to curriculum codes.
Are the worksheets free too?
Yes. Every module in this journey has a free printable worksheet with a full answer key, and there are crosswords and word searches built from the same key terms.
