A practical host helper
The roulette gives you a category, difficulty tag, and a short prompt for starting a question. It does not generate trivia questions or verify answers.
Local category list
Categories stay in this browser page and are never uploaded. Add, remove, or reorder lines whenever you like; blank lines are ignored when spinning.
Fair selection
Each spin uses the browser’s Web Crypto random source when available, with a browser pseudorandom fallback for ordinary game hosting.
GOOD TO KNOW
Common questions
Does this create trivia questions?
No. It chooses a category and difficulty tag, then gives a quick host prompt so you can ask or supply the question yourself.
Can I use custom categories?
Yes. Enter one category per line. Empty lines are ignored, and up to 100 categories are included in a spin.
Is my category list uploaded?
No. The list, result, and history stay in this browser tab.
