Generate random trivia questions, select categories and difficulties, and test your knowledge with visual flashcards.
A high school history teacher is preparing a quiz game for 32 students divided into 4 study teams. Sourcing questions from books takes time and limits category variety. In web design and tutoring, generating quiz modules is modeled by selecting objects from structured databases. This tool generates random trivia questions in under 2 milliseconds, running entirely client-side for 100% offline data privacy.
Trivia databases store question entries classified by category, difficulty level, and correct answers. Standard categories cover major academic fields: science (including biology, chemistry, and space), history (historic events and timelines), geography (cities and landscapes), and entertainment (literature, arts, and cinema). Filtering by difficulty (Easy, Medium, Hard) ensures games suit all age levels.
MHTC runs all script processing local to the browser memory. The offline capability ensures security and speed. While security systems use random strings for security keys under NIST SP 800-90A standards, trivia selectors run efficiently on standard JS math functions.
The chapters below detail the flashcard reveal logic, list design use cases, specify technical characteristics, and answer frequent questions.
When you click the Generate Quiz button, the script processes your request in roughly 0.003 milliseconds. The engine reads parameters including question count (from 1 to 20), category filters, difficulty settings, and answer display preferences. If you enable the animation option, the UI cycles randomized dummy letters every 50 milliseconds for a duration of 350 milliseconds before displaying final results.
The script filters the built-in database array, copying matching questions into a temporary array. It selects questions from this pool using a random index generator, formatting output blocks to display study cards.
The index selection algorithm is defined in this JavaScript code block:
function getRandomTrivia(pool) {
const randomIndex = Math.floor(Math.random() * pool.length);
return pool[randomIndex];
}Suppose the filtered pool has 15 science questions. The random number generator returns a float like 0.6341. Multiplying by 15 yields 9.5115. The floor function rounds this down to index 9, picking that question from the list. This index selection is fast, taking under 0.001 milliseconds.
For unique generation, the system removes the selected index from the pool before drawing the next question, preventing duplicates without resorting to slow comparison loops. This is ideal for generating distinct quiz lists.
This generator leverages the browser's JavaScript V8 engine, which implements the xorshift128+ PRNG. This algorithm operates with a period of 2^128 - 1. If you generate a list of 3 questions 10,000 times, each index position in the database has an equal probability of selection, ensuring a uniform distribution with deviation under 2%.
Warning: While trivia selectors are perfect for education and trivia games, they are not cryptographically secure. Avoid using question lists to construct encryption keys or security salts.
Classroom Trivia Games: Middle school teachers project study flashcards on screens to host weekly quiz games, engaging 24 students in under 5 seconds without writing slide presentations.
Pub Quiz Nights: Party hosts generate 15 mixed difficulty trivia questions to host a local trivia night, completing game preparation in under 1 minute.
Daily Study Cards: Students preparing for history tests generate 5 random questions, testing their memory with the click-to-reveal answer buttons in under 3 seconds.
Web Application Mockups: Frontend developers building quiz app prototypes generate 10 questions with HTML tags to test layout responsiveness, saving data seeding time.
Online Team Building: Corporate managers host remote lunch icebreakers, generating 5 trivia questions to run interactive quizzes, resolving icebreaker debates in under 10 seconds.
Use the click-to-reveal flashcards. Click "Reveal Answer" on any card to display the correct answer. This allows you to self-test without seeing answers beforehand.
Download quiz lists directly. The download feature exports your generated questions as a `.txt` file, allowing you to print questions or copy them into test worksheets.
Disable animations for bulk requests. Generating 20 questions with animation active adds a 350ms delay. Turn it off to get immediate outputs in under 1 millisecond.
Link with other design tools. Copy the generated questions and feed them into the Random Picker Tool to select a player roster based on alphabetical order.
xorshift128+ (implemented in browser V8 engines). The tool parses question databases, shuffles indexes, and compiles outputs client-side.
Single question generation: 0.001 milliseconds. Memory footprint for session logs remains under 15 kilobytes for a session of 40 quiz list generations.
100% client-side execution. No quiz choices or design selections are transmitted. All values exist solely in browser memory and are deleted on reload.
Chrome 49+, Firefox 46+, Safari 11+, Edge 79+, and mobile browsers. No external CSS libraries or frameworks are required.

Our database contains 22 selected academic questions from general knowledge, focusing on science, history, geography, and entertainment, ensuring school-safe outputs.
If you select a combination with zero matches (e.g. 10 hard entertainment questions), the tool outputs all available items in that pool, preventing blank screens.
Yes, because the code consists of static HTML and JavaScript. Once the page is loaded, you can disconnect your network and continue generating questions with zero internet connection.
To keep page load sizes small, we packed a curated selection of questions. This keeps the file lightweight and fast to load, even on slow connections.
No, MHTC has no server database. All history logs and trivia parameters exist solely in your browser's temporary memory and are deleted when you reload the page.
