Why a quiz game works for studying

Teachers and students who want an online quiz game usually need the questions to match what was actually taught, which is the hard part to write by hand. A quiz built from your own lecture slides or reading handout keeps the focus on the material your exam will test.

  • Generate a fresh set of questions from any PDF, slide deck or set of notes.
  • Use multiple-choice, true/false or short-answer formats in a single quiz.
  • Read an explanation for every answer, right or wrong.
  • Export to PDF or DOCX for printing, or to QTI and Moodle XML on the Pro plan.
Example game-based learning quiz questions
What is game-based learning?Learning that uses game elements such as goals, points and immediate feedback to motivate practice. The game structure keeps learners answering and checking their answers.
Why does immediate feedback matter in a quiz game?It lets learners correct a wrong answer right away, before the mistake is practiced and remembered. Delayed feedback gives the error more time to stick.
What is a distractor in a multiple-choice question?A wrong answer option written to look plausible. Good distractors reflect common misconceptions, so they reveal what the learner still needs to understand.
What is the difference between a formative and a summative quiz?A formative quiz checks understanding during learning and usually does not count toward a grade. A summative quiz evaluates learning at the end of a unit.
Why can a leaderboard discourage some learners?It ranks students against each other, so learners far behind can lose motivation. Showing individual progress over time often keeps more students engaged.

Questions from your material

Multiple-choice, true/false and short-answer questions are written from the pages you upload, so the quiz covers your course rather than a generic question bank.

Explanations on every answer

Each question comes with an explanation of why the correct answer is right, so a wrong guess becomes a lesson instead of a dead end.

Flashcards and mind maps too

The same material can also become spaced repetition flashcards or a mind map, so one upload supports several ways of studying the topic.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a page. Photos are read with text recognition.

Choose the question types

Pick multiple-choice, true/false or short-answer questions, then generate the quiz.

Play the quiz and review

Answer in the browser, read the explanations, and retry the questions you missed.

Game formats help because they make retrieval practice feel quick and low stakes. Answering from memory, then checking the explanation, tends to build recall better than rereading the same notes. DeckOwl gives you the question set; you decide how often and in what order to work through it.

Frequently asked questions

Does a quiz game help you remember more than rereading notes?

Research on retrieval practice suggests that answering questions from memory usually improves recall more than rereading. A quiz game format can make that practice happen more often, which is the main benefit.

How often should I play a quiz to study a new topic?

Several short sessions spread across a few days usually work better than one long session. Revisiting the questions you missed after a day or two helps them stick.

Can I export my quiz to use in Moodle?

Moodle XML and QTI 2.1 export are on the Pro plan at $14.99 per month. PDF and DOCX export are included in Plus, which costs $99.90 per year or $9.99 per month.

Do I need a credit card to try it?

No. The free plan includes 3 generations per month and studying in the browser, and students get 40% off with a school email.
