      The BT Dojo — classroom quiz duel

      A head-to-head quiz game built for the interactive whiteboard. Two students race to find the correct answer on their own board; the winner stays on as champion and a new challenger steps up. Lives, powerups and a class leaderboard keep the whole room in it — and you can load any question set you like: maths, spelling, science, vocabulary, history, anything.

      How to use it, who it's for & FAQ

      How to use it

      1. Pick a question set — use a built-in one or make your own in the editor (one line per question: question | answer | wrong, wrong).
      2. Type the first two students' names and press “Begin duel”.
      3. Both players race to tap the correct answer on their own board. A wrong tap costs a life; run out and you forfeit.
      4. The winner stays on as champion; enter the next challenger's name and play on. Check the leaderboard any time to rank the class.

      Who it's for

      • Teachers: a fast, high-energy starter or plenary for the whiteboard — on any topic, with the whole class cheering the duel.
      • Tutors & clubs: quick-fire recall practice with a bit of friendly competition and powerups to keep it fun.
      • Anyone: a two-player quiz duel for revision, family quiz night or a team ice-breaker.

      FAQ

      Is it just for maths?

      No — it works for any subject. It ships with maths sets (times tables, fractions, BIDMAS…) plus a capital-cities example, and you can add your own set on any topic in the editor.

      How do I make my own question set?

      Open the editor and type one question per line as question | answer | wrong answers. Wrong answers are optional — the board fills the rest from the other answers in your set. You can also import a set as JSON.

      Can it show maths properly?

      Yes — a light markup renders fractions (\frac{3}{4}), powers (x^2), roots and symbols like \times and \div, with no plugins to install.

      What are the powerups?

      Each round a player can use a Smoke bomb (removes four wrong answers from their own board), Heal (restores a life), and sometimes Block (freezes the opponent's board for three seconds).

      How does ranking work?

      The champion builds a streak by staying on, and every student's wins and best streak are tracked in a leaderboard you can display at the end of the session.

      Is it free and private?

      Completely — no ads, no sign-up, and your question sets and leaderboard stay in your browser. It works offline once loaded.
