Duel — Bash KO Hub

Sign in first

This duel uses your Bash KO Hub account to know who you are. Open the hub, sign in, then come back here.

No live session

Start a session, tick the students who are taking part, and the server will draw random pairs and random questions. Students press Ready on their own devices; you start each pair when both are ready. Several duels can run at once, and students may participate in more than one session.

How the live duel works

You select participants and confirm. Pairs and questions are drawn randomly on the server — students see nothing until it is their turn.
Each student opens this page on their own device and presses Ready. Start a pair once both players are ready.
Players alternate: 10 questions each, 30 seconds per question. The clock starts when the question reaches the student's screen.
Tied after the last round? Each player gets one more question, repeated until someone leads (up to 20 extra rounds; if still level after that, the match is recorded as a draw — you can also abort a long tie-break at any time).
Every finished match is saved to the cloud and appears in View All Results / Export CSV.
Mad Duel plays a schedule: choose the participants once and the server draws 100 rounds of pairs for the months ahead, each round on one unit it keeps to itself. Students see nothing of it; you see the pairs; only Bash sees the units. Over the whole schedule no student meets a question twice (tie-breaks aside), and every question a student meets moves a rating that only Bash sees.
