Auto lock-in
Choosing a multiple-choice answer submits it straight away — fastest, but there is no changing your mind. Grid-ins still need Enter or the button.

How scoring works
- Correct answer
- The bulk of every round.
- Speed bonus
- Scales with how much of the timer is left. Zero in untimed matches.
- First correct
- Only the first player to answer correctly gets it.
- Streak of 3+
- Applies while you keep answering correctly in a row.
- Wrong or unanswered
- No penalty — a guess costs you nothing but time.
Answers are graded on the server. Your browser never sees the correct answer until the round is over for both players.
