A sure-sounding witness testifies to every trivia question, but it lies sometimes, and catching the lie pays the most.
Each round a witness states an answer to a trivia question with total confidence. You decide whether to trust the testimony or challenge it as a lie. Trust a true answer for small points; catch a lie and name the real answer for the big score. Guess wrong either way and you lose points.
Deciding whether a confidently delivered answer is true is the panel-game tradition of Call My Bluff and Balderdash, where the entertainment is in the telling rather than the fact.
The original framing is the courtroom, and the asymmetric scoring: trusting a true answer pays little, catching a lie and supplying the real answer pays a lot.
That scoring is what makes it a game rather than a quiz. A pure trivia round rewards knowing; this rewards doubting correctly, so a player who knows less but reads people better can win — and the expensive mistake is trusting something you could have challenged.
Witness Stand is an original free browser trivia game that wraps a quiz in a courtroom of deception, rewarding you for reading a confident liar as much as for knowing the facts.
