Alibi

Project intro

Alibi is a party bluffing game for 3-8 players where an AI detective interrogates your friends. The lights went out, something vanished, and one of you is guilty — only the culprit knows it. A Gemini-powered detective writes a fresh case file, grills every suspect with pointed questions, flags the contradictions, and then the table votes: can the culprit bluff their way out? Play runs in five steps: get a case file with a random setting, crime, rooms, timeline and evidence; read your secret file in the dark by dragging a torch beam over it so nobody else can peek (the culprit gets a bluff idea, innocents learn their room, often with a partner who can vouch, plus a clue); interrogation over 1-3 rounds with one question per suspect per round, answered out loud and typed in; the detective's notes, with contradictions and a suspicion meter after each round; then a secret vote and a dramatic reveal that quotes the culprit's actual answer back as the tell. It supports pass-and-play on one phone or online rooms where everyone plays on their own phone with a 4-letter room code, is family-friendly by default, works on phones in portrait, and falls back to offline case files if the AI is busy so the game never stalls. Honest caveat from the author: the game server runs on a free plan and naps when idle, so the first load can take up to a minute to wake up ('Waking up the precinct…'), while pass-and-play works right away.
