Yes or No - 探偵ゲーム：究極のソーシャルミステリー体験

A friend witnessed something impossible. You’re at the scene. You can interrogate the witness… but they will answer ONLY with: “Yes”, “No”, or “Irrelevant”. That’s how Case Files begins — a detective party game of short mysteries you solve through questions, deduction, and teamwork. HOW TO PLAY 1. Pick a Host. 2. The Host chooses a case and reads the setup. 3. Everyone else asks yes/no questions to uncover the full story. 4. Connect clues, test theories, and crack the case. WHY YOU’LL LOVE IT • Feels like real detective work: motives, timelines, alibis, twists. • Plays in 5 minutes… or keeps the whole group hooked for hours. • No board, no table — perfect for parties, road trips, cafés, and walks. FEATURES • Mystery cases with clean, logical solutions (no supernatural hand-waving). • Categories & difficulty: from quick warm-ups to brain-melters. • Family-friendly cases plus more mature cases for grown-ups.
