Case Zero: Daily Mystery

A new case every day. Case Zero is a daily detective deduction game. Read the evidence, place each suspect, and name the culprit before your attempts run out. A single case takes five to ten minutes. Open the app, solve it, close the app. Tomorrow brings a new one. YOUR DAILY CASE Every day, one new case unlocks at midnight UTC. Free to play. No login, no account, no ads. Solve it in your morning coffee or your evening commute. Share your result without spoilers, the way Wordle taught us. HOW YOU SOLVE Four puzzle styles rotate through the dossier: — LOGIC GRID. Four suspects, four rooms, four motives. Six clues. One thief. Eliminate the impossible. — TIMELINE. Five events, five witnesses, one liar. Reconstruct the order and find the lie. — CONTRADICTION. Four statements, three true, one impossible. Spot the inconsistency. — ALIBI WEB. Five suspects, mutual alibis, one unaccounted soul. Map the network and identify the gap. Every case is hand-curated. Every solution is unique. Every clue earns its place. SCORING Solve cleanly on your first try, in under two minutes, and your case-file rating earns three magnifiers. Take longer or stumble, and the rating drops. Daily streaks track consecutive solves. Miss a day and the streak resets — yes, like the others. WHAT'S FREE — Today's case, always, with full scoring and sharing. — Streak tracking. — Result cards you can copy and paste anywhere. WHAT THE DETECTIVE PASS UNLOCKS A single one-time purchase.
