A new murder. Every day. Narrated. One answer. CASEFILE DAILY is a daily logic-deduction puzzle game set in 1940s noir. Every morning, a fresh case arrives. Your hardboiled detective reads it to you โ€” twelve seconds of rain, smoke, and motive. Then the grid appears. Mark what cannot be. Confirm what must be. When the logic holds, the case is closed. Come back tomorrow. โ€” โ€” โ€” WHAT SETS IT APART Voice. Every case is narrated by a hardboiled detective voice โ€” pre-recorded, not generated on your phone. Twelve seconds of atmosphere before the grid appears. This is not a silent puzzle. One correct answer. Every puzzle in Casefile Daily has been verified to have exactly one valid solution. If you follow the logic, you cannot be wrong by accident. There is no guess. There is no luck. Daily ritual. One new case every day. Five minutes. Then it's gone until tomorrow. The same case lands at midnight UTC for every player on earth. No subscriptions. Ever. Two optional one-time unlocks if you want to support the work. That is all. โ€” โ€” โ€” HOW TO PLAY Open the app. Today's case loads automatically. Listen to the narration โ€” or read the transcript if you prefer silence. Six to eight clues appear below the grid. Each one narrows the truth. Tap once to mark a cell impossible. Tap again to confirm. When every row and column locks into one answer, the case closes. Share your streak. Your friends see how you solved it, not the solution. โ€” โ€” โ€” FREE, ALWAYS Today's case is always free. Full detective voice narration with subtitles. Daily streak tracking. Share grid โ€” show your solve without spoiling the answer. Full accessibility: VoiceOver, color-blind mode, reduce-motion toggle. โ€” โ€” โ€” OPTIONAL ONE-TIME UNLOCKS $2.99 โ€” Remove Ads Forever. No interstitials, no interruptions. Yours permanently, including on reinstalls. $4.99 โ€” Unlock the Case Archive. Replay any past case from the full catalog. Today's case is always free regardless. No subscriptions. No recurring charges. No energy systems. Restore both purchases on any device, any time. โ€” โ€” โ€” ADS: WHERE THEY ARE (AND ARE NOT) Ads appear after a case closes, before the share screen. Never during play. Never on cold open. The noir atmosphere is never broken by a banner. โ€” โ€” โ€” ACCESSIBILITY VoiceOver: full support across all screens. Color-blind mode: replaces red/green grid marks with patterns. Subtitles: on by default for all narration. Reduce motion: disables smoke, rain, and reveal animations. Narrator volume: separate from music and system audio. โ€” โ€” โ€” BUILT SOLO Casefile Daily is made by one person at Culi Studio, evenings and weekends. Questions: support@culi.app. I write back. โ€” โ€” โ€” PRIVACY The narration was generated before the app shipped and lives on your device. Nothing about you is sent to any AI service at runtime.
