Casefile Daily is a daily logic mystery that arrives at your phone every midnight. You listen to a hardboiled detective narrate a twelve-second case, then solve it on a deduction grid using pure logic—no guessing, no multiple paths to victory. One puzzle, one correct answer, five minutes. It's a small ritual designed to close the case and move on. Let's walk through what happens from first open to your first solved whodunit.
Step 1: Launch and Listen to the Case
When you open Casefile Daily for the first time, you'll see today's case waiting. The interface is clean: a case number, a noir photograph, and a play button. Tap it. A hardboiled detective voice kicks in with a twelve-second narrative—recorded, not generated—that sets the scene. You hear the who, what, when, where, and why in just enough detail to solve the mystery. The narration is atmospheric; it hooks you before you ever touch the grid.

Step 2: Study the Deduction Grid
Once the narration ends, the deduction grid appears. You see a table with suspects, locations, weapons, and motives across the rows and columns. Your job is to cross out the impossible combinations and mark the truth. Each clue from the detective's narration maps onto this grid. Follow the logic strictly: if Person A was at Location B, then Person A cannot be at Location C. If the murder weapon was a knife, it wasn't a gun. Mark what you know for certain, eliminate what you've proven false, and the answer emerges naturally.

One correct answer, no guessing, no branching paths—follow the logic and you cannot be wrong by accident.
Step 3: Mark Your Final Answer
When you've eliminated enough impossibilities, one solution remains. The grid design makes it obvious when you're ready: the answer presents itself. Tap the final combination—who committed the murder, with what weapon, at which location, and why. The app verifies your logic instantly. Every puzzle ships with exactly one valid solution, verified before it goes live. You cannot accidentally stumble onto the right answer; you must follow the deduction path.
Step 4: Share Your Streak (Without Spoilers)
Once you solve the case, you unlock a shareable streak card. It shows your consecutive days solved, the case number, and the date—but nothing about the answer itself. You can post it to social media, text it to friends, or just keep it private. The design respects the mystery; nobody sees the whodunit unless they solve it themselves. This turns the daily ritual into a gentle social moment: comparison without spoiling.
Step 5: Explore the Archive (Optional)
Every case that lands on your phone stays in the app. Bundled cases ship with the app at launch; a new mystery drops daily at midnight UTC for all players worldwide. If you want to replay past cases or revisit ones you missed, the archive is there. A one-time unlock removes ads and opens full access to every case that's ever shipped, letting you work backward through the detective's case files at your own pace. Or just stick to the daily ritual and never look back. Both approaches work.

No Subscription, No Tricks
Casefile Daily is free to download and play daily. Ads appear between cases, but they're not aggressive. Two optional one-time purchases exist: remove ads forever, or unlock the full archive immediately. That's it. No battle pass, no energy system, no paywalls between you and the daily mystery. The game respects your time and your wallet. If you want to learn more about how noir narration and pure logic combine in this game, check out how Casefile Daily solves a murder every day.
