What is Casefile Daily?

Casefile Daily is an iOS app that delivers one new murder mystery every day, narrated in twelve seconds of hardboiled noir voiceover and solved on a logic deduction grid. Each case has exactly one verified correct answer, the ritual takes about five minutes, there's no subscription, and you can share your solve streak without revealing the answer.

How does Casefile Daily actually work

You open the app, listen to a short noir-narrated setup of the day's murder, then move to a deduction grid where you mark clues against suspects, weapons, or locations until the logic points to one answer. There's no guessing mechanic hidden in the design — every case is built and checked so that following the clues correctly leads to exactly one valid solution, and there's only one path through the puzzle. For a deeper walkthrough of the mechanics, this FAQ on how the app actually works covers the grid logic in more detail.

Is Casefile Daily free to play

Yes, the core daily case is free with no subscription attached, and the app makes money instead through optional one-time unlocks. One unlock removes ads, and a separate one opens the full case archive if you want to replay past murders instead of waiting for midnight UTC. Nothing is metered or paywalled behind a recurring fee, so the daily ritual stays free indefinitely.

Can you actually get a Casefile Daily puzzle wrong by accident

No — every case ships with exactly one verified valid solution, so a wrong answer means a step in the logic was missed, not that the puzzle was ambiguous or unfair. This is a deliberate design choice: the studio checks each case to make sure there's no second reading of the clues that also fits, which means a wrong guess is always traceable back to a clue you overlooked rather than bad luck.

Do you need internet or a subscription to play

You don't need a live connection to solve the day's case once it's downloaded, and you never need a subscription at all. The narration is pre-recorded studio audio with subtitles rather than something generated on your phone at runtime, so what you hear is consistent voice acting, not a synthetic read. New cases still drop daily at midnight UTC for everyone at the same time, which is the one thing that does depend on the calendar rather than your connection.

What happens if you miss a day

If you miss a day, that specific case is gone from the free daily rotation, but it isn't gone forever if you've unlocked the case archive. The archive unlock lets you replay every past case at your own pace, which is the intended way to catch up after a busy week or revisit an old favorite. Without that unlock, the daily case is a one-shot ritual tied to that specific day.

How do you share your streak without spoiling the case

Casefile Daily's share feature posts your streak and solve status without printing the suspect, weapon, or motive anywhere in the shared text, so friends see that you closed the case without seeing how you closed it. This mirrors the spoiler-safe sharing style people expect from daily word and number puzzles, adapted for a mystery where the actual solution is the thing worth protecting. It's built for the same reason people compare streaks in other daily habit apps: the ritual is social, the answer isn't.

Common questions

Is Casefile Daily the same murder for everyone?

Yes, every player worldwide gets the same case on the same day, since new cases drop at midnight UTC rather than on a per-user schedule. That's part of what makes streak-sharing meaningful — you and a friend are solving the exact same mystery, not different randomized versions.

How long does one case take to solve?

Most cases are designed as a five-minute ritual: about twelve seconds of narration followed by working through the deduction grid. It's built to fit into a coffee break or commute rather than a long puzzle session.

Does Casefile Daily use AI-generated voices?

No, the narration is pre-recorded hardboiled detective voice acting with subtitles, not audio generated on your phone at runtime. The atmosphere comes first, before you ever touch the grid.

What do the one-time unlocks include?

There are two separate one-time unlocks: one removes ads, and the other opens the case archive so you can replay every past case. Neither is a subscription, and the daily case itself stays free regardless of whether you buy either.

Can two different clue readings both be correct?

No, every case is verified to have exactly one valid solution before it ships, so there's no case where two different suspect combinations both technically fit the clues. If your answer is wrong, a clue was missed rather than misread ambiguously.

Is there a tutorial for the deduction grid?

Yes, the onboarding walks through listening to a case and then marking the grid step by step before your first real mystery. It's a short, one-time setup rather than a recurring tutorial.
