What is Casefile Daily?

Casefile Daily is an iPhone app that delivers one new murder mystery every day, narrated in twelve seconds of hardboiled detective voice and solved on a logic deduction grid. Each case has exactly one verified correct answer, takes about five minutes, requires no subscription, and lets you share your solved streak without revealing the answer.

If you've seen the noir detective with the fedora and the daily grid puzzle floating around and wondered what you're actually signing up for, this is the rundown. No hype, just the questions people type into search bars before they download Casefile Daily.

how does casefile daily work

You open the app, listen to a short pre-recorded narration setting up the day's murder, then fill in a deduction grid using the clues given in that narration and the case file. There's no random guessing rewarded here — the grid works like a classic logic puzzle, where each clue eliminates possibilities until one answer is the only one left standing. Subtitles run alongside the audio, so you can solve with sound off if you're on a train or next to someone sleeping.

is casefile daily free to play

Yes — Casefile Daily has no subscription and the daily case is free to play indefinitely. The app offers optional one-time unlocks that remove ads or open the full case archive, but neither is required to solve today's murder or keep your streak going.

does every case have one correct answer

Yes, every case is verified before it ships to have exactly one valid solution. That verification matters more than it sounds — it means if you follow the logic correctly, you will land on the right answer, and if you land on the wrong one, it's because a clue was missed or misread, not because the puzzle itself was ambiguous. That's a deliberate design choice that separates a deduction grid from a coin-flip trivia guess.

Follow the logic and you cannot be wrong by accident.

can you play old cases you missed

Yes, missed cases live in the archive and can be replayed anytime after you unlock it. This is one of the two optional one-time purchases in the app, alongside ad removal, and it means a busy week doesn't mean lost cases — they're waiting whenever you want to catch up.

when does the new daily case drop

A new case unlocks for every player at midnight UTC, so the puzzle is the same worldwide regardless of your local time zone. That shared timing is part of what makes streak-sharing work — when you post that you closed the case, friends across time zones know exactly which mystery you mean, without you spoiling the solution.

what happens if i miss a day in my streak

Missing a day resets the running streak count, but it doesn't lock you out of the mystery itself since that day's case simply moves into the archive for later replay. The streak is a personal counter you can choose to share, and the app is built so a broken streak costs you bragging rights, not access.

Step 1: Solve today's case in five minutes

Open the app, listen to the twelve-second narration (subtitles available), read the case file for clues, mark eliminations on the deduction grid, and submit your answer. Once you close the case, share your streak card — it shows your count, not the culprit.

Common questions

Do I need to play every day to understand the story?

No — each case is a self-contained murder with its own setup, clues, and solution, so you can jump in on any given day without prior context. There's no ongoing overarching plot you need to catch up on.

Is Casefile Daily generated by AI?

The detective narration is pre-recorded audio with subtitles, not generated live on your phone, and every case is verified ahead of time to have exactly one correct answer. That verification step is what keeps the puzzles fair rather than randomly assembled.

How long does one case take to solve?

Most people finish in around five minutes: about twelve seconds of narration followed by a few minutes working the deduction grid. It's designed as a short daily ritual, not a long session.

What do the one-time purchases actually unlock?

There are two optional one-time unlocks: removing ads, and opening the full case archive to replay past mysteries. Neither is a subscription, and neither is required to play the current day's case.

Can I play with the sound off?

Yes, subtitles accompany every narration, so you can read the case setup instead of listening to it. This makes it easy to solve on a commute or anywhere headphones aren't practical.

Does sharing my streak reveal the answer to friends?

No, the share feature is built specifically to show your streak count without exposing the day's solution. Friends can see you solved it without having the mystery spoiled for them.
