A new mystery every morning
One murder.
One solution.
Can you close the case?
The Daily Case Files is a daily detective puzzle. Every morning brings a fresh murder, a short list of clues, and one — and only one — answer that fits them all. No luck. No guessing. Just deduction.
Free to play — no account needed.
A whodunit you actually solve
Each case lays out a cast: a handful of suspects, and the weapons, places, and motives in play. Your clues tell you what’s true and what isn’t — “the killer didn’t use the candlestick,” “the guest in the library came alone.” Cross off what can’t be, confirm what must be, and the truth is the last story left standing. Every solution is computer-verified, so there’s always exactly one answer, and it’s always findable from the clues alone.
How it works
Short, exact statements about who did — and didn’t — do what.
Tap cells to mark ✓ or ✗ and let the deductions cascade.
One suspect, one weapon, one place. Close the case.
Every case is part of a bigger mystery
Behind the daily murders runs a month-long story: The Ravenwood Masquerade. A masked killer hides among tens of thousands of possible disguises. Each daily case you close leaks one more clue about what they wore — a mask ruled out here, a colour there — narrowing the field day by day until a single disguise remains. Follow it all month, and the full reveal lands in the case file at month’s end.
