Alibi Beta
Crack tonight’s case
A new murder-mystery logic puzzle every day. Work the clues, mark up the grid, and name the culprit — no spoilers, no signup.
A new puzzle unlocks daily at local midnight on your device — no account, no signup, and nothing to install. Progress and stats are saved locally in your browser, not on a server.
How to play
- The case intro tells you the murder weapon and room outright — those aren't secret. What's secret is which suspect's own alibi actually leads there.
- Every suspect has a real weapon and a real room. Work through the clues to reconstruct who had what, and who was where.
- Every clue is true. Use the notes grids to mark a pairing as ruled out or confirmed — click a cell to cycle through unmarked, ruled out, and confirmed. Confirming one automatically rules out the rest of that row and column. This is just for your own working; nothing is checked until you accuse.
- Once you're confident, pick the suspect whose weapon and room match the case, then submit your accusation.
- You have 3 accusations before the case goes cold and the culprit is revealed.

About Alibi
Alibi's a nod to my love of murder mysteries. Each night there's a new case - a set of suspects, a handful of clues, and you work through the logic to mark up the grid and name the culprit. No guessing needed - the clues always give you enough to get there for certain.
It's still the newest puzzle here and I'm actively tweaking it, so you might see some changes as I go.
Alibi FAQ
Is there always a unique solution?
Yes — every clue given is true, and each case has exactly one suspect whose weapon and room match. If two suspects still look possible, there's a clue you haven't applied yet, not an ambiguous case.
How many accusations do I get?
Three. The notes grid itself doesn't check anything as you fill it in, so you can mark up pairings freely and only spend an accusation once you're confident.
What do the ruled out / confirmed marks in the grid do?
They're just your own working — a way to mark a suspect/weapon or suspect/room pairing as ruled out or confirmed as you reason through the clues. Confirming one automatically rules out the rest of that row and column for you.
Why is Alibi marked as Beta?
It's the newest puzzle here, and I'm still tuning things like clue difficulty and case variety, so expect some changes as I keep improving it.
Do I need experience with logic puzzles to play?
No — every case is solvable through step-by-step deduction from the clues given alone, no outside knowledge or guessing required.
