Alibi
Put every suspect and weapon back in the right room, and the killer reveals itself.
Every day: One murder case a day, the same for everyone: place every suspect and implement in the right room from true statements, with difficulty rising from Monday to Sunday. New puzzle: Midnight Eastern Time, as the game's page states.
Alibi is a daily deduction puzzle from Knotwise Games in the tradition of the Inspector Parker casebooks. Each case gives you a small house, a few suspects, a few implements and a list of true statements about where they were. Place them all correctly and the room holding both the killer and the weapon marks itself.
About Alibi
Alibi is a murder mystery you solve by placement rather than accusation. Someone died overnight in a house; the case file gives the household's statements, a small cast of suspects, a handful of implements and a set of rooms on a three by four board. You put every person and object where the statements say they must have been, and the room holding both a suspect and the weapon names the killer. The game is written by Shawn Liu of Knotwise Games and launched in May 2026.
Every statement is true, and every one is needed. Cases are generated backwards from a chosen answer: the generator collects every true statement, keeps those that narrow the case fastest until only one arrangement survives, then strips out any clue that is not strictly needed. A case that turns out ambiguous is thrown away. Daily cases also never include a clue that simply places someone in a room, so every placement is one you derive.
A new case lands at midnight Eastern. Difficulty follows a weekly ladder, open-and-shut on Monday and hard on Sunday. There are no lives and no fail state: a wrong placement just does not lock. The last seven days are free in the archive, and older cases come with a subscription. Today's case needs no account.
It suits fans of logic grids and Murdle who want a mystery with no guessing and no wasted words, and anyone who likes the moment a single forced placement makes the rest fall into place.
How to play Alibi
- Open Alibi and read the case: suspects, implements, rooms and statements.
- Find the person or implement with the fewest possible rooms and place it first.
- Use clues that rule rooms out as well as those that rule them in.
- Keep placing until every suspect and implement is in a room.
- The room holding both the killer and the weapon marks itself; that closes the case.
Tips
- Do not hunt for the killer; solve the arrangement and the accusation follows.
- Commit placements you are sure of, since each one makes the next inference visible.
- If two clues seem to clash, one of your placements is wrong; the statements never lie.
- Start with Monday cases in the archive to learn the clue wording.
Questions
When is a new Alibi case published?
Every day at midnight Eastern Time.
Can I lose?
No. There are no lives; a wrong placement simply does not lock. Mistakes and hints only decide whether your solve was flawless.
Do I need an account?
No. Today's case is free without signing in. An account syncs progress and, with a subscription, unlocks cases older than a week.
Could a case have two answers?
No. A case is only published once exactly one arrangement fits every statement.
