Murdle: Free Daily Murder Mystery Logic Game
A murder has been committed — and only pure deduction can crack the case. Read the numbered clues, fill in the logic grid, and accuse the right suspect: who did it, with what weapon, where, and why. Every case is generated fresh with exactly one solution.
What is Murdle?
Murdle is a murder-mystery logic puzzle. Instead of Sudoku digits you place suspects, weapons, locations and motives into a deduction grid until only one combination explains every numbered clue — then you name the killer. It's pure step-by-step deduction: no guessing required, ever.
How the deduction works
Every suspect is paired with exactly one weapon, one location and (on harder cases) one motive. The killer is one specific suspect, and the clues always tell the truth. Mark each grid cell ✓ (this pairing is true) or ✗ (this pairing is false). Because each category is a one-to-one match, every ✓ eliminates the rest of its row and column. When every row and column holds exactly one ✓ and the marks agree with all clues, the case is cracked — pick the killer and press Solve the Case.
How to play
- Read every clue before touching the grid — the last one often unlocks the first.
- Mark ✓ for a confirmed pairing; the rest of that row and column auto-fills with ✗.
- Use the suspects' public profiles: height and dominant hand resolve the killer clues.
- Watch clue 1's consequences ripple: every new ✓ or ✗ re-reads the whole clue list.
- When all grids are complete, tap a suspect to accuse them and solve the case.
- Daily Case gives everyone the same puzzle each day; Practice generates unlimited fresh cases in four difficulties.
Strategy tips
- Start with clues about the killer — handedness and height cut the roster immediately.
- An ✗ is information too: a full row of ✗ forces the one remaining cell to ✓.
- 'Either/or' clues cover two cells at once — test both branches against the grid.
- If your marks ever contradict a clue, undo instead of guessing around it.
- On harder difficulties, work weapon–location links first; they anchor everything else.
Murdle terms you need
- Deduction grid:
- The set of cross-tables linking every pair of categories — suspects × weapons, suspects × locations, and so on.
- The killer:
- The one guilty suspect. Clues that mention the killer constrain who the murderer can be.
- Pairing:
- A ✓ mark: the suspect and the item share the same slot in the solution.
- Elimination:
- A ✗ mark: the pairing is impossible. A complete row of ✗ forces the last cell.
- Either/or clue:
- A clue giving two options — one of the two pairings is true, the other is not.
- Daily Case:
- One shared puzzle per day, identical for every player worldwide.
Murdle vs Murdoku
Both hide a murder inside a logic puzzle, but they ask different questions — and both have official originals worth playing.
- Murdle is a category-matching deduction puzzle: pair suspects with weapons, locations and motives until one combination survives. The original daily game by G. T. Karber lives at murdle.com.
- Murdoku keeps the spatial Sudoku constraint — one suspect per row and column of a crime-scene map — and asks where everyone was standing. The original by Manuel Garand lives at murdoku.com.
- If you like elimination tables and 'which weapon' questions, stay with Murdle. If you like floor plans and 'who was in the room' questions, try Murdoku.
- This site generates its own original cases in both styles — nothing here is copied from the official books or sites.
Frequently Asked Questions
Have another question? Let us know.
Is Murdle free to play here?
Yes. Every case on this page is free, unlimited, and generated in your browser — no download and no account.
Is this the official Murdle game?
No. This is an unofficial, fan-made practice version with original cases. The official Murdle by G. T. Karber is at murdle.com, with a new daily puzzle and printed books.
How many suspects are in a case?
Between 3 and 6 depending on difficulty. Easy cases have 3 suspects and no motive category; Expert goes up to 6 suspects with motives.
Is there a new puzzle every day?
Yes — the Daily Case is identical for every player worldwide and refreshes at midnight UTC. Practice mode generates unlimited cases anytime.
Is every puzzle guaranteed to have one solution?
Yes. The generator verifies with a solver that exactly one complete assignment — killer, weapons, locations, motives — satisfies all the clues.
Do I need to guess or brute-force?
No. Every case is solvable by pure elimination: clues, ✓/✗ marks, and the one-to-one rule of each category. If you feel stuck, re-read the killer clues against the public height and handedness profiles.
What do height and handedness mean on the suspect cards?
They are public knowledge, not secrets. Clues like 'the killer is left-handed' or 'the killer is taller than another suspect' combine with the profiles to narrow the accusation.
Can I play on mobile?
Yes. The grids, roster and clues reflow for small screens — tap a cell to mark ✓, tap again to clear it.
