Three free daily murder mystery games are worth your morning in 2026: Murdle, Mystery-o-matic, and Daily Detective. Daily Holmes belongs in the rotation when the case is a crime scene, which is one format of fifteen.
That is the short answer. The longer one is this page: every daily murder puzzle we could find, loaded and checked in August 2026, described plainly, including the one we make. Sites that would not load were left out. In a niche this small, that rule alone shortens the list.
The daily murder, defined
A daily murder mystery game gives everyone the same crime on the same day, solvable in minutes, with a fresh one at midnight. The format descends from Wordle, but the genre splits into two families. In the first, the murder is a costume worn by a logic puzzle: suspects, weapons, and locations are stipulated, and you eliminate combinations until one remains. In the second, you are shown evidence and asked what it proves. Both families are represented below, and they exercise different muscles.
The games, one by one
Murdle
What it is: A daily logic-grid murder mystery, published every day since 2022 by G. T. Karber. A short narrative introduces the suspects, weapons, and locations; you cross-eliminate on a grid until the who, the how, the where, and the why lock into place.
Strength: Craft. Karber writes with a light, macabre wit, the puzzles are fair, and the daily has held for four years without missing a morning. The book series the site spawned became a bestseller and took the UK Christmas No. 1 spot in 2023, which tells you how sturdy the formula is. If the genre has a standard, this is it.
Limitation: The murder is a costume. Underneath sits pure constraint satisfaction, closer to Sudoku than to detection: nothing is observed, everything is stated. There is exactly one provable solution, found by elimination. Deeply satisfying, but a different skill from reading evidence in a scene.
Mystery-o-matic
What it is: A machine that commits a fresh murder every night. Each day the site generates a new case: suspects move between rooms on a timeline, their statements are truthful but never the whole story, and you must name the killer, the weapon, and the time of death. Open source, playable in English, Spanish, and Russian, and built to be solved in under five minutes. Its motto: a mystery a day keeps the coroner away.
Strength: The generator. Cases are produced by simulation, and the code is public, so the supply never runs out and the logic is airtight by construction. Its instructions state the genre's creed in one line: rule out every option but one, and the one that remains must be true.
Limitation: Generated stories have no author. Nobody planted a red herring for you personally, and motive is not on the board: you answer who, with what, and when, never why. The presentation is spare, closer to a proof than a story.
Daily Detective
What it is: A small browser game that calls itself a free daily murder mystery and logic puzzle site: a new noir-style whodunnit every 24 hours, solved with logic and deduction, in its own words.
Strength: It is exactly what the search asks for: a murder a day, free, in the browser, no ceremony and no account.
Limitation: The site is quiet about itself. There is no named creator and no visible history, and the game runs entirely inside the app, so we can report what it promises more than how it is made. It was live and free when we checked; beyond its own description, you are on your own.
Daily Holmes
What it is: One photograph of a stranger's space, published at midnight UTC, and a question. You read the scene, make your case in one of fifteen formats, and an AI examiner grades your reasoning, evidence first. Free. No signup to play today's case.
Strength: It is the only daily on this list where the evidence is visual. On crime-scene mornings you do the thing the other games abstract away: look at a room and decide what it proves. The grade rewards the chain of reasoning, not a single right answer, so a sharp wrong theory earns more than a lucky guess.
Limitation: Honesty requires the fine print: not every Daily Holmes case is a crime. The crime-scene format is one of fifteen, and most mornings the mystery is quieter, a kitchen or a coat rather than a body. If you want a murder every day without fail, Murdle and Mystery-o-matic keep that promise; we promise a scene worth reading every day, which is a different thing.
The nearest neighbor
One game sits just outside the definition and earns the mention. Clues by Sam, launched in May 2025 by Finnish developer Johannes Ahvenniemi, deals you a grid of twenty suspects and asks which of them are criminals. There is no body and no weapon, so it is not strictly a murder mystery, but the discipline is the purest in the field: every move must be a provable deduction, guessing is simply not allowed, and the puzzles climb from easy at the start of the week to genuinely cruel by the end. It is free, with optional paid puzzle packs. If the elimination half of these games is what you love, start there, then browse the wider field in our roundup of the best daily deduction games.
Which one should you play
They are complementary, not interchangeable. A quick sorting:
- For authored puzzle craft: Murdle. A writer built it, and it shows in every case.
- For speed and endless variety: Mystery-o-matic. Five minutes, airtight logic, a new crime from the machine every day.
- For a plain daily whodunnit: Daily Detective. No frills, no account, one murder every 24 hours.
- For reading a scene instead of a grid: Daily Holmes. The crime arrives as a photograph, and the work is observation before logic, the method we unpack in Visual Deduction 101 and The Science of Deduction.
Many players rotate: a grid for the logic, a photograph for the eye. The grids train elimination, the certainty that comes from ruling things out. The photographs train noticing, the habit of asking what a detail is doing there before deciding what it means. A month of both leaves you sharper than a month of either.
A note on the empty chairs
This list is shorter than the search results, and that is deliberate. Search for a murder mystery daily game and the results are mostly micro-sites, and micro-sites die quietly. At least one domain built on this exact phrase returned nothing but a server error when we checked in August 2026, so it is not here. We list what loads and describe what we can verify, nothing more. The daily format is a promise, one puzzle every single morning without exception, and keeping that promise is the hardest feature any of these games ship. The ones above are keeping it.

Play today's caseFrequently asked questions
Are there free daily murder mystery games?
Yes. Murdle, Mystery-o-matic, and Daily Detective each publish a free murder puzzle every day, playable in any browser with nothing to install. Daily Holmes is free too, with no signup to play today's case; its crime-scene photographs are one format among fifteen, so not every morning is a murder.
What is the best daily murder mystery puzzle?
Murdle, if one game must be named: four years of daily puzzles, an author with a voice, and a fair grid every morning. Mystery-o-matic is the pick for speed and endless generated variety, and Daily Holmes for mornings when you would rather read a photographed scene than fill in a grid.
How is Murdle different from Mystery-o-matic?
Murdle is authored: G. T. Karber writes each case, and the wit is part of the product. Mystery-o-matic is generated: software simulates the crime and derives the clues, which guarantees airtight logic and an endless supply, but no authorial voice. Murdle asks why the crime happened; Mystery-o-matic stops at who, with what, and when.
Does Daily Holmes publish a murder mystery every day?
No, and the distinction matters. Daily Holmes publishes one photographed case every midnight UTC, but the crime-scene format is one of fifteen. Many cases are quieter deductions about who lives in a space or what happened there. Play it for the reading of evidence, not for a guaranteed body.
How long does a daily murder mystery take?
Minutes, by design. Mystery-o-matic is built to be solved in under five. Murdle's daily case takes most players a similar sitting. Daily Holmes promises one photograph and three minutes. The daily format only works because the commitment stays small; the constraint is the charm.
