"Do you promise that your detectives shall well and truly detect the crimes presented to them using those wits which it may please you to bestow upon them and not placing reliance on nor making use of Divine Revelation, Feminine Intuition, Mumbo Jumbo, Jiggery-Pokery, Coincidence, or Act of God?"
The opposite of a Clueless Mystery
; the puzzle of the story is entirely solvable before The Reveal
or The Summation
, if you've spotted the clues, and not just by various methods
of being a Genre Savvy
reader/viewer. The trick, of course, is having it solvable by the reader/viewer, but still difficult enough that they don't all figure it out long before the actual reveal.
In 1928, the writer Father Ronald Knox created a "Ten Commandments" of plot devices (Knox's Decalogue
) that more or less codified the rules of the Fair-play whodunnit:
- The criminal must be someone mentioned in the early part of the story, but must not be anyone whose thoughts the reader has been allowed to follow.
- All supernatural or preternatural agencies are ruled out as a matter of course.
- Not more than one secret room or passage is allowable, and such a passage may only be in a house or building for which it is appropriate by age or purpose.
- No hitherto undiscovered poisons may be used, nor any appliance which will need a long scientific explanation at the end.
- No Chinaman must figure in the story.note .
- No accident must ever help the detective, nor must he ever have an unaccountable intuition which proves to be right.
- The detective must not himself commit the crime.
- The detective must not light on any clues which are not instantly produced for the inspection of the reader.
- The stupid friend of the detective, the "Watson", must not conceal any thoughts which pass through his mind; his intelligence must be slightly, but very slightly, below that of the average reader.
- Twin brothers, and doubles generally, must not appear unless we have been duly prepared for them.
Though increasingly rare in modern mystery literature and non-print media, in the "Golden Age" of mystery, novels were almost entirely of this type, though even then some were better about the "fair" part than others. This trend is kept alive largely through its incorporation in "Dinner Theater", where a short mystery play is acted out while the patrons eat, and the audience is invited to solve it before the answer is played out.
Done badly, this can lead to Conviction by Contradiction
. Done correctly, and it turns into what Golden Age writer John Dickson Carr
called "The Grandest Game in the World."

Anime and Manga
- Two manga, The Kindaichi Case Files and Detective Conan, based upon teenagers solving mysteries, give you the information to unveil the killer before the solution is officially "revealed" - Kindaichi much more so, because the translators go through more effort to translate the evidence to English, while to solve the Detective Conan mysteries, once in a while you'll need to know various Japanese references, names, and pronunciations.
- Unfortunately for Detective Conan, this doesn't translate to the anime, which feels free to hide the evidence from you. (Although, especially early, Funimation made more of an attempt to translate cultural-specific info than Viz does with the manga.)
- The anime is sometimes good about playing fair, and other times shamelessly cheats. It depends on the writer, though the show seems to cheat more nowadays than they did in earlier seasons. Any story based on the manga will still be fair play, though, unless something crucial is cut during the shift from manga to anime.
- The odd things about Detective Conan is how it follows the second rule: The whole Myth Arc is based on the protagonists being de-aged by poison, the devices he constantly uses are blatantly science fictional, and the show shares a setting with Magic Kaito where some of the events explicitly involve actual MAGIC. Yet none of the day-to-day cases involve factors that aren't possible in real-life.
- The Melancholy of Haruhi Suzumiya has the mystery episode "Remote Island Syndrome". The first part of the episode seems to be a regular fun-filled day on a private island. That episode secretly contains almost all the clues you need to solve the mystery presented in the second half, although if you don't expect the mystery, you could easily miss them.
- However, it's heavily implied that Haruhi, despite noticing the clues, never actually solved the crime — she changed the facts of the case to fit the clues.
- This case was significantly different in the original novels, with Kyon's sister not going on the trip, copious amounts of alcohol being involved, and none of the incidents which implied use of Haruhi's powers (such as her and Kyon going out in the storm and seeing the mysterious shadow). The later story of Snow Mountain Syndrome has Koizumi deliberately set up a similar event on the trip with a detailed script which has given to all the characters to see if they could deduce it. Haruhi and Tsuruya got it before the other characters, but enough clues are given that the reader can solve it even before them.
- Mike W. Barr's The Maze Agency series revolved around a beautiful ex-CIA agent who runs a PI firm, her true crime writer fiance, and the (usually fairly clued) mysteries they run across.
- A number of Batman comics, particularly during the Denny O'Neill/Neal Adams period in the '70s, provided fair-play mysteries. The narration would even challenge the reader at one point, once all the clues were presented to solve the crime before Batman.
- A slight example: In The Many Deaths of the Batman, Batman seemingly falls off a roof and into a river while chasing a crook, and his body is fished out of Gotham River. Observant readers will note that the first chase sequence clearly has the Eiffel Tower in the background. Sure enough, Batman's alive and well, just a bit damp.
- Roger Stern's run on Amazing Spider-Man had several hints as to the Hobgoblin's identity, such as that he was wealthy, upper-class, and was someone who was cunning and ruthless. Although it was revealed that the Hobgoblin did have an identical twin who posed as him whenever he was dressed as the Hobgoblin, there was one tiny hint to this in a single panel. So if someone had found this tiny hint, they likely could have worked out the Hobgoblin's identity, although with various changing writers, the whole thing soon became a confusing mess, which was only really fixed when Stern himself returned to write the Hobgoblin Lives! miniseries, over ten years after the Hobgoblin's first appearance.
- Subverted in the Tintin story The Castafiore Emerald. The eponymous emerald is stolen, and the book gives the reader various clues implicating several different suspects. In the end we find out the culprit is a thieving magpie. There is a very minor clue pointing towards the identity of the thief, so technically it's possible to guess who it is, but all the major clues are there just to play with the reader's expectations of this being a Fair Play Mystery.
- In My Little Pony Micro Series Issue #1 all the clues that Twilight picked up on revealing Jade's identity are shown to the reader prior to her explanation - though not explained at that time they are shown. A big clue is a smudged cutie mark. However, some of the clues required a priori knowledge of Jade Singer - like her glasses and love of swing music - which are only brought up in connection to her when Twilight explains them.
- Similarly, in the main comic #21-22 (the Trixie arc), the reader can figure out Rough Diamond's real identity within the first fifteen pages, and the clue that eventually convinces the protagonists is shown several times in good detail.
- Set up, but not revealed to be a mystery until the end of Transformers: More than Meets the Eye #18. The crew of the Lost Light are holed up in a jail cell with an Autobot named Minimus Ambus, a small-time Energon trader who was accused of smuggling dangerous superfuels, only it's heavily implied that's not the whole truth. The psychologist Rung has his suspicions as to what's going on, and finally calls out Ambus in front of the crew. He points out that careful observation of Ambus' behavior throughout the book revealed, among other things, meticulous focus on order and procedure, an utter lack of mirth, and an immense distaste for filth and mess, as well as various quirks of speech tone and vocal pattern. It's possible to spot the same things Rung did, and come to the same conclusion. Minimus Ambus is in fact Ultra Magnus, stripped of his Ultra Magnus armor and identity.
- Turnabout Storm has the protagonists and viewers share the same level of knowledge of the crime most of the time, which means the audience is given all clues necessary to uncover the truth as the case unravels. Before the final confrontation, all the information necessary to deduce the entirety of the events is given.
- The Last Of Sheila, where not only is the title a clue, but if you pay close attention during the early scenes you will see a vital clue that directly points to the murderer's identity.
- Played with in Deep Red; an early scene actually shows the face of the murderer, but it's done so quickly - and before you know to look for it - that most people never catch on.
- The Japanese film The Laughing Policeman plays with this trope. Many clues are given from the outset, but many are so subtle at first that the detectives don't notice them at all until towards the end. It also subverts this by having someone kill the Big Bad offscreen just as the cops plan to arrest him. This is only to reveal the real mastermind, the titular Laughing Policeman who never gets figured out.
- Hot Fuzz actually follows the rules rather well. The audience sees all of the clues Detective Angel sees, and his partner fits the 'below-average intelligence' requirement. The clues are so plentiful in pointing to a singular culprit, it almost seems like a Reverse Who Dunnit. Then it's all subverted. EVERYONE in town except for the children and a few police are guilty. Better still, the earlier clues could have legitimately indicated this.
- Agatha Christie was a member of the Detection Club, the members of which promised to write their stories like this. However, that didn't stop her from having the narrator lead the reader down the garden path to the wrong answer. For example: in "Hercule Poirot's Christmas", Poirot asks the butler what the date was three days ago; the butler walks over to a wall calendar and reads off 'the 22nd'; and the reader is led to conclude that there is something important about the date. However, during The Summation, Poirot says that the whole point was to find out if the butler had bad eyesight. She also plays fast and loose with the no doubles or hitherto unknown twins rules, by dropping two hitherto unknown illegitimate sons of the victim into the pot.
- Several of the Miss Marple short stories were the ultimate in fair play. They were told to Miss Marple by guests at a party, so the reader knows exactly what the detective knows. It also helps explain what an elderly woman is doing solving mysteries.
- The Mysterious Affair at Styles is absolutely a Fair Play Whodunit. The reader knows everything Poirot does. No unknown illegitimate children there.
- The Murder of Roger Ackroyd is also extremely fair. The way Poirot ultimately solves the crime is by reading what Dr. Sheppard wrote down which is exactly what the reader is reading. Which means that an acute reader could actually pick up most of the important clues before Poirot does.
- It does violate two of Knox's Commandments ( the First and the Ninth; the Watson of the novel is also the murderer, and he does not write down every thought he had in the journal). This does not keep it from being fair, serving as reminder that rigid adherence to Knox's rules is not what makes a good Fairplay Whodunnit.
- Michael Connelly's mystery novels are often these; The Poet actually won an award for Fair Play.
- Note: make sure you read this before reading its sequel The Narrows, which itself has a fair play Twist Ending.
- There's a Lord Peter Wimsey mystery where a particular missing item from a painter's setup is an important clue that the painter had been murdered, rather than died accidentally, and the page revealing what it is before The Summation, in a vaguely clever twist, is removed for "the entertainment of the reader".
- Sayers still plays fair, though. There are three or four other scenes between the missing page and the summation which, taken together, can be used to work out what the object was and what happened to it.
- In fact you can deduce what's missing in the same way that Lord Peter does, from the description of the scene alone, although a (very) basic knowledge of oil painting may be needed.
- Asubversion is Have His Carcase, where the solution requires on a very elaborate (and accidental on the part of the murderer) trick involving the time of death. The victim has a rare condition known as hemophilia, which prevents the blood from clotting, obscuring the real time of death. If the reader is knowledgeable enough in minor trivia, there are enough clues for a genius to figure out what the trick is - but it requires a very specialized knowledge base that most people simply do not have. For those without the prerequisite knowledge, Lord Peter's revelation seems a bit like an Ass Pull or Deus ex Machina, though the astute and Genre Savvy reader can generally figure out that something is hinky, because everyone's alibi is too solid, which is what tips Wimsey off that something is hinky. One of the things that tips him off to the identity of the murderer is that that suspect also has a (manufactured) alibi for the real time of death, once he realizes what that is.
- Most Sherlock Holmes mysteries are not really fair, if only because Dr. Watson (the narrator) is not as observant as his colleague, but "The Lion's Mane" gives the reader enough information to draw a conclusion even before Holmes does (although this may not have been Conan Doyle's intention).
- It bears mentioning that Watson is usually writing these up after the fact. He could give the reader the clues—Holmes himself professed a preference for a didactic style of write-up that would be something like this trope—but arguably intentionally averts the trope in order to play up Holmes's brilliance, as well as for the continuity of the narrative. If Watson's powers of observation had been greater, it might be true that his normal narrative flow might well play the trope straight.
- "The Lion's Mane" was one of the few stories narrated by Holmes himself, which could mean the difference was intentional after all.
- Silver Blaze is another. All the important clues are shown to the reader, leading to one of the greatest detective fiction quotes ever.
Gregory (Scotland Yard detective): Is there any other point to which you would wish to draw my attention?
Holmes: To the curious incident of the dog in the night-time.
Gregory: The dog did nothing in the night-time.
Holmes: That was the curious incident.
- All Encyclopedia Brown mysteries are deliberately like this... but some of the "solutions" are less plausible than others.
- Isaac Asimov deliberately wrote his Black Widowers mystery stories in this fashion.
- In Shirley Jackson's We Have Always Lived in the Castle, an entire family was murdered, and the answer to which of the three survivors committed the crime is fairly clued within.
- The Nero Wolfe stories by Rex Stout may or may not be Fair Play, since they're all narrated by Archie Goodwin, Wolfe's dogsbody and legman. Archie reports everything he finds to Wolfe, but Wolfe often doesn't return the favor, leaving both Archie and the readers in the dark. As a result, Archie and the reader usually have about the same chance of solving the mystery. If it is a Fair-play story, Archie will tell the readers at some point that he figured it out, and that they can too.
- The Ellery Queen novels — the first eight, which contain a nationality in the title, and the ninth, "Halfway House" — were like this, and would actually have a point before the solution where the story would pause and the author would tell the reader that they now have all the facts required to solve the mystery. This "Challenge to the Reader" was carried over to the Ellery Queen radio show and 1970s TV series, where Ellery would make a "Challenge to the Viewer" before the final ad break.
- Neil Gaiman says that he tried to make "Murder Mysteries" entirely solvable for acute enough readers — he even made the title a clue (as it implies that more than one murder took place).
- On the other hand, if you're not an acute reader, you might miss the fact that there were any murders other than the one in Raguel's story, namely that the narrator murdered his female friend and her daughter before encountering Raguel. This is not helped by the fact that even the murderer doesn't remember what he did as Raguel obliterates the memory of it from his mind. The comic book adaptation by P. Craig Russell makes it slightly more obvious.
- The stories of John Dickson Carr (as well as his pseudonym Carter Dickson) always showed you all the clues. (Even when the supernatural was involved, as in The Devil in Velvet, he always clearly laid out the rules the magic operated by.) The only problem was usually that the murder was impossible to begin with, so you couldn't figure out how, much less who. Carr even lampshaded the tar out of this in The Three Coffins when Dr. Fell stops in the middle of the novel to explain all the ways you can do a locked room mystery, because there was no point in pretending they weren't in such a novel. At the end of the chapter (yes, it's a full chapter of all the ways to pull one off) the other characters tell him that the two murders don't fit into any of his categories. They're really wrong.
- Carr's essay "The Greatest Game in the World" makes a key point about what makes a Fair-Play Whodunnit really fair, and good when done right: the key to the case isn't just one clue - a random word hidden in chapter six - but a system of interlocking clues that allow the reader to open a tapestry of interpretation that gives a larger picture: that of the truth.
- Scott Turow's Presumed Innocent delicately scatters its clues amidst character development and the trial plotline — all the reader needs is in the text.
- The Lord Darcy mysteries are an interesting case, in that they violate Rule #2 (since some of the characters have magical powers) and still manage to play fair with the reader. However, since the universe the stories are set in has consistent magical rules, Rule #2 could be said to be broken in letter but not in spirit. In some of the stories the whole point is that everyone assumes an impossible murder was done by magic, and Lord Darcy explains how it could have been committed in a perfectly mundane way. Magic is mostly used for forensics.
- Rule #1 is violated in at least one story, where a character whose point-of-view is followed later turns out to be the murderer.
- The Harry Potter books are like this; the mystery plot is deliberately littered with Red Herrings to lead Harry (and the reader, by extension) down the wrong path at first, but an acute reader can pick up on the actual clues and determine the true culprit before Harry does. For example, Harry Potter and the Chamber of Secrets drops several easily-missable clues about Ginny Weasley being the opener of the Chamber of Secrets, the most notable being Ginny crying out about having to go back and get her diary long before it becomes a major plot point.
- In fact, many readers who had become used to Rowling's extensive use of Chekhov's Gun and Chekhov's Gunman were able to figure out a couple of things the sixth book set up before the seventh book confirmed them: the identity of "R.A.B." and that Harry himself is a Horcrux.
- And even smaller ones, like the barman of the Hog's Head in book 5 being Dumbledore's brother, Aberforth.
- The Westing Game. Easy enough to follow that any elementary or middle school kid could have a chance of arriving at the correct answer.
- The Czech writer Josef Škvorecký wrote Sins for Father Knox, a collection of detective stories (later adapted as a TV series), each based on a violation of one of Knox's rules.
- Whether it does so successfully or not is a different story though for example Rule 3 is violated by having two secret passages right next to each other in an acceptable setting and Rule 5 is violated by having the killer's name spelled wrong on a dinner card hiding her "Chinaman" status and falls under Values Dissonance with Rule 2 as the "supernatural" of that case has the killer be gay. And Rule 8 is arguably not broken at all since an astute reader could figure out the significance of walking around a car to get into the passenger seat without being outright told that it is a British model.)
- Willard Wright demanded that all detective fiction be Fair Play Whodunnits. When he wrote the Philo Vance novels (under the pen name S.S. Van Dine), he wrote them to code. Late in The Greene Murder Case, Vance even writes a multi-page summary of the crimes, officially to help focus his thoughts, but it makes sure the reader is up to speed as well.
- "The Oxford Murders" (no, NOT related to this one) has been termed (citation needed) "the most fair whodunnit of all" - the author reveals the murderer on the first page in open light - if you have eyes to see. If you HAVE to be spoilered: The FIRST page. The poem. Which is not ancient at all, but faked. Which you COULD see simply by the fact that the vain author "signed" it with his name inserted as acrostichon. The victim, a wordplay fan, saw that immediately and was murdered by the author to hide the fake.
Live Action TV
- Murder, She Wrote actually had quite a few, given that the killers usually revealed themselves by saying something only the killer would know or assume.
- The occasional Law & Order spin-off (although not the original, for reasons related to its structure) will do this, probably more or less by accident.
- Law & Order: Criminal Intent does this more often than the others. Excluding the cases where you know who did it from the very beginning about a third of the shows have enough clues to solve it part way though, a couple can almost be deciphered based on the opening.
- Some episodes of Monk, before a point where they sometimes stopped caring about the mystery aspect of the show. In the early seasons, what set Monk apart was his ability to notice important clues and details that other detectives didn't see, and he would then point them out. At that point it was often possible to put them together and solve the case along with Monk. Sometimes, clues are revealed to us before Monk even notices them.
- The British game show Whodunnit? (UK) was based upon this concept.
- Star Trek: Deep Space Nine: Arissa asks Odo if he's worked out who the killer in the book was. He says "by the third page." Either he's just that good or the book's just that bad.
- Jonathan Creek was well liked among those who enjoy fair play mysteries, since even though the solutions to the various mysteries were always unusual and required lateral thinking, you always got to see everything the heroes saw that allowed them to solve the puzzle, and usually even had them highlight the significance of the clues.
- The short-lived Scene of the Crime, hosted by Orson Welles, was an attempt at a series revolving around a different fair-play mystery or two per episode.
- The Cluedo TV series.
- The early episodes of The Mentalist.
- Japanese live action series Furuhata Ninzaburou, in addition to being a Reverse Whodunnit, also provides additional clues to show the viewer how Furuhata ends up on the trail of the suspect. Like the Ellery Queen example, he would pause just before the final act to address the viewer and give them hints as to why he believes that the chief suspect did it, and what evidence there is to force a confession.
- The episode guest starring baseball player Ichiro goes even further than usual, as Not-Really-Ichiro goes out of his way to leave a clue at the scene because he believes in fair play.
- Sleuth 101
- "A Study in Pink" on BBC's Sherlock was fair play for the "who" part if not the "how" and "why." The audience knows what all five victims had in common - taking a taxi - and they are also aware of at least some of Sherlock's thought processes ("Who do we trust, even though we don't know them? Who passes unnoticed wherever they go? Who hunts in the middle of a crowd?"). Sherlock said that the murderer must have driven the victim somewhere and when John texts the murderer, a taxi shows up at the crime scene - Sherlock and John initially assume it must be the passenger, not realizing that it's actually the driver. Viewers had enough information to figure it out before the climax.
- For the more genre-savvy or genius watchers, many minor clues, or even the whole plot, can be guessed before the episode's end.
- The Doctor Who story "The Empty Child"/"The Doctor Dances": Enough clues are presented for savvy viewers to solve the riddle before the Doctor does.
- Most Psych episodes are fair play, especially since clues are highlighted for the viewer as Shawn sees them, plus the viewer sees the opening flashback which always relates to the story at hand. The exceptions are usually cases where Shawn doesn't figure out who the bad guy is, either, like with Yang and Yin.
- The first season of Remington Steele aimed for fair-play mysteries, with varying degrees of success. Then the network made them dumb down the scripts, so as not to alienate viewers.
- Ellery Queen: The TV series reflected most of the books in this regard.
- Zig-zagged in Williams Electronics' WHO dunnit. The clues for each case are just illustrations on the playfield and don't have any specific relevance to a particular case. On the other hand, interrogating a suspect always provides a clue to the killer's identity, allowing attentive players to easily solve it.
- The two mystery subquests in Knights of the Old Republic play completely fair, given that it's up to you to solve them. (Admittedly, one isn't much of a mystery, though.)
- There are a LOT of Red Herrings to make it look more difficult than it is—especially given the black and white morality of the rest of the game.
- In the Ace Attorney games, since the focus is entirely on the clues and how they fit together, it is occasionally entirely possible to figure out who the killer is before The Reveal. This is, of course, when the mystery isn't already a Reverse Whodunnit, or Clueless Mystery. The hard part, of course, is proving it.
- It gets ridiculous in the last case of Ace Attorney Investigations. Edgeworth figures out the culprit easily, but proving exactly what happened and how it was done is such a laborious process that you're given a save point in the middle of the interrogation.
- The mystery in the second chapter of The Witcher is done fairly, perhaps even generously, giving the player multiple opportunities to gather all clues. The best rewards are for solving it through questioning suspects and studying books before even looking at physical evidence. Failing to solve it leaves the player with reduced experience gains and a disadvantage in the confrontation with the real culprit.
- Persona 4 counts. The player is given all the information, and the culprit is someone they know. In the endgame, the player is given a list of all the characters (s)he has met so far, and a set of clues which should narrow it down to one person. They must then select the culprit correctly within three guesses, or be foisted off with a bad ending. Unfortunately, there's 80 hours of dungeon crawling between those vital clues and the event when it becomes crucial to remember them.
- Luckily, the culprit has a scene shortly before the player must make their choice, where a sharp player will notice that character saying something they can't possibly know about the kidnappings unless they were either responsible or in the party. And obviously it's not the second one.
- The list of suspects given is also easily narrowed down from, since it can't be anyone in the party, any social links, or the guy that was just established as not being the culprit. Although, the "social link" part doesn't work in the process of elimination in the Updated Re-release...
- There is still one vital clue that the player needs to remember. The killer left the player a threatening note in their own house while they weren't there, and they didn't break in. The killer must be someone that Dojima and Nanako trust.
- The Eagle Eye Mysteries PC game series eventually becomes this for older and more seasoned and experienced players.
- RuneScape has two murder mystery side quests, and both of these whodunnits are easily of the fair variety:
- The oldest, which is appropriately titled Murder Mystery, is essentially Board Game/Clue. Pay attention to the clues you find, and it should be easy to deduce who did it.
- The other one, One Piercing Note, was one of the first quests to feature real instrumentation and voice acting. It's a lot more story-heavy than Murder Mystery and it has a higher death toll. While the supernatural explanation can't be completely ruled out due to the setting, it's pretty obviously the least probable explanation for the murder mystery itself, and the murders are committed through perfectly normal means.
- Of all things, Borderlands2 has one of these. A man is murdered in Sanctuary and there is a confirmed description of the killer... only he's one of four quadruplets. Interviewing everyone will reveal vital clues, however:
- The victim was killed with a bullet, so only those with a weapon that fires bullets could've killed him.
- The killer barged into Moxxi's bar demanding safety which Moxxi couldn't guarantee. He threatened her so Moxxi pulled out her gun and shot him a couple of time which broke through his shield as he fled.
- Finally, Zed patched the one who Moxxi shot after he came to his clinic while injured. All of the brothers have visible health bars but the killer's is the only one that's full.
- The When They Cry mysteries have Fair Play solutions, but apparent violations are used to misdirect the viewer, and either come from unreliable sources, or they're irrelevant to whodunnit and how.
- Umineko no Naku Koro ni starts out rather questionably if it's a mystery or a fantasy, and it's the main conflict of the first four arcs - as in the characters actually argue over the genre: Beatrice insists that she killed everyone with magic while Battler refuses to believe that magic exists at all, though he also handicaps himself by refusing to admit that this means someone he knows committed the murders. As the story progresses, we're first shown Beatrice killing everyone with magic, which makes Battler despair until it's explained that anything not seen from the personal perspective of his piece on the 'game board' is unreliable information. In the fifth arc, the reader is presented with the Knox's Decalogue as a hint to solving the mysteries presented with a further hint being that if it's possible for Battler to be right, then the story must by definition be a Fair Play Whodunnit. The only question is whether he can figure out how it was actually done or, more importantly, the real meaning of the game and what magic actually is.
- Higurashi no Naku Koro ni, Umineko's predecessor, also has the same theme running much more quietly in the background. It is possible to figure out how things are occurring by the end end of the first half of the story, though perhaps not why. Of course, the crime may not be exactly what you've been led to believe, which may trick you into believing there has been a rules violation when Keiichi goes crazy and kills his friends.
- Discussed in Virtue's Last Reward, but also immediately dismissed by Sigma, who due to his more or less Ripple-Effect-Proof Memory is able to bypass Rule 6. Even though the game violently smashes every rule, it still manages to emcompess the SPIRIT of the rules, unlike most examples of this, by having the very spirit of why every rule exists being intact, while still breaking the fundamental rules themselves. This is done through a mixture of ways. Rue
- For example rule 8 is broken by Sigma revealing information that he shouldn't yet know, confusing other characters and having the timelines you go done have moments of Sigma sporadically pulling information from timelines the player most likely hasn't gone down yet. However, the player never once knows more then Sigma. In fact, in many occasions, it's the OTHER WAY AROUND. The game also makes you play down a timeline that Sigma has pulled information from first, before you can see the moment in the other timeline where Sigma states the info' he pulled [this is achieved by using "path blocks" that cuts the scene whenever Sigma is about to say something the player shouldn't yet know].
- Rule 2 is also broken by, of course, the constant mind leaping, and time stuff. But the essence of why the rule is included; so that supernatural stuff can't just be used as an Ass Pull, is respected and never broken. Every element of the supernatural abilities is explained with actual scientific, if hard to believe, explanations, and the entire thing is laid on a plate for the player at the start. There's never a single moment where the supernatural elements are treated as anything other then established points, as normal to the in-game universe as, say, jet-travel is in the real world.
- Rule 7 is MASSIVELY broken. Sigma himself is Zero. But once again, the game pays homage and never breaks the reason for the rule existing: It never has the 'detective' turn out to be "the bad guy", therefore breaking the entire point of the story. Sigma himself is just as shocked as anyone to learn that he was the 'criminal' all along.
- Rule 4: The reason some things are given long scientific explanations in game are because those explanations become vital later on, and are used for a number of "loop-hole" breakages, once again making sure that the reason the rule exists; to prevent pointlessly confusing dialogue and banter, is not broken.
- In fact, this can be applied to ALL the rules. They're all broken, but pay respect to the reason they all exist: To present a fair who dunnit. The player never knows too little, and the mystery always maintains "the basic rules" despite breaking all the fundamental commandments. The game pretty much straight out screams to the player "we're breaking these rules and we're proud!" at mainly since the game actually has one of it's "hidden files" being the 10 rules.
- Sigma himself is called out on this by Luna, who uses rule 6 to discount his argument, when he used information from another timeline. Sigma uses this example as to why he didn't do anything wrong: The two timelines, timeline A and B, both stream from timeline P. Since timeline A and B both run of the same "time", one that came from timeline P, and since he himself can timeline jump, him taking information from timeline A and using it in timeline B isn't breaking any rules. He also goes on to say that if he had taken info from timeline A then gone back to timeline P and used the info to change the branches, then she would have a point. But as he never actually used information he couldn't otherwise know to change the OUTCOME of the timelines, which is the fundamental reason why rule 6 exists, he's not doing anything wrong.
- Danganronpa generally follows the decalogue, although rule 6 (and 10 later on) is broken in a number of scenes. However, one of the cases is unpredictable before the trial happens, and in another case, there's not enough information to conclusively answer it at all.
- Hanai's route in Metro PD: Close to You provides the audience with all of the facts needed to solve the mystery. Unfortunately, combined with the Law of Conservation of Detail and the fact that the VN's focus is more on romance than on mystery, this means that the reader will probably have it figured out well before any of the detectives do.
- The Big Idea of the Whateley Universe is a Fair Play Whodunnit, even though the superpowers of the characters add complications over the usual detective story. The reader even has more information than Reach, the character who plays the detective in the story.
- Lampshaded in the theme song to A Pup Named Scooby-Doo, which was quite a bit more fair than the Clueless Mystery-type escapades of the previous series.
- A lot of later series became more fair when it came to mysteries, though some would return to the Clueless Mystery route (but they would usually at least try to lampshade it).
- The first few Sideshow Bob episodes of The Simpsons were this kind of story. Later on, the writers abandoned the mystery angle because coming up with them proved too difficult.
- And of course special mention must go to the 2-part Season 6 closer/Season 7 opener "Who Shot Mr. Burns?" Even though the culprit did seem to come out of the blue, the clues were indeed all there, with the mystery even being drummed up as a contest to see who could figure it out. In fact, the culprit was actually properly identified by a fan of the show, legitimately using the clues presented, in the summer between the two episodes. Sadly, he didn't actually win anything.
- The writers lampshade this by ending the first part with Dr. Hibbert turning to the viewer and saying "Well, I couldn't possibly solve this mystery...can YOU?" Then the camera pans back and we realize he's actually talking to Chief Wiggum.
- The reason the fan didn't win was because the contest was so poorly designed. The way it worked was that of all the entries, the producers would choose a thousand, out of which they would pick whoever sent in the correct answer. Unfortunately, from the thousand that they picked, no one actually had the correct answer. You would assume that they would just start again with another thousand, but the rules specifically stated that the winner had to be out of the first thousand picked. So, they just chose someone randomly. Of course, this meant that any number of people could have sent in the correct culprit, just were unlucky to not wind up in the final thousand.
- Pops up in My Little Pony: Friendship Is Magic in several episodes.
