"I don't know, but I think you've got one in your pocketses!"
In Classical Mythology, Oedipus encountered a Sphinx and was, famously, forced to solve the Riddle of the Sphinx in order to pass. Ever since, it's been a tradition that all sphinxes ask riddles. So if you see a sphinx, be prepared for a game of Riddle Me This.
The classic Riddle of the Sphinx still appears occasionally, but most sphinxes will come up with their own new ones, since, let's be honest here, everyone knows the answer to the original.
Exactly why sphinxes are driven to do this varies from work to work. Sometimes sphinxes will be depicted as enjoying mental challenges and games of wits, sometimes they'll have mental compulsions driving them to engage others in this manner, and sometimes they'll simply ask riddles without any specific explanation provided for why they do this.

- The AncientSphinxmon from Episode 58 of Digimon Ghost Game has a pattern of attacking people near cultural or recreational sites through forcefully taking off his victim's shoes and forcing them to trip, then ask them riddles. If the victim fails to answer his riddles correctly, he forces stone to manifest inside the victim and encases them, turning them into golden bricks. He eventually accumulates enough victims to create a massive pyramid that can resurrect his boss, Pharaohmon.
- Tamagotchi: Mametchi and his friends come across one resembling Kuchipatchi in episode 136. It asks the standard Riddle of the Sphinx ("What walks on four legs in the morning, two legs in the afternoon, three legs in the evening, and no legs at night?"), which Mametchi almost answers with a Tamagotchi before realizing not all Tamagotchis have legs in the first place, with the Gotchi King in particular coming to mind. He changes his guess to a human, which is the correct answer and allows him and his friends to continue their search for the Crystal Crown.
- Ulysses 31: The 31st century space version of Ulysses bumps into a space version of the Sphinx in one episode. It naturally asks him the standard Riddle of the Sphinx, though this time the Shpinx has a daughter and she wants to keep Ulysses for herself, so she submits him to further challenges hoping he loses and becomes her slave/lover.
- An Omake in Yaiba, the racers of the Chiki Chiki Gran Prix must, as their first challenge, answer a single riddle from the Sphinx (depicted as a living counterpart of the statue). Unfortunately for the Sphinx, Yaiba is truly an Idiot Hero of staggering proportions, keeping the guardian awake the entire night in an attempt to solve his riddles, much to the Sphinx's frustration. Eventually, he gets to pass (barely) by answering the following riddle: "What's the first letter of the alphabet?".
- In the second segment of Pleasant Goat Fun Class: Sports are Fun episode 22, Weslie, dressed as a sphinx, guards a treasure chest and has the other goats answer the question of what events are featured in the Ironman Triathlon to obtain the treasure.

- Master of Predicaments lets you pick a card in your hand and then force the opponent to guess if its mana value is greater than 4. If they guess wrongly, you can cast that card for free.
- Even sphinxes who don't have riddle-related gameplay will often reference riddles in their Flavor Text, because hey, that's what sphinxes do.
- The Sphinx of the Steel Wind, however, gives the impression that she isn't really interested in this kind of thing. All of her abilities are bluntly powerful combat abilities rather than clever, tricky ones, and her favorite riddle — which, as the card notes, nobody's ever answered to her satisfaction — is "why should I spare your life?"
- In Test of Metal, Tezzeret's attempts at solving riddles left by the mad sphinx Crucius are a major plot point.

- Shadowchasers Series mentions several sphinxes.
- The sphinx Athentia was a seer who gave advice to powerful individuals, but inflicted a "conundrum curse" upon them as a result, turning the recipient into a type of living riddle who could do nothing but try to solve it until he succeeded. Jamor Stormbringer challenged her to a game of riddles, offering his eternal servitude as a slave if he lost, if she would grant him immortality if he won. Too egotistical to believe she would lose, Athentia accepted, and the resulting contest lasted days. She missed one, but that was enough for Jamor to win. This was an important motivation for the villain in the original story, who was Athentia's daughter.
- It is briefly mentioned that one sphinx cheated because the answer to her riddle was "Kill Me". The other sphinxes admired her for being so clever and wanted to use her riddle, but sphinxes are not allowed to copy riddles. However, one sphinx thought her trick was dishonorable and helped the Shadowchasers capture her.
- Through The Well Of Pirene: Amelia, Wire and the CMC meet one in the Cup palace, who offers them the typical three riddles or death trial.

They don't answer it — Sweetie Belle has an emotional breakdown and starts crying and begging the sphinx not to kill them, which guilts her into just letting them go.
- Harry Is a Dragon, and That's OK:
- Tanisis Sanura, a sphinx student who enrolls in Harry's second year thanks to the new law passed in the Wizengamot. She spends her first night at Hogwarts holding up all the rest of Ravenclaw House exchanging riddles with the doorknocker! Also, she has to repress her instinctual reaction to an incorrectly-answered riddle.
- Tanisis' mother is the sphinx utilised as an obstacle in the Triwizard Tournament hedge maze task.

(Kay'la comes up with a solution anyway, so the sphinx can reveal how to defeat him)
- Pleasant Goat and Big Big Wolf: The Tiger Prowess: Two sphinxes, one with a goat's head and one with a wolf's head, guard the temple of the totem and ask Weslie and Wolffy how many stars are in the sky. Weslie replies by saying there are as many stars in the sky as there are grains of sand in the desert, prompting the sphinxes to start counting the grains of sand. By the time Weslie and Wolffy make it out of the temple with the totem, the sphinxes are still counting the grains of sand.
- Mirrormask has gryphons and sphinxes, which are similar catlike creatures with human heads, but mixes up their properties. In the film, a gryphon guards the area known as Giants Orbiting, requiring Helena answer the classic Riddle (she succeeds by giving a literal answer) and stump him in return (she gives him something unsolvable and sneaks off while he's thinking about it).

At the end of the novel, Escalia and the Justicar take the time to rescue Enid on the way out and she ends up traveling with them.
- Harry Potter: In Harry Potter and the Goblet of Fire, Harry encounters a sphinx in the hedge maze and has to answer a riddle in order to pass by it safely; however, she does tell Harry that if he decides not to give an answer and just retreat, she won't stop him. Fantastic Beasts and Where to Find Them states this as the reason the sphinx is classed as a beast rather than a being, as it only speaks in riddles and puzzles and reacts violently if given the wrong answer.
- The Infernal Machine, a retelling of the legend of Oedipus, gives an Alternative Character Interpretation of the Theban Sphinx, where she is changed to a sympathetic character. She would have won the contest, as Oedipus cannot guess the answer to her riddle, but she tells him the answer, simply so she can end her life and be free of the curse that compels her to kill and also to make him love her. (Explaining why she leaps off the cliff later.) Unfortunately, he leaves without so much as saying thank you. The scene ends with Anubis taking her soul to Heaven.
- The Neverending Story: The Southern Oracle is protected by two stone sphinxes whose gazes trap a victim within their own mind until he answers every riddle in the world. All their victims die of thirst long before coming close to finishing.

- Percy Jackson and the Olympians: When the half-bloods meet a sphinx in the Labyrinth in Battle of the Labyrinth, it tries to administer a multiple-choice standardized test, with mundane trivia questions. Annabeth, who was expecting a riddle that would test her cleverness, is not amused.
- In Pyramids, a sphinx asks Pteppic the Riddle of the Sphinx. Pteppic nitpicks the metaphor and manages to leave the sphinx confused enough that he can make a quick getaway.
- Skippyjon Jones: In one story, the title character is asked this riddle by an Egyptian Sphinx parody called "the Finx". The answer is Skippyjon, AKA Skippito Friskito, himself.
Whose ears are too big for his head?
And who loves to go bounce on his bed?
Who creeps on all fours,
through his own closet door,
straight into the Land of the Dead?
- A Song of Ice and Fire: Referred to, without an actual sphinx. Of Alleras, who is nicknamed "The Sphinx", Maester Aemon tells Samwell that "the Sphinx is the riddle, not the riddler."
- Kyōryū Sentai Zyuranger: Dora Sphinx (King Sphinx in Mighty Morphin' Power Rangers) takes the human form of a game show host who asks riddles to children (and later, the Rangers), and traps them inside trees when they answer wrong. He even asks the classic sphinx riddle to stump the first kid at the beginning of the episode. The heroes eventually turn this against him, defeating him by tricking him into asking them what his weak point is (because he always reveals the correct answer to riddles after receiving a wrong answer). Geki cleverly turns this against him earlier too when Dora Sphinx's riddle is what is the absolute in the universe (Sphinx says "evil") but Geki says that he believes it is "justice" and since it's a subjective question (given that good and evil were battling it out right there) they can't have their answer until one of them wins, which locks Dora Sphinx out of giving him riddles from then on.
- Inverted in Embers in the Dusk. The local Sphinxes are riddle solvers, and are quite willing to help the humans out with riddles like "what's the access code for this ancient data archive?".
- Dungeons & Dragons: Sphinxes are generally associated with either riddles or with knowledge in the broad sense. One supplement lists potential riddles for sphinxes to use; one, which she uses when she's too hungry to play fair, has as its answer "Kill me".
- Module I3 Pharaoh: Inside the tomb of Amun-re the PCs can encounter an androsphinx who offers to play a Riddle Me This game with them. If they can answer one of his riddles he will answer a question from them about the tomb. Riddles he can ask include the Riddle of the Sphinx or a Knights and Knaves (Group A always tells the truth and Group B always lies) logic puzzle.
- Dracosphinxes subvert this; these monsters have the heads, fiery breath, avarice and treachery of red dragons, so if they engage other creatures in a game of riddles, it's a ruse to get them to lower their guard so the dracosphinx can make a sudden attack.
- In 4th Edition, there are sphinxes with magical powers that make games of riddles more dangerous. A normal sphinx (presented as a guardian of tombs and sacred areas) is bound to ask a riddle and let intruders pass if they can answer it. However, if they answer wrong, the sphinx becomes stronger. (In game terms, it gains a temporary bonus to its attack rolls, defenses, one action point, and a second use of a powerful ability it can use to heal itself.)
- The sphinx mystery is an even deadlier creature that challenges prey with riddles for fun instead of attacking outright. One powerful supernatural ability she has (called "Riddle Me This", appropriately) is a mild curse that causes mental damage to a victim if he doesn't at least try to answer her riddle once per round, and does not end until he tries to answer it. (If the victim gets help from an ally, the spell is broken, but he takes damage one last time.) The Game Master doesn't even need an actual riddle; the victim needs to make a History Skill check to solve the riddle. Note that while a wrong answer will end the curse, if a wrong answer is given by a victim who is under it, the sphinx mystery gains the ability to reuse a very powerful physical attack called Corrective Mauling; given what the usual penalty for a wrong answer is, this clearly gives her an advantage. (Also, a sphinx mystery is under no real obligation to let a victim go if he answers correctly; Riddle Me This is an At Will ability that it can even use while fighting, so in theory it could ask riddles over and over again during combat. However, the source does say that it might not attack at all if a potential victim simply plays along and answers them.)
- Spelljammer: Astrosphinxes are mad, evil sphinxes that compulsively ask inane, unanswerable riddles and questions (such as "what's the speed of down?" or "how loud is blue?"). When an answer inevitably fails to come, the astrosphinx tries to kill the one it was asked to. Since an astrosphinx's madness leads it to interrogate everything it meets, including things like wildlife, insects and plants, they tend to strip entire planets of life if allowed to run free in this manner. They can be defeated by giving them equally mad answers, which has a 1% chance of causing the astrosphinx to explode in a shower of lightning bolts.
- Module S2 White Plume Mountain, described as "the puzzle dungeon to end all puzzle dungeons", has one corridor guarded by a gynosphinx who will only let you past if you solve her riddle (or come up with creative workarounds such as seen in the novel, above, and Nodwick, below).
- Pathfinder has several subtypes of sphinx, with each variety having a different take on the association with riddles.
- Gynosphinxes love riddles and logical puzzles, and offering one a tempting new riddle to ponder is a fairly efficient way to defuse a bad encounter with one.
- Androsphinxes are much like gynosphinxes, but far more intellectual and emotionally aloof; they have relatively little interest in riddles and games of wit, but enjoy pondering complex philosophical questions.
- Criosphinxes are comparatively dim-witted (though still above the average human). They lust ceaselessly after gynosphinxes and, whilst they don't value riddles themselves, they known that gynosphinxes do and will seek out knowledge of riddles in order to bargain their way into a gynosphinx's good graces.
- Hieracosphinxes are the Always Chaotic Evil branch of the sphinx family (literally), and are too brutal, stupid (this time objectively rather than comparatively) and foul to care about knowledge or wits one way or the other. In general, they will just skip straight to attacking travelers rather than asking them anything.
- Elder sphinxes have the ability to telepathically project a litany of riddles, puzzles and paradoxes so complex that every creature within sixty feet of them needs to pass a willpower test or become stunned for a number of rounds. Creatures that pass the check, however, gain valuable insights into the sphinx's mind — in game terms, they take a bonus to all Knowledge checks for an hour.
- Areshkagal, the demon lord of portals, greed and riddles, takes the form of a giant, faceless sphinx with batlike wings, six legs and a snake for a tail. She is often worshipped by evil sphinxes — and worshipped in giant sphinx statues — and her faithful inscribe riddles in their own skin in adoration of her. One of her boons allows her worshippers to tell riddles so vexing that they drive listeners insane.
- Pathfinder has several subtypes of sphinx, with each variety having a different take on the association with riddles.

- Board Game Online: A Sphinx is a possible obstacle in the archaeology dig and dungeon crawl events. It will pose you a trivia question, and you have to answer correctly to advance towards the artifact at the end.

- Born Under the Rain: As seen in a Sphinx's dialogue of a riddle, in an official screenshot.
- Chrono Cross has a Sphinx optional boss that you can beat through straight combat, or by correctly answering its riddles by hitting it with the proper color elements. The order of the answers to the riddles is the same as the order you need to use elements in the final battle to get the True Ending... not that there's any indication of this.
- Cragne Manor: Discussed by Bethany. She visited a desert house that had two sphynxes in it. She gets along great with one, but the other one is mad at her because she solved all its riddles in three minutes. Bethany offered to help it come up with new ones, but now it just rolls its eyes at her and makes fart noises when she tries to talk to it.

- Shadowgate: One of the tasks is to give a Sphinx three objects that answer three riddles he gives.
- Super Mario Bros.:

- Super Mario Odyssey: An Egyptian sphinx appears in various Kingdoms, where it guards passageways. He only lets Mario get past it if he correctly answers a series of questions. It travels between Kingdoms with a giant sail and will grant Mario a Power Moon if he spots him with the binoculars. It admits the that questions Mario answers aren't much riddles at all.
- Wario: Master of Disguise has a sphinx as the boss of the third level. It asks you a series of questions, and if you answer them wrong, it kills you.
- Mixed Myth: The protagonist runs afoul of a sphinx early on in the story. The answer she gives sounds like it should be right, which causes the sphinx to realize that it's been so long since someone got it right that she's forgotten what the right answer is, so they'll have to head back to her home to check the answer (our heroine is wrong, but gets points for creativity, which lets her off the hook since she managed to endear herself to the sphinx on the journey).
- The party encounters a riddling sphinx in a dungeon. They bribe it to let them pass, even though Nodwick knew the answer.
Nodwick: The answer [to the riddle] was "money", by the way.
Yeagar: Weren't you paying attention? The answer is always money!
- In another instance, in the module-parody strip "Climb Every (White Plume) Mountain" the answer to the riddle is "the moon". Nodwick is annoyed (and disgusted) that the sphinx was willing to accept Yeagar's display of frustration instead of a verbal response.
- The party encounters a riddling sphinx in a dungeon. They bribe it to let them pass, even though Nodwick knew the answer.
- Oglaf: "Stumper" has the sphinx mime a book opening and angrily yell the answer when the guy doesn't get it... which gets her disqualified. The Alt Text says the (Egpytian-headdress-wearing) sphinx is actually Greek, hence the riddle.
- The Order of the Stick: Parodied in an extra strip in the book edition of the fifth arc, "Blood Runs in the Family". The heroes visit a roadside stop with a sphinx (with acne) as a cashier. Not only does the sphinx speak in riddles, but to ask it a question, one needs to phrase it as a riddle as well, even a prosaic question like "which way is the restroom?". Elan, being a bard, is adept at it, but when Vaarsuvius tries it, his/her Sesquipedalian Loquaciousness ends up confusing the sphinx... resulting in a shower of confetti and a reward of a free ice cream cone for managing such a feat. Haley was able to get a second cone by having V ask it how many flavors of ice cream it had.
- Paranatural: Max and Isaac find a sphinx-like creature that tells them to answer correctly two of his three riddles. The first one seems to be the classic Riddle of the Sphinx but the answer was "that guy" (a random passerby monster).

- PepsiaPhobia features a sphinx who is repeatedly humiliated because she only knows the one riddle, and everyone, even the little kid, knows the answer already.
- Skin Deep: Played with. Michelle Jocasta, who is a Sphinx — specially a winged grecian sphinx, as opposed to a wingless Egyptian sphinxes that also exist in the comic — once dressed up for Halloween as the Riddler, because she thinks she's being clever. As a general rule, it's averted with her. Word of God states that she's no more prone to asking riddles than any other person. She does, however, have undeveloped oracular powers, as this is an inborn trait of sphinxes.
- Skin Horse: Inverted with the Antisphinx. Only Smart People May Pass, but you have to come up with a riddle it can't answer. And there's a further twist: this does not mean a riddle it can't answer correctly.
- Slack Wyrm: Rene the Sphinx is in the habit of imprisoning people who can't answer his riddles and not letting them go until they get one right, although his "riddles" tend to be less mental challenges and more direct questions about why his wife left him or why you only realize you were happy when you become unhappy.
- Wapsi Square: Phix sets the same riddle to both Monica and Shelly as a test to see if they're ready to fix the Calender Machine. They each give different answers and Phix rewards them both — without, however, saying that either answer is right.

- Kidd Video had the Pink Sphinx in one episode, who wakes up every thousand years and can grant a wish to whoever solves a riddle.

When Somnambula came to rescue the kidnapped prince, the sphinx demanded that she solve a riddle before being permitted to do so.

The Sphinx says that if they answer her riddle correctly, she'll devour herself and the trio can pass. She adds that if they answer incorrectly, she'll devour each of them. The Running Gag of the sketch is that the trio keeps getting the right answers using the wrong work and telling the sphinx that she has to eat herself. The third and final time she grows so sick of their success that she simply complies to avoid having to deal with them any longer.
