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.
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.
- 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.
- 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).

Eventually, he gets to pass (barely) by answering the following riddle: "What's the first letter of the alphabet?".

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. Amelia answers the first two through a combination of clichedness on the sphinx's part and genre savvyness on hers, but the third proves much trickier. 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.

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?

- 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.

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).
- 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.
- 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.

- 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.

- GastroPhobia features a sphinx who is repeatedly humiliated because she only knows the one riddle, and everyone, even the little kid, knows the answer already.
- 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, 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). Later on we see Isaac faoling the last riddle and so he can't cross the Sphinx's bridge magical barrier... but since the "bridge" is only a plank over a small stream, he just casually walks over it.
- 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.

- 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.

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

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.
