Has Cicada 3301 Been Solved Yet?
A Look into the Internet’s Greatest Mystery
Cicada 3301 is the nickname for a series of incredibly complex, unsolved puzzles that first appeared on the internet in the early 2010s.
Often called “the most elaborate and mysterious puzzle of the Internet age”, it captivated thousands of curious minds worldwide with its blend of cryptography, steganography (hidden messages in media), and even real-world treasure hunts.
To this day, no one knows who created these puzzles or why. Many theories have been proposed. Some suspect it was a covert government experiment or recruitment test by a powerful agency, while others believe a secret society or hacker collective could be behind it.
In this article, we’ll dive into the origin of Cicada 3301, what the puzzle involved, why people became so obsessed with it, its legacy, and the latest known information about this enduring mystery.
The Origin: A Puzzle out of Nowhere

A stylized cicada insect logo and the number 3301 became the iconic signature of the mystery. On January 4, 2012, users of the 4chan internet forum encountered a strange post unlike anything seen before.
It was a simple black-and-white image with white text that read: “Hello. We are looking for highly intelligent individuals. To find them, we have devised a test… There is a message hidden in this image… Find it, and it will lead you on the road to finding us. We look forward to meeting the few who will make it all the way through. Good luck.”
It was signed “3301.”
Tech-savvy readers quickly realized this was no ordinary message: the image itself contained a hidden clue encoded within it.
Using steganography techniques (hiding data inside an image file), solvers extracted a secret string of text from the picture, which led to a web link as the next step of the puzzle. In other words, the Cicada 3301 post was an elaborate invitation to a scavenger hunt.
This mysterious image on 4chan marked the beginning of one of the most sophisticated internet riddles in history.
Once that first hidden message was found, the real journey began. Solvers following the trail found that each clue led to another, growing increasingly complex.
For example, one early clue pointed to a specific subreddit (a forum page) which contained a code referencing an 18th-century Welsh myth called “The Lady of the Fountain.” Decoding that eventually revealed a telephone number; when dialed, a prerecorded voice congratulated the caller and mentioned “three prime numbers” associated with the initial 4chan image, one of which was 3301 (a nod to Cicada’s signature).
And from there, things only got more bizarre and exciting.
As participants dug deeper, the puzzle broadened beyond the internet. Cicada 3301 began leaving physical clues in the real world, sending solvers on a global scavenger hunt. In later stages of the 2012 puzzle, the organizers posted GPS coordinates for locations across multiple countries, where they had planted posters with QR codes and enigmatic symbols.
From telephone poles in cities like Paris, Sydney, Warsaw, and Seoul, dedicated participants went out to find and scan these QR code flyers in person. Imagine an online riddle that actually sends people around the world on a treasure hunt. That was the level of commitment Cicada 3301 inspired.
By this point, it was clear that no single person could solve everything alone; the challenge required collaborative effort from a community of solvers pooling their knowledge.
Eventually, the trail of clues led the fastest solvers to a final private website on the Tor network (an anonymous “dark web” browser). This appeared to be the endgame of the 2012 puzzle.
However, only a select few who arrived first got access, while those who were slower were met with a discouraging note on the site: “We want the best, not the followers.” In other words, Cicada 3301 closed the door once they had enough top performers.
The few individuals who did make it all the way were presumably given further instructions or membership in whatever group was behind the puzzles, while everyone else was left in the dark. (Those who finished reportedly received a congratulatory email from Cicada 3301, but were likely sworn to secrecy about what came next.)
The initial puzzle had ended, but the mystery was only growing…and the internet was hooked.
The Puzzles Continue: 2012–2014 Timeline
The creators of Cicada 3301 didn’t stop after that first puzzle. In fact, they returned with new challenges each year for the next two years, forming a trilogy of legendary internet puzzles.
Here’s a brief timeline of the known Cicada 3301 events:
2012 Puzzle: The first puzzle began with the 4chan image on January 4, 2012 (as described above). It led participants through a series of digital clues (hidden messages in images, cryptographic ciphers, online forums) and even real-world locations to find posters and QR codes.
Those who solved every step were privately contacted by Cicada 3301 (reportedly via email) and reached the “final stage,” although what exactly that entailed remains secret. The vast majority of players only know that the winners were essentially told, congratulations, you solved it, and then went silent. The true “prize” of the puzzle was never publicly revealed, adding to the intrigue.
2013 Puzzle: Almost exactly one year later, on January 5, 2013, a new Cicada 3301 puzzle was announced with another image posted on 4chan’s boards. “Hello again. Our search for intelligent individuals now continues,” it began.
The second puzzle followed a similar format to 2012 but with increased difficulty; it introduced more complex cryptographic tasks, deeper literary references, and once again culminated in physical clues planted around the world. Just as before, only the quickest and most skilled solvers made it to the end.
Those who arrived late found the trail abruptly closed, forcing them to wait and hope for another chance the next year. Cicada 3301’s message was clear: they only wanted the absolute best problem-solvers, not just anyone who could follow others’ work.
2014 Puzzle: On January 4, 2014, Cicada 3301 returned for a third round, but this time the puzzle launch was slightly different. Instead of posting on 4chan, the group’s verified Twitter account suddenly posted an image with more obtuse, cryptic text than before.
This third puzzle introduced a mysterious digital manuscript titled “Liber Primus” (Latin for “First Book”). The Liber Primus was a 58-page book written entirely in runic characters, apparently created by Cicada 3301 themselves. Solvers were able to decode portions of this runic text, revealing philosophical and esoteric passages, but many pages of the book remained (and still remain) uncracked.
The Liber Primus is believed to hold the final key to the Cicada 3301 mystery; a message or instructions that might only emerge once the text is fully decoded. To date, however, the 2014 puzzle remains officially unsolved. No one has publicly announced completing it, and large chunks of the Liber Primus are still encrypted.
Notably, after 2014, Cicada 3301 did not release a new puzzle in January 2015, breaking the annual pattern. Aside from a small clue that appeared in 2016 and a final message in 2017 (more on those later), the puzzles ceased after the 2014 round.
Throughout these puzzle rounds, the anonymous organizers consistently implied that their goal was to recruit “highly intelligent individuals” via these tests.
The very first 2012 message said so, and winners later corroborated that Cicada 3301 asked them questions about their views on information freedom, privacy, and censorship…as if vetting candidates for a secret project or group.
What exactly that group does or did is still unknown, but the emphasis on cryptography and privacy hints at a possible mission related to internet security or anonymity.
What Did the Cicada 3301 Puzzle Involve?

So, what did Cicada 3301 actually consist of? In essence, it was a multi-layered, multi-media puzzle that required a broad range of skills and knowledge to solve.
The challenges were designed to test participants’ ingenuity in many areas. Here’s a breakdown of key elements and concepts that appeared in Cicada 3301’s puzzles:
Advanced Cryptography and Coding: Nearly every stage of Cicada 3301 involved cracking some form of cipher or code. Solvers encountered everything from classic cryptographic ciphers (like Caesar shifts and RSA encryption) to custom encryption schemes.
For example, participants had to know or learn about prime numbers, hashing algorithms, and programming tricks to decode messages. The puzzles were heavily focused on data security and encryption techniques, exactly the kinds of skills one would need in cybersecurity or codebreaking work.
Steganography (Hidden Messages in Images): The very first clue demonstrated this: Cicada 3301 hid information inside image files (and later in music files and other media) using steganography.
Solvers often had to use special tools to reveal hidden text or images buried in seemingly normal files. A simple photograph or a piece of digital art from Cicada might actually contain a secret URL or code if you knew how to extract it. This taught participants to “look beyond the obvious,” a recurring theme in the puzzle.
Literature, Philosophy, and Occult References: Cicada 3301 wasn’t just about tech — it also drew on a rich tapestry of books, poetry, and historical texts. Clues frequently referenced obscure literature ranging from medieval Welsh legends to modern cyberpunk writing.
For instance, one clue required knowledge of a poem from the Mabinogion (a collection of Welsh myths), and another involved a quotation from Agrippa, a rare electronic poem by William Gibson that was distributed only on floppy disks.
Participants also encountered references to works like The Book of the Law (an occult text by Aleister Crowley) and William Blake’s poetry, among others. The Liber Primus itself, with its runic script and philosophical tone, reads like something between a scripture and a riddle.
These high-brow references meant that solving Cicada 3301 required not just technical chops but also a breadth of knowledge in the humanities and an ability to interpret abstract or esoteric clues.
Real-World Treasure Hunt: Unlike many online puzzles, Cicada 3301 broke the fourth wall and entered the physical world. At certain points, solvers were given GPS coordinates and instructions to find something in real life.
Cicada agents (or perhaps local volunteers) had posted paper flyers with QR codes and cicada symbols in cities across North America, Europe, Asia, and Australia. These posters were often taped to telephone poles or street signs in locations from Warsaw, Poland to Seattle in the US. If you scanned the QR code on one of these posters, it would give you yet another clue or riddle to solve online.
The fact that Cicada’s mystery scavenger hunt spanned multiple continents made participants feel like they were part of a worldwide conspiracy or adventure. It also added urgency, as the physical clues were taken down quickly, suggesting only a handful of people were ever meant to find them in time.
Multi-Media and Original Content: The puzzles weren’t limited to text and images. Cicada 3301 incorporated custom-made media and software as part of the challenge. Solvers uncovered original music compositions (two pieces titled “The Instar Emergence” and “Interconnectedness”), which contained encoded messages in their sound or sheet music.
There was even a bootable Linux CD that Cicada released at one point. When participants ran it, it presented puzzles and clues in the code, implying the group had serious technical prowess to create their own operating system image for the game.
The use of an OpenPGP signature (a cryptographic digital signature) on every official message was another hallmark of Cicada 3301; it allowed solvers to verify that a clue truly came from the real Cicada (and not a hoaxer) by checking it against the group’s public cryptographic key.
This level of technical detail reassured players that they were following an authentic trail and highlighted the organizers’ emphasis on security and anonymity.
I have to stress that Cicada 3301 was not a commercial project or a typical Alternate Reality Game (ARG) designed for marketing or entertainment. Unlike most ARGs, it never promoted a product, never made money, and no company or individual ever claimed credit for it. It appeared to be a purely intellectual challenge, or perhaps an elaborate recruitment tool, operating in complete secrecy.
Why People Became Obsessed with Cicada 3301

Cicada 3301 sparked an almost fanatical following in some corners of the internet. What made thousands of people dedicate countless hours (and many sleepless nights) to solving these puzzles?
Several factors contributed to the obsession:
Unprecedented Challenge: The Cicada puzzles were hard. They combined a wide array of disciplines in ways people had never seen before online. Solvers had to be part computer scientist, part cryptographer, part literature professor, and part treasure hunter.
This level of difficulty and complexity was incredibly enticing to those who love puzzles and problem-solving. Being told “we’re looking for highly intelligent individuals” was like catnip; a direct dare to rise to the challenge.
As one commentator noted, Cicada 3301 was arguably the internet’s most elaborate mystery, which naturally attracted elite puzzle-solvers eager to test their mettle.
The Mystery of the Puppet Master: Unlike a normal contest, here nobody knew who was running the show or what the ultimate goal was. Was it a hacker group? A government agency? A secret society? This anonymity added a huge aura of mystery.
Participants weren’t just solving puzzles; they were trying to piece together who and why. Every clue solved felt like it might reveal the identity or motive of the elusive “3301.” This is a big reason people became so obsessed, as the human brain loves a good mystery, and Cicada 3301 was an extremely tantalizing one.
The puzzles’ content even fueled this curiosity by touching on themes of privacy, cryptography, and forbidden knowledge, which led many to speculate that a powerful organization or agency was behind it.
Community & Collaboration: Cicada 3301 might have started as a competition, but it quickly became a community effort. Thousands of individuals around the world congregated on message boards, chat rooms, Reddit threads, and IRC channels to share findings and work together on solutions.
People who didn’t even know each other in real life were pooling their talents. A coder would team up with a linguist, or a math PhD with a history buff, all united by the common goal of cracking Cicada’s codes. This collaborative spirit created a buzz of excitement and camaraderie online.
According to reports at the time, forums would be active through the night with users brainstorming solutions, comparing notes, and eagerly awaiting new clues. In a sense, Cicada 3301 became a massively multiplayer puzzle, and being part of that global solver community was thrilling in its own right.
The Thrill of a Real-Life Adventure: The moment Cicada sent players out into the physical world (to find QR codes on lampposts and such), it crossed into legend. Suddenly this was more than a computer puzzle; it felt like a spy novel come to life.
Solvers found themselves chasing clues across cities, which provided a rush of adrenaline and adventure. Even those who only watched from home could feel the excitement as pictures of found QR code posters in different countries popped up online.
Few internet phenomena break the barrier into the real world like this, and it gave Cicada 3301 a unique, almost cinematic appeal. It’s the kind of mystery that makes you think, “If I’m smart (or lucky) enough, I might end up flying to another country or uncovering a hidden artifact.” That’s an addictive prospect.
A Hint of a Greater Reward: Lastly, a huge factor was the implied reward. The Cicada 3301 messages suggested that those who solve everything would “meet” the organization or be welcomed into something special. Indeed, the first puzzle’s winners were privately contacted, and Cicada explicitly said they were looking to recruit exceptional individuals.
This led many participants to dream about what lay at the end of the road. Perhaps it was a high-paying job offer from a tech company or intelligence agency; maybe it was admission into a secret society of geniuses; it could even have been access to some earth-shattering knowledge.
The truth is, we still don’t know what successful solvers actually got (beyond the puzzle-solving experience itself). But just the possibility of a secretive and significant reward (essentially, the allure of being one of the chosen few) drove people to pour their hearts into the challenge.
Cicada reinforced this by emphasizing quality over quantity (e.g. the “We want the best, not the followers” message), implying that if you make it, you’re truly special. For many, that intangible reward of recognition and belonging was enough motivation to keep going.
In short, Cicada 3301 hit the perfect storm of factors to create an online obsession: it had the intellectual appeal of a fiendish puzzle, the emotional appeal of a deep mystery, and the social appeal of a collaborative quest and potential secret prize. It’s no wonder it became one of the most talked-about internet mysteries of its time.
Legacy and Latest Developments

After 2014, Cicada 3301 largely vanished as suddenly as it appeared, but its impact and legend live on. The legacy of Cicada 3301 can be seen in both internet culture and in the ongoing curiosity it inspires:
An Unsolved Legend: Today, Cicada 3301 is frequently cited as one of the eeriest unsolved mysteries of the internet. The fact that no one has publicly identified the creators or purpose of these puzzles gives it an almost mythic status.
It’s often compared to other famous mysteries like the Voynich Manuscript or the Kryptos sculpture, or puzzles that tease with the possibility of a hidden truth, remaining just out of reach.
Enthusiast communities still exist; for example, there are wiki pages and Discord servers where dedicated fans continue to analyze the clues and especially to work on decoding the remaining pages of the Liber Primus, hoping to one day reveal the final message.
In a real sense, the Cicada puzzle isn’t completely “over” because parts of it (like Liber Primus) have not been solved. This means the door is always open for new sleuths to try their hand at it, keeping the mystery alive year after year.
Final Messages and Silence: The last known official communication from Cicada 3301 came in April 2017, in the form of a PGP-signed message (using the same cryptographic signature Cicada had used all along to verify its identity).
In that message, Cicada 3301 warned the public about “unauthorized third parties” trying to use the name Cicada 3301 without permission, and stated that any puzzle not signed with their official PGP key should be considered suspect. Essentially, they were saying “if it’s not cryptographically signed by us, it’s not us.”
This was likely in response to various copycat puzzles and hoaxes that had started to appear, as fans or opportunists tried to continue the Cicada tradition on their own. After this 2017 signed message, there have been no new verified puzzles or communications from the original Cicada 3301 group.
The trail has gone cold. The Twitter account went quiet. To the best of public knowledge, Cicada 3301 disbanded or went completely dark after 2017. All we have are the puzzles and clues they left behind and a lot of unanswered questions.
What Was Cicada 3301, Really? Without official answers, people have continued to speculate about who was behind Cicada and what their goal was. Over the years, a few clues and rumors have trickled out from alleged insiders.
For example, some self-claimed winners or leakers suggested that Cicada 3301 was not a government agency at all but rather a small group of privacy-minded enthusiasts (perhaps around 20 individuals) who wanted to develop and promote cryptographic software for the public good.
According to this rumor, the puzzles were a way to find talented people who believed in ideals like internet freedom and privacy, and recruit them to work on secret projects (such as creating secure communication tools resistant to censorship).
This aligns with what known winners have said: those who solved the puzzles in 2012–2013 reported that they were asked about their stance on information freedom and were tasked with projects to advance those ideals. In other words, Cicada might have been a grassroots movement to strengthen privacy and security technology by gathering sharp minds.
However, it’s important to note that none of these theories have been confirmed. The “small privacy group” explanation is just one of many. Other theories persist that perhaps it really was a clever recruitment program for an intelligence agency or corporation (who have never admitted it), or that it was an elaborate social experiment or game that ended once it proved its point.
Influence on Culture and Copycats: Cicada 3301’s influence can be seen in various places. For one, it inspired similar puzzles and challenges. Notably, in 2014 the U.S. Navy created a cryptographic recruiting game called Project Architeuthis, clearly modeled after Cicada’s style (Architeuthis is the Latin name for a giant squid, a wink to Cicada).
Cicada has also been referenced or inspired plotlines in popular media. A 2014 episode of the TV show Person of Interest featured a large-scale mysterious game called “Nautilus” that was directly inspired by Cicada 3301.
More recently, in 2021 a comedy-thriller film titled “Dark Web: Cicada 3301” was released, which is a fictional story built around the concept of the Cicada puzzle, showing how it has entered the public imagination.
Beyond these, Cicada 3301 has become part of internet folklore; even people who never attempted the puzzle sometimes recognize the cicada emblem or the number 3301 as shorthand for “that crazy internet puzzle thing.” It has been the subject of countless YouTube videos, articles, and discussions in the years since it appeared.
The legacy of Cicada 3301 blended technology, art, and adventure in a way that had never quite been done before. And it left us with a haunting question: what was it all for?
As of 2025, the Cicada 3301 mystery remains unsolved in the sense that the organization’s true identity and purpose have never been publicly revealed.
The puzzles stopped, but they left a trail of breadcrumbs that intrepid codebreakers are still picking over. Maybe one day someone will decrypt the final pages of Liber Primus or an insider will come forward with the full story.
Or perhaps Cicada 3301 will unexpectedly return with a new puzzle, as challenging and beguiling as the last. Until then, it remains an open case; a modern legend of the digital age, where each answer only led to new questions.
And for all of us who love a good mystery, Cicada 3301 is a reminder that the internet still has a few secrets left up its sleeve.
