Cipher Hunt

The Cipher Hunt was an alternate reality game and international scavenger hunt created by storyboard artist and voice actor Alex Hirsch based on his animated series Gravity Falls. The goal was to find the real-life statue of the series' antagonist Bill Cipher, which was briefly glimpsed at the end of the series finale. The hunt involved retrieving and decoding clues hidden in various locations worldwide.

The Cipher Hunt began on July 20, 2016, in Saint Petersburg, Russia, and concluded on August 2, 2016, in a forest in Reedsport, Oregon, where the statue was found. The statue was later taken by local authorities due to a property dispute and was temporarily displayed at Bicentennial Park in Reedsport, before it was relocated permanently to Confusion Hill, a roadside attraction in Piercy, California.

Creation
In the Gravity Falls behind the scenes documentary One Crazy Summer, which was included as a special feature in the Gravity Falls: The Complete Series collector's edition DVD box set released by Shout! Factory, series creator Alex Hirsch discussed the origins of the Cipher Hunt. As Gravity Falls is a show about mystery, Hirsch wanted to give fans one final mystery that no one was expecting and that no show had ever done before. He very quickly came up with the idea of sending fans on a worldwide treasure hunt for a real life Bill Cipher statue. Hirsch recruited the show's art director Ian Worrel to assist him with planning out the hunt. Worrel designed a spreadsheet of all of the locations that would be used in the hunt. Hirsch got a friend of a friend of his, Fon Davis, a prop fabricator for movies and a judge on the ABC robot combat game show BattleBots, to design and build a statue of Bill Cipher out of plexiglass, as it's made to withstand the elements. They rubbed glue with seeds in it on the statue, so that it would start to grow moss and look like it had been in the woods for years. Hirsch then took a trip to Reedsport, Oregon and found a woman who was willing to let him install a statue on her property that people would hunt for. They then drove the statue up to Reedsport, installed the statue in the ground, and recorded a few seconds of footage of the statue to insert into the end of Gravity Falls ' series finale, "Weirdmageddon 3: Take Back the Falls". After the finale aired on Disney XD on February 15, 2016, Hirsch took a trip to a couple of conventions and vacation spots and he would secretly leave behind a clue for the hunt at every place he visited.

Starting phase
Fans of Gravity Falls started speculating that a real-life statue of Bill Cipher exists somewhere in the world based on the end of the series' final episode, which contained both the brief clip of the Bill Cipher statue and an encoded riddle hinting at the presence of buried treasure "deep within the woods" and a statue "beyond the rusty gates". Both Hirsch and the show's team did not talk about the presence of a statue in the months following the show's end until July 20, 2016, when Hirsch tweeted "Are you guys ready?" and began the hunt with a tweet containing the words "Let the games begin #FLSKHUKXQW" and an image that contained several cryptograms and clues. When decoded, the aforementioned hashtag translates to "#CIPHERHUNT". The image featured two paragraphs of coded riddles with a few red letters mixed in. Between the paragraphs is the Bill Cipher statue surrounded by various trees with branches and knots. Above the statue is a banner with some numbers that when decoded with the A1Z26 Cipher spells "PINES". Above the banner is a diagram of architectural plans for the location of the first clue. The top left corner of the image is ripped off.

Hirsch also posted the rules of the hunt on Twitter, which clarified that the hunt was an unofficial self-made tribute, unaffiliated with any company, including the Walt Disney Company, which owns the rights to Gravity Falls. He also asked fans to be careful and to avoid trespassing and/or vandalism, since most of the clues' locations were in public areas. Fans utilized social media outlets such as Twitter, Tumblr, Periscope, and Reddit to communicate and share their findings.

First clue: Saint Petersburg, Russia
After the hunt's announcement, the location of the hunt's first clue was hinted to be in Russia, after the series of red letters printed in the tweeted image was decoded using a −3 Caesar cipher and an Atbash cipher creating the country's name, which Hirsch visited for a convention in April 2016. Russian fans of the show recognized the diagram at the middle left of the image as an architectural plan of the Kazan Cathedral in Saint Petersburg. Using a diagram at the middle right of the image which showed the first clue's exact location inside the cathedral, it was successfully found.

Second clue: Tokyo, Japan
After the text on the first clue was decoded, it pointed to the second clue being located in Japan as the text mentioned a "shrine" and "yen", the latter of which is the country's official currency. The text also mentioned a "sword" and "crescent" marking the clue. The second clue was located at the Kanda Shrine in Chiyoda, Tokyo, which Hirsch and his partner Dana Terrace visited during their trip to the country in February 2016. The clue was written on the back of one of the emas in the shrine with a drawing of a scimitar and crescent, along with an encrypted message.

Third clue: Atlanta, Georgia
The decoded text on the second clue pointed to the next clue being in the United States at 400 Ponce de Leon Avenue NE in Atlanta, Georgia as the second clue contained the words "...the hunter of the fountain of youth. 400 before his name is written...", with the first phrase describing the avenue's namesake, Spanish explorer Juan Ponce de León. The address found led to a Shriners' temple. The text on the second clue also mentioned finding something "LOST". This led community streamers to find a lost poster for Waddles, Mabel Pines's pet pig, in the area, which was water damaged and difficult to read. The poster contained a picture of and information about Waddles, a cryptogram, and a phone number to call if Waddles was found. When called, the phone number plays a backwards message, which, when reversed, played a message from one of the show's main characters, Grunkle Stan, with the theme song for the science fiction television series The X-Files playing in the background.

Fourth and fifth clue: Los Angeles, California
The recorded phone message revealed that the fourth clue's location was in the Ochre Court building of Salve Regina University in Newport, Rhode Island. The clue was supposed to be located behind a portrait of Mary Hilda Miley, the university's second president. However, the university accidentally disposed the clue before the hunt began. Hirsch then promised to give a replacement clue and asked fans to stay out of the university in the meantime.

On July 21, 2016, at 12:30pm PST, Hirsch tweeted a phone number, the same one on Waddles' missing poster in Atlanta. When called, the phone number played a new message from Grunkle Stan, which revealed that the next clue was located near the statue of Griffith J. Griffith at Griffith Park in the Los Feliz neighborhood of Los Angeles, California. A golden head of Grunkle Stan was found with an encoded message written in invisible ink on three sheets of paper, as well as an invisible ink pen to read the message.

The decoded text from the fourth clue showed that the fifth clue was located in Century City, another neighborhood in Los Angeles, at a park between the Century Plaza Towers and the Creative Artists Agency building, notably trimmed into the shape of the Eye of Providence. Fans were joined by Gravity Falls cast member Jason Ritter and Alex Hirsch's twin sister, Ariel Hirsch in the hunt. A black pouch was found containing a USB stick with a drawing of Bill Cipher on it. The USB stick contained an audio file that was later uploaded to SoundCloud. The recording featured Grunkle Stan being taunted by the ghost of Sister Mary Hilda Miley (a reference to the disposed clue at Salve Regina University) about not finding the treasure, with music and sound effects from the 1990 video game Super Mario World in the background.

Sixth clue: Santa Clarita, California
The fifth clue explicitly revealed the sixth clue's location, which was at the campus of the California State Summer School for the Arts, located inside Hirsch's alma mater, the California Institute of the Arts in Santa Clarita, California. It also said that the clue can only be accessed by students of the campus. The sixth clue was accidentally discovered by a student in the campus' sublevel in the form of a graffiti on a wall a week before the Cipher Hunt began. The graffiti shows a crudely drawn Bill Cipher and a series of hexadecimal to decimal codes.

Seventh clue: Piedmont, California
The decoded hex codes from the sixth clue form co-ordinates that led to Piedmont, California, the hometown of both the Pines and Hirsch twins. The cryptogram on the Waddles missing poster found in Atlanta, as well as some guidance from Hirsch, led fans to a pink key tied to a tree stump in Piedmont Park, in addition to a small chest with a cryptex locked behind a five-letter keyword. The keyword used to open the cryptex was "PINES", which can be found on the banner above the Bill Cipher statue on the initial Cipher Hunt image tweeted by Hirsch.

Eighth clue: Los Angeles, California
Using the keyword from the original image, the cryptex from the seventh clue was opened, revealing another key and the next clue, which showed that the eighth clue was located at a USPS post office at 1825 N Vermont Avenue in Los Angeles, California and the provided key was to be used to open a PO box that contained the eighth clue.

After an eight-hour drive, the person with the key made it to the PO box and used the key to open it. The eighth clue was a plastic bag containing two thousand jigsaw puzzle pieces, a note with Bill Cipher drawn on it, that when decoded translates to "I HOPE YOU LIKE PUZZLES!", and 37 fake dollars (known as Stan Bucks) which included the word "FILBRICK" written on the back of each one in invisible ink. Fans almost immediately got stuck on the puzzle. After two days, during which some took sleep shifts while some did not sleep at all, they managed to complete scattered portions of the puzzle that show what it contained, which was Bill Cipher with a gnome under him and letters in a cryptogram below him and to his sides.

After another day, Hirsch tweeted an image which showed a rough idea of what the completed puzzle should look like, but with a different code that translated to "THIS IS WHERE THE CLUE WILL APPEAR". After two more days, Hirsch tweeted two images of different coded sections of the puzzle. Fans used Adobe Photoshop to piece these two images together and then decoded what they could make out. Additionally, a virtual version of the puzzle was created and uploaded to the internet by fans working on the physical puzzle to get some help. Within a few hours, the coded message on the puzzle was then digitally solved by a group effort of fans working together online.

Ninth clue: Portland, Oregon
While progress on the puzzle was still ongoing, a fan discovered the next clue by complete accident. He was walking on the corner of Rodney Avenue and Tillamook Street in Portland, Oregon where he spotted a lawn gnome. Having been keeping up with the hunt on Twitter and knowing that the puzzle contained a small image of a lawn gnome, he decided to pick up the gnome on a whim only to find a View-Master and the ninth clue written on a crumpled up piece of paper underneath it.

Though the clue was found without completing the puzzle, Hirsch provided an incentive to those who are in the process of completing both the physical and virtual puzzles by saying that if the physical puzzle got finished, he would release the unaired pilot episode of Gravity Falls made in 2010 and if the virtual puzzle got finished, he would upload unreleased cut scenes from the show. The physical puzzle was completed on August 1. Hirsch showed up upon its completion, signed it and promised the release of the original pilot.

Tenth clue: Piercy, California
The View-Master from the ninth clue contained slides depicting the area around Confusion Hill in Piercy, California, a tourist trap similar to the Mystery Shack, Grunkle Stan's business in the series. One of the slides also contains an image of Snoqualmie Falls in Washington, a waterfall known for appearing in the television series Twin Peaks, an inspiration to Gravity Falls. This pointed to the tenth clue being located at Confusion Hill.

The ninth clue mentioned a "gift shop" and using a "password" to buy an "eyeball jar". A fan went to the gift shop at Confusion Hill, but needed to know a certain password to buy a jar containing fake eyeballs which was located behind the register. The password was "FILBRICK," the word written in invisible ink on the back of the fake money (known as Stan Bucks) packaged with the jigsaw puzzle. Using the password, the fan retrieved the eyeball jar and found the tenth clue written on the bottom of it. Additionally, Hirsch stated that fans will receive a prize if they take a selfie with the framed photo of the Gravity Falls crew at Confusion Hill. The framed photo is from a different Gravity Falls event called "Mystery Tour 2013".

Eleventh clue: Amity, Oregon
The tenth clue pointed to the eleventh clue's location, which was at Stanley Street in Amity, Oregon, near a pair of telephone poles. The tenth clue also mentioned the word "bolt" which was underlined. A group of fans went to the street as instructed and found a geocache bolt, which they somehow lost before finding it again. They unscrewed it to find the eleventh clue inside, written double-sided on a very narrow strip of paper.

Twelfth and final clue: Turner, Oregon
The twelfth clue was found at the Enchanted Forest amusement park in Turner, Oregon, as the eleventh clue mentioned Roger Tofte, the creator of the amusement park. The eleventh clue also mentioned that the next clue was located "behind a sign, buried at the base" and "near Pa's laundry on a hill". A family raced to Enchanted Forest in pursuit of the clue and dug around in the dirt at the base of a sign that reads "Here lies the bones of a man named Bill" which was located near Pa's laundry shop, but found nothing. Hirsch eventually realized that the clue was already taken by another fan before the family got there. The fan uploaded the image of the twelfth clue online, which was a ripped piece of paper that contained an encoded riddle. The riddle told fans to "return to where it all began" and "the answers written in the trees".

The twelfth clue was revealed to be the final clue, with the next stop in the hunt being the location of Bill Cipher's statue. On the back of the final clue, there was a dotted red line leading to an X, as if it was a treasure map. This dotted line can be combined with the dotted red line found on the initial Cipher Hunt image posted by Hirsch on Twitter, revealing that the final clue is the ripped off top left corner of the image. Fans used the initial image and final clue combined to search for the statue in several locations across the West Coast with no results. Meanwhile, many people made unsuccessful attempts to find an encoded message in the trees seen behind Bill's statue in the image.

Reedsport, Oregon
After several days with no progress and asking fans on Twitter if they wanted it, Hirsch tweeted a hint for the final clue, which revealed that a Polybius square was needed to solve the clue. Fans also needed to find a pattern in the branches and knots of the trees in the image that could be converted to pairs of numbers, as well as finding out which specific version of the Polybius square was used to encode the message. Through clever cryptoanalysis of the branches and knots, and by manipulating the possible results with the assumption that the decoded message was a location that had to end with the letters "OR" (the abbreviation for Oregon), a "reverse" code cracking method was used. The most likely resulting message was "REEDSPORTOR," so the fans were able to narrow down the location of the statue to Reedsport, Oregon. Hirsch retweeted messages of fans that were heading there, reinforcing the assumption. The treasure map found on the back of the twelfth clue was assumed to be a map through the city's parks or surrounding forests to find the statue, so the fans searched in Google Maps for a path where the map fitted, locating one at the end of S 22nd Street, south of Reedsport Community Charter School. The complete code was cracked later that evening confirming the message to be "REEDSPORTOR".

Fans quickly raced to the city to be the first to find the statue of Bill Cipher. The statue was found on August 2, 2016, at 7:53pm PDT by Twitter user @shadow_wolfwind (who changed her Twitter handle to @OfficialGFMayor following the hunt), who tweeted a photo of it. Later, a treasure chest buried in front of the statue was found and dug up by other fans, with several of them shaking the statue's hand, including a baby.

The treasure chest contained a wide array of loot, such as plastic coins and gems, Russian and Japanese currency, a copy of the book Gravity Falls: Journal 3 which was signed and contained a special drawing by Hirsch himself, a black light flashlight, a plastic crown, a sash that says "Mayor of Gravity Falls," a music box with Bill Cipher's eye drawn on it that plays the show's theme song, a slip of paper with a message written by Hirsch in invisible ink, a miniature Bill Cipher statue, a framed sketch of the main characters standing with the statue, and a USB drive. Some currency in the chest was marked by a person named Bradley who had found the treasure a month before the hunt began.

The USB drive contained a text document that contains a link to Bradley's Twitter account, an audio file of Grunkle Stan singing the song "We'll Meet Again" and congratulating the finders, and another text document entitled "MyExWifeStillMissesMe.ButHerAimIsGettinBetter," which, when opened in Microsoft Notepad, a text reading "RETURNBACKWARDSTOTHEPASTAGAINTHREE" appears. When "RETURNBACKWARDS" and "TOTHEPASTAGAINTHREE" are entered as a username and password respectively on the website themysteryofgravityfalls.com/pilot, it would allow users to watch the unaired pilot episode of Gravity Falls, which is a prototype of "Tourist Trapped", the series' first episode, made with an entirely different art style and some altered dialogue and scenes.

Aftermath
On August 3, a day after Bill Cipher's statue was found, the statue and its treasure were taken by local authorities because of a property conflict between the apparent proprietor who had authorized Hirsch to place the statue and another person claiming ownership of the land where it was located. Its hat was broken in the process, though it had already sustained damage. Reedsport Police ended up holding the statue at the Reedsport police department, keeping it intact, while Hirsch arranged for it to be moved somewhere else. By August 5, the statue ended up in Reedsport's Bicentennial Park, where it was bolted to the top of a tree above the ground, lacking its hat. The treasure box was placed beneath the statue. Fans continued to visit the statue.

On August 15, Hirsch called for volunteers to relocate Bill's hat and to move the statue via truck to a new location. Three days later, on August 18, the statue had been removed from Bicentennial Park with a sign in its place that read "BILL WAS HERE", when decoded through a substitution cipher. On August 19, Twitter user @Knarkill34 tweeted that they had moved the statue to an undisclosed location, but provided pictures. On August 20, several fans discovered that the statue was moved to Confusion Hill in Piercy, California. The statue acquired a new hat within a week, and the treasure box was not transported to the attraction. The statue and the completed physical puzzle are both currently housed at Confusion Hill, along with a special treasure cache where fans have since taken and left treasures for fellow fans who wish to visit the statue.

Deleted scenes from Gravity Falls, which were promised during the hunt, were released as part of the Gravity Falls: The Complete Series DVD box set.

Numerous online media outlets have reported on the hunt and its progress, including Atlas Obscura, The Daily Dot, io9, and Odyssey.

Bradley
Although Twitter user @shadow_wolfwind, the recipient of the "Mayor of Gravity Falls" sash stored in the treasure chest, is the first official person to have found the Bill Cipher statue, the chest also contained Stan Bucks that have been signed by a person named Bradley Pic who found the statue on July 12, eight days prior to the start of Cipher Hunt, making him the actual first person to find it.

During an appearance on the Mystery Shack Lookback Podcast in July 2022, Alex Hirsch revealed the full story behind what happened and how Bradley's name ended up in the chest. Bradley was a resident of Reedsport, Oregon who accidentally found the statue while going out for a walk one day. According to Hirsch, this was shortly after he had placed the statue in its location as Gravity Falls had not yet ended. Bradley had never heard of the show, but posted an image of the statue to an unsolved mysteries subreddit, though the post did not gain much attention. However, the person behind the @TheMysteryofGF Twitter page managed to find the post, and being in the know about the Cipher Hunt, contacted Hirsch about it. Knowing the hunt could be ruined if the post was found by fans, Hirsch was able to get in touch with Bradley and informed him about what the statue was and asked him to take the post down. In exchange for taking it down and his silence about the statue and its location, Hirsch paid Bradley $100, gave him a prize and allowed him to take the credit for finding the statue after Cipher Hunt was over.

Before the hunt started and after being paid off by Hirsch, Bradley returned to the statue, dug up the treasure chest, signed his name on the money inside it and left a text file on the USB drive named "Hi.txt" which contained a link to his Twitter account. He would later upload a video of him finding the statue to help answer questions fans had about why his name and link to his Twitter account were in the treasure, however, the full story would not be revealed until 2022 by Hirsch.
