In South Korea, Seong Gi-hun, a divorced father and indebted gambling addict who lives with his elderly mother, is invited to play a series of children's games for a chance at a large cash prize. Accepting the offer, he is taken to an unknown location where he finds himself among 455 other players who are all in deep financial trouble. The players are made to wear green tracksuits and are kept under watch at all times by masked guards in pink jumpsuits, with the games overseen by the Front Man, who wears a black mask and black uniform. The players soon discover that losing a game results in their deaths, with each death contributing ₩100 million (US$87,400) to the potential ₩45.6 billion (US$39.86 million) grand prize.^[a][b] Gi-hun allies with other players, including his childhood friend Cho Sang-woo and North Korean defector Kang Sae-byeok, to try to survive the games' physical and psychological twists, while detective Hwang Jun-ho infiltrates the games as one of the guards to find his missing brother.^[11][12]

In the second season, Gi-hun, who had vowed revenge three years after winning the game, participates in it again to take revenge on the Front Man and end the game for good, and is joined by police detective Jun-ho, the Front Man's brother. After assuming full control of the game following the creator Il-nam's death, the Front Man attempts to make Gi-hun see that there is no way he can end the games due to the true nature of people.^[13] Gi-hun will start to play the next Squid Game. Gi-hun allies with other players, including his best friend Park Jung-bae and a pregnant girl Kim Jun-hee, to try to survive the games' physical and psychological twists, while detective Hwang Jun-ho and Choi Woo-seok must find the Island while Kang No-eul begin to work as a Squid Game Guard.

In the third and final season, Gi-hun and the players fight for survival in ever-deadlier games, which have dire consequences. In-ho welcomes the VIPs while his brother Jun-ho continues the search for the island, unaware of a traitor in their midst.

Around 2008, Hwang Dong-hyuk tried unsuccessfully to get investment for a different movie script that he had written, and he, his mother, and his grandmother had to take out loans to stay afloat, but still struggled amid the debt crisis within the country.^[9][38][f] He spent his free time in a manhwabang (South Korean comic cafe) reading Japanese survival manga such as Battle Royale, Liar Game and Gambling Apocalypse: Kaiji.^{[40][41][8][42]} Hwang compared the characters' situation in these works to his own current situation and considered the idea of being able to join such a survival game to win money to get him out of debt, leading him to write a film script on that concept throughout 2009.^[42] Hwang stated, "I wanted to write a story that was an allegory or fable about modern capitalist society, something that depicts an extreme competition, somewhat like the extreme competition of life. But I wanted it to use the kind of characters we've all met in real life."^[43] Hwang feared the storyline was "too difficult to understand and bizarre" at the time.^[40] Hwang tried to sell his story to various South Korean production groups and actors, but had been told it was too grotesque and unrealistic.^[44] Hwang put this script aside and over the next ten years successfully completed three other films. including the crime drama film Silenced (2011) and the historical drama film The Fortress (2017).^[42]

In the 2010s, Netflix had seen a large growth in viewership outside of North America, and started investing in productions in other regions, including South Korea.^[45] In 2018, Ted Sarandos, co-CEO of Netflix, stated that they were looking for more successes from overseas productions: "The exciting thing for me would be if the next Stranger Things came from outside America. Right now, historically, nothing of that scale has ever come from anywhere but Hollywood."^[46] Netflix had opened up a division in Asia in 2018, and while they were still operating out of temporary leased office space in Seoul, Hwang brought his script to their attention. Kim Minyoung, one of Netflix's content officers for the Asian regions, recognized Hwang's talent from The Fortress and his other films, and upon seeing his script for Squid Game, knew they needed it for the service. Kim said "[W]e were looking for shows that were different from what's traditionally 'made it,' and Squid Game was exactly it".^[47] In September 2019 Netflix formally announced that they would produce Hwang's work as an original series.^[44][48] Netflix's Bela Bajaria, head of global television operations, said of their interest in Hwang's work that "we knew it was going to be big in Korea because it had a well-regarded director with a bold vision", and that "K-Dramas also travel well across Asia".^[45] Regarding his return to the project, Hwang commented, "It's a sad story. But the reason why I returned to the project is because the world 10 years from then has transformed to a place where these unbelievable survival stories are so fitting, and I found that this is the time when people will call these stories intriguing and realistic."^[40] Hwang further believed that the COVID-19 pandemic impacted the economic disparity between classes in South Korea, and said that "All of these points made the story very realistic for people compared to a decade ago".^[44]

With the Netflix order, the film concept was expanded out to a nine-episode series. Kim stated that there was "so much more than what was written in the 120-minute format. So we worked together to turn it into a series."^[47] Hwang said he was able to expand the script so that it "could focus on the relationships between people [and] the stories that each of the people had".^[49] Initially, Netflix had named the series Round Six, rather than Squid Game as Hwang had suggested; according to Netflix's vice president for content in Asia Kim Minyoung, while they knew that the name "squid game" would be familiar to Korean viewers from the children's game, it "wouldn't resonate because not many people would get it", and opted to use Round Six (stylized as Round 6) as it self-described the nature of the competition. It has been titled as such in Brazil (possibly while also avoiding any political connotation to do with Lula). As production continued, Hwang pushed on the service to use Squid Game instead; its cryptic name and unique visuals helped to draw in curious viewers, according to Kim.^[48][50] At the time that Hwang wrote the series, his goal was to have the series reach the most-watched show in Netflix in the United States for at least one day.^[9] Hwang had initially written the series as eight episodes, which was comparable to other Netflix shows, but found that the material for the last episode was longer than he planned, so it was split into two.^[51]

In late October 2021, Hwang stated he was in discussions with Netflix regarding a second season.^[9] He further stated in December 2021 that he was also discussing a third season with Netflix.^[52] Hwang wanted to produce another film first, as well as secure a contract with Netflix to release additional films he may create alongside further Squid Game seasons, so as to avoid becoming known only for Squid Game.^[9] Hwang confirmed that he had begun conceptualization work on a second season during a press event in November 2021, with plans to bring back Lee Jung-jae to reprise his role of Gi-hun.^[53] Netflix stated in response to Hwang's comments that they had not yet officially greenlit a second season, but were in discussions with Hwang towards one.^[54] During an earnings call in January 2022, Netflix's Sarandos said when asked about a second season "Absolutely...the Squid Game universe has just begun."^[55][56][57] Hwang said in April 2022 that he presently was working on Killing Old People Club, an adaption of a work called "Pape Satan Aleppe: Chronicles of a Liquid Society" by Umberto Eco (미친 세상을 이해하는 척하는 방법; "The way to pretend to understand the crazy world"), and anticipated that the second season of Squid Game would be completed and broadcast by 2024.^[58] Netflix confirmed that the second season was greenlit in June 2022.^[59][60] It was released on December 26, 2024.^[61]

On the day the second season was released, Hwang confirmed that the series would return for a third and final season in 2025.^[62] The season was released on June 27, 2025.^[63]

Hwang described the work as "a story about losers".^[64] The names of the characters – Seong Gi-hun, Cho Sang-woo, and Il-nam – were all based on Hwang's childhood friends, as well as the character name Hwang Jun-ho, who was also a childhood friend in real life with an older brother named Hwang In-ho.^[42] The two main characters Gi-hun and Sang-woo were based on Hwang's own personal experiences and represented "two sides" of himself; Gi-hun shared the same aspects of being raised by an economically disadvantaged single mother in the Ssangmun district of Seoul, while Sang-woo reflected on Hwang having attended Seoul National University with high expectations from his family and neighborhood.^[42][64] Further, Gi-hun's background was inspired by the organizers of the SsangYong Motor labor strike of 2009 against mass layoffs.^[65]

Hwang based the narrative on Korean games of his childhood to show the irony of a childhood game where competition was not important becoming an extreme competition with people's lives at stake.^[41] Additionally, as his initial script was intended for film, he opted to use children's games with simple rules that were easy to explain in contrast to other survival-type films using games with complex rules.^[49] The central game he selected, the squid game, was a popular Korean children's game from the 1970s and 1980s.^[48][66] Hwang recalled the squid game as "the most physically aggressive childhood game I played in neighborhood alleys as a kid, which is why I also loved it the most", and because of this "it's the most symbolic game that reflects today's competitive society, so I picked it out as the show's title".^[67] The colors of the ddakji in the initial game, which are blue and red, were inspired from the Japanese urban legend Red Paper, Blue Paper.^[68][g] The game Red Light, Green Light was selected because of its potential to make a lot of losers in one go. Regarding the selection, Hwang said, "The game was selected because the scene filled with so many people randomly moving and stopping could be viewed as a ridiculous but a sad group dance."^[41] Hwang joked that the dalgona candy game they chose may influence sales of dalgona, similar to how sales of Korean gats (traditional hats) bloomed after the broadcast of Netflix's series Kingdom.^[69] Licking the candy to free the shape was something that Hwang said that he had done as a child and brought it into the script.^[67] Hwang had considered other Korean children's games such as Gonggi, Dong, Dong, Dongdaemun, and Why did you come to my house? (우리 집에 왜 왔니?, a Korean variant of the Hana Ichi Monme).^[41]

Hwang wrote all of the series himself, taking nearly six months to write the first two episodes alone, after which he turned to friends to get input on moving forward.^[43] Hwang also addressed the challenges of preparing for the show which was physically and mentally exhausting, saying that he had forgone dental health while making Season 1 and had to have six teeth pulled by his dentist after production was complete.^[40][51] As such, Hwang was initially unsure about a sequel after completing these episodes,^[43] though he wrote the ending to keep a potential hook for a sequel in mind.^[9] Hwang had considered an alternate ending where Gi-hun would have boarded the plane after concluding his call with the game organizers to see his daughter, but Hwang said of that ending, "Is that the right way for us to really propose the question or the message that we wanted to convey through the series?"^[70]

Due to the stress of writing and producing the first series of nine episodes himself, Hwang initially had no immediate plans to write a second season to Squid Game. He did not have well-developed plans for a follow-up story and said that if he were to write one, he would likely need a staff of writers and directors to help him.^[43] With the immense popularity of the show, Hwang later opined about the possibility of a second season, telling CNN, "There's nothing confirmed at the moment, but so many people are enthusiastic that I'm really contemplating it."^[64] Hwang said in an interview with The Times that a second season may focus more on the story of the Front Man as well as incorporating more about the police. Hwang said, "I think the issue with police officers is not just an issue in Korea. I see it on the global news that the police force can be very late in acting on things—there are more victims or a situation gets worse because of them not acting fast enough. This was an issue that I wanted to raise."^[71] He added he also wanted to explore the relationship between the cryptic Front Man and his policeman brother Hwang Jun-ho, as well as the background of the salesman character (portrayed by Gong Yoo).^[72]

Hwang originally envisioned the second and third seasons as one, but split them up because he had too many episodes for one season.^[73] According to Hwang, after the end of the second season, Gi-hun would be a changed man "at a very critical crossroads".^[74] The season will also reveal how Hwang In-ho became the Front Man.^[75] Cheol-su, Young-hee's giant robot doll boyfriend, was introduced at the end of the second season and appeared in the third season alongside a new game.^[76]

Director Hwang requested that actors Gong Yoo (left) and Lee Byung-hun (right), with whom he had previously worked, appear as the Recruiter and the Front Man, respectively, in Squid Game.

Hwang said he chose to cast Lee Jung-jae as Gi-hun as to "destroy his charismatic image portrayed in his previous roles".^[77] HoYeon Jung was requested by her new management company to send a video to audition for the series while she was finishing a shoot in Mexico and preparing for New York Fashion Week. Although this was her first audition as an actor and her expectations were low, Hwang said, "The moment I saw her audition tape from New York, I immediately thought to myself, 'this is the girl we want.' My first impression of her was that she is wild and free like an untamed horse".^[78][79][80] On casting Anupam Tripathi as Ali Abdul, Hwang said, "It was hard to find good foreign actors in Korea." He chose Anupam Tripathi because of his emotional acting capabilities and fluency in Korean.^[81] Both Gong Yoo and Lee Byung Hun had worked with Hwang during his previous films, Silenced and The Fortress respectively, and Hwang had asked both to appear in small roles within Squid Game.^{[78][unreliable source?]} The VIPs were selected from non-Korean actors living in Asia; in the case of Geoffrey Giuliano, who played the VIP that interacted with Jun-ho, his prior role from Train to Busan Presents: Peninsula led to his casting for Squid Game.^[82]

Casting for the series was confirmed on June 17, 2020.^[83]

In April 2022, Hwang confirmed that the characters of Gi-hun and the Front Man will return for the second season.^[84][59] Hwang said that he would like to bring back some of the dead characters, such as Ji-yeong, and expressed regret that he had killed off several beloved characters since he did not have any plans for a second season at that time.^[85]

During Netflix's Tudum: A Global Fan Event in June 2023, Lee Jung-jae was confirmed to reprise his role alongside Lee Byung-hun, Gong Yoo and Wi Ha-joon. On June 29, Netflix released more info on the new season's cast, which includes Kang Ha-neul, Park Sung-hoon, Im Si-wan, Yang Dong-geun, Park Gyu-young, Lee Jin-wook, Won Ji-an, Jo Yu-ri, Kang Ae-shim, Lee David, and Roh Jae-won.^[86][23][22] Controversy arose when it was revealed that T.O.P, a former member of the band BigBang with a drug-related conviction during military service in 2016, was cast in the second season.^[87]

Squid Game – Behind the Scenes, from Netflix

Production and filming of the series ran from June to October 2020, including a mandatory month-long break due to the COVID-19 pandemic.^[88] City scenes were filmed in Daejeon,^[89] while the island set pieces were filmed on Seongapdo located in Ongjin.^[90]

As Netflix was targeting the work for a global audience, the visuals were emphasized and some of the rules of the children's games were simplified to avoid potential issues with the language barrier.^[44] The colorful sets and costumes were designed to look like a fantasy world. The players and soldiers each wear a distinctive color, to reduce the sense of individuality and emphasize the difference between the two groups.^[41] The green tracksuits worn by the players were inspired by 1970s athletic wear, known as trainingbok (트레이닝복).^[91] The maze-like corridors and stairs drew inspiration from the 4-dimensional stair drawings of M. C. Escher including Relativity. Production designer Chae Kyoung-sun said these seemingly infinite stairways represented "a form of bondage for the contestants".^[92] The complex network of tunnels between the arena, the dorm, and the administrative office was inspired by ant colonies.^[41]

Chae was also inspired by the Saemaul Undong political initiative of the 1970s aimed to modernize rural South Korean villages.^[93] The mint green and pink color theme throughout the show were a common theme from South Korean schools in the 1970s and 1980s. Green-suited characters develop associations of fear with pink through its use in guard outfits and the stairway room.^[94][92]

The players' dormitory was envisioned with the concept of "people who are abandoned on the road" according to Chae; this was also used in the tug-of-war game.^[94] The room was designed using white tiles and the curved opening like a vehicular tunnel. The bed and stairs initially were laid out to look like warehouse shelves, but as the episodes progressed and these furnishing used as makeshift defenses, they took the appearance of broken ladders and stairs, implying the way these players were trapped with no way out, according to Chae.^[94] The dinner scene that took place in the eighth episode was inspired by the art installation The Dinner Party by Judy Chicago.^[92] Walls of many of the areas where the games took place were painted in skies inspired by The Empire of Light series by René Magritte.^[92]

The crew spent the most time crafting the set for the Marbles game, creating a mix of realism and fakeness as to mirror the life and death nature of the games themselves.^[95] Chae stated that this set was designed as a combination of small theatrical stages, each stage representing parts of Player 001's memories.^[94] The VIP room was one of the last pieces to be designed, and Chae said that they decided on an animal-based theme for both the costumes and room for this; "The VIPs are the kind of people who take other people's lives for entertainment and treat them like game pieces on a chessboard, so I wanted to create a powerful and instinctive look for the room."^[94]

Most sets were a combination of practical sets and chroma key backgrounds. For example, in the Glass Stepping Stones scenes, the set, designed as if in a circus tent for the players performing for the VIPs, was only 1.5 metres (4.9 ft) off the ground, using chroma key screens to simulate the height in post-production. In filming, this was far enough from the ground to make the actors nervous, which contributed to the scene.^[95][94] The tug-of-war set was actually set more than 10 metres (33 ft) off the ground, which further created anxiety for some of the actors with fears of heights.^[94]

The robot doll in the first episode, "Red Light, Green Light", was inspired by Younghee, a character who appeared on the covers of South Korean textbooks Chul-soo and Young-hee in the 1970s and 1980s,^[92] and her hairstyle was inspired by Hwang's daughter's.^[91][94] The doll singsongs, in Korean, "Mugunghwa flower has blossomed", referring to the Hibiscus syriacus, the national flower of South Korea.^[67] The use of this familiar character was meant to juxtapose memories of childhood and unsettling fear in the players, according to Chae.^[94] Similarly, the set for the dalgona game, using giant pieces of playground equipment, were to evoke players' memories of their childhood, and was a common place where South Korean children would have played dalgona with friends.^[94] The dalgona used in "The Man with the Umbrella" were made by a street vendor from Daehangno.^[96]

Throughout the series, the trio of circle, triangle, and square shapes appear frequently on the cards given to recruit players, on the guards' masks, and in the show's title card in most language adaptations. These are shapes associated with the playing field for the children's game of Squid (ojingeo). They are also used to represent the hierarchy of the guards within the complex. Following from the comparison with an ant colony, the guards with circles are considered the workers, triangles as the soldiers, and squares as the managers (see also: Korean honorifics).^{[97][better source needed]}

Principal photography for the second season was scheduled to start in July 2023 and was expected to last for "at least 10 months".^[98] On July 10, staff members of the production faced a controversy involving allegations of mistreatment towards citizens during filming at Incheon Airport. The production company issued an official apology on the matter.^[99] Filming was reportedly underway in August 2023.^[100] Filming took place simultaneously with the third season and wrapped in June 2024.^[101]

Jung Jae-il, who previously composed the soundtrack for Parasite, composed and directed Squid Game's score.^[102] To prevent it from becoming boring, he asked the help of composers Park Min-ju, and Kim Sung-soo, a music director for musicals who uses the stage name "23" as a composer.^[103]

Two classical music pieces are also used throughout the show as part of the players' routine: the third movement of Joseph Haydn's "Trumpet Concerto" is used to wake the players, and Johann Strauss II's "The Blue Danube" is used to indicate the start of a new game.^[102] Ludwig van Beethoven's "Fifth Symphony" is also heard in the VIP lounge.^[102] A cover of "Fly Me to the Moon",^[h] arranged by Jung and sung by South Korean artist Joo Won Shin, was used over the "Red Light, Green Light" game of the first episode; according to Joo, Hwang wanted a contrast between the brutal killing of the players and the "romantic and beautiful lyrics and melody" of the song, such that the scene "embodies the increasingly polarized capitalist society that we live in today in a very compressed and cynical way".^[104]

For the song "Way Back Then" that accompanies children playing Squid Game, Jung wanted to use instruments that he practiced in elementary school, such as recorders and castanets.^[103] The rhythm of the song is based on a 3-3-7 clapping rhythm that is commonly used in South Korea to cheer someone on.^[103] The recorder, played by Jung himself, had a slight "beep", which was unintentional.^[105] The song "Round VI" was played by the Budapest Scoring Orchestra.^[106] The soundtrack was released on September 17, 2021.^[107]

Jung returned to score the second season, with the soundtrack album being released on December 27, 2024, through Netflix Music.^[108] Jung confirmed his involvement in 2023, telling the BBC the second season would retain some elements from the score to the first season but have a "more bizarre and unique sound".^[109] The second season also features the aria "Nessun dorma" from Giacomo Puccini's Turandot and "Time to Say Goodbye" by Sarah Brightman and Andrea Bocelli.^{[110][better source needed]}

The first season of Squid Game was released on September 17, 2021, in more than 190 countries.^[111] The second season was released on December 26, 2024.^[36] The third and final season was announced alongside the premiere of the second season,^[112] and was released on June 27, 2025.^[113]

In the Netherlands, Netflix hosted its own Squid Game where people were able to play the game Red Light, Green Light in both Maastricht and Rotterdam. A replica of the doll was exhibited and staff were dressed as guards. Winners were awarded with Squid Game memorabilia. The event attracted hundreds of people.^{[122][123][124]} Similar events featuring replicas of the doll occurred across the world, including Sydney^[125] and the United Kingdom.^[126]

New game modes were added to Call of Duty that comes from the show.

The first season received critical acclaim.^[142] On review aggregator website Rotten Tomatoes, 95% of 77 reviews are positive for the first season. The website's critics consensus reads: "Squid Game's unflinching brutality is not for the faint of heart, but sharp social commentary and a surprisingly tender core will keep viewers glued to the screen – even if it's while watching between their fingers."^[136] On Metacritic, the first season has a weighted average score of 69 out of 100 based on 13 critics, indicating "generally favorable reviews".^[137]

The second season received generally positive reviews from critics. On the review aggregator website Rotten Tomatoes, 83% of 94 critics' reviews are positive. The website's consensus reads: "While Squid Game's return can't help but lose the element of surprise, some absolutely diabolical challenges and a knotty moral outlook keep this sophomore season thrilling."^[138] On Metacritic, the second season has a weighted average score of 62 out of 100 based on 36 critics, indicating "generally favorable reviews".^[139]

The third and final season was met with generally positive reviews from critics. On the review aggregator website Rotten Tomatoes, 79% of 58 critics' reviews are positive. The website's consensus reads: "The games reach a grim crescendo in this climactic third season, repeating familiar beats but with a ruthlessness that drives creator Hwang Dong-hyuk's themes home."^[140] On Metacritic, the third season has a weighted average score of 67 out of 100 based on 26 critics, indicating "generally favorable reviews".^[141] However, some news outlets reported that audience reception to the third season was more mixed, showing roughly half-positive and half-negative user reviews on Rotten Tomatoes.^[143] The New York Times commented that to justify a second or third season as a creative work, "there had to be something that surprised us," and criticized the show for repeating formulas it had only recently established. The review noted that while the protagonist Gi-hun's decisions provided tension, some supporting characters drawn from Western and war film archetypes felt one-dimensional and predictable. It further argued that while Hwang Dong-hyuk still staged action skillfully, his imagination seemed lacking.^{[citation needed]}

The first season of the series became the first Korean drama to top Netflix's top ten weekly most-watched TV show charts globally. It reached number one in 94 countries, including the United States and the United Kingdom.^[144] Netflix estimated that Squid Game had drawn over 111 million member households worldwide after 17 days of availability,^[145][i] and over 142 million member households after 28 days, and becoming the service's most-watched series at its launch.^[146] After Netflix revamped its published metrics of viewership in November 2021 based on total hours watched of the series, Squid Game remained the most-watched show on the service, with over 1.65 billion hours within its first 28 days compared to Bridgerton's 625 million hours.^[147]

Squid Game is considered one of the latest examples of the Korean Wave, the growing trend of popular South Korean media to gain international attention since the early 2010s, similar to popular Korean pop acts like BTS and Korean dramas and films like Parasite. Such works had drawn more attention due to streaming services like Netflix and YouTube making South Korean content, traditionally controlled by the country's national broadcasters, available across the globe. Further, according to Choe Sang-Hun of The New York Times, South Korean creators have a way of taking ideas from foreign works and applying their own cultural spin on it that draws in more audiences.^[148]

The first season's four SAG Award nominations also made history in it becoming the first non-English series and first Korean series to be nominated for Outstanding Performance by an Ensemble in a Drama Series. Individually, Lee Jung-jae became the first male actor from Asia and South Korea to receive an individual SAG Award nomination in television and HoYeon Jung became the second actress of Asian as well as Korean descent to do the same.^[149] With both actors winning, the show made history in becoming the first non-English language television series to win at the SAG Awards. The show also received 14 nominations for the Primetime Emmy Awards, including for Best Drama, making it the first non-English show to be nominated in this category.^[150]

Hwang wrote Squid Game based on his own personal experiences and observations of capitalism and economic class struggles within South Korea.^[43] Hwang also considered that his script was targeted towards global issues regarding capitalism, stating, "I wanted to create something that would resonate not just for Korean people but globally. This was my dream." He added, "I do believe that the overall global economic order is unequal and that around 90% of the people believe that it's unfair. During the pandemic, poorer countries can't get their people vaccinated. They're contracting viruses on the streets and even dying. So I did try to convey a message about modern capitalism. As I said, it's not profound."^[9]

Hwang had also worked with Netflix to create a mockumentary inspired by Squid Game's success, titled The Best Show on the Planet. Hwang said the comedy was based on his own personal experience of being pushed into the spotlight due to the rapid and ongoing success of Squid Game.^[152]
