Ultraviolent Korean TV show Squid Game has become a Netflix smash hit with its story of hundreds of indebted men and women competing on a deadly game show in twisted children's games for a £27 million cash prize. The nine-episode series has soared to number one on the streaming giant's rankings with blood-soaked scenes of bullets fired into contestants' heads, bodies piled high and graphic dissection as their organs are harvested afterwards. Each episode revolves around a traditional Korean children's game, with some like Grandma's Footsteps and British Bulldogs, and the winners progress to the next round in a gruesome version of Takeshi's Castle. Adding to the depravity, the contestants are poor people who are enticed to compete to win a grand prize of 45 billion won ($38m, £27m, AU$52m). A contestant is covered in blood after another player's head is blown off in a hellish version of a Grandma's Footsteps type game played in one of the early episodes Sae-byeok is played by top fashion model HoYeon Jung, 27, (pictured) in her first-ever screen role Terrifying masked assassins roam around in the game show and kill the contestants who fail The unlikely heroes are Seong Gi-hun (Lee Jung-jae), a failed father and gambling addict, and his flawed childhood friend Cho Sang-woo (pictured) (Park Hae-soo), a disgraced banker wanted by the police.

The candy-coloured sets of this fictive game show appear like a children's playground, but they are anything but, as masked men strapped with machine guns stand-by to shoot the losing contestants. But not even the dead are spared, as a doctor is sent to dissect the losing players' corpses to harvest their organs after each round. As the story progresses, the contestants are increasingly pitted against each other, culminating in the final round, the eponymous Squid Game, in which the chief protagonist Gi-hun must kill his childhood friend Sang-woo. It is the game show-style narrative which reviewers say makes it so addictive, with the audience intrigued as to what will be the next stage in the grisly game and who will progress to the next rank. This fast-paced narrative structure runs alongside well developed protagonists with captivating back stories who the viewer hopes will survive the onslaught. Every episode is now available on Netflix, with a dubbed English version or with the original Korean audio and subtitles.

With the massive success of the series, there are already questions about whether there will be sequel. But writer and director Hwang Dong-hyuk, who has had massive success on the big screen in recent years, said he might have to return to movies before he gets there. 'I don't have well-developed plans for Squid Game 2,' he told Variety. 'It is quite tiring just thinking about it. But if I were to do it, I would certainly not do it alone. I'd consider using a writers' room and would want multiple experienced directors.' All rights reserved for this news site (dailymail) and under his responsibility
