God of Gamblers (; lit. God of Gambling) is a 1989 Hong Kong action comedy-drama film written and directed by Wong Jing featuring an all-star cast led by Chow Yun-fat, Andy Lau, Joey Wong and Sharla Cheung. Plot Ko Chun is a world-famous gambler, so renowned and talented at winning various games of chance that he is referred to as the "God of Gamblers". He keeps his identity secret from the public (and avoids photographs so his face is not recognised), but is known for three characteristics: his slicked-back hairstyle, his love of Feodora brand chocolate, and his jade pinky ring. Ko Chun arrives in Tokyo, accompanied by his girlfriend Janet and his assistant and cousin Ko Yee, for a match with Tanaka, the country's top ranked gambler. After convincingly defeating Tanaka in games of Mahjong and dice, Tanaka concedes defeat and asserts that Ko Chun "really [is] God". Tanaka asks Chun to help him take revenge on Chan Kam-sing aka the "Demon of Gamblers", a famous Singaporean gambler who cheated Tanaka's father before driving him to suicide, by besting Chan in a high-stakes poker match. Ko Chun agrees, merely asking for a box of chocolate as payment. In gratitude, Tanaka sends his bodyguard, former Army of the Republic of Vietnam Special Forces Operative, Dragon, to accompany Ko Chun for protection. Meanwhile, Little Knife, an avid but mediocre gambler who idolises the God of Gamblers, sets a trap for an Indian neighbour as a practical joke. After a fight on a train between Ko Chun, Dragon, and henchmen sent by one of Ko Chun's rivals, Ko happens to accidentally stumble into Knife's trap. Ko falls down a hill, hitting his head, and subsequently suffers from amnesia and regresses to a childlike state. Knife, not knowing who the unnamed stranger is, takes him in and names him "Chocolate" due to the man's seemingly obsessive love for the candy. Initially Knife is impatient with Chocolate's childish innocence and often yells at him, but soon recognises that "Chocolate" has innate gambling talent and begins to exploit his abilities in local poker games and gambling dens. As time passes, Knife comes to care for Chocolate and seeks to find a way to restore his memory. Back at Ko Chun's mansion, it is revealed that Janet has been searching for Chun for ten days to no avail. Ko Yee, who is jealous of Chun's success
