Sammy Corporation is a Japanese developer and retailer of pachinko and pachislot machines, headquartered in Shinagawa, Tokyo. Its South Korean office, Sammy Amusement Service, is headquartered in Seoul, South Korea. Sammy is a subsidiary of the entertainment conglomerate Sega Sammy Holdings. Sammy was founded as Sammy Industry on November 1, 1975 as a spin-off of the arcade division of Satomi Corporation. The company primarily dealt with slot machines and arcade cabinets in Japan. Sammy expanded into video game development in the 1990s with games such as Viewpoint, Survival Arts, and The Rumble Fish. Sammy largely abandoned the video game industry by the late 1990s to focus on its pachinko and arcade management operations. In 2004, Sammy merged with video game developer and publisher Sega to form Sega Sammy Holdings.
