Myst is a graphic adventure video game designed and directed by the brothers Robyn and Rand Miller. It was developed by Cyan (now Cyan Worlds), a Spokane, Washingtonbased studio, and published and distributed by Brderbund. The Millers began working on Myst in 1991 and released it for the Mac OS computer on September 24, 1993; it was developer Cyan's largest project to date. Remakes and ports of the game have been released for Sega Saturn, Microsoft Windows, Atari Jaguar CD, 3DO, CD-i, PlayStation, AmigaOS, PlayStation Portable, Nintendo DS, and iOS by publishers Midway Games, Sunsoft, and Mean Hamster Software. Myst puts the player in the role of the Stranger, who uses a special book to travel to the island of Myst. There, the player uses other special books written by an artisan and explorer named Atrus to travel to several worlds known as 'Ages'. Clues found in each of these Ages help to reveal the back-story of the game's characters.
