 Spidersoft mostly developed ports or adaptations of other games, predominantly to Game Boy, Game Gear and MS-DOS, including pinball-based video games developed by Digital Illusions and published by 21st Century Entertainment.Following the success of "Pinball Fantasies" in 1992, and its subsequent ports to other platforms, including Spidersoft's 1995-released ports to Atari Jaguar, Game Boy, PlayStation and Super Nintendo Entertainment System, 21st Century Entertainment acquired a controlling stake in Spidersoft.Through the purchase, 21st Century Entertainment aimed at ensuring a steady supply of further pinball games and avoiding the need to rely on third-party contractors, such as "Pinball Fantasies" developer Digital Illusions, which appeared to want to cease operations in the pinball games niche market.
