SegaSonic the Hedgehog is a 1993 arcade game in the Sonic the Hedgehog series by Sega. Controlling Sonic the Hedgehog and his friends Mighty the Armadillo and Ray the Flying Squirrel, the player must escape an island after they are kidnapped by the villain, Doctor Eggman. The game uses an isometric perspective. Players use a trackball to move the characters while dodging obstacles and collecting rings. The game was developed by Sega's arcade division, Sega AM3. It is one of four Sonic games with the SegaSonic name and was inspired by the 1984 game Marble Madness. SegaSonic the Hedgehog was released in Japanese arcades in late 1993. It has never been rereleased; a port for Sega's 32X never materialized, and the game was cut from the compilation Sonic Gems Collection (2005) due to problems with replicating the trackball control system on a standard controller. At the time of release, SegaSonic the Hedgehog received positive reviews from Electronic Gaming Monthly and Computer and Video Games for its graphics and gameplay. Retrospective reviews have been more divided. The game marked the debuts of Sonic characters Mighty and Ray; both have reappeared sparingly in the franchise.
