Port of the Game Gear title to the Sega Master System, honestly not the best way to play the game, the extra screen is actually garbage data, making it a bit confusing to play, unless you wanna play this on real hardware or using a Master System only emulator I recommend playing the GG version instead as this version does not give you any extra viewpoint.

With advanced ability of Sonic to smash through walls and grab back scattered rings hit by enemy, this platform video game is made even more exciting. Join the protagonist in the Sonic the Hedgehog 2 game as he rides a mine cart, a hang glider or skims through water surface in his rescue attempt. With seven zones and three acts each, this Sega Game Gear video game is a rollercoaster ride where you get rewarded at the end of each act.

Blue Sphere, known as Special Stage Mode in Sonic & Knuckles Collection, is an easter egg video game built into the Sonic & Knuckles cartridge for the Sega Mega Drive, accessible by attaching any Mega Drive game cartridge (other than Sonic the Hedgehog 2 or Sonic the Hedgehog 3) into the Sonic & Knuckles lock-on port. Blue Sphere is a collection of Special Stages in the same style and engine of those featured in Sonic the Hedgehog 3 and Sonic & Knuckles. If the cartridge that is locked on to Sonic & Knuckles is the original Sonic the Hedgehog (Sonic Classics, the Nick Arcade and Simon Wai prototype versions of Sonic the Hedgehog 2 will also work), then the full game of Blue Sphere is accessed with all stages. Most other cartridges will allow the player to access only a single stage of the game, based on the cartridge's ROM header and the stage's code in the full Blue Sphere game. Some cartridges with particularly large ROM file sizes (including Phantasy Star IV: The End of the Millennium and Super Street Fighter II: The New Challengers) will not load Blue Sphere, but will instead boot Sonic & Knuckles as normal. Locking on Sonic & Knuckles to another copy of Sonic & Knuckles will also load the game normally.

SegaSonic the Hedgehog is an isometric platforming game with three characters who shares identical controls and abilities. The characters are controlled with one action button which lets the player perform a spin jump, and a trackball which is used to move the characters around. Each trackball and corresponding action button are color-coded, meaning the blue ones are for Sonic, red ones are for Mighty and yellow ones are for Ray. The premise of the game is to reach the end of an isometric course without dying. This objective is similar to other video games in the Sonic the Hedgehog series. Yet, it is also different in the sense that instead of a typical platforming game, the game is centered entirely around running as fast as possible on a linear course from a never-ending barrage of threats, including giant boulders, lava flows, rogue gears, falling stalactites, and other traps. When the player is hit by a dangerous obstacle or hazard, they lose health from the Health Gauge, which can be refilled by collecting Rings that found around the arena. Upon completing each level, the game tallies up how many Rings were grabbed. Extra points are also received if over half of the level's Rings were found. The game only has a few enemies and one boss that appears midway through the game. At the end of the final level, the player is given twenty seconds to escape from the self-destructing tower. Failure results in an instant Game Over.
