Sonic the Hedgehog is a multidirectional scrolling platform game developed by Sonic Team and published by Sega in 1991 for the Genesis/Mega Drive.
The 8-bit Sonic the Hedgehog is a side-scrolling platform game similar in gameplay and style to the original 16-bit Sega Genesis game of the same name, save for several new and altered game mechanics. As in the original, the anthropomorphic hedgehog Sonic ventures to rescue the animal population of South Island from the diabolical Doctor Robotnik, who plots to turn them into robots. The player jumps between platforms, avoids enemy and inanimate obstacles, and breaks televisions to collect shields, speed shoes, and invincibility, and mark checkpoints. Like the original, Sonic collects rings, which protect him from being hit by an enemy or obstacle. The player starts the game with three lives and will lose one if they are hit without carrying any rings, drown, fall into a bottomless pit, or reach the act's 10-minute time limit.The game ends when the player runs out of lives, although they can return to the beginning of the current act if they have any continues. Gameplay is slightly slower and more focused on exploration than the original.
Sonic travels through six levels called zones, each consisting of two main acts and a boss battle with Robotnik. The zones are based on various themes, such as grassy plains, ancient ruins, and jungles. While some of the level themes, such as Green Hill Zone, are borrowed from the 16-bit version, others are original, and all the level designs are different and contain no vertical loops. Some of the game's levels require quick precision and others require the player to go underwater. Certain acts have Chaos Emeralds hidden within them, and the player must collect all six to obtain the best possible ending. At the end of each main act, the player hits a signpost, which will spin and land on an image; it can award bonuses depending on the image it settles on. If the player has over 50 rings, they can access a pinball-esque bonus stage where more rings and continues can be collected.
