This is terrible! Hurry! Sonic the Hedgehog - everyone is waiting for your help!
— The Japanese manual for Sonic the Hedgehog
Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ Sonikku za Hejjihoggu?) is a platform video game developed by Sonic Team and published by Sega for the Sega Mega Drive. Featuring the new mascot of Sega, the titular Sonic the Hedgehog, this game served as the launch title for the famous video game franchise known as the Sonic the Hedgehog series.
The game was originally released for the Sega Mega Drive in North America and Europe on 23 June 1991, with a Japanese Mega Drive release following a month later on 26 July. Advertising its fast gameplay based on Sonic's extraordinary speed, the concept of a high-speed platform game was unique for its time and solidified the style of gameplay the series would be best known for. Due to the Mega Drive's Motorola 68000 processor, the power of the console would allow for faster gameplay, dubbed by some as "blast processing," and impressive 16-bit graphics, making it much more powerful than Sega's preceding Master System.
The game was well praised by critics and was a massive commercial success, which gave the Mega Drive, and by extent Sega, a huge boost in popularity, enough so that Sega could directly compete with Nintendo, who soon followed up with the release of their Super Nintendo Entertainment System. This would result in what would be the first counterattack in a long company rivalry that lasted throughout the 90s. In recent years, the game has been ported numerous times on many other consoles, with some ports adding newer features to the original game.
On the lush, tropical paradise of South Island, Sonic the Hedgehog's animal friends begin disappearing one by one. When he discovers that the evil scientist, Dr. Ivo Robotnik, has been kidnapping them and converting them into robotic Badniks as part of a plot to collect all six of the fabled Chaos Emeralds, Sonic decides it's up to him to save them, and embarks on a quest to free his friends, locate the Chaos Emeralds first and thwart the evil schemes of Robotnik.
As Sonic races through the Zones of the island, he engages in numerous confrontations with the nefarious Robotnik and his deadly machines, and one by one frees the animals from their robotic shells and capsules placed at the end of almost every zone. In their final confrontation, the Doctor prepares his last dastardly contraption to end his adversary but proves no match for Sonic's awesome might, and his machine is totaled. Fleeing with his tail between his legs, Robotnik abandons his laboratory as it explodes, crumbling to scrap, with Sonic narrowly escaping. Following his escape, Sonic finally returns to the vast Green Hills where his journey began.
In the game's normal ending, Sonic gives the player an annoyed look before posing for the screen, and Robotnik will be shown after the credits juggling all the Chaos Emeralds the player missed, showing that he had gotten what he had came for in the first place, with a "Try Again" message taunting them.
However, if the player succeeds in collecting the six Emeralds by the end of the game, the player is rewarded with the good ending, where the six Chaos Emeralds react to one another and release a burst of light before disappearing, rejuvenating the wildlife and nature of South Island, leaving Sonic astonished before he jumps up towards the screen and poses. In the post-credits scene, Dr. Robotnik is shown humorously stomping on the "End" text in a tantrum-fueled attempt to crush it, to no avail.
Sonic the Hedgehog plays identically to other platform games released around the same time, yet its primary focus is on fast gameplay and quick reflexes. The titular character can not only run and jump, but he can pick up incredible speed if uninterrupted and can roll into a ball and spin into enemies and up ramps with enough momentum, allowing him to launch himself high up into the air or through a stream of Badniks.
There are seven zones in total, with each zone, barring the Final Zone, divided into three Acts each. Sonic must reach the end of each Act within ten minutes while collecting items and avoiding hazards along the way. The game also features underwater sections that can be traveled through, though Sonic can only spend thirty seconds underwater before drowning, unless the player grabs an Air Bubble, thereby resetting the countdown. In order to conclude Act 1 and 2 of a Zone, the player has to pass a Goal Plate at the end of said Acts. To complete the third Act of a Zone on the other hand, the player typically has to open a Capsule at the end of the Act, after the boss fight.
At the end of the third Act of each zone (except the Scrap Brain Zone), Sonic faces off against Dr. Robotnik, who is piloting his Egg Mobile. For each battle, Robotnik's machine has a different tactic. Sonic must hit each boss eight times to destroy it.
Essential to the gameplay are gold Rings scattered throughout each level, a feature which would become one of the defining characteristics of the series. These items are regularly placed around the level map and serve multiple functions. First, the player collects rings to protect Sonic. As long as they have at least one ring, the player will not lose a life when injured. Instead, when hit, up to twenty of the rings the player has collected will fly outward and scatter around the immediate area for some seconds, some of which can then be retrieved before they disappear. If the player runs into an enemy without a single ring, they will lose a life. If the player collects a hundred rings they will gain an extra life, and will gain an additional life for every hundred rings after that, provided the rings are not lost.
If the player has at least fifty rings at the end of an act, a giant golden ring will float above the Goal Plate, which can be jumped through to enter one of six Special Stages (this excludes the final act of a stage, when Sonic will enter a boss fight). Once the player has cleared all six Special Stages, the Giant Rings will no longer appear. If Sonic does not jump in before the Goal Plate stops spinning, he will uncontrollably run off of the screen and the Special Stage is lost. At the end of each act, the total number of rings the player has is multiplied by a hundred and added to the player's score. During the score-tallying, the player can also jump through the air to find invisible Bonus Points that are added to the score. They can be worth 100, 1000, or a sweet 10,000 points.
Also scattered throughout each level are video monitors which when broken by the character will reward the player with one of a variety of bonuses. These include a Shield which will protect Sonic from a single hit, a 10-ring bonus, an extra life, temporary invincibility (accompanied by a temporary change in music), and "Power Sneakers", which give the player a temporary speed boost (and increase the tempo of the music for the duration). The item monitors have become another long-lasting feature in the series, though they have been changed to bubble-like containers that can float in later games.
Despite the various types of protection available, neither the shield, rings, nor invincibility will prevent the player losing a life if Sonic is crushed (by a trap or between a wall and a moving platform), drowned, runs out of time (each act has a ten-minute time limit), or falls into a bottomless pit.
Progression through the game is made easier for the player by Lampposts that act as checkpoints. When Sonic passes a lamp post, the spherical top spins around and its color changes from blue to red, and the next time a life is lost, gameplay will restart at that point rather than at the beginning of the act. In the Japanese version, if a checkpoint is activated and a life is lost as a result of running out of time, the time at the checkpoint will reset to 0:00.
Hazards the player experiences include a wide variety of "Badniks" - these appear as Animals trapped inside mechanical bodies which are released the moment the player hits them. Each badnik takes one hit to destroy, but they vary greatly from Zone to Zone; some will walk in a set path, others will try blasting the player, and some cannot be avoided at all. The player must also avoid rows of sharp spikes, cliffs, and elaborate death traps. There is also the threat of drowning (in Labyrinth Zone and the third Act of Scrap Brain Zone which contains water), as the player can only survive approximately thirty seconds underwater (locating air bubbles can extend this).
|Walk||Push left or right on the D-pad to initiate Sonic's movement in either direction. As the player holds the button down, Sonic gains speed.|
|Run||Begin walking and hold down the button to make Sonic gain speed. After a few seconds, he'll break into a run.|
|Screech halt||While running, quickly press and hold the opposite direction on the D-pad to make Sonic screech to a halt. He'll skid for a short distance, based on how fast he was moving.|
|Look up||While standing still, press up on the D-pad to make Sonic gaze to the sky. As the player holds up, the camera pans upward, giving player a view of Sonic's overhead surroundings.|
|Crouch||While standing still, press down on the D-pad to make Sonic duck down. As the player holds down, the camera pans downward, giving player a view of the stage beneath where Sonic stands.|
|Super Sonic Spin Attack||Often called the Spin Attack or just the roll in later games, pressing down on the D-pad while moving will make Sonic curl into a rolling attack. He'll remain in this position until the player jumps or slows down. The speed of Sonic's movement while in spin mode is based on how fast the player was moving when they initiated the Spin Attack.|
|Super Sonic Spin Jump||Renamed the Spin Jump in later games, pressing an action button at any time will make Sonic leap into the air with a rolling attack. The height of the jump is proportional to how long the player held the button down.|
|Push||Certain blocks can be pushed by running up against them. Continue holding the D-pad against the offending cube to have Sonic push it along the ground. This sprite will also be shown if the player attempts this with an object that can't be pushed that doesn't harm them.|

Sonic the Hedgehog has seven zones (plus the Special Stages). The first six zones contain three full-length Acts, and the final one only consists of the final boss machine.
- Green Hill Zone
- Marble Zone
- Spring Yard Zone
- Labyrinth Zone
- Star Light Zone
- Scrap Brain Zone
- Final Zone
If Sonic finishes the first or second Act of any of the first five zones with at least fifty Rings, a large, spinning ring will appear. If he jumps into it, he will warp into a "Special Stage" (called the "Secret Zone" in the manual), which conceals one of the six Chaos Emeralds. In these stages, Sonic, in ball form, falls through a series of rotating mazes.
If he can avoid the "GOAL" signs along parts of the stage's walls (presumably labeled "GOAL" to entice the player into a failed attempt at getting a Chaos Emerald), he will eventually find the Chaos Emerald encased in colored diamonds; touching the diamonds repeatedly will cause them to change color from blue, to green, to yellow, to pink and ultimately disappear, allowing access to the Emerald. The stage will end when Sonic either touches the Emerald or hits a "GOAL" sign. If fifty Rings are collected before Sonic makes contact with a "GOAL" sign or gets the Chaos Emerald, then a 'Continue' will be awarded to the player, indicated by a brief, distinct change in melody. Super Sonic does not appear in Sonic the Hedgehog because the seventh Chaos Emerald was not yet introduced.
There are a total of ten opportunities to get Chaos Emeralds, meaning the player can fail a Special Stage up to four times if all six Emeralds are to be collected before the end of the game. Scrap Brain Zone will not have a large ring at the end of it, even when finishing with fifty rings, despite the acts ending before it. If the player fails a stage, that stage is skipped and is returned to after attempting the sixth and final Special Stage.
It is stated in the North American and European manuals that a 1-Up item can be found in Special Stages, but they are not seen anywhere unless placed in the game's secret Debug Mode. It is possible, however, to earn extra lives by collecting a hundred rings in a single stage, indicated by the same sound used in the main zones.

Master System and Game Gear
As the Master System still had high sales in South America (and in limited amounts in the US through retail stores), an 8-bit version of Sonic the Hedgehog was produced for the Master System market. This version had similar zone themes and regular enemies, but entirely different level layouts and bosses. The Master System version was released for the Wii Virtual Console on 4 August 2008. This version was also made available worldwide for the Game Gear, with adjustments due to the smaller screen.
- Level Select - At the title screen, press UP, DOWN, LEFT, RIGHT, then hold A and press start.
- Debug Mode - At the title screen, press UP, C, DOWN, C, LEFT, C, RIGHT, C (or C, C, UP, DOWN, LEFT, RIGHT), start, then hold A until the game starts.
There are seven particular glitches in the game that could either help or make things much worse for Sonic.
- Too fast Sonic in the Green Hill Zone; Result: If going too fast down two tubes in Green Hill, the camera won't respond and Sonic will die at the ledge to the giant ring pattern.
- Rolling after Labyrinth Zone Act 2's end; Result: An illegal instruction error will proceed if this glitch is triggered, making the player reset the game.
- Too many hits on the Final Zone's boss; Result: If timed correctly, the player can hit Robotnik two times on the final hit, showing that he would need to be hit 255 more times, which is normally impossible under the time limit.
- Sonic jumps too far away in the Final Zone; Result: Sonic would jump off into the bottomless pit, therefore losing a life.
- Move through walls in Scrap Brain Zone; Result: On one of the moving platforms, Sonic can duck and go through the wall, showing that he has been placed in another location.
- "Spike Bug"; Result: Though this is technically intentional, Sonic isn't invulnerable to spike damage immediately after taking a hit. This causes instant death (or an endless loop, if on debug mode). This was fixed in later games and in certain ports.
- Robotnik camps forever; Result: While using Debug Mode, go underneath the Final Zone. The player should be thrown as far left as possible, then go to the very top of the Zone. If timed correctly, Robotnik should not attack, thus forcing the player to restart the game to fix it.

As a celebration of the Mega Drive's 25th anniversary in Japan, Sega released another port for Nintendo 3DS titled 3D Sonic the Hedgehog, which is part of series of Mega Drive games re-released to take advantage of 3D. The port also features Spin Dash as an optional move, Stage Select feature, input settings, sound settings, the option to toggle the original revisions, and separate display settings with stereoscopic sense to create a 3D experience. It is was released in Japan on 15 May 2013, and was later released in North America and PAL Regions on December 5, 2013.
|Nintendo 3DS||Sonic the Hedgehog is one of the Sega games included in a compilation of classic games titled Sega 3D Classics Collection. While it is titled 3D Sonic the Hedgehog, this compilation title takes advantage of stereoscopic 3D to create a 3D experience.|
Developed by Christian Whitehead and Headcannon, this remastered edition of the original Sonic the Hedgehog includes several features including an optional Spin Dash, Miles "Tails" Prower and Knuckles the Echidna being playable characters and an expanded Level Select and Debug Mode.
Re-released as part of the SEGA AGES line for the Nintendo Switch, Sonic the Hedgehog includes some features such as the Spin Dash and Drop Dash from Sonic Mania and two modes: Ring Keep Mode and Time Attack. It was released on September 20, 2018.
The original Sonic the Hedgehog was very well received by critics, scoring 86% from GameRankings. The game was an instant success that allowed Sega to wrap their video game business around and have a platformer to compete with Nintendo's Super Mario franchise. The gameplay, audio and graphics were praised by reviewers.
IGN reviewer Lucas M. Thomas rated Sonic the Hedgehog an 8/10, praising the simple but fast gameplay, the soundtrack and commended that "few people realize how difficult it was to create Sonic's graphics engine, which allowed for the incredible rate of speed the game's known for. The technical achievement impressed back in '91, and still does so today." Gamespot reviewer Greg Kasavin gave the game a 7.3/10, praising the great soundtrack and memorable sound effects, the fast-paced, responsive platformer action and cute, colorful graphics [that] have a good deal of charm and personality although he felt that the later levels can get frustrating tough, requiring meticulous memorization.
- The European box art is similar to the Japanese box art.
- The Japanese release added additional storyline details, as the existing plot was virtually a basic outline. The purpose of the Chaos Emeralds is greatly expanded upon, which is elaborated in later games. It is explained that Dr. Robotnik was specifically searching for them on the island due to their incredible energy according to legend. The manual also states that there has already been some unknown animosity between Sonic and Robotnik in the past (which, on the other hand, is not backed up in later games). It also lists the setting as South Island, which is established in later games as well - in the English manual, the setting was originally unnamed.
- There are two versions of the game. This revision is common in Japan, but contrary to popular belief it was released worldwide in smaller quantities. This update makes some very minor changes to the game's programming, as well as adds some visual effects such as scrolling clouds in Green Hill Zone or water ripples in Labyrinth Zone. It also corrects the Zone order on the level select. This version of the game is used in most subsequent releases. In addition, the scrolling clouds return in most appearances of Green Hill Zone.
- Rui Sousa holds the high score for Sonic the Hedgehog: 1,559,180. He achieved this on 21 March 2015.
- There was a sound test that was originally supposed to be in this game but was scrapped. But one character in this sound test appeared in future games (Vector) while the others appear in the Archie Comics as part of Mina Mongoose's band.
- A variant of this game's Special Stage also appeared in Sonic the Hedgehog 4: Episode I.
- There were only six Chaos Emeralds in this game. A seventh emerald was introduced in Sonic the Hedgehog 2.
- The game's 2013 re-release adds a seventh emerald, making Super Forms possible.
- In each version of the game's box art, Sonic is making the same pose.
- Out of the main series classic Sonic games (including both episodes of Sonic the Hedgehog 4 and Sonic Mania), this is the only game whose final boss doesn't take place in space.
- Masato Nakamura did say in an interview that when he was composing the music for this game, he thought the game as a film to compose the music.
- This is one of the games to be represented in Sonic Generations. Green Hill reappears as the first stage of the Classic Era in both the home and portable versions.
- This game's theme music would later be remixed and used as the theme for Sonic the Hedgehog 2 and Sonic Generations.
- Also, the opening and ending of this game's ending theme were remixed and used for the opening and ending theme for Sonic Generations.
- Strangely, the PlayStation Network port of the game was rated E10+ by the ESRB. However, that has been changed to an E rating in 2013.
- In the G4 special Top 100 Video Games of All Time, the game was ranked at #50.
- The game was meant to move at an even faster pace, but that idea was cut from the final version, as Yuji Naka got motion-sickness from it.
- The game was listed in the book 1001 Video Games You Must Play Before You Die. In addition, Sonic the Hedgehog 2 and Sonic Adventure were also listed.
- This is one of the few Sonic games that when it crashes, it has something debug-related happen. In this game's case, sometimes when a crash happens, an error code comes on the screen.
- The title icon for this game, and several corresponding games, resembles the logo for the restaurant chain Steak 'n Shake.
