Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ Sonikku za Hejjihoggu?) for the Sega Mega Drive is the first title in the Sonic the Hedgehog series, and the third appearance of Sonic the Hedgehog. The game's original programmer was former Sonic Team leader and series creator Yuji Naka, and the planner was Hirokazu Yasuhara. The gameplay was faster than any other game before it and amazed many people at launch. This was due to the Mega Drive's Motorola 68000 processor, whose basic speed and ability to handle 16-bit numbers gave it incredible speed compared to its predecessor, the Master System. Nevertheless, a separate 8-bit version, which focused more on exploration than speed, was later released for said system.
South Island is a treasure trove of gems and ancient ruins. They say that it's the island where the mystical Chaos Emeralds lie. The Chaos Emeralds are a super-material that give energy to all living beings. However, when applied to scientific purposes, they can be used for nuclear and laser based weaponry. Nevertheless, nobody knows exactly how to get a hold of these emeralds. At the same time, it is said that the reason why South Island is always moving is because the Emeralds are somewhere inside the island's hazy depths.
Doctor Ivo Robotnik (AKA "Eggman"), tired of Sonic the Hedgehog getting in his way all the time, has come to the island with his forces to launch his first major scheme to conquer the world, and set up a base of operations. Sonic hurried to the island once he heard the news, but found that something was amiss. Dr. Robotnik has kidnapped all of the animals and is using them to fuel his Badnik robots. Essentially, the entire island has become Sonic's enemy. Sonic immediately ran off to help everyone and stop Robotnik's craziest and most ambitious plan yet.
Sonic races through the zones and marks them as his territory, stopping Robotnik and freeing the animals from their egg-like Capsule prisons. (Animals are also freed whenever a Badnik is destroyed.) Chaos Emeralds are obtained through Special Stages, and are optional during the game's progression. However, Sonic will not be happy at the end of the game if he did not get the Emeralds before Robotnik. If Sonic does get the island's six Chaos Emeralds, they will teleport away and bestow new plant life in Green Hill Zone, which astonishes Sonic. If the player fails, Robotnik will juggle the missing emeralds after the credits, with a "Try Again" message displayed on the screen. If the player succeeds, he will childishly jump on the "End" sign.
Sonic the Hedgehog plays very similarly to other platformers, in which the titular character must get to the end of the stage in the allotted time, while collecting the items along the way. Essential to the gameplay are the golden rings the player collects along his/her way in 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 20 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 100 rings they will gain a life, and will gain an additional life for every 100 rings after that, provided the rings are not lost.
If the player has at least 50 rings at the end of an act, a giant golden ring will float above the finishing sign which can be jumped through to enter one of the Special Stages (this excludes the final act of a stage, when Sonic will enter a boss fight). At the end of each act, the total number of rings the player has is multiplied by 100 and added to the player's score. During the score-tallying, the player can also jump through the air to find hidden emblems which can range from 100 to 10,000 points. This was the only console Sonic where the player could not get more lives by collecting over 200 rings (this is the only 16-bit title where it is impossible to obtain 300 rings in a single stage).
Also scattered throughout each level are monitors (or TVs as some call them) which, when broken by the character, 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 with a temporary change in music), and "Super 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 lamp posts 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 30 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 you hold 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 you hold up, the camera pans upward, giving you a view of Sonic's overhead surroundings.|
|Crouch||While standing still, press down on the D-pad to make Sonic duck down. As you hold down, the camera pans downward, giving you a view of the stage beneath where Sonic stands.|
|Sonic Spin||While moving, press down on the D-pad to make Sonic curl into a rolling attack. He'll remain in this position until you jump or slow down. The speed of Sonic's movement while in spin mode is based on how fast you're moving when you launch it, and also on the terrain Sonic rolls along.|
|Press any button at any time to make Sonic leap into the air with a spin attack. The height of the jump is proportional to how long you hold 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.|
Sonic the Hedgehog has seven zones (plus the Special stages). The US manual states that there are in fact six zones, possibly because the Final Zone was taken to be the boss of the Scrap Brain Zone and not a zone in itself.
- 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 50 rings, a large, spinning ring will appear. If he jumps into it, he will enter a "Special Stage" that hides a Chaos Emerald. 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 50 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 50 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.
An oddity with the Special Stages is that it is stated in the US manual that 1 Up items can be found in Special Stages, but they are not seen anywhere. It is possible, however, to earn extra lives by collecting 100 rings in a single stage, indicated by the same sound used in the main zones.
Items and Power-upsEdit
|As long as Sonic has some of these, he won't lose a life if he takes damage. Sustain a hit and all your collected Rings will scatter, giving you a brief opportunity to grab a few back before they disappear. (Rings will not protect Sonic from getting crushed by a trap, falling below the level, drowning, or running out of time. All of these effects result in instant death.) A 1up is awarded for every 100 Rings collected and each ring is worth 100 points at the end-of-act score tally. In many later games, Sonic can collect 50 of these to transform into Super Sonic (if the player has all seven Chaos Emeralds).|
|Item Box||In each stage, you'll find a number of these power-up bearing monitors. Pop them open with a spin to procure one of five power-ups:
|Star Post||These hold your place in a stage: should you lose a life, you'll start back at the last star post you crossed.|
|Bumper||Round bumpers found only in Spring Yard Zone and the Special Stages. Bounce off one for 10 points, up to 10 times for a total of 100 points. (They stop dispensing points after the tenth hit.)|
|Spring||Leap onto the broad side to catapult Sonic into the air. The yellow ones send him flying a short distance and the more powerful red ones send him farther.|
|Spikes||Don't touch the pointy side! They're usually found in sets of three, but that's not a steadfast rule. Sometimes they're just lying out in the open, and sometimes they pop in and out of the ground (or the ceiling or walls).|
|Switch||Jump on the button to cause a change in the nearby scenery, usually necessary to proceed.|
|Air Bubbles||Large, oxygen-filled bubbles periodically rise from these clusters: tag one to fill Sonic's lungs with air and prolong the time you can spend underwater. Sonic can only spend 30 seconds underwater without drowning, and grabbing a bubble resets the timer. (Labyrinth Zone and Scrap Brain Zone Act 3 only)|
|Bonus Points||As you approach the bonus plate at the end of an act, leap into the air to find invisible bonus points that are added to your score. They can be worth 100, 1000, or a sweet 10,000.|
|Bonus plate||These signs can be found at the end of each first and second act. Cross them to end the stage.|
|Special Stage Ring||These giant rings appear above bonus plates when you cross with at least 50 rings on hand. Jump in to warp to the Special Stage. (Once you've collected all 6 Chaos Emeralds, the Special Stage rings no longer appear.) If Sonic does not jump in before the bonus plate stops spinning, he will uncontrollably run off of the screen and the Special Stage is lost.|
|Capsule||These are found at the end of each third act, after defeating the boss. Push the button on top to destroy the machine and free the helpless animals within.|
|English name||Japanese name||Sprite||Description|
|Beetle bots with one wheel and two claws, a blue head, a engine, and a red back that roll innocently along the ground. They appear in Green Hill Zone. They are designed after ladybugs.|
|Blue bee bots that actually look like wasps with two yellow antennae with an engine that flies across from the right side of the screen, pausing once to fire a large flashing projectile from their stingers diagonally downward at Sonic. They are seen in Green Hill Zone.|
|Red piranha bots that leap upward from beneath bridges, trying to chomp Sonic. It's best to walk on bridges while in a ball form. They appear in Green Hill Zone.|
|Red crab bots with 6 grey legs that crawl along the ground and fire projectiles from their pincers and shoot 3 inches in the air and then the projectiles drop to the ground.|
|These chameleon bots hang out on the side of cliffs and remain invisible until approached. They come in two colors: blue ones transform into missiles and jet along the ground. Green ones appear just long enough to fire an energy blast at Sonic.|
|Purple Caterpillar bots with yellow spikes on their body and two yellow antennae that crawl slowly along the ground. The safest method of disposal is to roll into their spherical heads: venture a poke anywhere else and you'll sustain damage and send their segments flying. Caterkillers appear in Marble Zone and Scrap Brain Zone.|
|Blue bat bots with one engine, two black or grey claws, and black wings that latch onto ceilings until approached, then drop down and fly through the air a short distance before returning to their roost.|
|Blue armadillo bots with a red face that roll down long slopes after Sonic. They tumble faster than Sonic runs, so leap to avoid being steamrolled. At the bottom of the hill, Roller pauses and briefly opens up: this is your only chance to attack.|
|Purple hermit crab bots with two purple and yellow claws and two yellow wheels that crawl along the ground. Their shells are cloaked with spikes, making them invulnerable from above.|
|Mole bots with two tractor-like wheels, a blue head, and red shoulders, helmets, and arms that spring from underground and roll along the surface. Look for their drill bit noses poking out of the earth to avoid an ambush.|
|Purple piranha bots with a yellow jaw and yellow eyes that swim around underwater. ("Puku-puku" is Japanese onomatopoeia for a bubbling noise.)|
|Irritable blue sphere bots that hover around very slowly. They're orbited by four red spiked balls which they fling off in rapid succession upon being approached. It's a dangerous assault, but once it's done, Unidus is completely open to attack. ("Uni" is Japanese for sea urchin.)|
|These guys, palette aside, look exactly like Unidus. They're a bit more cool-headed, though, with a green sphere in the middle and four yellow spikes surrounding it and won't fire off their barrier of orbs. While this means you don't have that tricky attack to avoid, they're virtually impossible to hit.|
|Mindless bots with gray top and red bottom with two gray legs. Even though they never move, they explode in 5-6 seconds after making contact with it into a shower of projectiles when approached. They can't be damaged, only avoided.|
|Pink Pig bots with a gray ears, gray stomach, gray legs, and a turquoise nose that hop in place atop steep banks and roll balls down the slope. They only appear in Scrap Brain Zone.|
|Blue rabbit robots that just bounce around. These badniks weren't used in the original release, but appeared in pre-release copies of the game and made appearances in promotional art.|
At the end of the third act of each zone (except the Scrap Brain Zone), Sonic faces off against Eggman, who is piloting his Eggmobile. For each battle, Robotnik's machine has a different tactic. Sonic must hit each boss 8 times to destroy it.
- Wrecking ball (Green Hill Zone)
- Fireball shooter (Marble Zone)
- Spike weapon (Spring Yard Zone)
- Retreat (Labyrinth Zone)
- Mine dropper (Star Light Zone)
- Final Zone

Master System and Game GearEdit
As the Master System still had high sales in South America (and in limited amounts in the US through retail stores), an 8-bit incarnation 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 August 4, 2008. This version was also made available worldwide for the Game Gear, with adjustments due to the smaller screen.
The EU/US manual contained the following story prologue:
- Dr. Ivo Robotnik, the mad scientist, is snatching innocent animals and turning them into robots! Only one tough dude can put an end to the evil scheme. It's Sonic, the real cool hedgehog with the spiked haircut and power sneakers that give him super speed. Help Sonic go down platforms and slides. Go into space and do the loop-de-loop until you're dizzy. Free all the animals and become the super hero. Be Sonic! Be atomic!
A translation of the story prologue from the Japanese manual reads:
- The evil mad scientist Dr. Eggman is up to his old nasty tricks again.
"Sonic…that annoying, impertinent hedgehog. Thanks to him, my great plans are always laid to waste! Oh, but this time, I'm going to rub him out with the power of science! Ha ha ha ha ha…"
South Island is a treasure trove of gems and ancient ruins. They say that it's the island where the mystical Chaos Emeralds lie. The Chaos Emeralds are a super-material that give energy to all living beings. Also, when applied to scientific purposes, they can be used for nuclear and laser based weaponry. However, nobody knows exactly how to get ahold of these emeralds. At the same time, though, they do say that the reason why South Island is always moving is because the emeralds are somewhere inside the island's hazy depths.
One day, crisis visited upon the island. And who showed up with it but Dr. Eggman and his cronies.
"I'll find those emeralds even if I have to dig up the entire island to do it!"
Dr. Eggman set up a fort in one corner of the island, and went about carrying out his plan.
"Eggman, you still haven't had enough?"
Sonic hurried as soon as he heard the news. Dr. Eggman never seemed to leave him alone, even though Sonic had beaten him every time so far. It sounded like Dr. Eggman considered Sonic his sworn enemy, but he was never any match for Sonic.
However, this time something is amiss.
"Have you seen it, Sonic? This time is going to be different! Because this time, I've turned all the animals on the island into robots!"
"All of them go about in accordance to my orders. In other words, Sonic, everyone on the island is your enemy! Gya— Ha ha ha ha ha ha ^cough^ ^ack^ ^ahem^. This time, the world really will be all mine!"
This is terrible! Hurry! Sonic the Hedgehog - everyone is waiting for your help!
- 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.
Note: These codes do not work on the Xbox Live Arcade and PlayStation Network versions of the game.
There are six particular glitches in the game that could either help, or mess things up for Sonic very badly.
- 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.
- 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 changed in later games and in certain ports.

- 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 is most subsequent releases. In addition, the scrolling clouds return in most appearances of Green Hill Zone.
