Sonic the Hedgehog/Green Hill

Green Hill Zone, the first zone of the game, is a picturesque paradise with green forests, beautiful blue lakes, and brown checkered soil. Said checkers are meant to symbolize the checkered flag, which is an icon of racing culture. Green Hill has many flowers and palm trees in the foreground, some of which may hold monitors and springs for the player to use, as well as waterfalls with wooden bridges crossing them. The background shows a vast lake, with green forests, sharp mountains and rolling clouds in the distance.

As the first Zone, Green Hill is a very fast-paced level designed to demonstrate Sonic's trademark speed, with many setpieces placed for the player to build as much speed as possible. These include ramps to launch the player into the air, S-shaped tubes that Sonic will automatically roll into, and the famous shuttle loops. There are many pathways for the player to choose should they feel explorative, be it high hills reachable by floating platforms, or hazard-filled lower routes, both often rewarding the player with lots of Rings for reaching them.

Hazards include crumbling platforms and spikes, with swinging platforms to carry the player over these hazards. The lower routes also have the occasional bottomless pit, resulting in instant death if the player falls down one of them. Act 3 also features spinning log bridges that are lined with spikes, so the player must take care when crossing them and jump to avoid the spiky parts.

Act 1

 * Jump and get the game's first three rings, then hop up to the short plateau and jump on the Super Ring.
 * Kill the Buzzbomber as it speeds by to shoot you, then jump to the nearby tree to your right. It's barely visible, but there's a yellow spring hidden in the treetop. Hop on it and you'll shoot upward to five more rings.
 * Go forward past the Chopper jumping up out of the water and then jump in the top of the second tree past that bridge. You'll hit an Invincibility that's there but that you can't see that well.
 * Run forward until you reach a yellow spring opposite a cliff overhang. Jump to that area, but watch out - the cliff overhang crumbles underneath your feet, as do all others that look like this one.
 * Go past about two more of these falling edges until you reach a blue post. It will turn red when you run past it - it's a lamppost. You'll start back at that point should you happen to die.
 * There are two paths here. For the first, run straight forward from that goal point. You'll go through the famous dizzying loop-de-loop that mesmerized gamers in the Genesis' formative months.
 * For the second path, follow the floating platforms up to a cliff.
 * If the first path was taken, Sonic rolls through a tunnel that takes a short break to make room for another checkpoint. Note that this is the only path that contains a checkpoint. You'll shoot up a natural half-pipe of sorts and get a couple of rings in a large trapezoidal formation.
 * If the second path was taken to the highest ledge, you'll be able to run off the platforms that lead Sonic down to the trapezoidal formation of rings, giving you the chance to collect most of them.
 * When you come down, there's a short way to go until you make the exit. If you have 50 rings or more when you get there, there will be a humongous ring above the sign and to its right. Jump into it as you pass the sign and you'll be taken to a rotating special stage where you can try for one of the six Chaos Emeralds. If you don't have fifty rings, pass on to the next act.

Act 2

 * Grab the rings hovering horizontally over the bridge and vertically over the spring, then take a detour to the left.
 * There are spikes to the left of that yellow spring, and if you control your jump right, you can sort of dive past them to a lower area holding twenty rings and a shield, which will allow you to take a hit without causing you to suffer any ring loss.
 * You're now in this bottom pit area (if you made it past the spikes, that is), and you have no apparent way to get out. To do so, start from up against the spikes (you won't get hurt by touching their sides) and run to the wall to the right, pressing before you get in front of it. If executed properly, you'll roll up into a ball and destroy the weak wall ahead of you, which opens up into a more expansive area where you can get an item box containing Power Sneakers.
 * After getting the Power Sneakers, ride the moving ledge above you to the waterfall with rings in front of it. Make your way to the half-pipe ahead, which plants you on a swinging ledge. Get the rings that are in the ledge's path and stop at the tree to the left for a shield if you've lost your other one.
 * Above a loop is a multitude of rings as well as a 1-Up item box. You should be able to reach them with a good amount of speed and a well-timed jump.
 * Some invincibility in a tree to the right will help you blow right through to a checkpoint, though bewaring hazards in this next spiky area is important, as Sonic can get trapped in the pits even with the help of invincibility. Proceed with caution, jumping on each narrow platform carefully until reaching the checkpoint.
 * The path will split in two once again. If in need of a shield, take a left off the cliff to the end of the lower area, then take the swinging platform to the right of the area. Past some more badniks is a spring that should be avoided and an item box containing rings.
 * If taking the upper path, simply run past the crumbling cliff and slide through the tunnel.
 * Go straight ahead from here until you reach the exit (and hopefully, another large ring).

Act 3

 * Hit the top of the second tree from underneath to reveal invincibility, then speed ahead with it.
 * Use the spring to get up to the cliff edge that falls under Sonic's weight and keep progressing up the high road to a shield.
 * Try to stay along this high road until you make a checkpoint.
 * You have two choices here; get the Power Sneakers and speed ahead for a load of rings, or take the high road along the moving platforms and make it to another quick checkpoint. The high road reaps an eventual convenient reward, so take it.
 * When you make the second checkpoint post, ride along the moving ledges until you get to one that just falls. Let it take you down; you'll be on top of a loop-de-loop and right near an accessible 1-Up (the small reward mentioned earlier).
 * Jump down to the left to get a shield out of the palm tree below, then continue through the loop as normal and jump when you reach a small mound in front of the red springboard on the rock to get back on higher ground.
 * Ride the swinging ledge that stops in front of a series of ledges that fall shortly after you land on them. Jump across them to a cliff, above which is more invincibility.
 * Grab the invincibility and run with reckless abandon across the rotating spike log, which normally requires patience and good timing to get past.
 * Continue forward to the platform on a chain swinging very low over a bed of spikes. You'll come to a short curve that will result in you uncovering a Super Ring monitor. Shortly after that, if you get a running start from way back near the bed of spikes and jump at the correct moment, you'll get your third invincibility of the level out of a very tall palm tree. This comes just in time for your first battle with Dr. Robotnik.

Act 3 Battle - Egg Wrecker
The arena for your first bout with Dr. Robotnik consists of a flat surface with two platforms - one on the left and one on the right. Robotnik will enter on his Egg Mobile, drift to the centre of the screen and drop a checkered wrecking ball from below the vehicle, which he will swing back and forth in an attempt to hit you. He requires eight hits to defeat.

A good strategy to defeat him is as follows:


 * As Robotnik is floating on-screen, get on one of the platforms and deal him several hits before the ball is lowered.
 * Stand on a platform and wait for the ball to swing your way, then jump, hit Robotnik and slip through the gap between Robotnik and the ball.
 * Now dash to the area underneath the other platform and wait for the ball to pass, then leap on and get ready to deal another hit.

The the final hit is landed, Robotnik's Egg Mobile will be racked by explosions and the ball will fall off. The beaten scientists will hastily retreat, allowing you to reach the animal capsule and open it, completing the zone.
