Green Hill Zone

This is the first zone and the easiest. The main dangers are spikes, Buzzbombers, and other small enemies. Try and keep going fast, that way you can avoid more dangers and get to higher up power ups. The Act 3 boss is Robotnik in his Egg-O-Matic with a checker wrecker ball attached to the bottom. Get underneath the platforms when it swings toward you and duck at the edge. It won't hit you. When it swings the other way, jump on the platform and jump at Robotnik's ship. 8 such hits will destroy his ship.

The Marble Zone

This zone isn't as easy as the first one. All this lava makes this zone a hard one. Just try to watch out for the lava. Spikes pop up everywhere, so watch where you're running. A lot of the times this zone requires precise jumping, so be really careful. At the end, Robotnik comes and tries to suck up the lava and drop it on you. Watch out for it and jump at him. 8 hits will put him where he belongs.

Spring Yard Zone

This one's a killer. The first in a long tradition of Pinball Sonic boards - those springs and bumpers get on your nerves after a while. Just keep your head and you'll be cool. Watch out for that rolling ball badnik. He's gets annoying after a while as well and tends to show up in the least expected places. The Act 3 boss is Robotnik with a spike on his Egg-O-Matic. He'll try to drop down on you. Dodge him and hit him. He'll come up with a block, so get rid of him quick or you'll have no platform left to stand on! 8 hits will send him running.

The Labyrinth Zone

Get ready for an underwater extravaganza. Make sure that you keep enough air to survive at all times. Get air bubbles when you can and try to stay on the surface when you can. Other than that, the zone isn't extremely hard. The water slows you down, so be careful. Robotnik is pretty easy in Act 3. All you have to do is get to the top of all his traps. When you do, he'll run away, leaving you to finish the zone.

Star Light Zone

Watch out for the bombs, they're everywhere. Other than those bombs, it's a pretty straightforward zone. To beat the Star Light zone boss, get on one end of the spring that Robotnik doesn't drop the spike ball on. When he drops the ball, it will bounce you up. Bounce up and over him and hit him from the top. Eight hits puts him out.

Scrap Brain Zone

This isn't extremely hard but it isnt exactly easy either. Keep your wits about you though, or you'll be a Sonic pancake in no time! There is no boss at the end of Act 3, which strangely enough is an underwater area. At the end of Act 2 Robotnik sends you plummeting into an underground area with water. Just remember to keep getting enough air to survive.

The Final Zone

Here you must fight Robotnik for the final time. Stay in the far left or far right corners and attack Robotnik when he appears. Be careful, or the 4 pistons he's hiding in will smash you. After the pistons try to cream you, the red light will produce 4 white fireballs. Dodge them. The cycle repeats itself. As always, after 8 hits the pistons will be destroyed. As Robotnik flies off in his Egg-O-Matic, hit the ship to damage it and send Robotnik crashing to the ground. Now sit back and watch the ending.

The Special Stage - The 3D Maze

To get to the Chaos Emerald special stage, have at least 50 rings when you pass the Goal. A large ring will be there. Jump into it to go to the special stage. It's a 360 rotating maze. Jump through it and search for the Chaos Emerald. It will be encased in blocks that disappear when you touch them. Get rid of the blocks and grab the Emerald to win! You also can exit the stage by touching the Goal balls. When you get all 6 Emeralds (there are only 6 in this game), you DON'T become Super Sonic. You just get You just get to see the good version of the ending which isn't much anyway.
