After acquiring the Light Shoes (and Crystal Ring to speed up the process), go to the Casino area and step on the button to make the rings appear. Do this by repeatedly for more starting rings. Note: The ring limit can exceed 999, but you cannot tell exactly how many you have. Listen for the extra life sound to keep track of them. When satisfied, go to Emerald Coast and complete the level without getting hit. You will be awarded with the rings you collected at the end. Go to the Chao Garden, then the Black Market, and spend your hard earned coins.

Duplicating the Black Chao Egg

-On the Egg Carrier as E-102, when you let Amy out, the cell next to her's has an orange-spotted black egg in it. Jump on the button in front of the cell to open it, then take the egg and exit from the prison area.You will then be in the Hedgehog Hammer room. Drop the egg into the middle of the platform where there is a round grate. The egg will fall right through the floor. Return to the prison area and there will be two black eggs now in the cell. (NOTE: you can only duplicate the egg once, so take one egg and hatch it in the chao garden, then go back and clone it again!)

Free rings hint

As Tails, go to any place with grass and wack the dark green weed with your tail. If you are lucky, a ring or extra life may appear. As Knuckles and with the Silver knuckle gloves, go to a place where you can dig and in most places (especially places with plants) you can uncover up to 20 rings.

Cream the Rabbit cameo

When exiting the Casinopolis action stage in any character's story, you can see Cream the Rabbit flying by. Be quick to look though as she only flies by for a short time each time.

Two Knuckles at once

Play through the game with every character until you get Super Sonic. In Super Sonics Adventure, go to the crashed island to see Knuckles and Eggman (Robotnik). After the clip, press A+B+X+Y+Start, then select Knuckles. Go to the same place and there are two Knuckles! This works with other characters, too, but it's not as funny.

Sonic's different snowboards

Before entering the snowboarding part of the ice stage, press X to get Sonic's blue snowboard (previously seen in Sonic 3 and Sonic Triple Trouble), or ress B to get Sonic's yellow board (only seen in Sonic Adventure.)

Chao Race Sonic Tokens

You can earn 5 Sonic Tokens from the Chao Race. Simply raise a chao and go to the Chao Race, then choose the first choice and place where your chao is. Then, select a crystal and win each one. A 5th one will appear and choose it. If you have trouble finding levels you have beat and want the tokens, go to the main options at select the second option. You can go to any level you have beaten without running around for it. This is good if you need to collect more tokens, and it tells you which ones you have gotten and where. There are Tokens hidden around the world, which shouldn't be to hard to find.

Two players

When you are playing Sonic's action stages and Tails is on the screen, a second player can control Tails via a second controller. Any rings Tails collects are added to Sonic's totals. However, do not make Tails break open any shields, invisibilities or One Up item boxes as those will not be added to Sonic and will be wasted.

Sonic Chao

Give a Chao about 20 of the pink animals (rabbits, kangaroos, deer) to make it look like everyone's favorite hedge hog.

Golden Chao baby

There are two open shops in the part of Station Square with the open manhole; the golden chao's egg is in one of them. However, every time you lift the egg from its pressure sensitive platform, the doors are barred shut. Go to the city hall area where you fought Chaos 0 and look near the walls and grass. An egg-shaped rock is here, which you can put on the platform in the store. You may now leave freely with the golden Chao egg.

Easy Emblems as Knuckles hint

If struggling to get the 1 minute emblems as Knuckles, here is a trick that will make it much easier. Find the first emerald shard but don't touch it! Instead, pause the game and restart the level. Then, run to it as fast as you can. Since the shards act as save-points, find the next one and repeat. Do this until you have all three.

Drive with anyone in Twinkle Circuit

After completing the game with all six characters, you can race in Twinkle Circuit with anyone. Simply choose the character you want and go to station square. Once there, go over to the little patch of grass and weeds by speed highway entrance and pick up the ticket. (It will be rotating and thus easy to spot.) Then, go into the Twinkle Park building and, instead of entering Twinkle Park, enter Twinkle Circuit. You will hear a special noise that tells you that the secret is unlocked. Repeat the process for all the characters.

Change View in Twinkle Park Race

To change the view duing Twinkle Park Race, press UP to toggle between inside, outside, and far out view. This also works when playing the first bumper car portion of the level.

Aztec Forest shortcut

It is possible to get to the Frog and the Emerald as Tails in one step. After riding the trolley to the Aztec Forest, you will be standing up high on a platform overlooking the forest. Stand on the edge and look down to the left to see two trees sticking out of the canopy that are close together. Fly toward the trees and land next to the one that is closest to the ledge you jumped from. You should be standing on top of the canopy. Walk around the first tree until you fall through the canopy and end up right next to the emerald and the frog.

Killing your Chao

Easier Emblems with Big

On the levels where you have to catch 1000g of fish, catch at least one 500g fish then catch Froggy. Froggy weighs 500g and will thus allow you to complete the stage.
