Go to any Chao Garden and go near one of the trees. When the coconut or fruit falls off, you can sell it at the Black Market. It does not sell for much, but is worth something. You will get 10 rings for the coconuts.

Go to the Chao Garden. After your Chao has hatched, take the egg and go to the Black Market. Sell your egg shell for the following prices.

Normal egg: 50 rings
White egg: 100 rings
Red egg: 120 rings

Get the Light Dash ability and go to Metal Harbor. Whenever the large rows of rings are ahead of you, use the Light Dash move. This is a very fast and easy way to get rings.

Get something that sells for a lot of rings. If you do not have many, get an old pot and use it for this trick. If you have the time, get a Shiny Egg Shell (recommended). You cannot sell the egg -- you can only sell the shell. Go to the Black Market with the egg and you sell it. then. Exit out of the Black Market and while still in the Kindergarten, hold B + Start + X for about two seconds to reset your game (without saving the Chao data but saving the game data). Since the Chao data did not save, the game believes the egg is still there, while the saved game data records that you sold the egg for a couple thousand rings. You will get the egg and the money back. Repeat this (sell the shell, reset game, then go back to the garden) to end up with lots of rings.

Play Sonic's first level under "Find The Lost Chao". Keep going through the level without getting the Chao until you get 999 rings, which is the maximum number. Then, get the lost Chao .and it will add 999 rings to your game. This is helpful if you want to get a beanie for your Chao later in the game.

On the first level, select the third mission on stage selection screen. Go through the level until you have 999 rings. Then, after you run down the building, do not hit the bouncers and go to the right. Play the Mystic Melody and work your way to the top. Repeat this to get as many rings as needed.

In City Escape level, you can get more than 425 rings. This will give you more rings for the Choa Gardens in just one level. You can also get more than 435 rings if you get all the rings, including the Light Dash rings after you break the iron box after the street boarding part at the very beginning of the stage.

Unlock the racing game (just route 101 or 280). If you got a "D" or "E" rank on the first mission, it would be easier for you to do mission 2 (get at least 100 rings). If you got "A", "B", or "C" rank, just do mission 1 (get at least 200 rings and also get 2 extra lives).

For quick and easy rings, just go to the City Escape level and collect 300 rings every visit.

Use the following trick to get 100 rings in any level, especially Rouge's and Knuckle's stages. Collect as many rings as you can, then go to the back ring. You will start the level over with all of your rings, and will be able to recollect them.

Go to any level as Sonic or Shadow. Choose the third mission (find the lost Chao) and go through the level collecting rings. Do not get the Chao. Go to the end of the level. When you hit the goal ring, you will be taken back to the beginning of the level. You will have all of your rings and all the rings originally on the course will be back. Repeat this until you have as many rings as needed.

Go to the Black Market after you have collected 70 emblems. Buy a Shiny Yellow Egg (7000 rings) and hatch the Chao. His egg shell is worth 1200 rings.
