Complete the Game
You finished the game.
You need to complete all the stages in the game.
You collected a Chaos Emerald.
In each stage, there are giant rings scattered about. All you need to do is find one of these rings and jump through it to enter the Special Stage. Once in the Special Stage, you need to touch all blue spheres in the game to collect them, and making large squares with them by running through the spheres makes things go much quicker. You need to grab all spheres in order to get a Chaos Emerald. Be sure to save before you start a Special Stage incase you happen to mess up along the way, so you don’t have to start all over, though there are plenty of rings throughout the game.
You collected all seven Chaos Emeralds.
You need collect all 7 of the Chaos Emeralds in the game. You need to finish a Special Stage, which you enter by going through giant rings found throughout each stage. You can find various guides that show the locations of the emeralds, as well as all Special Stages on Youtube.
You scored 20,000 points.
You need to score 20,000 points at one time. See Points III for more information on how to earn enough points quickly.
You scored 40,000 points.
You need to score 40,000 points at one time. See Points III for more information on how to earn enough points quickly.
You scored 80,000 points.
A lot easier then it sounds. Just aim to get as many points in each stage you play, and in every special stage make sure you collect the spheres in squares to earn extra points. Be sure to save your progress, and once in a while set up some backup save points just incase. But, if you enter each ring and make squares, collect as many rings as possible, and hit as many enemies as you can, you should have no problem getting this and the other Point achievements early in the game.
You got a blue gumball.
Have 50 rings total on you when you go by a Checkpoint sign post. When you do, a ring of stars will appear above the sign post, and you must jump through them. You can save your progress here to make things easier in case you mess up. Just keep hitting the gumball switch until you get a blue gumball.
